How payroll hours are calculated

Payroll hours are the paid hours an employee worked in a pay period. The standard formula is (End time − Start time) − Unpaid breaks. The result is converted to decimal hours by dividing total minutes by 60, then multiplied by an hourly rate to estimate gross pay. Hours over the weekly threshold (typically 40 in the U.S.) are paid at a premium overtime rate.

Why decimal hours matter for payroll

Payroll software multiplies hours by an hourly rate. Working in base-60 (hours and minutes) leads to arithmetic mistakes. Decimal hours like 8.25 for 8 hours 15 minutes keep the math accurate and consistent across timesheets, invoices, and pay stubs.
