Multiply your daily work hours by the number of days you work per week. The result is your total weekly hours. From there, monthly and yearly totals follow directly.
Formula: Total weekly hours = Hours per day × Days per week
For example, working 8 hours a day for 5 days gives 40 hours per week — the standard full-time schedule in most countries. Working 7.5 hours a day for 4 days gives 30 hours per week, a common compressed or part-time arrangement.
| Hours/day | Days/week | Weekly | Monthly | Yearly |
|---|---|---|---|---|
| 8 | 5 | 40 h | 173 h | 2,080 h |
| 7.5 | 5 | 37.5 h | 163 h | 1,950 h |
| 8 | 4 | 32 h | 139 h | 1,664 h |
| 6 | 5 | 30 h | 130 h | 1,560 h |
| 4 | 5 | 20 h | 87 h | 1,040 h |
The standard full-time threshold varies by country. In the United States the traditional expectation is 40 hours per week. In Germany and the Netherlands, full-time is typically 36–40 hours. In France, the legal working week is 35 hours. In Japan, the Labour Standards Act sets the limit at 40 hours per week.
If you work beyond the standard hours, add your extra daily hours to the daily total before multiplying. For example, 8 regular hours plus 1.5 hours of overtime on 3 days per week: (8 × 5) + (1.5 × 3) = 44.5 hours per week. Many jurisdictions require overtime pay at 1.5× for hours beyond 40 per week.
Multiply your daily work hours by the number of days you work each week. If you work 7 hours a day for 5 days, your total is 35 hours per week.
In most countries, full-time is 35–40 hours per week. The US standard is 40 hours. France uses 35 hours as the legal maximum. Part-time is generally anything below 30–35 hours per week.
A standard 40-hour week across 52 weeks gives 2,080 hours per year. After subtracting typical paid leave — 10 public holidays and 2 weeks vacation — actual working time is approximately 1,880 hours.
Multiply your weekly hours by 4.333 (52 weeks divided by 12 months). For a 40-hour week: 40 × 4.333 = approximately 173 hours per month.
No. Enter your net working hours per day, excluding breaks. If your day is 8 hours including a 30-minute break, enter 7.5.
