When HR tells you your net pay, are you curious about your actual gross compensation? This tool uses China's current progressive individual income tax (IIT) brackets to accurately reverse-calculate your gross salary and tax payable based on your net salary and total social security and housing provident fund contributions. The total social security and housing fund refers to the sum of mandatory personal deductions, including pension (8%), medical insurance (2%), unemployment insurance (0.5%), and housing provident fund (5-12%).
Can the year-end bonus be calculated together?
No. This tool only calculates monthly salary. Year-end bonuses are taxed separately and require a dedicated calculator.
Why does my calculation result differ from my payslip?
There could be three reasons: 1) Your city has additional local deduction policies; 2) You are claiming special additional deductions (e.g., children's education); 3) Your company uses the cumulative annual withholding method.
The calculation results do not include non-mandatory deductions such as supplementary housing funds or enterprise annuities. If cities like Beijing, Shanghai, Guangzhou, or Shenzhen implement special local social security and housing fund rates, you will need to manually adjust the input values. Fresh graduates hired after 2023 should note that the standard deduction may be eligible for additional pre-tax deductions.
Typical example: An employee in Shanghai has a net salary of 15,000 RMB and monthly social security/housing fund contributions of 3,200 RMB (including a 12% housing fund). The reverse calculation result would be a gross salary of 18,500 RMB and a tax payable of 1,300 RMB. We recommend HR professionals use this tool during salary negotiations to simultaneously explain the statutory contribution structure of the "Five Insurances and One Fund" to candidates.
