Net Salary Calculator
Works out take-home pay from a gross salary after the four insurances, income tax and local tax.
The gap between a contracted salary and what arrives in the account is the four insurances plus income tax plus 지방소득세, and each of those has its own base and its own ceiling. This works through them in order and shows every line, so the result is arguable rather than asserted.
Calculated on the 2026 rates.
2026년 기준 · 국민연금 9.5% · 건강보험 7.19% · 장기요양 건강보험료의 13.14% (보수월액의 약 0.945%) · 고용보험 0.9% · 최저임금 10,320원
Income tax here is the annual settlement divided by twelve, not the 간이세액표 (simplified withholding table). That table is an approximation used for withholding and is trued up at 연말정산 each February, so this figure is closer to the real annual burden and a few per cent from what a payslip shows.
The employer-side contributions (고용안정·직업능력개발, 산재보험) vary with headcount and industry, so an average is used here. Your actual invoice will differ.
Rates change every year. If this still reads 2026 after 2026 has passed, the figures are out of date.
Salary
A meal allowance is non-taxable up to 200,000 a month. Almost every payslip has one, and leaving it out overstates the deductions.
Under 8 there is no credit; it is covered by 아동수당 (child benefit) instead.
Set the rates by hand — when they differ from your payslip
The employee pays half of these. Rates change every year and the invoice can arrive before this calculator is updated, so if your payslip disagrees, match it here.

The 연말정산 items — medical, education, donations, housing, pension savings — are not modelled. They only ever reduce tax, so the figures here are the most conservative end.

The employer pays the same amount again for 국민연금, 건강보험 and 장기요양, and then 고용안정·직업능력개발 and 산재보험 on top. None of it appears on a payslip.
How to use it
Enter the gross figure
Annual or monthly. What matters is that it is the 세전 total including any fixed allowances, since that is the base the contributions are charged on.
Enter the 비과세 allowances
A meal allowance, a vehicle allowance, childcare — these reduce both the tax base and the insurance base, and almost every Korean payslip has at least the first. Leaving them out overstates the deductions noticeably, which is why they are an input rather than an assumption.
Set the number of dependants
인적공제 changes the income tax substantially. The result is the annual settlement divided by twelve, not a lookup in the 근로소득 간이세액표.
Compare against a real payslip
A few per cent of difference either way is expected and explained below. A larger gap usually means an allowance or a dependant that was not entered here.
Common questions
Where do the rates come from?
From one dated table shared by every calculator here: 국민연금·건강보험·장기요양·고용보험 rates for the current contribution year with their issuing authority, the 기준소득월액 ceiling that 국민연금공단 revises each July, and the 소득세법 §55 (Income Tax Act, art. 55) brackets unchanged since the 2023 amendment. The year and the rates are printed on the page, and a test fails once the pension ceiling passes its stated expiry.
Why does it differ from my payslip?
Because a payslip withholds by the 근로소득 간이세액표, a deliberately approximate lookup grid the 국세청 publishes, which is trued up at 연말정산 each February. This computes the annual settlement and divides by twelve, so it is closer to what is finally owed and a few per cent from what is withheld monthly.
What is not modelled?
Everything itemised at 연말정산 — 의료비, 교육비, 기부금, 주택자금, 연금저축 — and the employer-side rates that vary by headcount and industry (고용안정·직업능력개발, 산재보험). Those deductions only ever reduce tax, so the figure here is the pessimistic end.
Can I use this figure in a contract?
No. It is an estimate, not a filing or a payroll calculation, and the deductions it leaves to you are the ones that move the number most. Agree the gross figure and let payroll compute the net.
