Weekly Work Hours / Timesheet Calculator
This weekly work hours calculator adds up the time you put in across the whole week. Enter the hours you worked on each day — Monday through Sunday — and it instantly gives you the weekly total. Add an hourly rate and it also works out how much you earned for the week. It works like a simple timesheet: fill in the days, read the total, and copy your pay figure. Handy for hourly employees checking a payslip, freelancers billing by the week, and anyone tracking overtime.

Total pay
Enter each day in decimal hours (for example 7.5 for 7 h 30 min). The total adds up the seven days and, if you enter a rate, works out the pay for the week.

How it works
Enter each day in decimal hours — for example 8 for a full day or 7.5 for seven and a half hours. The calculator adds the seven daily values together to give the weekly total, updating live as you type. If you enter an hourly rate, it multiplies the total hours by the rate to give your total pay for the week; leave the rate at zero and it just shows the hours. Because it uses decimal hours (8 h 30 min = 8.5) the totals add and multiply cleanly, without the errors that come from adding hours and minutes separately.
From weekly to monthly and yearly hours
To convert hours per week into hours per month, multiply by 4.33 (the average number of weeks in a month: 52 weeks ÷ 12 months); to get hours per year, multiply by 52. So a 40-hour week works out to roughly 173 hours a month and 2,080 hours a year. These are the figures typically used in contracts and when turning an hourly rate into a monthly salary.
| Hours/week | Hours/month (×4.33) | Hours/year (×52) |
|---|---|---|
| 20 | 86.6 | 1,040 |
| 30 | 129.9 | 1,560 |
| 35 | 151.6 | 1,820 |
| 40 | 173.2 | 2,080 |
| 48 | 207.8 | 2,496 |
Maximum legal working week in different countries
The maximum weekly working time varies by country and is usually set by law or collective agreement. The values below are indicative: they exclude overtime, special regimes and differences by sector or agreement, and the rules change over time. In 2025 Spain lowered its reference week and Mexico is debating a gradual move from 48 to 40 hours.
| Country | Reference working week |
|---|---|
| Spain | 40 h (reduction proposed) |
| Mexico | 48 h (moving toward 40 h) |
| France | 35 h |
| Germany | ≈40 h (48 h legal max) |
| Italy | 40 h (48 h max with overtime) |

Preguntas frecuentes
- How do I enter hours for each day?
- Enter each day in decimal hours rather than hours and minutes. A full eight-hour day is just 8, seven and a half hours is 7.5, and six hours and fifteen minutes is 6.25. Days you did not work stay at 0. The calculator adds the seven values as you type.
- How is the weekly total calculated?
- The weekly total is simply the sum of the seven daily figures — Monday through Sunday. For example, 8 hours each day from Monday to Friday with nothing on the weekend gives 40 hours. There is no rounding: the total reflects exactly what you enter.
- How is my total pay worked out?
- Total pay is the weekly total of hours multiplied by the hourly rate you enter. So 40 hours at a rate of 20 gives 800. The rate is optional — leave it at zero and the pay figure stays hidden, showing you just the hours.
- Can I use it for overtime?
- Yes. Enter your actual hours for each day, including any extra time, and the weekly total will include the overtime. If your overtime is paid at a different rate, calculate the standard and overtime portions separately and add the two pay figures together.
- What if I convert minutes wrong?
- To turn minutes into decimal hours, divide the minutes by 60. So 15 minutes is 0.25, 30 minutes is 0.5, and 45 minutes is 0.75. Adding hours and minutes as if minutes were out of 100 is the most common timesheet mistake — decimal hours avoid it.
