Know More: How the Time Card Calculator Works
How it works: enter a start time, end time and unpaid break for each day you worked. The calculator totals each day and the week in hours:minutes and decimal hours, splits regular and overtime hours under the rule you choose, and multiplies by your hourly rate for gross pay.

How to calculate hours worked
- Convert the start and end times to 24-hour time (1:30 PM = 13:30).
- Subtract the start time from the end time.
- Subtract unpaid breaks, such as a 30-minute lunch.
- Add up every day for the weekly total.
Hours worked = end time − start time − unpaid breaks
For example, 9:00 AM to 5:30 PM is 8 hours 30 minutes. Minus a 30-minute lunch, that is 8:00 hours. Five days like that make 40 hours.
For an overnight shift, the end time is the next day: 10:00 PM to 6:30 AM is 8 hours 30 minutes. The calculator handles this automatically when the end time is earlier than the start time.
Converting minutes to decimal hours (table)
Payroll systems use decimal hours, so 7 hours 45 minutes is 7.75 hours, not 7.45.
Decimal hours = hours + minutes ÷ 60
| Minutes | Decimal | Minutes | Decimal |
|---|---|---|---|
| 1 | 0.02 | 30 | 0.50 |
| 5 | 0.08 | 35 | 0.58 |
| 6 | 0.10 | 40 | 0.67 |
| 10 | 0.17 | 45 | 0.75 |
| 12 | 0.20 | 48 | 0.80 |
| 15 | 0.25 | 50 | 0.83 |
| 20 | 0.33 | 55 | 0.92 |
| 25 | 0.42 | 60 | 1.00 |
To go the other way, multiply the decimal part by 60: 7.5 hours is 7 hours and 0.5 × 60 = 30 minutes, or 7:30. At $20 an hour, 7 hours 45 minutes pays 7.75 × $20 = $155.
Unpaid breaks and lunch
Under federal rules, a meal period of 30 minutes or more when you are fully relieved of duty does not have to be paid, so subtract it from your hours. Short rest breaks of 5 to 20 minutes count as hours worked and must be paid, so do not subtract them (U.S. Department of Labor, Fact Sheet 22).
If you have to stay at your desk, answer phones or watch equipment during lunch, that time is work time. Some states, including California, Washington and Oregon, require meal and rest breaks of set lengths; your employer's policy may give you more.
Time rounding rules
Federal rules allow employers to round clock times to the nearest 5 minutes, tenth of an hour (6 minutes) or quarter hour (15 minutes), as long as rounding averages out and does not always favor the employer (29 CFR 785.48). With quarter-hour rounding, the common 7-minute rule applies:
- 1 to 7 minutes past the quarter hour rounds down: 8:07 becomes 8:00.
- 8 to 14 minutes past rounds up: 8:08 becomes 8:15.
Choose the same rounding as your employer in the calculator to match your paycheck. For example, clocking in at 8:53 and out at 5:08 is 8:15 exactly; with 15-minute rounding it becomes 9:00 to 5:15, which is 8:15 as well.
When overtime starts
Under the federal Fair Labor Standards Act, non-exempt employees earn 1.5 times their regular rate for hours over 40 in a workweek. Hours are not averaged over two weeks, so a 45-hour week and a 35-hour week earn 5 hours of overtime even though they add up to 80.
| Overtime rule | Overtime at 1.5x | Double time at 2x |
|---|---|---|
| Federal (most states) | Over 40 hours a week | None required |
| Daily overtime (e.g. Alaska, Nevada for lower-paid workers) | Over 8 hours a day or 40 a week | None required |
| California | Over 8 a day or 40 a week; first 8 hours on the 7th straight day | Over 12 a day; over 8 on the 7th straight day |
Hours already paid as daily overtime are not counted again toward the 40. Colorado also pays overtime after 12 hours in a day. For overtime pay with bonuses and taxes, see the Overtime Calculator.
Examples
| Shift | Unpaid break | Hours | Decimal |
|---|---|---|---|
| 9:00 AM to 5:30 PM | 30 min | 8:00 | 8.00 |
| 8:45 AM to 5:15 PM | 45 min | 7:45 | 7.75 |
| 7:00 AM to 3:30 PM | None | 8:30 | 8.50 |
| 10:00 PM to 6:30 AM (overnight) | 30 min | 8:00 | 8.00 |
| 6:00 AM to 8:00 PM | 30 min | 13:30 | 13.50 |
A full week: Monday to Thursday 9:00 AM to 5:30 PM and Friday 9:00 AM to 6:30 PM, each with a 30-minute lunch, is 41 hours: 40 regular and 1 overtime. At $20 an hour that is $800 + $30 = $830 gross pay.
California long day: a 13.5-hour Monday counts as 8 regular hours, 4 hours at 1.5x and 1.5 hours at 2x.

Time Card Calculator FAQs
How do I calculate hours worked?
Subtract your start time from your end time, then subtract unpaid breaks. For 9:00 AM to 5:30 PM with a 30-minute lunch: 8 hours 30 minutes minus 30 minutes is 8 hours. Add each day together for your weekly total, and convert minutes to decimals for payroll.
How do I convert minutes to decimals for payroll?
Divide the minutes by 60. 15 minutes is 0.25, 30 minutes is 0.5 and 45 minutes is 0.75, so 7 hours 45 minutes is 7.75 hours. Multiply decimal hours by your hourly rate to get your pay.
Is lunch counted as hours worked?
Not if it is a real meal break of 30 minutes or more and you are completely relieved of duty. Short breaks of 5 to 20 minutes must be paid. If you work through lunch, such as answering calls, that time counts as hours worked.
What is 7.5 hours in hours and minutes?
7.5 hours is 7 hours and 30 minutes, because 0.5 of an hour times 60 is 30 minutes. Likewise 7.25 hours is 7:15 and 7.75 hours is 7:45.
How many hours is 9 to 5?
9:00 AM to 5:00 PM is 8 hours. With an unpaid 30-minute lunch, it is 7.5 hours worked, or 37.5 hours over a five-day week. With a 1-hour unpaid lunch it is 7 hours a day.
