Take-home Salary Calculator
See your real monthly take-home pay after the four insurances and income tax are deducted from your salary.
Insurances use the employee share; income tax is an annual approximation. Confirm with your payslip.
What is deducted?
From monthly pay we subtract the employee share of national pension (4.5%), health insurance (3.545%) plus long-term care, and employment insurance (0.9%), then income tax and local income tax (10% of income tax). The remainder is your take-home pay. Income tax is approximated on an annual basis.
When to use it
- Job offers: compare the real take-home of different salary offers.
- Budgeting: plan fixed spending and savings from the amount that actually lands.
- Non-taxable input: add meal allowance and see how deductions and take-home change.
Things to note
- Insurance rates and tax tables change yearly, and actual deductions vary by company, dependents, and non-taxable items.
- Income tax is an annual approximation, not the official monthly withholding table, so it may differ from your payslip.
- Confirm exact figures against your payslip or the tax service.

Why does it differ slightly from my payslip?
Income tax uses the official monthly simplified withholding table, while this calculator approximates on an annual basis. Companies also differ on non-taxable items and dependents, so results can differ by a small amount. Use it as a reference.
What goes in the non-taxable amount?
Non-taxable pay such as a meal allowance (up to 200,000 won/month), commuting support, or childcare allowance. The default is a typical 200,000 won meal allowance; adjust to your contract.
How do I count dependents?
Include yourself plus qualifying spouse, children, and parents who meet the deduction requirements. More dependents lower income tax and slightly raise take-home pay.
Is my salary data stored?
No. All calculation happens only in your browser and your salary and family details are never sent to or stored on a server.
