Full-Time Equivalent

What is FTE, or Full Time Equivalent?

FTE or Full-Time Equivalent is used by organizations to measure the number of full-time employees they have. Interestingly, FTE is not calculated based on the number of people in the company, but rather on the total hours worked. Let’s say your company defines 40 hours per week as full-time. 

Here’s how you can calculate your FTE count:

So, even if you have four people working part-time, they might only contribute the workload of one full-time employee.

FTE is especially handy for long-term or large-scale projects, such as construction or engineering. These projects often involve diverse teams and can stretch over several months. By summarizing planning to a single number that accounts for both time and headcount, it simplifies things significantly. Additionally, it enables organizations with a mix of full-time, part-time, and contract employees to easily compare everyone’s contributions on a uniform scale.

Why is FTE Important for Employers?

Understanding FTE and applying it helps employers manage their workforce more effectively. Let’s walk through five key ways FTE is helpful for employers: 

1. Assigning relevant roles and departments

One of the easiest ways to utilize FTE is to use it in workforce planning. Managers and HR teams use FTE data to determine the number of employees needed in a department based on actual workload rather than  just the number of available employees or open positions.

2. Project planning and management

In creative agencies, for example, you can have someone working on several small projects in a week. In product development or software engineering, you may need someone to work on one project full-time for several months.

FTE helps you to estimate:

• How many people (full-time) do you need for a project
• Can your current team take on new work
• How to distribute the project load between different types of employees

3. Budgeting and cost management

Every employee incurs a cost based on the role, hours worked, experience, and benefits. FTE provides employers a viable means to align staffing plans with financial constraints.

When creating  budget plans, teams use FTE to:

• Forecast work effort and labour cost across departments.
• Adapt hiring based on estimated workload. Prevent future overstaffing or understaffing by estimating the capacity required for the expected output. 
• Ensure projects are allocated to employees who can realistically deliver the work.

4. Understanding capacity by role

By defining capacity per role, FTE helps us evaluate outputs against expectations. It also plays an important role in outsourcing decisions, creating shifts, and balancing workload.

5. Ensuring compliance with employment and labor laws

FTE calculations determine compliance with federal regulations. For instance, the Affordable Care Act requires employers with 50+ FTEs to provide healthcare coverage and benefits eligibility.

How To Calculate FTE?

Step 1: Set standard full-time hours.

Determine your company’s standard full-time work week. Most companies use 40 hours per week as their baseline; some 37.5 hours or 35 hours, depending on their policies or country regulations. For this example, we’ll use the standard 40-hour work week.

Step 2: Collect employee hours.

Gather the actual hours worked by each employee during your calculation period. For example, X works 40 hours per week as a full-time marketing manager. Y works 30 hours per week as a part-time graphic designer. Z works 20 hours per week as a part-time content writer. Record these hours carefully as they are the basis of your FTE calculation.

Step 3: Divide total hours by standard hours.

The basic formula for calculating FTE is:

FTE = Total hours worked ÷ Standard (or full-time) work hours

Step 4: Calculate individual FTE.

Calculate each employee’s FTE using their actual hours. For instance, let’s calculate the individual FTEs of the marketing team, comprising X, Y, and Z. By applying the above formula, 

FTE for X who works 40 hours: 40 hours ÷ 40 standard hours = 1.0 FTE

FTE for Y who works 30 hours: 30 hours  ÷ 40 standard hours = 0.75 FTE

FTE for Z who works 20 hours: 20 hours ÷ 40 standard hours = 0.5 FTE

These individual calculations show the proportion of a full-time position each person represents.

Step 5: Calculate the Total FTE.

To derive the total capacity for your department, add the individual FTEs together. For example, the marketing team has a total of 1.0 + 0.75 + 0.5 = 2.25 FTE. In this case, three people are doing the work equivalent of 2.25 full-time employees. 

To calculate annual hours, you take the total hours worked by all employees for the year and divide by the standard yearly hours. 

Common Uses of FTE in HR and Payroll 

FTE serves as the universal language for HR and payroll departments for measuring workforce capacity. 

The following are some common use cases of FTE for these departments:

• Staffing requirements: FTE provides a clear understanding of the current staffing needs, as well as forecasts future hiring needs.
• Budget planning: Organizations can use FTE to assess labor costs by measuring different employment types in comparable terms, which allows for more accurate budgeting.
• Benefits administration: FTE can identify the benefit eligibility and prorated eligibility for part-time employees.
• Payroll harmonization: For HR, an FTE clarifies the working hours and salary of its part-time employees.
• Workload distribution: FTE aids in workload distribution and organizations also gain clarity on its staffing levels and expected outcomes.
• Overtime management: FTE is applied to calculate hours worked by all employee types, including temporary and flexible workers.
• Cross-department comparisons: FTE data helps evaluate and compare staffing levels across different business units, adding valuable insights.

FTE vs. Headcount: Key Differences

FTE and headcount are often used interchangeably but are different terms.

Headcount is simply a count of how many people comprise a team. If you employ five people, you have a headcount of 5. This is regardless of whether their weekly work hours add up to 10 or 50.

FTE is a more meaningful metric than headcount. It measures actual work capacity, not just team size. 

For example, a team of 5 people might only add up to 3.5 FTEs if some are part-time. In many cases, 3 full-time employees can accomplish more than 6 part-time ones.
