Take-Home Pay Calculator

What this tool does

A Korea-based calculator: enter a gross annual salary, the monthly tax-free meal allowance included in it, and the number of dependants (1 to 5, including yourself) to see expected monthly take-home pay, the annual total, and an itemized list of what goes to national pension, health insurance, long-term care insurance, employment insurance, income tax and local income tax under Korean rules. Use it to turn a job offer into a monthly figure or to sanity-check the deductions on a Korean payslip. Default rates are for 2026 and can be changed under 'change the rate basis'.

How it is calculated

The monthly gross (annual ÷ 12) minus the tax-free meal allowance (capped at 200,000 won a month) is the base for both social insurance and tax. The employee shares are then applied: national pension 4.75% (half of the 9.5% rate for 2026; the income base is held between a floor of 400,000 and a cap of 6.37 million won), health insurance 3.595% (half of 7.19% for 2026), long-term care at 12.95% of the health premium (the 2025 ratio), and employment insurance 0.9%. Income tax is not looked up in the simplified withholding table; a full year is computed instead. From the taxable salary, the earned income deduction (capped at 20 million won), a year of insurance premiums and the personal deduction (1.5 million won per person) are subtracted to get the tax base, the basic rates (6% to 45%, eight brackets) are applied, the earned income tax credit is subtracted, and the result is divided by 12. Local income tax is 10% of income tax. For example, 50 million won with a 200,000 won meal allowance and 1 dependant gives a monthly gross of 4,166,667 won minus pension 188,417, health 142,602, long-term care 18,467, employment 35,700, income tax 206,847 and local tax 20,685, for take-home of about 3,553,949 won. With 3 dependants it is about 3,595,199 won; with no meal allowance about 3,506,383 won. Everything is calculated in your browser.

• Base pay: salary ÷ 12 − meal allowance (up to 200,000 won a month)
• National pension: base pay (held between 0.4 and 6.37 million won) × 4.75%
• Health insurance: base pay × 3.595%; long-term care is the health premium × 12.95%
• Employment insurance: base pay × 0.9%
• Earned income deduction: progressive 70%, 40%, 15%, 5% and 2% by bracket, at most 20 million won
• Income tax: (taxable salary − earned income deduction − annual premiums − 1.5 million won × dependants) × basic rate − earned income tax credit, divided by 12
• Earned income tax credit: 55% of computed tax up to 1.3 million won and 30% above; the limit is 740,000 won up to 33 million won of salary, 660,000 to 740,000 up to 70 million, 500,000 to 660,000 up to 120 million, and 200,000 to 500,000 above that
• Local income tax: income tax × 10%

Things to know

• The default rates come from different reference dates: pension 4.75% and health 3.595% are 2026 values, long-term care 12.95% is the 2025 ratio, and the pension cap and floor (6.37 million and 400,000 won) apply from July 2025 to June 2026. Check the latest notices from the National Pension Service and the National Health Insurance Service and enter them under 'change the rate basis'.
• Only 200,000 won a month of meal allowance is tax-free, so a larger figure is capped. Other tax-free allowances (car upkeep, childcare) have no field and are treated as taxable.
• Korean employers withhold monthly using the simplified withholding table and settle at year end. This tool divides a full-year estimate, so it can differ from monthly withholding by tens of thousands of won.
• Dependants include yourself: 1 if single, 3 with a spouse and one child. Five or more is counted as 5.
• Above 6.37 million won of taxable monthly pay, the pension stays at 302,575 won a month (6.37 million × 4.75%).
• Year-end items such as child tax credits or card, insurance and medical deductions are not included. With children, real tax is lower.
• Bonuses concentrated in one month raise that month's withholding, so monthly amounts can differ from this estimate.
