Free FULL-TIME EQUIVALENT CALCULATOR

What is a full-time equivalent (FTE)?

A full-time equivalent (FTE) is a unit of measurement that expresses workforce capacity as if every team member worked a standard full-time schedule. It lets you compare staffing levels across teams, departments, or businesses even when the mix of full-time and part-time work differs.

The core formula is:

FTE = Total weekly hours / Standard full-time hours per person

When full-time team members exist, this calculator derives the standard from your data: Full-time hours / Full-time employees. For example, if 10 full-time employees work 400 hours per week and 10 part-time employees work 200 hours per week, the total is 600 hours. The standard is 400 / 10 = 40 hours per person, so FTE = 600 / 40 = 15.0. Your 20 people deliver the same capacity as 15 full-time workers.

How to use this FTE calculator

This calculator converts employee counts and weekly hours into a clear FTE number in seconds. Follow these steps:

1. Gather workforce data: collect employee counts and combined weekly hours for both full-time and part-time groups.
2. Enter full-time employees: type the headcount in the Full-time employee field.
3. Enter full-time hours: type the combined weekly hours for all full-time staff, such as 400 for ten 40-hour workers.
4. Enter part-time details: type the part-time headcount and their combined weekly hours.
5. Read the FTE result: the total updates instantly at the bottom of the calculator.
6. Compare scenarios: adjust inputs to model hiring plans or schedule changes, then use reset to start fresh.

Key features

Instant FTE calculation

Results update in real time as you type, with no calculate button needed.

Full-time and part-time inputs

Separate fields for full-time and part-time employee counts and hours give you a clear breakdown.

Automatic standard derivation

The calculator derives standard full-time hours per person from your full-time data instead of hardcoding 40 hours.

Part-time-only support

If you have no full-time employees, set the count to 0 and enter the benchmark weekly hours in the full-time hours field. The calculator uses that value as the standard.

Input validation

Accepts whole numbers between 0 and 99,999. Decimal points, negative signs, and exponent notation are blocked.

Local storage persistence

Your inputs are saved automatically in the browser so you can close the tab and return later.

No sign-up required

The tool is free, runs entirely in your browser, and never asks for an email address or credit card.

FTE and the Affordable Care Act (ACA)

In the United States, employers with 50 or more full-time equivalent employees may be classified as Applicable Large Employers (ALEs). The IRS uses a specific method for ACA calculations:

1. Count employees who average 30 or more hours per week; each counts as one full-time employee.
2. Sum the monthly hours of all remaining part-time employees.
3. Divide the part-time total by 120 to get part-time FTE for the month.
4. Add full-time count plus part-time FTE. If the result is 50 or more, the employer may be an ALE.

This calculator gives a quick weekly-hours estimate. For ACA compliance, use IRS guidance for Forms 1094-C/1095-C or speak with a benefits advisor.

Common uses for FTE

• Budgeting and forecasting: translate headcount into labor cost projections regardless of how hours are distributed.
• Benefits eligibility: estimate workforce thresholds and allocate benefits costs per FTE.
• Productivity benchmarking: compare revenue per FTE, output per FTE, or cost per FTE across teams and time periods.
• Grant and contract reporting: many grants and contracts require FTE disclosures to justify funding.
• Staffing analysis: identify whether adding part-time roles or converting to full-time is more cost-effective.
• Headcount planning: translate project requirements into FTE needs so managers can plan hiring and scheduling.

FTE vs. headcount: what is the difference?

Headcount is the raw number of people on your roster. FTE normalizes that count by hours worked. A team of 20 people, with 10 full-time at 40 hours and 10 part-time at 20 hours, has a headcount of 20 but an FTE of 15. FTE gives a more accurate picture of actual workforce capacity.

Who benefits from calculating FTE?

• HR professionals: standardize workforce reporting, track staffing levels over time, and estimate ACA exposure.
• Finance teams: budget labor costs accurately by normalizing headcount into FTE units.
• Operations managers: plan shift coverage and resource allocation based on true capacity rather than raw headcount.
• Small business owners: understand staffing capacity and make informed hiring decisions.
• Grant writers and administrators: report FTE accurately in funding applications and compliance documents.
