How to Use

Useful as a guide when changing jobs or receiving a raise.
About the Formula
Social insurance is estimated based on standard monthly remuneration using association health insurance rates. Income tax is calculated by applying progressive rates to taxable income after employment income deduction, basic deduction, and dependent deduction. Resident tax is estimated at a flat 10%. Actual amounts may differ due to bonuses and local tax rate variations.
