Tips

Simulate Salary Negotiations

Check how a ₩1M salary increase translates to actual take-home pay. The increase varies by tax bracket.

Best Practices

Factor in Tax-Exempt Allowances Before Negotiating

Meal allowances (up to ₩200,000/month) and commuting subsidies are not subject to income tax or social insurance contributions. When comparing two job offers, check whether these allowances are included — a lower gross salary with generous tax-exempt allowances can yield higher take-home pay than a nominally higher salary without them.

Recalculate After Major Life Changes

Getting married, having a child, or supporting elderly parents changes your number of dependents, which directly affects your simplified tax withholding rate. Update your dependent count in this calculator after any such event to get an accurate picture of your new monthly net pay, and notify your HR department to adjust withholding accordingly.

Compare Take-Home Pay Across Tax Brackets, Not Just Gross

A ₩5 million raise sounds impressive, but if it pushes you into a higher income tax bracket, the marginal increase in take-home pay may be smaller than expected. Use the calculator to model your current salary and the proposed salary side by side. This gives you concrete numbers for negotiation rather than relying on gut feeling about how much more you will actually receive.

FAQ

Is this the exact take-home amount?

This is an estimate based on simplified tax tables. Actual amounts may differ after year-end tax adjustment.

Can freelancers use this?

This calculator is for salaried employees. Freelancers subject to 3.3% withholding need a separate calculation.

How does the year-end tax adjustment affect my monthly take-home pay?

Monthly withholding uses simplified tax tables that approximate your annual tax liability. The year-end adjustment reconciles the actual tax owed based on your real deductions (medical expenses, education, donations, etc.) against what was withheld throughout the year. Most employees receive a refund, but those with significant additional income sources or fewer deductions than assumed may owe extra. This calculator shows the monthly estimate; your final annual liability will differ.

Are social insurance rates the same for all employees?

The contribution rates are standardized nationally (National Pension 4.5%, Health Insurance approximately 3.545%, Employment Insurance 0.9% for employees), but the actual amounts depend on your monthly remuneration. There are also caps — for example, National Pension contributions are capped at a monthly standard income of ₩5.9 million (2026 standard). If your salary exceeds these caps, your effective contribution rate as a percentage of gross pay is lower than the statutory rate.
