Full-Time Equivalent (FTE)
Definition, rules and examples

A full-time equivalent (FTE) is a unit that converts part-time and full-time hours into the number of full-time workers those hours represent. One FTE equals the hours of one full-time employee.

Definition: Full-time equivalent (FTE) is a measure that expresses total hours worked, or scheduled, as a number of full-time employees. For example, two employees each working half of a full-time schedule equal 1.0 FTE. The IRS uses a specific FTE method under the Affordable Care Act.

What FTE means

Headcount tells you how many people are on payroll. FTE tells you how much work capacity they represent. A store with 10 employees could have 10 full-time workers or 3 full-time and 7 part-time workers, and the staffing, labor cost, and benefit implications are very different. FTE turns hours into a common unit so you can compare locations, set budgets, and plan schedules.

There are two different uses of the term. In everyday operations and budgeting, employers choose their own full-time standard, often 40 hours a week or 2,080 hours a year. For federal health coverage rules, the IRS uses a specific definition with a 30-hour full-time standard and a separate FTE formula. Keep the two calculations separate.

How to calculate FTE for staffing and budgets

The basic formula is total hours worked (or scheduled) in a period divided by the hours one full-time employee works in that period.

Worked example (hypothetical, 40-hour standard): A coffee shop tracks one week of hours.

Employee groupEmployeesHours eachTotal hours
Full-time baristas340120
Part-time baristas520100
Weekend staff41040
Total12260

FTE = 260 ÷ 40 = 6.5 FTE. The shop has a headcount of 12 but the work capacity of 6.5 full-time employees. If sales suggest the shop needs 7.0 FTE on a typical week, managers know they need about 20 more hours of coverage, which could come from extra part-time shifts rather than a new full-time hire.

For annual planning, divide annual hours by 2,080 (40 hours × 52 weeks). An employee scheduled 1,560 hours a year is 1,560 ÷ 2,080 = 0.75 FTE.

How the IRS counts FTEs under the ACA

The Affordable Care Act’s employer shared responsibility provisions apply to applicable large employers (ALEs). According to the IRS page Determining if an employer is an applicable large employer:

  • An employer with at least 50 full-time employees, including full-time equivalent employees, on average during the prior year is an ALE for the current year.
  • A full-time employee is one who averages at least 30 hours of service per week in a calendar month, or at least 130 hours of service in that month.
  • To count FTEs, add the monthly hours of service of all employees who are not full-time, counting no more than 120 hours for any one employee, and divide the total by 120.
  • If an employer exceeds 50 full-time employees, including FTEs, for 120 days or fewer during the calendar year and the employees in excess of 50 during that period were seasonal workers, the employer is not considered an ALE.

The IRS gives an example: an employer with 40 full-time employees and 20 part-time employees who each work 60 hours a month has 1,200 ÷ 120 = 10 FTEs per month. Its annual average is (480 + 120) ÷ 12 = 50, so it is an ALE.

Worked example (hypothetical): For one month, a restaurant group has 38 employees who average more than 30 hours a week and 10 employees who log 140 hours of service each. Because 140 is at least 130 hours, the IRS definition treats those 10 as full-time too, for 48 full-time employees. It also has 20 part-time employees who each log 70 hours. FTEs for the month = (20 × 70) ÷ 120 = 1,400 ÷ 120 = 11.67. Full-time plus FTEs = 48 + 11.67 = 59.67 for that month. ALE status depends on the average across all months of the prior year, so the group would repeat this calculation every month. Misclassifying the 140-hour employees as part-time would not change this month’s total by much, but it could lead to errors in which employees must be offered coverage, which is why accurate hours data and review with a benefits professional matter.

FTE and labor cost planning

FTE is also a building block for labor budgeting. Multiply FTEs by the average hourly cost and the hours in a full-time week to estimate weekly labor spend, then compare it with sales to find your labor cost percentage. Tracking scheduled FTE versus actual FTE each week shows whether schedules are drifting from plan through overtime, early clock-ins, or unplanned coverage.

Why FTE matters for scheduling

Schedulers often think in shifts, but FTE helps translate shift plans into staffing targets. If a location’s budget allows 8.0 FTE on a 40-hour standard, it has 320 hours to allocate each week. Any combination of full-time and part-time shifts that stays within 320 hours fits the budget. Comparing planned FTE with actual FTE after the week ends shows how much extra time came from overtime, late clock-outs, or unplanned coverage, and helps managers adjust the next schedule.

Best practices

  1. Document the full-time standard you use for internal FTE reporting.
  2. Calculate ACA FTEs separately using the IRS method, with its 30-hour and 120-hour rules.
  3. Use actual hours worked from time records, not scheduled hours, for compliance counts.
  4. Review FTE monthly by location to catch growth that may change ALE status.
  5. Track seasonal workers clearly so the seasonal exception can be evaluated.

Common mistakes

  • Using headcount instead of FTE when comparing locations or budgeting.
  • Applying a 40-hour standard to ACA calculations instead of the IRS 30-hour and 130-hour rules.
  • Failing to cap part-time hours at 120 per employee per month in the ACA FTE formula.
  • Counting employees above 130 monthly hours as part-time.
  • Calculating from schedules that do not match actual hours.

How EZTime helps

Accurate FTE counts start with accurate hours. EZTime captures time through the GPS mobile time clock with geofencing, NFC tags, tablet kiosk, or biometric clocks, and AI shift scheduling with shift templates helps plan hours to a target staffing level. Overtime and break alerts keep weekly hours on plan, timecard corrections keep an audit trail, and payroll-ready Excel/PDF exports give you hours by employee and period to calculate FTEs or share with any payroll software or benefits advisor.

Frequently asked questions

Divide total hours worked in a period by the hours one full-time employee works in that period. For example, 260 weekly hours divided by a 40-hour standard equals 6.5 FTE.

Add the monthly hours of service of employees who are not full-time, counting no more than 120 hours per employee, and divide by 120. Full-time means averaging at least 30 hours per week or 130 hours in a month.

No. Headcount is the number of people employed. FTE is the number of full-time workers their combined hours represent.

According to the IRS, at least 50 full-time employees, including full-time equivalent employees, on average during the prior year, subject to a seasonal worker exception.
