United StatesRelocate from South Korea to United States
What it takes to move from South Korea (anchored to Seoul) to United States (anchored to New York). Cost delta, salary required, scoring on four axes, and the operator's tooling stack.
South Korean relocations to the US surged 267% over the period, though quality of life dropped 11.7 points—migrants are trading stability for income, with median US earnings reaching $96,616.
This reversal mirrors broader brain drain patterns where skilled workers accept lifestyle compromises for wage premiums unavailable at home.
If considering this move, stress-test whether the income gain ($96k baseline) covers childcare, healthcare, and housing costs in your target US city before committing.

Each axis is a weighted aggregate of underlying indicators normalized to a 0–10 scale. Weights are explicit and disclosed per axis. The composite is the unweighted mean of the four axes — axes are not collapsed further because the underlying trade-offs (e.g. low cost vs poor air quality) are user-dependent.
Affordability
- Cost-of-living index (weight 60%)100
- Rent index (weight 40%)100
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For New York: ((100 − 100)/100 × 0.6 + (100 − 100)/100 × 0.4) × 10 = 0.
New York is among the more expensive cities tracked. Salary expectations should be calibrated to the high cost base before relocating.
Quality of life
- Safety index (weight 40%)55
- Healthcare index (weight 35%)70
- Air quality index (weight 25%)60
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For New York: (55/100 × 0.4 + 70/100 × 0.35 + 60/100 × 0.25) × 10 = 6.2.
New York has a mixed quality profile. Safety: good; healthcare: good; air: good. Weigh the weakest axis against your personal priorities.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)280 Mbps
- Effective income tax (lower = better) (weight 30%)17.0%
- Cost-of-living (lower = better) (weight 25%)100
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For New York: (min(280/300, 1) × 0.45 + (1 − 0.17) × 0.3 + (100 − 100)/100 × 0.25) × 10 = 6.7.
New York works for remote work but isn't optimized for it: internet 280 Mbps, income tax 17%, cost index 100.
Healthcare
- Healthcare quality index (weight 70%)70
- Healthcare out-of-pocket / month (lower = better) (weight 30%)450
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For New York: (70/100 × 0.7 + max(0, 1 − 450/500) × 0.3) × 10 = 5.2.
New York has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~450 USD/month. Cross-border insurance closes the gap.

Calculation
The corridor compares Seoul (anchor for South Korea) with New York (anchor for United States). Monthly basket costs are converted to KRW using the live FX rate, then differenced per category. Destination salary requirements use United States's effective tax rate and the Mundevo lifestyle multipliers.
Limitations
- Corridor uses a single anchor city per country; if your origin or destination is a smaller city, run the dedicated salary-needed page to refine.
- FX is a snapshot. Rates move 1–3% per month — use the live rate on the day of any transfer.
- Tax model is the effective rate for a single salaried filer; visa-specific regimes (e.g. Portugal NHR) can shift the net by 5–10 percentage points but are not modeled here.
- Relocation costs (shipping, deposits, agency fees) are estimated separately by the partners surfaced below and are not included in the monthly cost delta.
