Overtime calculator

Enter the total hours you worked in a week, your regular-hours threshold, your hourly rate, and your overtime multiplier. The calculator will split time and pay into regular and overtime values.

Calculator

Split regular time and overtime pay

You can enter worked time as decimal hours like 45.5 or in HH:MM format like 45:30.

Daily vs weekly overtime

This tool works from total hours for the period you enter. It is useful when you already know the final worked total and want to split that time into regular and overtime hours, but it does not apply day-by-day overtime rules on its own.

Example: 45.5 total hours at a 40-hour threshold and 1.5x multiplier gives 5.5 overtime hours. Example: 52 total hours at a 40-hour threshold and 2x multiplier gives 12 overtime hours. If you need per-day logic first, total those daily entries on the weekly calculator or timecard calculator before using this page.

How to calculate overtime hours with this calculator

  1. Enter your total worked time for the week in decimal hours or HH:MM format.
  2. Enter the regular-hours threshold used for overtime.
  3. Add your hourly rate and overtime multiplier if you want a pay estimate.
  4. Click Calculate overtime.
  5. Review regular time, overtime time, overtime pay, and total pay.

Example of calculating overtime hours

Example: Enter 45:30 total hours, a 40-hour threshold, a $20 hourly rate, and a 1.5 multiplier.

This overtime calculator returns 40h 00m regular time, 5h 30m overtime, $165.00 in overtime pay, and $965.00 in total pay.

How this overtime hours calculation works

The calculator converts the total worked time and threshold into minutes so it can compare them directly. Any break subtraction should already be reflected in the total you enter here, because this page focuses on overtime rather than daily shift math. It then separates regular and overtime minutes, converts them into readable hours, and uses decimal hours to estimate pay and overtime hours.

Common calculation scenarios

  • Weekly work hours that go over a 40-hour threshold.
  • Timesheet hours entered as 45:30 instead of decimal format.
  • Overtime hours paid at 1.5x the regular rate.
  • Payroll checks when you already know the total hours worked.

Why accurate overtime tracking matters

Incorrect overtime hours can lead to payroll mistakes, missed pay, or confusion when reviewing total work hours. A clear overtime calculator helps you compare regular hours and payroll hours before the final employee timesheet is approved.

Next step

Use this when the totals are ready. Use software when overtime review keeps repeating.

This page does its job well when you already know the total hours and only need the regular-versus-overtime split. If overtime has to be reviewed every week across multiple people, locations, or projects, software comparisons make more sense because the bottleneck is no longer the math itself.

FAQ

Overtime calculator questions

These answers explain how the overtime tool interprets inputs and how it connects to the rest of the work hours site.

Can I use 45:30 instead of 45.5 hours?

Yes. The calculator accepts both decimal hours and HH:MM input so you can use the format you already have in your timesheet or payroll record. That makes overtime hours calculation easier when different systems show work hours in different ways.

What multiplier should I enter?

Many payroll rules use 1.5x, but some agreements or contracts use different overtime rates. Enter the multiplier that matches your policy so the calculator can estimate overtime pay and overtime hours correctly.

Does this page calculate daily overtime?

This page is focused on total overtime based on the total worked time you enter for the period. For day-by-day work hours or a more detailed timesheet, use Weekly or Timecard before you calculate overtime hours.

Can I leave pay fields at zero?

Yes. If you only care about overtime time and regular work hours, leave the hourly rate at zero and the calculator will still show the split. This is useful when you only need a time result for a timesheet review or to calculate hours worked without pay.
