What is Take-Home Pay Calculator?
The Take-Home Pay Calculator helps Korean workers determine their actual monthly and annual net salary after all mandatory deductions. In Korea, employees are required to contribute to four major social insurance programs and pay income tax, all of which are automatically deducted from the gross salary. The four social insurance contributions are: National Pension (4.5% of monthly salary), Health Insurance (3.545%), Long-term Care Insurance (12.95% of the health insurance premium), and Employment Insurance (0.9%). In addition, income tax is calculated using progressive tax brackets ranging from 6% to 45%, and local income tax is charged at 10% of the income tax amount. The number of dependents and children under 20 affects the income tax calculation through personal exemptions and child tax credits. This calculator provides a clear breakdown of every deduction item, showing you exactly where your money goes each month. Understanding the gap between gross salary and take-home pay is essential for accurate budgeting, negotiating salary offers, and financial planning. Whether you are entering the workforce, considering a job change, or simply want to verify your payslip, this tool gives you instant, accurate results.
How to Use
- Enter your annual salary (in 10,000 KRW units).
- Enter the number of dependents (including yourself).
- Enter the number of children under 20.
- Review the social insurance, tax deductions, and monthly net pay.
Tips & Best Practices
- When evaluating job offers, always compare net take-home pay rather than gross salary — two offers with the same gross can differ in net pay depending on tax deductions.
- Claim all eligible dependents to reduce your income tax burden. Each dependent reduces your taxable income through personal exemptions.
- Tax-exempt allowances like meal allowance (200,000 KRW/month) and commuting allowance can increase your take-home pay without raising your tax bracket.
- Review your year-end tax settlement carefully — many employees receive a tax refund by properly reporting medical expenses, education costs, and charitable donations.
- If your annual salary is near a tax bracket boundary, consider maximizing pre-tax deductions like retirement savings contributions to stay in a lower bracket.

FAQ
What are the 4 major social insurances in Korea?
The 4 major insurances are National Pension (4.5%), Health Insurance (3.545%), Long-term Care (12.95% of Health), and Employment Insurance (0.9%). Both employee and employer contribute.
How is income tax calculated?
Income tax uses progressive rates from 6% to 45% based on taxable income. Deductions vary based on the number of dependents and children.
How does annual salary relate to monthly take-home pay?
Monthly take-home pay is your annual salary divided by 12, minus social insurance premiums, income tax, and local income tax. Higher salaries have higher tax rates, reducing the take-home ratio.
What is local income tax in Korea?
Local income tax is a surtax equal to 10% of your income tax. It is paid to local governments and withheld from your salary along with the income tax.
Is my salary data stored?
No, all calculations are performed in your browser and no salary data is sent to or stored on any server.
How do tax-exempt allowances affect take-home pay?
Tax-exempt allowances such as meal allowance (200,000 KRW/month) are excluded from income tax calculations, increasing your take-home pay even at the same salary level.
Why does take-home pay not increase proportionally with a raise?
Korea uses progressive taxation, meaning higher income is taxed at higher rates. A raise may push part of your income into a higher bracket, and social insurance contributions also increase proportionally, resulting in a smaller net increase than expected.
Are the social insurance rates the same for all workers?
The percentage rates are standard for most employees. However, National Pension contributions are capped at a maximum monthly salary of 5.9 million won, and Health Insurance has its own cap. Very high earners may see a lower effective social insurance rate.
What happens to my National Pension contributions?
National Pension contributions are saved in your individual pension account. You will receive monthly pension payments upon retirement (currently at age 63, gradually increasing to 65). The amount depends on your contribution history and average earnings.
Does this calculator account for year-end tax adjustments?
This calculator shows the standard monthly withholding. Year-end tax settlement may result in a refund or additional payment based on actual deductions, medical expenses, education costs, and other factors claimed during the year.
How do dependents affect my tax calculation?
Each dependent reduces your taxable income through personal exemptions (1.5 million won per person). Children under 20 provide additional child tax credits. More dependents generally mean lower income tax and higher take-home pay.
Is the employer's contribution included in this calculation?
No, this calculator shows only the employee's share of deductions. Employers pay matching contributions for National Pension, Health Insurance, and Employment Insurance, plus additional amounts for industrial accident insurance.
