Overview

The Salary Comparison Calculator places two annual salaries side by side and compares their net take-home pay after deducting social insurance premiums, income tax, and local income tax. It helps with job-change decisions and salary negotiations.

Formula

Monthly Net Pay Difference = Salary B Net Pay − Salary A Net Pay

For each salary:
• Monthly Net Pay = (Annual Salary ÷ 12) − Social Insurance − Income Tax − Local Income Tax
• Annual Net Pay = Monthly Net Pay × 12
• Net Pay Ratio = Annual Net Pay ÷ Annual Salary × 100%

How to Use

1. 1Enter your current annual salary (Salary A).
2. 2Enter the comparison annual salary (Salary B).
3. 3Set dependents and non-taxable items for each.
4. 4Click 'Calculate' to see a side-by-side comparison table of net pay.

Tips

• ✔Higher salaries face progressive tax rates, so the net pay ratio decreases as salary increases.
• ✔Different non-taxable allowances (meal, vehicle) can cause different net pay for the same gross salary.
• ✔When changing jobs, compare benefits, pension type, and bonus structure alongside salary.
