What does this Full-Time Equivalent (FTE) calculator measure?

This calculator determines how many full-time employees your total workforce hours represent over a specific period. It converts combined part-time and variable hours into a standardized full-time equivalent number. For example, if 640 total hours are worked over 4 weeks at 40 hours per week full-time, that equals 4 FTEs.

When should I use the FTE calculator?

Use this calculator when you need to understand staffing levels in terms of full-time equivalents rather than headcount. It is especially useful for budgeting, workforce planning, compliance reporting, and benefit eligibility analysis. It helps compare part-time and full-time staffing on a consistent basis.

How do I calculate FTE using monthly part-time hours?

Enter the total hours worked by all employees during the month, the standard full-time weekly hours, and the number of weeks in the month. The calculator divides total hours by (full-time hours per week × number of weeks). For example, 640 total hours divided by (40 × 4) equals 4 FTEs.

Does this calculator count part-time and full-time employees together?

Yes, it combines all hours worked—whether from part-time, full-time, or temporary staff—into a single FTE value. It does not count individual employees but instead measures total labor hours relative to a full-time schedule. This provides a more accurate view of actual workforce capacity.

What should I enter for "Number of Weeks in Period" for a monthly calculation?

For most monthly estimates, you can use 4 weeks as a standard approximation. If you want greater accuracy, you may use 4.33 weeks to reflect the average number of weeks per month. Choose the value that best aligns with your reporting or payroll cycle.

Why is my FTE lower than my total number of employees?

FTE reflects total hours worked, not headcount. If several employees work part-time schedules, their combined hours may equal fewer full-time equivalents. For example, eight employees working 20 hours per week equal 4 FTEs, not 8.
