Method
Taxable pay is gross pay minus pre-tax deductions. Taxes are estimated from user-entered income and payroll/social tax rates. Post-tax deductions are subtracted after tax.
Example
If gross pay is 3,500, pre-tax deductions are 200, income tax is 18%, payroll/social tax is 7.65% and post-tax deductions are 50, taxable pay is 3,300 and estimated net pay is about 2,403.55 for the period.
Common mistakes
Use rates that match your pay period and jurisdiction. Do not mix annual deductions with per-period pay unless you first convert them to the same period.
Limitations
This is not payroll, tax or legal advice. It excludes bracket systems, local credits, benefit caps, employer withholding rules and country-specific payroll definitions unless you enter equivalent rates manually.
