How to use Korean Take-Home Pay Calculator
Enter your annual or monthly salary
If you choose annual, enter your annual salary and the number of months to divide it by. If your company pays bonuses on top and counts 13 months, enter 13. If you choose monthly, enter the total pre-deduction pay from your pay slip as it is. Either way, enter the pre-tax amount.
Enter your non-taxable pay
This is pay that is not taxed, such as a meal allowance. Enter the monthly amount your pay slip lists as non-taxable.
Enter your dependents and children
Dependents are the number of people, including yourself, who qualify for the basic deduction at year-end tax settlement. Children aged 8 to 20 count toward the number of dependents and are also entered in the children field. If you want to cross-check against your pay slip, choose the pay slip amount and enter it as it is.
Adjust the rates
The four social insurance rates change every year. If they differ from your pay slip, correct them right there.
What it’s good for
Income tax is looked up straight from the official withholding table
Employers withhold income tax every month using the Korean National Tax Service simplified withholding table for employment income (Income Tax Act Enforcement Decree, Appendix 2). This tool carries the table revised on February 27, 2026 (applied from March pay) as published. It looks up the tax from your monthly pay after non-taxable items and your number of dependents. If you have children aged 8 to 20, it deducts a further 20,830 KRW for one child, 45,830 KRW for two, and 33,330 KRW per child from the third on. You can also pick an 80%, 100% or 120% withholding rate. For example, an annual salary of 36,000,000 KRW with a 200,000 KRW meal allowance and one dependent (yourself) gives income tax of 56,800 KRW and local income tax of 5,680 KRW. You can also enter the income tax from your pay slip to cross-check.
Long-term care insurance is applied to the health insurance premium, not to your pay
This is where people most often go wrong. The long-term care premium is not your pay multiplied by a rate. Instead, take the health insurance premium you worked out first, multiply it by the long-term care rate divided by the health insurance rate (in 2026, 0.9448 / 7.19, about 13.14%), and round down to the nearest 10 KRW. If you skip that order, you end up a few thousand KRW off your pay slip. This tool follows that order and shows on screen which amount it was applied to.
Non-taxable pay still lands in your bank account
Non-taxable items such as meal allowances are left out when insurance premiums and taxes are calculated, but they are still paid to you as salary. So the more non-taxable pay you have, the lower your deductions and the higher your take-home pay. This tool shows the taxable amount and the pre-tax monthly pay separately so you can see that difference.

When the result isn’t what you expected
It differs from my pay slip by a few thousand KRW
Like the national insurance bills, this tool rounds all four insurances down to the nearest 10 KRW, and counts long-term care as the health insurance premium x 0.9448 / 7.19. If your company rounds in a different way, it can differ by a few tens of KRW. The standard monthly income used for the National Pension is usually set from the previous year's income, so it can differ from this year's pay.
Take-home pay shows as negative
This happens when the income tax you entered is larger than the monthly pre-tax pay. Check that you have not entered the annual income tax. This field takes the monthly income tax.
Income tax differs from my pay slip
Try matching the number of dependents, the number of children and the withholding rate (80% or 120%) to the form you submitted to your company. In a month when a bonus is paid, tax is worked out by dividing the bonus over the payment period, so it differs from a single row of the withholding table. Pay before February 2026 used the child deduction before the revision (12,500 KRW for one child).

Korean Take-Home Pay Calculator FAQ
Can I calculate from a monthly salary instead?
Yes. Choose the monthly option at the top and enter the total pay before deductions from your pay slip. The tool treats that amount as one month of pay and calculates the deductions and net pay. The annual take-home and annual salary figures are shown by multiplying by 12 months.
If I enter only my annual salary, will it show my take-home pay automatically?
Yes. Just set the number of dependents (including yourself) and the number of children aged 8 to 20, and the tool calculates income tax from the simplified withholding table. Keep in mind that the income tax withheld each month is an advance payment that is recalculated at year-end tax settlement with your deductions applied, and companies that spread bonuses across months may withhold differently from this result.
How is the take-home pay table built?
It uses the same engine as the calculator and lists annual salaries from 24,000,000 KRW to 100,000,000 KRW in steps of 1,000,000 or 5,000,000 KRW, showing monthly pre-tax pay, the four social insurances, taxes, monthly take-home and annual take-home. The non-taxable amount, dependents and rates you entered above are applied as they are, and you can sort by clicking a column heading.
The rates differ from what I actually pay
Rates change every year. You can edit them on screen, so please set them to the values shown on your bill or pay slip.
Is it accurate for high earners?
The National Pension is calculated within a standard monthly income range of 410,000 KRW (lower limit) to 6,590,000 KRW (upper limit) for July 2026 to June 2027. So even if your monthly pay is above 6,590,000 KRW, the National Pension does not rise beyond 313,020 KRW.
Does it calculate the employer's share too?
No. It is not deducted from your pay, so it is not included.
Can it tell me my year-end tax refund?
No. That needs the various deductions and spending records, so this tool does not cover it.
Are the values I enter saved?
No. They are not saved and disappear when you refresh.
