Where the Full-time Equivalent Calculator fits
Convert part-time and full-time hours into full-time equivalent staff. The main figure it returns is the Total FTE, worked out from the values you enter.
It belongs with the other hr & workforce tools. If you are comparing options or checking a result from another angle, try the HR Software ROI Calculator, Billable Hours Calculator or the Remote vs. On-Location Workers Calculator.
How to use the Full-time Equivalent (FTE) Calculator
- Enter your numbers. Start with Full-time employees, Part-time employees, Average part-time hours per week, then fill in Full-time hours per week. Use real figures from your own records where you can. Fields marked optional can stay at zero.
- Read the result. The highlighted box gives the Total FTE, and the cards below show Part-time FTE, Headcount. Tables and charts break it down further.
- Test other scenarios. Results update as you type. Change one value at a time to see what drives the answer, and press Reset to go back to the defaults.
Formula and how it works
Example with real numbers
Here is the Full-time Equivalent (FTE) Calculator using the default values shown in the calculator above:
Inputs
| Full-time employees | 20 |
|---|---|
| Part-time employees | 12 |
| Average part-time hours per week | 20 |
| Full-time hours per week | 40 |
Results
| Total FTE | 26 |
|---|---|
| Part-time FTE | 6 |
| Headcount | 32 |
With these inputs the calculator returns Total FTE: 26. Change any value in the calculator to see how the result moves.
What if you change one input?
Sensitivity check: raising Full-time employees from 20 to 24 (about 20% higher) and leaving everything else as in the example above changes the results like this:
| Result | Example | After the change | Change |
|---|---|---|---|
| Total FTE | 26 | 30 | +15.4% |
| Part-time FTE | 6 | 6 | 0% |
| Headcount | 32 | 36 | +12.5% |
The input that moves the result most is the one to check twice. Change it in the calculator above to test your own case.
