How the hours are worked out
Each day is clock-out minus clock-in, plus 24 hours if the shift crosses midnight, minus the unpaid break. The week is the sum of the days. Decimal hours are minutes divided by 60, which is why 8 hours 30 minutes shows as 8.50 and not 8.30. Rounding, if you switch it on, is applied to each day's worked time before the week is totalled, which is how most time clocks do it.
Minutes to decimal, the part everyone looks up
| Minutes | 5 | 10 | 15 | 20 | 25 | 30 | 35 | 40 | 45 | 50 | 55 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| Decimal | 0.08 | 0.17 | 0.25 | 0.33 | 0.42 | 0.50 | 0.58 | 0.67 | 0.75 | 0.83 | 0.92 |

Overtime in one example
The sample week above is 8.50, 8.50, 10.00, 8.50 and 8.00 hours after breaks: 43:30 in total. Federally that is 40.00 regular hours and 3.50 hours of overtime at time and a half. In California, Monday, Tuesday, Wednesday and Thursday each pass 8 hours and trigger daily overtime, and the week's straight time then stays at 40.00, so the total comes out the same — 3.50 hours of overtime either way; a week of four 10-hour days would not match, since federal law owes nothing there and California owes 8 hours at 1.5×.
Questions
How do I calculate hours worked from clock-in and clock-out times?
Subtract the clock-in time from the clock-out time, then subtract any unpaid break. 8:00 AM to 5:00 PM is 9 hours; take off a 30-minute lunch and it is 8 hours 30 minutes, which payroll writes as 8.50. If the clock-out is earlier than the clock-in, the shift crossed midnight and 24 hours are added first: 10:00 PM to 6:00 AM is 8 hours.
How do I convert hours and minutes to decimal hours?
Divide the minutes by 60. 7 hours 45 minutes is 7 + 45 ÷ 60 = 7.75. 15 minutes is 0.25, 20 minutes is 0.33, 30 minutes is 0.50, 40 minutes is 0.67. The calculator shows both forms; switch the display with the dropdown, and the decimal hours page has the full minute-by-minute chart.
What is the 7-minute rule?
Federal regulation (29 CFR 785.48) lets employers round punches to the nearest quarter hour as long as it averages out: 1 to 7 minutes past the quarter round down, 8 to 14 round up. A 9:07 punch becomes 9:00, 9:08 becomes 9:15. Rounding has to work in both directions over time; it cannot only ever favour the employer. Pick 'nearest 15 min' above to see the rounded totals.
Should I enter short rest breaks as unpaid?
No. Under federal rules (29 CFR 785.18) rest breaks of roughly 5 to 20 minutes are paid working time and should not be deducted. Only a bona fide meal period, usually 30 minutes or more and free of duties, is unpaid. Put the meal period in the break box and leave short breaks out.
When is overtime owed?
Under federal law (the FLSA), for hours over 40 in a workweek, at one and a half times the regular rate, for non-exempt employees. California adds daily overtime: over 8 hours in a day at 1.5×, over 12 at 2×, and on a seventh consecutive workday the first 8 hours at 1.5× and beyond at 2×. A few other states (Alaska, Nevada, Colorado) have daily rules; the calculator offers federal and California.
Is the pay figure my paycheck?
No, it is gross pay: hours times rate, plus overtime premiums. Taxes, benefits and other deductions come off after. It is the number to check against the 'gross' line on your stub.
