Work Hours Calculator
Add up clock-in and clock-out times across the week to get total hours worked — and estimated pay.
How this calculator works
- Enter a start time and end time for each day you worked, plus any unpaid break minutes.
- The calculator computes hours worked per day, handling overnight shifts that cross midnight.
- It totals hours for the week and, if you enter an hourly rate, estimates gross pay.
This calculator turns a week of clock-in and clock-out times into total hours worked, subtracting any unpaid breaks. Add your hourly rate to also see estimated gross pay for the week — handy for double-checking a timesheet or estimating a paycheck before it arrives.
Example
Working 9:00 AM–5:30 PM with a 30-minute unpaid break is 8 hours. Across five such days, that's 40 hours for the week — at $22/hour, about $880 in estimated gross pay.
Limitations
This calculates gross hours and pay only, with no overtime rules applied — use the Overtime Calculator separately if part of the week is paid at a higher rate.
Frequently asked questions
How do I calculate hours worked from clock-in and clock-out times?
Subtract the start time from the end time, then subtract any unpaid break time. This calculator does that for each day and totals the week.
Does this handle overnight shifts?
Yes — if your end time is earlier than your start time, the calculator assumes the shift crossed midnight and adds 24 hours before computing the duration.
Can I calculate pay as well as hours?
Yes — enter an hourly rate and the calculator multiplies it by total weekly hours for an estimated gross pay figure.
Does this apply overtime rates automatically?
No — it treats all hours the same. Use the Overtime Calculator if some hours should be paid at a higher rate.
