Net Salary Calculator (Korea) — Take-Home Pay After Insurance and Tax (2026)
Jun 21, 2026
The thing you most want to know in a salary negotiation is "so how much actually lands in my account each month?" An annual salary is a pre-tax figure, so once Korea's four major insurances and income tax come out, your real monthly take-home pay shrinks quite a bit. This guide covers how to calculate your take-home pay accurately from your annual salary.
Enter your annual salary and your monthly take-home pay after insurance and tax deductions appears right away.
Net salary calculator →What comes out of your salary — the deductions
- National Pension — 4.5% of taxable income (employee's share).
- Health Insurance — about 3.5% of monthly remuneration + long-term care insurance (a set proportion of the health-insurance premium).
- Employment Insurance — around 0.9%.
- Income tax and local income tax — based on the simplified tax table, and they vary by number of dependents.
How to calculate — 1 step
- Enter your annual salary (or monthly pay) and number of dependents into the net salary calculator, and it instantly computes your monthly take-home pay along with the deduction breakdown.
For the same salary, more dependents lower income tax, which raises take-home pay.
When to use it
- Comparing what you actually pocket during a job change or salary negotiation.
- Checking that the deductions on your pay slip are correct.
- Setting a budget based on take-home pay for loans and living expenses.
