Overtime multiplier

Daily hours are calculated as end time - start time - break. Weekly hours are daily hours multiplied by work days.

Monthly pay uses a 52-week year divided by 12 months.

Overtime laws and paid break rules vary. Use your local rules and employer policy for official payroll calculations.

This tool is best for quick planning and timesheet estimates.

How are work hours calculated?

The calculator subtracts start time from end time, subtracts breaks, and multiplies by the number of work days.

Does it support overnight shifts?

Yes. If the end time is earlier than the start time, it treats the end time as the next day.

How is overtime estimated?

Weekly hours above the overtime threshold are multiplied by the overtime rate you enter.

Is this payroll advice?

No. Payroll rules vary by location, employer policy and contract. Use this as a planning estimate.
