Hours Worked Calculator

By ToolsHub360 Team · Last updated: October 2026

Find paid time between two clock punches, subtract an unpaid break, and optionally estimate gross pay.

Total paid hours

8:00

Decimal hours: 8.00 hours
Hours and minutes: 8:00 (hh:mm)

An earlier clock-out time is treated as the next day. Matching times mean zero hours. Unpaid breaks cannot make paid time negative.

How the calculation works

Worked minutes = elapsed minutes from clock-in to clock-out − unpaid break minutes; decimal hours = worked minutes ÷ 60; gross pay = decimal hours × hourly rate.

Worked example

Clock in at 9:00 AM and out at 5:30 PM. The shift lasts 8 hours 30 minutes. Subtract a 30-minute unpaid break to get 8:00 worked, or 8.00 decimal hours. At $20 an hour, estimated gross pay is $160 before taxes. If you instead leave at 5:15 PM, the paid result is 7:45, which is 7.75 decimal hours and $155.

From clock punches to paid hours

Begin with the actual start and end times recorded on your time clock. The elapsed time between them includes any break, so subtract only the minutes that were unpaid. A paid rest break should remain in the worked total. The calculator shows both a familiar hours-and-minutes value and a decimal value suitable for multiplying by a wage rate.

If your out time falls earlier than your in time, the tool treats it as the following day. For example, 10:00 PM to 6:00 AM is eight hours across midnight. An identical start and end time is treated as zero hours, not a 24-hour shift; this simple tool covers one shift shorter than a day. Divide longer work periods into separate entries.

Enter an optional hourly rate to see estimated gross pay for the shift. Leaving the rate blank keeps the time calculation but does not assume a wage. Gross pay is before taxes and deductions, and a single shift may have overtime or premium rules that this basic multiplication does not apply. Use the overtime or shift differential calculator to examine those separately.

Decimal hours are not clock minutes

Payroll often uses decimal hours rather than an hh:mm display. Sixty minutes equal one hour, so divide the minutes portion by 60: 15 minutes is 0.25 hour, 30 minutes is 0.50, and 45 minutes is 0.75. A result of 7:45 is 7.75 hours, not 7.45. Multiplying 7.45 by your rate would undercount fifteen minutes of paid work.

The display rounds decimal hours to two places for readability. The gross-pay calculation uses the unrounded minutes before formatting the dollar result, which avoids some avoidable rounding drift. If you add several shifts, add their underlying minutes first and round the weekly total only after the sum. The weekly timesheet tool is intended for exactly that task.

For a 9:00 AM to 5:15 PM shift with a 30-minute break, elapsed time is 495 minutes and paid time is 465 minutes. That is 7 hours and 45 minutes. Dividing 465 by 60 gives 7.75 decimal hours. At $20 per hour the gross result is $155. This check makes it easier to spot an incorrect punch or break entry.

Breaks, rounding, and your pay stub

Whether a break is paid depends on the applicable rules and the employer's policy, not on this calculator. Only enter an unpaid break duration. If you work through an unpaid break, correct the timesheet with your employer rather than quietly deducting time you actually worked. Keep your own record of punch times and compare it with the approved time record.

Some employers apply a lawful, consistently used time-rounding policy. This tool does not round punches to an interval: it uses the exact times entered and subtracts the break minutes you specify. Your pay stub may differ if your employer rounds under applicable law, uses a different pay period, or pays a premium rate for some hours. Ask payroll how its system handles rounding when you reconcile a discrepancy.

A gross-pay estimate is not your deposit. Payroll may withhold income tax, Social Security, Medicare, insurance, and retirement contributions. Save the shift total, then compare your weekly time and gross pay with the timesheet and paycheck calculators. This tool helps audit arithmetic, but your employer's records and local wage rules determine the actual payment.

Frequently Asked Questions

How do I convert minutes to decimal hours?

Divide the minutes by 60 and add whole hours. For example, 7 hours 45 minutes is 7 + 45/60 = 7.75 decimal hours.

How are overnight shifts calculated?

When the clock-out time is earlier than clock-in, the calculator treats clock-out as occurring on the next day. A matching pair of times produces zero hours.

Are breaks deducted from hours?

Enter the minutes of unpaid breaks only. Paid breaks remain part of paid hours; rules vary by workplace and location.

What are time-rounding rules?

Some payroll systems round punches under applicable rules. This tool uses your exact entered times without rounding; check your employer's policy for your pay stub.
