Think you know how many people are on your team? You might want to think again.
When your workforce includes full-time staff, part-time help, freelancers, and interns, headcount alone doesn’t tell the full story. Full-time equivalent, or FTE, does.
FTE converts scattered hours and varied roles into one standardized number, giving you an accurate overview of how much ground your team is covering and what it’s actually costing you. It's the number to closely watch when planning budgets, tracking productivity, or determining whether you meet thresholds for healthcare coverage or reporting obligations.
In this guide, we’ll explain what FTE is and why it matters—especially for distributed teams working across borders. We’ll also walk through a step-by-step formula to calculate it and explore when, how, and why businesses use it to make smarter workforce decisions.
What is FTE in business?
FTE measures how much work one person does compared to a full-time schedule. A full-time employee equals 1.0 FTE, while a part-time employee counts as less. For example, in a 40-hour workweek, someone working 20 hours is 0.5 FTE, while someone who puts in 10 hours is 0.25 FTE.
As a metric, FTE helps employers evaluate workloads, plan staffing, and determine benefits eligibility—especially when balancing full-time and part-time roles.
Why is FTE important?
Tracking FTE helps organizations manage workloads, allocate resources, and meet legal requirements, especially when roles include a mix of full-time and part-time schedules.
Here are a few reasons why FTE matters:
Budgeting and forecasting
FTE gives you a better handle on labor costs. It makes it easier to plan budgets, predict hiring needs, and assign work based on actual capacity, not just headcount. For example, hiring two part-time employees at 0.5 FTE each might cover the same workload as one full-time hire—but at a lower cost.
Compliance and legal requirements
Many labor laws, tax obligations, and benefits eligibility thresholds hinge on accurate FTE calculations. For example, healthcare and paid leave mandates often apply once a business exceeds a specific number of full-time equivalent employees. Errors in FTE calculations can lead to costly penalties due to noncompliance.
Greater accuracy in performance reviews
FTE helps create fairer evaluations by adding context to individual productivity. Comparing a part-time employee’s output to a full-time employee’s without adjusting for workload can skew results.
For instance, if a part-time employee completes 75% of the output of a full-time colleague but only works 50% of the hours, their performance may actually be stronger. FTE helps normalize these comparisons across different schedules.
How to calculate FTE
Understanding how to calculate FTE gives you a simple way to keep track of team capacity, no matter how many full-time or part-time employees you have.
To get a clear view of total workload, staffing levels, and how close you are to compliance thresholds, here’s a step-by-step breakdown of how to calculate FTE for your team:
- Record your employees and their hours worked: Start by listing all employees who receive a year-end W-2 form, excluding 1099 independent contractors, who aren’t typically counted in FTE calculations. When recording hours, subtract any approved leave—like paid time off or sick leave—from the total.
- Define hours for a full-time position: Establish your standard for a full-time workweek. It could be 40 hours per week, but some organizations use 35 hours or another number, depending on local labor standards or internal policy.
- Determine the total annual hours worked by employees: Multiply the hours per week each employee works by the number of weeks in the year (usually 52).
- Add up the total annual hours for full-time and part-time employees: Combine the total annual hours for every employee, regardless of whether they’re full-time or part-time.
- Compute the FTE for part-time employees: To get an individual part-time employee’s FTE, divide their total annual hours by the total annual hours of a full-time schedule.
- Calculate the total FTE: Add the FTE values for all employees, full-time and part-time, to get your total FTE.
FTE calculation example
Let’s say your company defines full-time work as 40 hours per week, or 2,080 FTE hours per year (40 multiplied by 52). You have three full-time employees, each working 40 hours weekly, and two part-time employees who each work 20 hours weekly.
First, set your standard: Full-time equals 2,080 hours per year.
Next, calculate how many hours each employee works annually. A full-time employee clocks 2,080 hours per year. A part-time employee working 20 hours per week adds up to 1,040 hours annually.
Now, apply the FTE formula. Each full-time employee counts as 1.0 FTE, so 3 full-timers equal 3.0 FTE. For part-time employees, divide 1,040 by 2,080 to get 0.5 FTE. With two part-timers, that totals 1.0 FTE.
Add them together, and your total workforce equals 4.0 full-time equivalent employees.
Streamlined payroll, accurate forecasts
FTE calculations are vital for any business—they help you understand staffing levels and labor costs.
But for global teams, FTE figures matter even more. Every country has its own employment laws, pay standards, and definitions of full-time, part-time, and contractor work. Accurately tracking full-time equivalent employees keeps you compliant, no matter where your team is based.

FAQs
How does FTE differ from headcount?
Headcount refers to the total number of employees you have on staff, regardless of how many hours worked. In contrast, FTE considers how many total hours are being worked relative to a full-time schedule. For example, two part-time employees working 20 hours per week each would count as two in your headcount. But together, they equal just 1.0 FTE. Understanding the difference between headcount and FTE is key to managing labor costs, planning future employment needs, and meeting compliance thresholds.
What does an FTE of 1.0 represent?
An FTE of 1.0 typically represents one full-time employee who works the standard number of hours per week, typically 35 to 40, depending on the company or region. On an annual basis, this usually totals 2,080 hours per year (40 hours multiplied by 52 weeks). This standard full-time equivalent benchmark makes it easier to calculate FTE for part-time employees and compare workloads across your team.
What does .75 FTE mean?
A 0.75 FTE means the employee works 75% of your company’s defined full-time hours. If full-time is 40 hours per week, then a 0.75 FTE equals 30 hours per week, or 1,560 hours per year (30 multiplied by 52). This FTE calculation helps clarify an employee’s workload, which affects scheduling, benefits eligibility, and compensation planning.
Should you include interns when calculating FTE?
Yes, paid interns typically count toward your FTE calculation, especially when estimating total FTE for compliance or labor cost forecasting. If an intern works a consistent schedule, you can convert their hours worked into a full-time equivalent, just like any other employee. However, whether or not to include them may depend on local employment laws and the purpose of your FTE calculation.
How do you calculate the FTE for a single employee?
To calculate FTE for one employee, divide the number of hours per week they work by the number of full-time hours your company defines as a standard workweek. For instance, if full-time at your company is 40 hours and someone works 32, their FTE is 0.8 (32 divided by 40). For annual calculations, use hours per year instead—such as 1,560 divided by 2,080, which equals 0.75 FTE. This method works for full-time employees, part-time workers, and temporary staff alike.
