Annual Summary
About
This calculator applies 2024 standard employee-side rates for Korea's four social insurance programs (국민연금 4.5%, 건강보험 3.545%, 장기요양 12.95% of health premium, 고용보험 0.9%) and approximates income tax using the NTS simplified withholding table (간이세액표), adjusted for the number of dependents and children under 20. It also shows the full deduction breakdown and annual summary so you can compare offers or plan a budget at a glance. Because every calculation happens client-side in JavaScript, your salary figures never leave your device.

FAQ
- Is the calculated net pay exact?
- No — it is an estimate. Insurance rates use 2024 standard figures, and income tax uses a simplified withholding table approximation (간이세액표 근사). Actual pay can differ due to company-specific allowances, year-end tax settlement (연말정산), and other personal factors. Consult a tax specialist or your HR department for precise figures.

- Does it work offline or without an internet connection?
- Yes. Once the page is loaded, all calculations run locally in your browser with no network required. It works on a plane, in a restricted network, or anywhere without Wi-Fi.
- Is my salary data sent to any server or stored in the cloud?
- No. All data stays in your browser. Your last inputs are saved in your browser's local storage purely for convenience — nothing is sent to any server.
- How does the income tax calculation work?
- Income tax is estimated using a bracket approximation of the NTS simplified withholding table (국세청 간이세액표). The base amount for one dependent is adjusted by subtracting 30,000 KRW per additional dependent and 12,500 KRW per child under 20. Local income tax is then 10% of the income tax amount.
