Timesheet Calculator
Time card calculator
A time card is just a week of clock-in and clock-out times. Enter them below, subtract lunch, and get hours, overtime, and optional gross pay. You can also download a CSV.
From a paper time card to decimal hours
Say a card shows Monday 08:00–16:30, 30-minute lunch; Tuesday the same; and Saturday 09:00–13:00 with no lunch.
- Each of the five weekdays: 8:30 elapsed − 0:30 lunch = 8.00 hours
- Saturday: 4.00 hours
- Week total: 5 × 8.00 + 4.00 = 44.00 hours
- With a 40-hour weekly cutoff: 40 regular + 4 overtime
- At $22 an hour and 1.5× overtime: (40 × 22) + (4 × 33) = $880 + $132 = $1,012.00
Split shifts on a time card
A split shift of 7:00–11:00 and 15:00–19:30 is 4:00 + 4:30 = 8:30, or 8.50 decimal hours. Add both rows for that day, with the lunch already handled by the gap, or enter one row and the unpaid minutes if you never clocked out.
Overnight rows
If the card says 22:00 in and 06:30 out, that is 8.50 hours, not a negative time. Type the next-morning out time and the calculator carries the shift through midnight.

Questions people ask
How does a time card calculator work?
You enter each day's start and end times and any unpaid lunch. The calculator subtracts the break, adds the week in hours and minutes and in decimal hours, and can split overtime and estimate gross pay.
How do I total clock-in and clock-out times for the week?
Enter each clock-in as the start and each clock-out as the end for that day. If you clock out and back in for a split shift, use a second row. The card adds every day for the week.
Can I calculate a biweekly time card?
Calculate each workweek separately, then add the two weekly totals. Keep overtime on the week it was earned rather than averaging the two weeks.
