An hours-worked calculator for a single shift: start and end times, unpaid breaks, overtime and pay — distinct from a weekly time card or pay-period timesheet.
If the end time is earlier than the start time, the shift is treated as overnight (finishing the next day).
hours worked (this shift)
How to use this tool
Start and end times; an end time earlier than the start is treated as overnight.
Enter the unpaid break in minutes — paid breaks should not be entered here.
Optionally enter the rate to see gross pay for the shift.
Advanced options set the overtime threshold, multiplier and days per week.
Formula & worked example
A 09:00–17:30 shift with a 30-minute break is 8 hours worked. At $20/hour that is $160. A 09:00–19:00 shift with the same break is 9.5 hours: 8 regular + 1.5 overtime at 1.5× = $160 + $45 = $205.
Limitations — read this before you rely on it
This calculator covers one shift pattern repeated across the week; it is not a weekly roster or a pay-period timesheet, and it does not handle taxes, deductions, or paid leave.
Frequently asked questions
If the end time is earlier than the start time, 24 hours are added, so 22:00–06:00 counts as an 8-hour shift before breaks.
No — only unpaid breaks reduce hours worked. Paid breaks are already part of your paid time.
An overtime multiplier of 1.5: overtime hours are paid at 1.5 times the normal hourly rate.
No. This is a single-shift hours-worked calculator; a time card tracks a whole week's roster of different shifts.
No — the pay shown is gross pay before tax and deductions.
