Real Purchasing Power (PPP-Adjusted)
The most honest comparison: take each net salary and adjust it for what it can actually buy in the local market. A dollar in Thailand buys more or less stuff than a dollar in South Korea — this table shows the equivalent local purchasing power.
True winner (after cost-of-living): Thailand
On average, 52.5% more real purchasing power across the salary levels compared. Note: this differs from the tax-only winner (South Korea) — once you account for local prices, the picture changes.

"Real value" = net pay in USD divided by the local cost-of-living + rent index (NYC = 100, scaled). Higher real value means more goods and services per dollar. Adjustment uses Numbeo 2026 indices.

Q.What does PPP-adjusted salary mean?
Purchasing Power Parity (PPP) adjustment translates a salary into the equivalent local buying power. For example, if you earn $80,000 after tax in Thailand and the cost of living in South Korea is different, your money "feels like" $121,471 when spent in South Korea. This is the most honest way to compare jobs in different countries.

Thailand uses 5 income tax brackets ranging from the lowest rate to the top marginal. South Korea uses 8 brackets. Both countries also levy social security contributions. Full bracket details are shown in the comparison table above.
Q.Does this include local/state taxes?
This comparison uses national/federal income tax plus social security contributions. Some countries (US, CA, CH, DE) have additional state, provincial, cantonal, or local income taxes that would increase total tax burden in high-tax sub-jurisdictions. Federal-only tax typically understates the true rate by 2–12 percentage points.
Q.Are currency conversion rates accurate?
We use approximate April 2026 exchange rates for USD base comparisons. Real-time FX varies day to day. The take-home percentage is currency-independent and is the most reliable cross-country metric.
Q.Where does the cost-of-living data come from?
Cost-of-living indices and sample monthly costs are sourced from Numbeo (2026), a crowd-sourced cost-of-living database. Purchasing power parity (PPP) rates are from OECD 2025 statistics where available. Numbeo data is user-contributed and reflects average urban prices; actual costs can vary by city, neighbourhood, and lifestyle. For personal financial decisions, always verify with up-to-date local sources.
