How to calculate a split shift
Calculate each work block separately, subtract any unpaid break inside that block, and add the two results. The time between blocks is outside both work spans, so it is already excluded.
Total = (first clock-out − first clock-in − first unpaid break) + (second clock-out − second clock-in − second unpaid break).
Example: a lunch service and an evening service
| Block | Clock times | Unpaid break inside block | Net time |
|---|---|---|---|
| First | 8:00 AM–12:00 PM | 0 minutes | 4h |
| Second | 4:00 PM–8:00 PM | 15 minutes | 3h 45m |
| Total | Two work blocks | 15 minutes | 7h 45m / 7.75 hours |
The span from the first start to the final finish is 12 hours, but the entered work time after the unpaid break is 7h 45m. Do not deduct the four-hour gap a second time.
Can a split shift cross midnight?
Yes. If a block ends earlier on the clock than it starts, the calculator moves that end time to the following day. If the second block starts after midnight, choose its actual next-day start date. Overlapping blocks produce an error instead of double-counting hours.
What if the blocks have different hourly rates?
Multiply each block’s unrounded hours by its own rate, then add the amounts. For 4 hours at $20 and 3h 45m at $24, the basic gross estimate is $80 + $90 = $170. Use the full work-hours calculator to enter separate rates or more than two blocks.
Does this calculate split-shift premiums or legal pay?
No. This tool adds the work durations you enter. It does not decide whether a gap is compensable, apply split-shift premiums, or determine wages owed. Keep the actual timestamps and compare your record with the applicable agreement and official pay statement.
