Methodology
How the calculators work, and where the numbers come from
Principles
- The law first. Each formula follows the article of the labour, social insurance or tax law it implements, cited on the calculator page.
- One source of truth. Every rate, cap and band lives in a single data file. When an authority publishes a change, one edit updates every calculator and page.
- Show the working. Every result is broken down line by line so you can check it against a payslip or a settlement.
- Private by design. Calculations run in your browser. Nothing you type is sent anywhere.
Conventions
- Service length counts calendar days from start date to last working day inclusive, minus unpaid leave, divided by 365.25 so leap years don't distort whole years. Partial years count pro rata.
- Daily wage is monthly wage ÷ 30 unless the law sets another divisor. Kuwait's law uses 26 working days.
- Gross-to-net calculators assume a resident employee paid monthly, with no other income, benefits in kind or special exemptions.
- Rounding is to two decimals for display only. Payroll systems may round each line differently, so small differences are normal.
