This FTE calculator converts every worker type into a single full-time equivalent number. Enter baseline weekly hours, annual weeks, and counts for full-time, part-time, contractor, and seasonal staff. You’ll see total FTE, total headcount, annual hours, and average hours per person. Optional revenue and labor cost fields add revenue per FTE, labor cost per FTE, and labor cost ratio. Use it for budgeting, headcount planning, and compliance reporting.
Staffing plans often mix full-time employees with part-time staff, contractors, and seasonal help. Comparing those groups by headcount alone hides how much work each group actually represents. The full-time equivalent (FTE) calculator solves that by expressing every worker category in the same unit: one FTE equals one person working the baseline weekly hours for the full year.
Set the baseline at 40 hours per week, enter your counts and average weekly hours, and the tool returns total FTE, headcount, annual hours, and the FTE ratio. Finance teams use it for labor cost planning. HR teams use it for ACA and benefits reporting. Operations teams use it to size shifts.
The optional financial section adds revenue per FTE and labor cost per FTE so you can see productivity and cost efficiency in the same view.
Choose your currency from the dropdown.
Set the full-time baseline hours per week and weeks worked per year.
Enter the number of full-time employees and their average weekly hours.
Add part-time employees and their average weekly hours.
Enter contractors or freelancers and their average weekly hours.
Add seasonal or temporary workers and their average weekly hours.
Optionally, enter annual revenue and annual labor cost.
Read total FTE, headcount, annual hours, and financial metrics from the result panel.
The FTE formula converts each worker category into a share of one full-time person. A worker who logs the baseline weekly hours counts as 1.0 FTE. Someone at half the baseline counts as 0.5 FTE.
Formula: FTE per category = Count × (Hours per Week ÷ Baseline Hours per Week)
Total FTE = Full-time FTE + Part-time FTE + Contractor FTE + Seasonal FTE
FTE Ratio = (Total FTE ÷ Total Headcount) × 100
Annual hours per category = Count × Hours per Week × Weeks per Year
Average annual hours per person = Total annual hours ÷ Total headcount
The baseline default is 40 hours per week across 52 weeks, which equals 2,080 annual hours. Change the baseline if your organization defines full-time differently. The tool clamps baseline hours to a minimum of 1, weeks to 1 through 52, and worker hours to 0 through 168 per week. If total headcount is zero, the result panel prompts you to enter data. If total FTE is zero while headcount is positive, it flags that all worker categories have zero weekly hours. If FTE ratio climbs above 100%, the tool warns you to verify entries, since that means average hours exceed the baseline.
Suppose a regional services company uses a 38-hour full-time baseline and operates 50 weeks per year. It has 23 full-time employees at 38 hours, 11 part-time employees at 21 hours, 4 contractors at 29 hours, and 7 seasonal workers averaging 16 hours across the year.
Full-time FTE: 23 × (38 ÷ 38) = 23.00.
Part-time FTE: 11 × (21 ÷ 38) = 6.08.
Contractor FTE: 4 × (29 ÷ 38) = 3.05.
Seasonal FTE: 7 × (16 ÷ 38) = 2.95.
Total FTE: 23.00 + 6.08 + 3.05 + 2.95 = 35.08 FTE.
Total headcount: 23 + 11 + 4 + 7 = 45 people.
FTE ratio: (35.08 ÷ 45) × 100 = 77.95%.
Annual hours: full-time 43,700; part-time 11,550; contractors 5,800; seasonal 5,600. Total 66,650 hours. Average per person is 1,481 hours.
The calculator places this in the “Mostly full-time” band. If annual revenue is $4,860,000 and labor cost is $2,310,000, revenue per FTE is about $138,544, labor cost per FTE is about $65,851, and the labor cost ratio is 47.5%.
FTE is a unit that expresses a worker’s hours as a share of a full-time schedule. One FTE equals one person working the baseline weekly hours for the full year. A 20-hour employee under a 40-hour baseline is 0.5 FTE. It lets you compare mixed worker types using one number.
Multiply the number of workers in a category by their weekly hours, then divide by the full-time baseline weekly hours. Add the categories together for total FTE. For example, 10 part-time workers at 20 hours under a 40-hour baseline equal 5.0 FTE.
With a 40-hour baseline across 52 weeks, 1.0 FTE is 2,080 hours per year. If your organization uses a 37.5-hour week, 1.0 FTE is 1,950 hours. The calculator uses whatever baseline and weeks you enter.
There is no single target. Professional services and tech companies often run 85% to 95%. Retail and hospitality may run 30% to 70% because part-time and seasonal staffing are normal. Compare your ratio to your own past periods and your industry’s staffing model.
Headcount counts people. FTE counts work capacity. Ten part-time workers at 20 hours each are 10 headcount but only 5.0 FTE under a 40-hour baseline. That difference matters for budgeting, benefits, and capacity planning.
Yes. Enter contractors under their own category using their average weekly hours. Treat them the same way you treat employees for FTE math. The result shows contractor FTE separately and as a share of your total workforce.
FTE exceeds headcount when average weekly hours are above the baseline. That can happen from overtime, long contractor weeks, or a baseline set lower than the actual full-time schedule. The calculator flags any ratio above 100% so you can check the inputs.
Use their average weekly hours across the full year, not their peak-season hours. If a seasonal worker logs 35 hours per week for 12 weeks, their annualized average is about 8.08 hours per week. Enter that figure so the FTE reflects the full year.
No. A full-time employee is a person. FTE is a unit of measure. One full-time employee usually equals 1.0 FTE, but part-time and contract workers also count toward FTE based on their hours. The term describes capacity, not employment status.
0.5 FTE means half of a full-time schedule. Under a 40-hour baseline, that is 20 hours per week. Two workers at 0.5 FTE each equal one full-time equivalent. The calculator shows fractional FTE values to two decimal places.
It can help you estimate FTE counts, but ACA reporting has specific measurement periods and rules that vary by employer size and jurisdiction. Use the calculator as a planning aid, then confirm the final figures with a qualified benefits or payroll professional.
Yes. Run the calculation once per location, then add the FTE totals together for a company-wide figure. The tool does not store or compare locations, so you will need to keep the separate results in your own spreadsheet.
