When someone offers you a job in Seoul, New York, London, or Tokyo, the instinct is to compare the numbers on the contract. But gross salary figures are close to meaningless for cross-city comparisons. After taxes, social insurance, and housing — the three variables that differ most dramatically between these cities — the ranking of which city “pays best” can flip entirely.
This guide uses 2026 tax schedules, official government wage data, and real housing transaction figures to calculate what actually happens to your salary in each city — and where your money goes furthest.
1. Why Comparing Salaries Across Cities Is Harder Than It Looks
Three separate distortions make raw salary comparisons unreliable.
Currency fluctuation: The Japanese yen has weakened significantly against USD in recent years. A Tokyo salary that looks 30% lower than a Seoul equivalent in dollar terms may represent similar or greater local purchasing power for domestically-priced goods. Conversely, London salaries look higher in USD terms than they did three years ago due to pound recovery.
Tax and deduction structure: The difference between gross and net salary varies by 10–15 percentage points between these cities at mid-income levels. A $70,000 gross salary in New York City nets approximately $49,000–52,000 after federal, state, and city taxes plus FICA. The same gross in Seoul nets roughly $58,000–60,000. That $8,000–10,000 annual difference starts before you’ve paid for anything.
Housing cost variability: Housing is the largest single expenditure in all four cities, but its proportion of income varies from 27% (Seoul average earner, central 1BR) to over 85% (New York average earner, central 1BR). This single variable explains most of why Seoul professionals can save money when their New York counterparts cannot.
2. Average Salaries: What People Actually Earn
The figures below represent reported average monthly net (after-tax) salaries from Numbeo February 2026 data and official government statistics. Median salaries would be 15–25% lower in all cities due to high-earner skew.
| City | Average Monthly Net Salary | Average Monthly Gross (est.) | Data Source |
|---|---|---|---|
| Seoul | ~$3,220 (₩4,665,780) | ~$3,900 (₩5,650,000) | 고용형태별 근로실태조사 2026 |
| Tokyo | ~$2,662 (¥396,638) | ~$3,200 (¥476,800) | Numbeo Feb 2026 |
| New York | ~$5,264 | ~$7,200–7,800 | Numbeo Feb 2026 |
| London | ~$3,850 (£3,040) | ~$5,200 (£4,100) | ONS / Numbeo Feb 2026 |
Seoul’s average monthly wage from the 고용형태별 근로실태조사 (Employment Type Wage Survey) is approximately ₩4,094,615 across all industries and employment types. The Seoul metropolitan area figure is somewhat higher. Using the February 2026 rate of 1 USD = 1,449 KRW, this equals approximately $2,826/month — slightly below the Numbeo reported figure, which skews toward full-time salaried positions.
Tokyo’s nominal salary figure looks low against New York and London, but this partially reflects yen weakness. For local spending — food, transport, domestic entertainment — purchasing power is closer to Seoul’s than the dollar comparison suggests.
3. Tax and Social Insurance: What Gets Deducted First
Before you see a single dollar of your salary, governments take their share. The structure varies considerably between cities.
| Gross Annual Salary | Seoul | Tokyo | New York | London |
|---|---|---|---|---|
| $30,000 total deductions | ~$3,150 (10.5%) | ~$4,200 (14.0%) | ~$5,400 (18.0%) | ~$3,900 (13.0%) |
| $50,000 total deductions | ~$7,210 (14.4%) | ~$8,500 (17.0%) | ~$11,200 (22.4%) | ~$9,320 (18.6%) |
| $70,000 total deductions | ~$11,900 (17.0%) | ~$14,700 (21.0%) | ~$17,500 (25.0%) | ~$16,100 (23.0%) |
| $100,000 total deductions | ~$18,500 (18.5%) | ~$24,000 (24.0%) | ~$29,000 (29.0%) | ~$28,000 (28.0%) |
Seoul tax structure: Korea applies a progressive income tax from 6% to 45%, plus a 10% local income tax on the national tax amount. Employee social insurance contributions total approximately 9.7% of gross salary (National Pension 4.5%, Health Insurance 3.545%, Employment Insurance 0.9%, Long-term Care Insurance 0.9%). Foreign employees in Korea have an additional option: a flat 19% income tax (20.9% including local income tax) available for up to 20 years under the Restriction of Special Taxation Act (조세특례제한법). At higher income levels ($70,000+), this flat rate can be more advantageous than the progressive system.
New York tax structure: Federal income tax (10–37% brackets), New York State income tax (4–10.9%), New York City income tax (3.078–3.876%), and FICA (Social Security 6.2% up to the wage base, Medicare 1.45%) combine to create some of the highest effective tax rates among major US cities. A $100,000 gross salary in NYC nets approximately $68,000–72,000.
London tax structure: Income Tax (20% basic rate, 40% higher rate above £50,270 in 2026/27), National Insurance contributions (8% employee rate on earnings between £12,570–£50,270), and no additional city-level tax. The 2026/27 HMRC thresholds mean the 40% higher rate kicks in at roughly $63,000, making London’s effective rates steep for mid-high earners.
Tokyo tax structure: National income tax (5–45% progressive), residence tax (~10% of taxable income, billed the following year), and social insurance contributions (approximately 15% of gross for employees in national health insurance and pension). Japan’s residence tax creates a cash flow challenge in the first year of employment since it’s based on prior-year income.
4. Housing Costs: The Biggest Variable
Housing is where the salary comparison becomes real. After deductions and housing, what’s left for everything else?
| Housing Metric | Seoul | Tokyo | New York | London |
|---|---|---|---|---|
| 1BR City Centre (monthly rent) | ~$861 | ~$1,163 | ~$4,461 | ~$2,650 |
| 1BR Outside Centre (monthly rent) | ~$548 | ~$642 | ~$2,778 | ~$1,800 |
| Rent-to-income ratio (avg earner, central 1BR) | ~27% | ~44% | ~85% | ~69% |
| Average 1BR rent in Seoul (all areas) | ~$822 (₩1,190,000) | — | — | — |
The Seoul figure of ₩1,190,000/month (~$822) for average 1BR rent across all areas comes from 아파트(전월세) 실거래가 data published by the Ministry of Land, Infrastructure and Transport. This covers actual registered lease transactions across Seoul districts — not survey estimates. In practice, rent varies enormously by district: Gangnam-gu averages ₩1.8–2.5M/month, while areas like Nowon-gu or Dobong-gu can be found for ₩600–800K/month for reasonable quality.
Seoul’s jeonse system provides a structural alternative unavailable in other cities. Under jeonse, tenants pay a large lump-sum deposit (typically ₩200–500M for a 1BR in Seoul) and pay zero monthly rent. The deposit is returned in full at lease end. For tenants with access to capital — or who can secure a jeonse loan at current rates of roughly 3–4% annually — the effective monthly housing cost can drop to $250–400/month, dramatically improving the disposable income calculation.
London’s housing market has tightened significantly since 2023. A 1BR in central London (Zone 1–2) runs £2,000–2,400/month (~$2,520–3,020) in 2026, with Zone 3–4 options starting around £1,400–1,700. The rental-to-income ratio for an average London earner now approaches 65–70%, creating financial pressure comparable to New York.
5. Real Purchasing Power After Housing
The most meaningful comparison is disposable income — what remains after tax deductions and housing costs are subtracted from net salary. This is what actually funds your daily life, savings, and discretionary spending.
| Scenario | Seoul | Tokyo | New York | London |
|---|---|---|---|---|
| $30,000 gross: annual net salary | $26,850 | $25,800 | $24,600 | $26,100 |
| $30,000 gross: minus annual rent (central 1BR) | $16,518 | $11,844 | -$28,932 (deficit) | -$5,700 (deficit) |
| $50,000 gross: annual net salary | $42,790 | $41,500 | $38,800 | $40,680 |
| $50,000 gross: minus annual rent (central 1BR) | $32,458 | $27,544 | -$14,732 (deficit) | $8,880 |
| $70,000 gross: annual net salary | $58,100 | $55,300 | $52,500 | $53,900 |
| $70,000 gross: minus annual rent (central 1BR) | $47,768 | $41,344 | -$1,032 (near-deficit) | $21,100 |
The results are striking. At a $50,000 gross salary — a reasonable mid-career benchmark in all four cities — Seoul leaves $32,458 after tax and central rent. New York leaves a $14,732 deficit. That’s a $47,190 annual difference between the same gross salary in two different cities.
Even at $70,000 gross — where New York salaries start becoming more competitive — a New York earner renting centrally barely breaks even on housing alone. A Seoul earner at the same gross salary has $47,768 annually available for everything else: food, transport, savings, and discretionary spending.
Note: These figures use central 1BR rent as a benchmark. Outer-area rentals improve New York and London’s figures significantly (outer New York at $2,778/month would leave $19,236 annually at $70K gross), but Seoul’s outer-area rent ($548/month) makes it even more favorable in that scenario.
6. Career-Specific Comparison: IT, Finance, Teaching, Engineering
The general comparison changes significantly by profession. Some careers pay substantial premiums in specific cities that alter the overall financial calculation.
| Career | Seoul (monthly gross) | Tokyo (monthly gross) | New York (monthly gross) | London (monthly gross) |
|---|---|---|---|---|
| Software Engineer (mid-level) | ₩5.5–8M (~$3,800–5,500) | ¥500–800K (~$3,350–5,370) | $9,000–15,000 | £5,000–8,500 (~$6,300–10,700) |
| Finance/Investment Banking (junior) | ₩5–7M (~$3,450–4,830) | ¥500–700K (~$3,350–4,700) | $12,000–20,000+ | £6,000–10,000 (~$7,600–12,600) |
| English Teacher (native speaker) | ₩2.5–3.5M (~$1,725–2,415) | ¥250–350K (~$1,680–2,350) | $4,000–6,000 (NYC public school) | £2,500–3,800 (~$3,150–4,800) |
| Mechanical Engineer (mid-level) | ₩4.5–6.5M (~$3,100–4,485) | ¥400–600K (~$2,685–4,027) | $7,000–10,000 | £4,000–6,000 (~$5,040–7,560) |
| University Lecturer | ₩4–6M (~$2,760–4,140) | ¥400–700K (~$2,685–4,698) | $6,000–9,000 | £3,500–5,500 (~$4,410–6,930) |
IT professionals face the clearest city-specific trade-off. New York and London tech salaries significantly exceed Seoul equivalents, but after housing costs, a senior Seoul software engineer earning ₩8M/month (~$5,500) retains more disposable income than a junior New York engineer earning $12,000/month once central rent is subtracted. The New York tech premium only clearly wins at senior or principal engineer levels ($15,000+/month), where housing represents a smaller proportion of income.
Finance professionals present the strongest case for New York. Investment banking and trading compensation in New York vastly exceeds all other cities, particularly at the senior level. If your goal is maximum wealth accumulation through finance, New York’s premium over Seoul or Tokyo at the top end is too large to ignore — even accounting for higher costs.
English teachers in Seoul receive housing provided or subsidized by the employer in most contracts (EPIK, SMOE, and many hagwon positions), which changes the calculation dramatically. An English teacher earning ₩2.5–3M/month with free or subsidized housing in Seoul can save $1,000–1,500/month — impossible in New York or London on a teacher’s salary.
Engineers in manufacturing, semiconductor, and electronics fields find Seoul particularly competitive. TSMC, Samsung Electronics, SK Hynix, and POSCO compensation packages at the engineer level rival or exceed Tokyo equivalents, with Seoul’s lower living costs providing genuine financial advantage.
7. The Hidden Costs: Healthcare, Pension, Social Costs
Healthcare
Seoul: The National Health Insurance (NHI) system covers all residents including foreign workers. Employee contribution: 3.545% of gross salary (employer matches). Out-of-pocket costs for doctor visits are typically $5–20 for a GP, $20–50 for a specialist, and hospital stays are covered at 80% or more. Dental and vision are partially covered. Total annual healthcare cost for a healthy young professional: $1,500–2,500 including premium.
New York: Employer-sponsored health insurance is common but not universal. Employee contributions to premiums range from $200–600/month depending on plan quality. Deductibles of $1,000–3,000/year are standard. A healthy young professional’s annual healthcare cost: $3,000–8,000+ including premiums, deductibles, and co-pays. This is a major hidden cost that rarely appears in salary comparisons.
London: NHS provides free-at-point-of-use healthcare funded through National Insurance contributions (already included in the tax deductions above). Effective healthcare cost burden is low, though wait times for non-urgent NHS care have lengthened. Private supplemental insurance is optional but common for professionals.
Tokyo: Shakai Hoken (employee health insurance) covers 70% of medical costs, with employee contributions approximately 5% of gross. Doctor visits: $5–15 out of pocket. Total annual healthcare cost for an employee: roughly $2,500–4,000 including premiums.
Pension
Korea: National Pension (국민연금) contribution: 4.5% of gross salary (employee share, employer matches 4.5%). Contributions accrue toward retirement benefits. Korea has social security agreements with 38 countries as of 2026, allowing pension portability for many nationalities. Foreign workers staying fewer than 5 years may be eligible for a lump-sum refund of contributions upon departure.
Japan: Kosei Nenkin (Employee Pension Insurance): approximately 9.15% of gross (employee share, employer matches). Foreign nationals in countries with social security totalization agreements may be exempt from contributing to both Japanese and home-country pension systems simultaneously.
United States: Social Security: 6.2% on wages up to the taxable wage base ($176,100 in 2026), plus Medicare 1.45% (already included in tax deduction figures). Foreign nationals on certain visa types may be exempt from Social Security and Medicare taxes.
United Kingdom: National Insurance contributions (employee rate: 8% on earnings £12,570–£50,270) fund state pension and NHS. Already included in the deduction figures above.
8. Which City Offers the Best Financial Outcome?
The answer depends heavily on your income level, career field, and time horizon.
Seoul is the strongest choice for:
- Median-to-above-average earners who want to accumulate savings — Seoul is structurally the only city of the four where an average earner can comfortably cover living costs and save simultaneously
- Early-career professionals building financial cushion before higher-cost markets
- Anyone accessing jeonse financing — the effective monthly housing cost drops below $300–400, making monthly surpluses of $1,500–2,000+ achievable even on moderate salaries
- Tech and engineering professionals at Samsung, SK Hynix, or the broader chaebol ecosystem — compensation is competitive and cost of living is low
- Foreign workers using the 19% flat tax — this can represent $5,000–10,000 in annual tax savings versus progressive rates at mid-high income levels
New York is the strongest choice for:
- Senior finance and investment banking professionals — compensation packages at VP level and above in New York are impossible to match in Seoul or Tokyo
- Top-tier tech talent (senior engineer, principal, staff) earning $200,000+ — at this level, New York’s premium overcomes its cost disadvantage
- Career-stage periods where being in the world’s financial capital provides network and opportunity value that transcends monthly savings
London is the strongest choice for:
- European finance and fintech professionals — London remains the dominant financial hub for European business
- Professionals who value NHS healthcare, EU proximity, and English-language working environment with less extreme costs than New York
- Those earning above £60,000+ annually, where London’s salary premiums in certain sectors (finance, law, media) become meaningful
Tokyo is the strongest choice for:
- Japanese-language professionals in finance, trading, or niche manufacturing sectors
- Dual-income households, where Tokyo’s individual income deficit disappears with two salaries
- Those prioritizing safety, quality of life, and infrastructure over maximizing financial savings
5b. Food Costs: Eating In and Eating Out
Grocery shopping is more competitive between the cities than most people expect. The real gap shows up at restaurants — Seoul and Tokyo are affordable; New York is not. Source: Numbeo February 2026
| Food Item | Seoul | Tokyo | New York |
|---|---|---|---|
| Meal, inexpensive restaurant | $9.00 | $7.58 | $25.00 |
| Meal for 2, mid-range restaurant | $45.00 | $50.00 | $100.00 |
| Fast food combo meal | $7.50 | $6.75 | $15.00 |
| Cappuccino | $3.60 | $4.50 | $6.50 |
| Chicken breasts (1kg) | $6.20 | $7.50 | $14.50 |
| Eggs (12) | $3.00 | $2.50 | $5.50 |
| Monthly groceries (single person) | ~$250–350 | ~$280–380 | ~$450–600 |
Seoul’s food delivery ecosystem (Baemin, Coupang Eats) is among the cheapest globally. A full Korean meal delivered runs $8–14 including fees. The New York equivalent via DoorDash or Uber Eats typically reaches $25–40 after platform fees, delivery charge, and tip. For grocery shopping, Seoul’s large discount chains (Emart, Homeplus) offer competitive prices on staples, and local markets (시장) undercut supermarket prices significantly for produce and protein.
5c. Transport: The Clearest Category Gap
Seoul’s public transit is one of the most cost-effective urban systems among major developed economies. The gap with New York is not marginal — it’s structural. Source: Numbeo February 2026; Seoul Metropolitan Government
| Transport Cost | Seoul | Tokyo | New York |
|---|---|---|---|
| Monthly transit pass | ~$45 | ~$77 | ~$132 |
| Single metro ride | ~$1.10 | ~$1.75–2.50 | ~$2.90 |
| Taxi start (base fare) | ~$3.40 | ~$5.40 | ~$3.00 + metered |
Seoul’s K-pass (케이패스) system, launched in 2024, provides monthly transit rebates of 20–53% depending on usage frequency — pushing the effective monthly cost even lower for regular commuters. The 23-line metro network connects to surrounding Gyeonggi Province, which means most residents can live and work entirely without a car. Tokyo’s transit is excellent but priced by distance; a monthly commuter pass from a distant suburb can run $150–200.
5d. Utilities, Phone, and Internet
Source: Numbeo February 2026; Speedtest Global Index 2025
| Utility | Seoul | Tokyo | New York |
|---|---|---|---|
| Basic utilities (85sqm apartment) | ~$110–140 | ~$130–170 | ~$180–250 |
| Internet (60 Mbps+, unlimited) | ~$28 | ~$45 | ~$65–80 |
| Mobile phone plan (10GB+) | ~$30–45 | ~$40–60 | ~$60–80 |
South Korea ranks consistently in the global top 3 for internet speed — median download exceeds 230 Mbps nationally (Speedtest Global Index 2025) — at prices well below New York or Tokyo. A fiber connection with 500 Mbps–1 Gbps runs $25–35/month. New York’s internet costs are inflated by limited ISP competition in many buildings. Seoul’s MVNO market also offers usable mobile plans from $15–20/month, though the major carriers (SKT, KT, LG U+) deliver more consistent coverage at $30–45 for unlimited data.
5e. Annual Savings Potential: The Real Bottom Line
The clearest summary metric is annual savings — what a local average earner actually keeps after covering rent and non-housing expenses. Source: Numbeo February 2026; 고용형태별 근로실태조사 (Employment Status Survey) 2025; US BLS 2025; Japan Statistics Bureau 2025
| Metric | Seoul | Tokyo | New York |
|---|---|---|---|
| Average annual net income | $38,640 | $31,944 | $63,168 |
| Annual housing cost (central 1BR) | $10,332 | $13,956 | $53,532 |
| Annual non-housing expenses | $12,060 | $13,836 | $24,744 |
| Annual savings (average earner) | $16,248 | $4,152 | −$15,108 (deficit) |
| Savings rate | ~42% | ~13% | −24% (deficit) |
Seoul’s ~42% savings rate for an average earner is exceptional by global standards — the OECD household savings average hovers around 5–10%. A 25-year-old Seoul professional earning the average salary and saving ₩1.3–1.6M/month can accumulate a meaningful jeonse deposit or investment portfolio within 5–7 years. The same timeline in New York on an average salary produces a deficit, not savings.
8b. What Seoul Is Not Cheaper For
Seoul’s overall cost advantage over New York is real — but it’s not uniform across every category. A few areas buck the trend. Source: Numbeo February 2026; Korea Customs Service 2025
- Imported goods: Korea’s agricultural and consumer goods tariffs make foreign cheese, wine, and specialty food items meaningfully more expensive than US prices. A bottle of European wine that costs $15 in New York can run $25–35 in Seoul.
- International school education: Costs are comparable to or higher than New York private school fees — typically ₩25–40M/year per child ($17,000–27,600), which strains family budgets even in Seoul’s otherwise lower-cost environment.
- Foreign brand clothing: Import markups make brands like Nike, Zara, and H&M more expensive than their US retail prices. Buying the same item in the US and carrying it to Seoul is often genuinely cheaper.
- Specialty coffee: Seoul’s café culture prices for quality specialty coffee ($5–7 per cup) match New York’s — this is one category where the cost advantage disappears entirely.
8c. Lifestyle Quality Differences Worth Knowing
Cost figures don’t capture everything. Several practical differences affect daily quality of life across the cities.
- Safety: Seoul consistently ranks among the world’s safest major cities — Numbeo Crime Index approximately 23, versus New York at approximately 51 (lower = safer). Walking at night, leaving a bag at a café table, or using the subway at 2am are all genuinely lower-risk activities in Seoul than in New York. Source: Numbeo Crime Index February 2026
- Healthcare access: A Korean clinic visit costs ₩10,000–25,000 ($7–17) with NHI coverage, versus $200–500+ uninsured in New York. Even with employer insurance, New York healthcare involves deductibles, co-pays, and billing complexity that Seoul simply doesn’t. Source: NHI Korea 2025
- Commute: Seoul’s subway system covers the entire metro area — clean, fast, and cheap. Average commute times for central workers are competitive with New York, and the transit experience is markedly more reliable.
- Food variety: New York has broader international food diversity at all price points. Seoul excels at Korean food and a narrower but growing range of international options, with Western-style restaurants typically priced higher than Tokyo equivalents for comparable quality.
- Nightlife cost: Going out in Seoul costs materially less than New York — soju and Korean beer at convenience stores run $2–4, and most venues don’t add service charges. A comparable night out in New York costs two to three times as much.
- Work culture: New York’s work culture varies widely by industry. Seoul’s traditional companies are demanding with long hours, though the 52-hour weekly cap is now broadly enforced. International companies in Seoul offer more predictable environments for foreign workers.
9. Frequently Asked Questions
What is the average salary in Seoul for foreigners?
Average salary for foreign workers in Korea varies by job category and visa type. English teachers (E-2 visa) typically earn ₩2.2–3.2M/month (~$1,520–2,210). Professionals on E-7 or F-series visas in tech, finance, and engineering typically earn ₩4–8M/month (~$2,760–5,520). The overall Seoul metropolitan area average monthly gross wage is approximately ₩4.09M (~$2,826) across all workers including Koreans.
Is Seoul a good city to save money?
Yes, relative to other global cities of comparable status. An average-salaried professional in Seoul (₩4M net/month, ~$2,760) paying ₩900K/month in rent (outside centre) has approximately ₩1.8–2.2M/month (~$1,240–1,520) available after housing, food, and transport. This gives a realistic savings rate of 30–40% — significantly above what most New York or London professionals can achieve on equivalent career stage salaries.
How does Korea’s 19% flat tax work for foreigners?
How does Korea’s 19% flat tax work for foreigners?
Foreign employees working in Korea can elect to pay a flat 19% income tax rate (20.9% including local income tax) on their employment income, instead of the progressive rates. This option is available under Article 18-2 of the Restriction of Special Taxation Act (조세특례제한법). It can be applied for up to 20 years of working in Korea. The flat rate is generally more advantageous at incomes above approximately $50,000–60,000 annually, where the progressive rate would otherwise push effective rates above 19–20%. Application is made through the employer at the time of withholding tax calculation.
After taxes and rent, which city pays the best?
At salaries below $70,000 gross annually, Seoul clearly provides the most disposable income after tax and central rent. At $50,000 gross, Seoul leaves approximately $32,458/year after tax and central rent, versus London at $8,880, and New York and Tokyo at a deficit. Above $100,000+ gross, New York’s salary premiums in finance and senior tech begin to outweigh its cost disadvantages for high-earning professionals.
What are the social insurance deductions in each city?
Employee social insurance contributions as a percentage of gross salary (2026 estimates): Seoul approximately 9.7% (National Pension 4.5%, Health Insurance 3.545%, Employment Insurance 0.9%, Long-term Care Insurance 0.9%), Tokyo approximately 14–15% (Health Insurance ~5%, Pension ~9.15%), New York approximately 7.65% FICA only (Social Security 6.2%, Medicare 1.45%), London approximately 8% NI on earnings between the primary and upper earnings limits.
Can foreigners access Korea’s National Pension?
Foreign nationals working in Korea are generally required to contribute to the National Pension, with some exemptions based on reciprocal agreements between Korea and your home country. As of 2026, Korea has social security totalization agreements with 38 countries. If your home country has such an agreement, you may be exempt from Korean pension contributions. Foreign workers who do not qualify for a pension (minimum 10 years of contribution for basic entitlement) and who are leaving Korea permanently may be eligible for a lump-sum refund of their contributions. Check the National Pension Service (NPS) website for current country-specific details.
Is London or New York more expensive?
New York is more expensive than London in most categories, especially housing and dining. A central 1BR in New York costs approximately $4,461/month versus approximately $2,650 in London. Food and entertainment costs are also higher in New York. However, London’s higher income tax (40% on earnings above ~$63,000) partially offsets this by reducing net salary more sharply at mid-high income levels. The net financial position of a $70,000 earner is similar in both cities, with London slightly ahead due to NHS covering healthcare costs.
What is the real monthly take-home in Seoul after all deductions?
For a Korean employee earning the Seoul metropolitan average gross of approximately ₩5,650,000/month, total deductions (income tax + local tax + social insurance) run roughly ₩900,000–1,100,000/month, depending on deductions and family status. This leaves a net monthly take-home of approximately ₩4,500,000–4,750,000 (~$3,105–$3,278). For foreign workers using the flat 19% tax rate, the calculation differs — total deductions at this salary level under the flat rate would be approximately ₩1,100,000–1,200,000/month, or slightly higher than the progressive rate at this income level, making the progressive rate better for this salary range. The flat rate advantage begins at higher income levels.
How do pension and retirement savings compare across the four cities?
Korea’s National Pension replaces approximately 40% of average income at retirement, one of the lower replacement rates among OECD countries. This means Korean workers need more private retirement savings than, say, Japanese workers. However, Korea’s Retirement Pension (퇴직연금) system — mandatory for companies with more than one employee — requires employers to set aside 1/12 of annual salary as severance or retirement pension each year. After one year of employment, workers are entitled to this severance (퇴직금). This effectively represents an additional 8.3% annual compensation that doesn’t appear in monthly salary figures. Japan has a similar enterprise pension system. New York and London workers must rely more heavily on private 401(k)/ISA contributions for retirement savings beyond state pension entitlements.
