Full-Time Equivalent (FTE)

Counting employees sounds simple until the workforce includes part-time staff, job sharers, people on reduced hours and seasonal workers. Ten people might represent ten full-time workloads, or they might represent five. To compare teams, plan capacity and budget costs accurately, organizations need a measure of how much work the workforce can actually do, not just how many people are on the payroll. The full-time equivalent, or FTE, provides that measure. It converts all hours worked into the number of full-time employees those hours represent.

FTE is used widely across business, government, healthcare and education. Finance teams use it to budget labor costs, HR teams use it to track capacity, project managers use it to staff projects and public agencies use it to report staffing levels. It also has specific legal uses: in the United States, the Affordable Care Act uses a full-time equivalent calculation to determine whether an employer is an applicable large employer subject to its coverage requirements. For finance leaders, HR teams, managers and anyone planning workforce capacity, FTE is one of the most basic and most frequently used workforce measures.

Definition of Full-Time Equivalent (FTE)

A full-time equivalent is a standardized measure of workforce capacity calculated by dividing the total hours worked or scheduled by the number of hours that make up a full-time schedule, such that one FTE represents one full-time worker and part-time work is expressed as a fraction.

It is the main unit used in headcount planning, a key input to workforce planning and a common denominator in measures such as revenue per employee.

How to Calculate FTE

Decide what counts as full time. Many organizations use 40 hours a week, or about 2,080 hours a year, though some use 35 or 37.5 hours.

Add up the hours worked or scheduled by all employees in the group for the period.

Divide the total by the full-time hours for that period. For example, 200 scheduled hours in a 40-hour week equals 5 FTE.

For individuals, divide their scheduled hours by full-time hours. A person working 20 hours in a 40-hour week is 0.5 FTE. Over a year, the same logic applies. An employee scheduled for 1,040 hours against a 2,080-hour standard is 0.5 FTE.

FTE Versus Headcount

Headcount counts people, regardless of hours. Ten part-time employees are ten heads.

FTE counts capacity. Ten employees each working half time equal five FTE.

Headcount is useful for space planning, benefits administration and organizational reporting, while FTE is better for capacity, productivity and cost analysis.

Gaps between headcount and FTE show how much of the workforce is part time, which can matter for scheduling and benefits. Reports should always state which measure they use, since the same team can look very different in headcount and FTE.

Importance of FTE in Workforce and Operations

FTE makes capacity comparable. Teams with different mixes of full-time and part-time staff can be compared on a consistent basis.

It improves planning. Staffing models, project plans and service levels can be built in FTE, then translated into specific hires or schedules.

It also supports compliance and reporting. Some regulations, grants and public reporting requirements are based on FTE counts rather than headcount. Under the Affordable Care Act, for example, employers combine part-time hours into full-time equivalents to determine whether they have at least 50 full-time employees.

FTE and Financial Management

Budgets often express labor in FTE multiplied by a cost per FTE, which makes it easy to model the effect of adding or removing capacity.

Cost per FTE should be fully loaded, including salary, benefits, taxes and overhead, to reflect the true cost of capacity.

Productivity measures such as revenue per FTE or transactions per FTE give fairer comparisons than per-headcount measures when part-time work is common.

Contractor capacity can also be expressed in FTE, helping leaders compare the cost of employees and contractors for the same work.

Common Challenges

Organizations may define full time differently across countries or units, making FTE totals inconsistent.

Some reports use scheduled hours while others use hours worked, which differ when overtime, leave or absence is significant.

Legal definitions, such as the Affordable Care Act's full-time threshold of 30 hours a week, may differ from the organization's own definition.

FTE hides differences in skill and productivity, since one FTE of a junior role and one FTE of a senior role are counted the same. Productive capacity is also lower than paid FTE once vacation, training and absence are taken into account, which planners often call shrinkage.
