How to Calculate Total Work Hours

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.

What Counts as Full-Time?

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.

Overtime Calculation

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.
