Time card calculator
Enter when you clocked in and out each day and how long your unpaid breaks were. You get your total hours for the week in hours and minutes and in decimal hours. Add your hourly rate to see your gross pay.
Hours and minutes vs decimal hours
Payroll multiplies your hourly rate by decimal hours, so 7 hours 45 minutes is 7.75 hours, not 7.45. At $18 an hour, that's 7.75 × $18 = $139.50. To convert, divide the minutes by 60.
| Minutes | Decimal hours | Minutes | Decimal hours |
|---|---|---|---|
| 5 | 0.08 | 35 | 0.58 |
| 10 | 0.17 | 40 | 0.67 |
| 15 | 0.25 | 45 | 0.75 |
| 20 | 0.33 | 50 | 0.83 |
| 25 | 0.42 | 55 | 0.92 |
| 30 | 0.50 |
How to fill in a time card
- Overnight shifts. If you clock out after midnight, enter the clock-out time as it is. A clock-out earlier than the clock-in counts as the next morning.
- Breaks. Enter only unpaid meal breaks, usually 30 minutes or more. Under federal rules, short breaks of 5 to 20 minutes are paid time, so don't subtract them.
- Overtime. The calculator pays 1.5× after 40 hours in the week, the federal rule. California, Alaska, Nevada and Colorado also have daily overtime: use the overtime calculator for those.
Time clock rounding
Many employers round punches to the nearest 5, 6 or 15 minutes. Under federal rules, rounding is allowed only if it evens out over time, so you're paid for all the time you actually work. A time card calculator with your exact punches shows whether rounding is costing you.
Questions
How many hours is 9 a.m. to 5:30 p.m. with a 30-minute lunch?
8 hours: 8 hours 30 minutes on the clock, minus the 30-minute unpaid lunch.
How do I write 8 hours 20 minutes in decimal?
20 ÷ 60 = 0.33, so 8 hours 20 minutes is 8.33 hours.
