Overtime is counted per workweek, as the FLSA requires. Rates are before taxes.

How to use it

  1. Fill in start and end times for each workday. The defaults are a 9-to-5:30 day with a 30-minute lunch.
  2. Change the break minutes if your lunch is shorter, longer or paid.
  3. Enter your hourly rate to turn the hours into regular and overtime pay.

The formula

Daily hours = end − start − unpaid break

Weekly hours = sum of the five days

Overtime hours = weekly hours − 40 (if positive)

Example: Monday to Thursday 8:00–17:00 with a 1-hour lunch is 8 hours a day. Friday 8:00–12:00 with no break is 4 hours. The week is 36 hours (36.00 decimal), all at the regular rate.

Good to know

  • Working a weekend day too? Use the 7-day timesheet calculator so overtime is counted correctly.
  • If you clock out and back in for lunch, the time card calculator with lunch takes four punches a day.
  • A standard full-time week is 40 hours; many employers count 32 to 36 hours or more as full-time for benefits.
