Enter the figures and press Calculate: the breakdown shows here, with the rules used.

Results are estimates for planning only, not legal, tax or payroll advice. Rates marked "estimate" are published figures Mihnaro has not confirmed; check them with the country’s tax authority, its social security body or your accountant, and your employment contract. Each rule shows its source.

Rules for United States and their sources

The version in force from 2026-01-01. "Verified" rules were checked against the official source named; the others are estimates to confirm.

Requires confirmation

These rules of United States are not applied, or are applied as estimates, because we could not confirm them from an official source yet. What is needed to add them:

  • End of service, Paid annual leave days (minimum), Hours in a work day, Salary days in a month: There is no federal gratuity or paid leave; state rules differ. Needed: State-by-state rules, if these calculators are to be offered.
