Why compare?
Two Korean salaries with the same headline can produce different take-home depending on non-taxable allowances, dependents, and child credits. Korea uses progressive tax (6–45%), and social-insurance contributions have caps and floors, so take-home increases are not linear. This calculator applies the same conditions to both offers so you see the pure salary effect.
Frequently asked questions
- How much extra take-home from a 10M KRW raise?
- Going 50M → 60M typically adds about 700–750K KRW/month (8.4–9M/year). The progressive bracket determines the exact amount, so it is rarely a clean 1:1 with the raise size.
- What if non-taxable benefits differ between offers?
- This calculator applies the same non-taxable to both offers. If they differ, run each through the salary-takehome calculator separately and compare. Confirm caps for meal allowance, vehicle, child education, etc.
- Is the 5-year cumulative meaningful?
- Yes — a 10M/year gap compounds to ~50M over 5 years. Real comparisons should also consider raises, promotions, and pension impact. This calculator assumes 0% raises for both.
- How do I include performance bonuses?
- Don't roll variable bonuses into salary. Use this calculator for the stable base, then evaluate bonuses separately at a conservative expected value (e.g., 50% probability).
Reference only. Compares two salaries under identical conditions (dependents, children, non-taxable). Differences in non-taxable benefits per company, bonus volatility, annual raises, severance accumulation, and employer-side social insurance benefits are not modeled.
