Hours Worked Calculator
Clock-in and clock-out times, minus a break, straight into both hours worked and pay owed — the exact calculation behind an hourly paycheck, done in one step instead of separate subtraction and multiplication.

How the hours worked calculator works
Total minutes worked = (clock-out time − clock-in time) in minutes, minus the specified break duration.
Pay = hours worked × hourly rate, where hours worked is minutes worked ÷ 60.
Worked example: 08:30 to 17:00, 45-minute break, rate 25 per hour
- Raw span: 08:30 to 17:00 = 510 minutes.
- Minus the 45-minute break: 510 − 45 = 465 minutes = 7.75 hours.
- Pay = 7.75 × 25 = 193.75.
Common mistakes to avoid
Forgetting to subtract an unpaid break before calculating pay
An 8.5-hour clock-in-to-clock-out span with a 30-minute unpaid lunch actually represents 8 hours of paid work, not 8.5 — omitting the break subtraction directly overstates pay owed.
Entering clock times in 12-hour format without converting to 24-hour
Like the Time Duration Calculator, this expects 24-hour format — a shift ending at '5:00' meant as 5 PM needs to be entered as '17:00', or the calculation will interpret it as 5 AM instead, producing a negative or nonsensical result.
Frequently asked questions
What happens if the break time exceeds the total clock-in-to-clock-out span?
The calculator floors the result at zero hours worked rather than showing a negative number, since a break can't reasonably exceed the total time on shift in a sensible scenario.
Does this handle an overnight shift that crosses midnight?
This calculator is built around a straightforward clock-in-to-clock-out same-day calculation; a shift crossing midnight would need the same wraparound handling used in the Time Duration Calculator to compute correctly.
How would I calculate pay including overtime rates?
This tool applies one flat hourly rate to all hours worked — for overtime calculations where hours beyond a threshold pay at a higher rate, the standard and overtime hours would need to be calculated and combined separately.
Why show pay per shift rather than assuming a fixed weekly schedule?
Actual hours (and therefore pay) vary day to day for many jobs — calculating per shift based on the real clock-in and clock-out times gives an accurate figure rather than assuming an idealised fixed schedule.
