FTE Hours Calculator
Use this tool to convert worked hours into full-time equivalent (FTE). Default assumes a 40-hour full-time week.
Optional: sum individual employee hours
Enter each employee's weekly hours, then click “Use Sum as Total”.
What is an FTE hours calculator?
An FTE hours calculator helps you convert scheduled or worked hours into a standard unit called full-time equivalent. Instead of just counting people, FTE lets you measure staffing capacity. For example, two employees working 20 hours each are equal to 1.0 FTE when full-time is 40 hours per week.
This is useful for hiring plans, budgeting, forecasting labor costs, and understanding if your team is overstaffed or understaffed during busy periods.
FTE formula
The most common weekly formula is:
- FTE = Total weekly hours worked ÷ Full-time weekly hours
Example:
- Total hours worked = 120
- Full-time standard = 40 hours
- FTE = 120 ÷ 40 = 3.0 FTE
How to use this calculator
Method 1: Direct total hours
- Enter your full-time weekly standard (usually 35, 37.5, or 40).
- Enter total weekly hours for your department or project.
- Click Calculate FTE.
Method 2: Individual employee hours
- Add rows for each employee.
- Enter hours per person.
- Click Use Sum as Total, then calculate.
Why FTE is better than headcount alone
Headcount tells you how many people you employ, but not how much work capacity you actually have. If many team members are part-time, headcount can overstate available labor. FTE fixes that by normalizing everyone to the same baseline.
- Budgeting: Forecast wages and staffing costs accurately.
- Planning: Set realistic workload capacity by department.
- Compliance: Some regulations and benefits thresholds are tied to FTE.
- Operations: Compare teams with different shift patterns fairly.
Common FTE hour conversions
Assuming a 40-hour workweek:
- 20 hours/week = 0.50 FTE
- 30 hours/week = 0.75 FTE
- 40 hours/week = 1.00 FTE
- 60 hours/week = 1.50 FTE
- 80 hours/week = 2.00 FTE
If your organization uses 37.5 hours as full-time, the results will be different. Always use your own internal standard.
Practical examples
Example 1: Retail team coverage
A store has one manager working 40 hours, three associates working 25 hours each, and two weekend workers at 12 hours each. Total weekly hours = 40 + 75 + 24 = 139. With a 40-hour standard, staffing is 3.48 FTE.
Example 2: Project staffing model
A project requires about 200 labor hours each week. If full-time is 40 hours, you need 5.0 FTE. That could be 5 full-time staff, or a mix like 3 full-time plus 4 part-time employees at 20 hours each.
Common mistakes to avoid
- Mixing weekly and monthly hours in the same calculation.
- Using overtime as permanent staffing capacity.
- Forgetting PTO, holidays, or training time in workforce planning.
- Comparing departments with different full-time standards.
FAQ
Is 1 person always 1 FTE?
No. A person is 1.0 FTE only if they work your full-time standard hours.
Can FTE be above 1.0?
Yes. If total hours exceed full-time baseline, FTE can be 1.2, 2.7, 10.4, and so on.
Do I include contractors?
For internal planning, many teams include contractor hours to estimate true labor capacity. For reporting, follow your finance or HR policy.
Final takeaway
An FTE hours calculator gives a clearer view of workforce capacity than headcount alone. Use it weekly to keep staffing, budgets, and scheduling aligned—especially when your team includes a mix of full-time and part-time workers.
