Work Hours Calculator

Calculate paid shift time from clock-in, clock-out and unpaid break minutes, including overnight shifts and decimal-hour conversion. Calculate it clearly with Figur.

Subtract unpaid breaks from a single shift

Convert each clock time to minutes after midnight and subtract clock-in from clock-out. If the result is negative, add 1,440 minutes to treat clock-out as the next day. Subtract the unpaid break, then divide paid minutes by 60 for decimal hours. For hours and minutes, use whole hours plus the remainder. A 30-minute fraction is 0.5 hours, not 0.30 hours.

Method and assumptions

Shift minutes = clock-out − clock-in, plus 1,440 only when negative. Paid minutes = shift minutes − unpaid break; decimal hours = paid minutes ÷ 60.

  • This represents one shift under 24 hours, without dates or time zones. Equal start and end times mean zero hours, not a full day.
  • Break minutes are whole minutes; a break longer than the shift is rejected.
  • Paid breaks should not be entered as unpaid time. Payroll rounding, overtime premiums and daylight-saving changes are not modeled.

Personal work and pay estimate, not an official timecard, payroll calculation or determination of employment rights. Your employer's policies and applicable rules control.

Worked example

Clock in at 22:00, clock out at 06:30 the next day, with a 30-minute unpaid break.

(390 − 1,320 + 1,440) − 30 = 480 paid minutes. 480 ÷ 60 = 8 hours.

Frequently asked questions

How does an overnight shift work?

22:00 to 06:30 is 510 minutes after adding one day. With a 30-minute unpaid break it is 480 paid minutes, or 8 hours.

Can I enter a 24-hour or multi-day shift?

No. There are no date inputs. Identical clock times mean zero, so use separate shifts for longer periods.

Is this an official payroll total?

No. It is elapsed paid time before employer rounding, overtime rules or payroll policies.
