Formulas

The math behind this calculator, written out so you can verify the result.

Annual work hours

Annual hours = Weekly hours × (52 − Paid weeks off − Unpaid weeks off)

This multiplies your typical weekly hours by the number of working weeks in a year, after subtracting all time off.

Example:

Input: 40 hours/week, 2 paid weeks, 0 unpaid weeks

Calculation: 40 × (52 − 2 − 0) = 40 × 50

Result: 2000 hours
