Timesheet Hours Calculator

The calculator uses a single daily hours figure across all workdays. To model a shorter Friday, compute a weighted average across all days. For example, working 8 hours Monday through Thursday and 4 hours on Friday gives an average of 7.2 hours per day across 5 days.

A calendar month averages 4.333 weeks (52 weeks ÷ 12 months). Using exactly 4 would under-count monthly hours by about 8 percent. The 4.333 multiplier keeps the monthly total consistent with the annual total: weekly hours × 4.333 × 12 equals weekly hours × 52.

Yes, for payroll accuracy. Regular and overtime hours often attract different rates or carry different legal obligations. Keeping them separate makes it straightforward to apply multipliers, audit pay slips, and comply with labour regulations that cap weekly overtime.

Teetrack lets you log hours directly against projects and clients. Once your daily entries are recorded, the built-in reports aggregate totals by week, month, or custom period — matching exactly what this calculator estimates. Sign up, create a project, and start logging.

No. The annual total assumes all 52 weeks are worked. To reflect actual working time, reduce workdays per week proportionally, or treat the result as a gross figure and subtract holiday hours manually. Most full-time employees take 10 to 25 days off per year, lowering the annual total by 80 to 200 hours.
