How to use Job Change Net Salary Compare
Compares current and offered Korean salaries under the same conditions to show how much monthly take-home pay really changes.
Both salaries use the 2026 social insurance rates and the withholding table, revealing how much of a raise goes to tax and contributions.
- Enter the current and offered gross annual salaries; buttons such as +5 million adjust the offer quickly.
- Set the non-taxable monthly pay and dependents that apply to both jobs.
- Review the monthly and annual difference and the share of the raise that reaches take-home pay.
Useful for
- Checking the real effect of a job offer before negotiating
- Working backwards from a desired take-home increase to a salary request
Limits and checks
- Progressive tax brackets make take-home growth smaller than the gross raise percentage.
- Note bonuses, benefits and commuting costs separately because they are not in the salary figure.
Worked example
Moving from 40 million to 45 million
Current salary: 40,000,000 Offered salary: 45,000,000 Monthly non-taxable pay: 200,000 Dependents: 1
Both salaries exclude severance and are split over 12 months.
Monthly take-home comparison
Current take-home: 2,935,813 After moving: 3,259,730 Difference: +323,917 a month (+3,887,004 a year)
About 77.7% of the 5 million gross raise reaches take-home pay.
Common issues
Take-home growth is lower than the raise
Insurance rises with pay and income tax is progressive, so this is expected. Check the higher tax and contributions in the comparison table.
One offer includes severance in the salary
Salaries including severance should be divided by 13. Use the 13-month option in the take-home pay calculator separately.
How to interpret the result
Use the monthly table to compare the gross difference with added tax and contributions.

FAQ
How much more per month from KRW 40 million to 45 million?
With 200,000 non-taxable pay and one dependent, take-home pay rises from 2,935,813 to 3,259,730, about 324,000 a month or 3.89 million a year.
Why doesn't the whole raise reach take-home pay?
Pension, health and employment insurance grow with pay, and withholding tax grows faster as income moves up the table.
Do dependents change the comparison?
More dependents lower withholding tax and raise take-home pay. The same dependents are applied to both jobs.
