Time Card Calculator
This time card calculator adds up a week of clock-in and clock-out times. Enter a start time, an end time and an unpaid break for each day you worked. You get the total in hours and minutes and in decimal hours, split into regular hours and overtime over 40. Add your hourly rate to see gross pay before taxes.

How to fill in your time card
- For each day, enter when you started and when you finished. Leave both blank for a day off.
- Enter the unpaid break in minutes, such as a 30-minute lunch. Enter 0 if your breaks are paid.
- If a shift ends after midnight, just enter the real end time (for example 10:00 PM to 6:30 AM). An end time earlier than the start is counted as finishing the next day.
- Optionally enter your hourly rate. Regular pay, overtime pay and gross pay appear only when a rate is filled in.
- Keep the overtime box checked to pay hours over 40 at 1.5 times the rate, or uncheck it to see straight-time totals.
How the hours and pay are calculated
- Hours per day = end − start − break. Overnight shifts add 24 hours to the end time.
- Total = the sum of all days, shown as hours and minutes and as decimal hours (minutes ÷ 60).
- Overtime = total hours over 40 in the week. The rest are regular hours.
- Gross pay = regular hours × rate + overtime hours × rate × 1.5.
The 40-hour threshold and the time-and-a-half rate follow the federal Fair Labor Standards Act (FLSA). The Department of Labor says covered nonexempt workers must get at least 1.5 times their regular rate for hours worked over 40 in a workweek. A workweek is a fixed, recurring period of 168 hours, and hours can't be averaged over two or more weeks. The seven rows are one workweek.
Overtime is counted by the week only, so a long day is not overtime on its own. State daily overtime rules, such as California's, are not modeled. Check your state labor department if you work in a state with its own overtime law.
Worked examples
1. A standard five-day week
Monday to Friday, 8:00 AM to 5:00 PM with a 30-minute lunch, is 8.5 hours a day. The week totals 42 h 30 min (42.50 hours): 40 regular hours and 2.50 overtime hours. At $20 an hour that is $800 regular pay plus $75 overtime pay, so $875 gross. Without overtime the same hours would pay $850. If you add a Saturday from 9:00 AM to 1:00 PM with no break, the week grows to 46.50 hours, with 6.50 hours of overtime and $995 gross.
2. Twelve-hour shifts
Shifts from 7:00 AM to 7:00 PM with a 30-minute break count 11.5 hours each.
| Shifts | Total hours | Overtime | Gross at $25/h |
|---|---|---|---|
| 3 | 34.50 | 0.00 | $862.50 |
| 4 | 46.00 | 6.00 | $1,225.00 |
Three long days stay under 40 hours, so none of it is overtime. The fourth shift pushes the week to 46 hours: $1,000 regular plus $225 overtime.
3. Night shifts
Four shifts from 10:00 PM to 6:30 AM with a 30-minute break are 8 hours each. Each row is marked as overnight, and the week totals 32 hours, or $640 at $20 an hour.
Before you rely on the total
Only real meal breaks belong in the break field. According to DOL Fact Sheet #22, short rest periods (usually 20 minutes or less) must be counted as hours worked. Bona fide meal periods (typically 30 minutes or more) generally don't need to be paid, but only if you are completely relieved from duty. If you have to keep working while you eat, such as answering calls, you are not completely relieved, so enter 0 for that day.
Frequently asked questions
How do I convert minutes to decimal hours?
Divide the minutes by 60. 15 minutes is 0.25 hours, 30 minutes is 0.50 and 45 minutes is 0.75. For example, 8:50 AM to 3:05 PM with a 30-minute break is 5 h 45 min, which the calculator shows as 5.75 hours.
Does working on Saturday or Sunday mean overtime?
Not under federal law by itself. DOL Fact Sheet #23 says the FLSA doesn't require overtime pay for work on Saturdays, Sundays, holidays or regular days of rest, as such. Weekend hours count toward the 40-hour total like any other hours.
My workweek doesn't start on Monday. Does that matter?
The workweek doesn't have to match the calendar week. The rows are labeled Monday to Sunday, but you can fill them with any seven consecutive days of your employer's workweek. Don't spread one workweek across two calculations, because overtime is counted per workweek.
Can my employer round my clock-in times?
The DOL's regulations (29 CFR 785.48) accept, for enforcement purposes, rounding to the nearest 5 minutes, tenth of an hour or quarter hour, as long as it doesn't, over time, result in failing to pay employees for all the time they actually worked. This calculator uses your exact minutes and doesn't round.
Does everyone get overtime after 40 hours?
No. Some employees are exempt from FLSA overtime, and this calculator doesn't decide whether you are. It also uses your base rate only: bonuses or shift differentials can raise the regular rate used for overtime. For questions about your pay, contact the DOL Wage and Hour Division or your state labor department.
Is the pay shown my take-home pay?
No. It's gross pay before taxes and deductions. To turn an hourly wage into a yearly figure, try the hourly salary calculator, or the overtime calculator for different multipliers.
