📌 Key facts
- Under the federal Fair Labor Standards Act, non-exempt employees earn at least 1.5 times their regular rate for hours over 40 in a workweek.
- To convert minutes to decimal hours, divide by 60: 7:45 is 7.75 hours.
- A shift that crosses midnight is calculated by adding 24 hours to the end time.
- A timesheet is added day by day before totaling the week.
- A 30 minute unpaid meal break comes off the gross time before you total hours.
How the weekly total is calculated
For each day, hours worked equal the time between start and end, minus the break. If the end is earlier than the start, the shift crosses midnight. The weekly total is the sum of the seven days.
\[ \text{daily hours} = (\text{end} - \text{start} ,\ + 24 \, \text{h} \ \text{if negative}) - \text{break} \,;\, \text{total} = \text{sum of the days} \]
A row with no start or end counts as zero, so leave days off empty.
Overtime under federal law
The Fair Labor Standards Act (FLSA) requires overtime pay at 1.5 times the regular rate for non-exempt employees for hours worked beyond 40 in a workweek.
| Hours in the week | Pay rate |
|---|---|
| 0 to 40 | regular rate |
| over 40 | 1.5 × regular rate |
Some states, such as California, also require overtime after 8 hours in a day, and double time in some cases. Salaried exempt employees are not covered. This tool applies the weekly rule only.
Minutes to decimal hours
Payroll uses decimal hours: minutes ÷ 60.
| Week total | Decimal |
|---|---|
| 40:00 | 40.00 |
| 37:30 | 37.50 |
| 39:45 | 39.75 |
| 41:20 | 41.33 |
Time card calculator: fill in your weekly hours
For a reliable time card calculator result, fill in the sheet day by day. First, enter the start and end times. Then subtract the lunch break. Next, move to the next day. Finally, the tool adds the week and flags hours above the threshold.
For example, you work 9 AM to 5:30 PM with a 30 minute unpaid break, Monday to Friday. Each day is 8 hours, so the week is 40 hours. So with a 40 hour threshold, you have no overtime. But if you add one 2 hour shift on Saturday, that is 2 hours of overtime.
Time card calculator: overtime and pay
A time card calculator also helps you check your pay. Under federal law, non-exempt employees earn time and a half after 40 hours in a workweek. Some states add a daily rule, so check your state. Also, exempt salaried employees usually do not earn overtime.
| Hours in the week | Pay rate |
|---|---|
| Up to 40 | Regular rate |
| Over 40 | 1.5 times the regular rate |
For example, at $20 an hour and 45 hours, you earn $800 for the first 40 hours plus $150 for 5 overtime hours, which totals $950. For more detail, open the overtime calculator.
Time card calculator: tips to avoid errors
A few habits prevent errors. First, log hours the same day. Second, keep the minutes and do not round too early. Third, convert to decimal hours only at the end. That way, you limit drift.
Also, for a single shift, the hours calculator is more direct. Finally, to turn an hourly rate into a salary, use the hourly to salary calculator.
Time card calculator: a typical week
For a reference point, here is a typical week. Monday through Thursday, you work 9 AM to 5:30 PM with a 30 minute break, which is 8 hours a day. On Friday, you finish at 4:30 PM, which is 7 hours. So the weekly total is 39 hours. With a 40 hour threshold, you have no overtime yet.
Also, keep your time card each month. In fact, it helps if you disagree with your pay stub. For example, you can quickly find the day you stayed later than planned. Then you can bring that exact record to your manager. Finally, a clear record keeps the talk short and friendly, and it protects both sides if a question comes up months later.
3 real-life examples
Five days from 9:00 AM to 5:00 PM with a 30-minute lunch
Each day is 8 hours minus 0.5 hour = 7.5 hours. The week is 37 hr 30 min (37.5 decimal hours) with no overtime.
A long week at $20 an hour
With 45 hours: \( 40 \times \$20 = \$800 \) plus \( 5 \times \$20 \times 1.5 = \$150 \). Estimated gross pay: $950.
A night shift
Starting 10:00 PM and ending 6:30 AM with a 30-minute break gives 8 hr 00 min. The calculator crosses midnight on its own.
