Written by Salary.com Staff
June 06, 2025
FTE is a metric that represents the actual number of full-time employees required to complete work. Headcount is the total number of employees in the payroll.

In today’s highly competitive business landscape, organizations must manage their workforce both with precision and efficiency. A recent study shows 83% of companies produce workforce information to monitor, assess, and improve overall performance.

Whether in HR, finance, or project management, implementing key workforce metrics such as FTE vs headcount is essential for accurate workforce planning, resource allocation, and financial forecasting. Both of these crucial terms are fundamental, yet they serve distinct purposes and provide different insights into your organization’s human resources.

In this comprehensive guide, we’ll discuss everything you need to know about FTE vs headcount. What does each of them mean? What are their key differences? And how do you calculate them? Let’s find out!

What is full-time equivalent (FTE)?

Full-time equivalent or FTE refers to the standardized metric used to represent the company’s total workforce in terms of the number of full-time employees required to complete a given amount of work. In other words, it quantifies the total hours worked by all employees as if they were performed by employees with full-time status.

Instead of simply counting the number of employees, full-time equivalent converts the hours worked by all employees, including full-time, part-time, and contractual workers, into the equivalent number of full-time positions:

Why use FTE?

Companies use FTE because it provides a more accurate metric for comparing employees' workloads, labor costs, and workforce capacity across departments, projects, or even entire organizations.

Who uses FTE?

FTE is typically used by HR professionals, hiring managers, financial planners, and project managers for workforce planning, resource management, and compliance with labor laws.

The full-time equivalent metric is also essential to accurately forecast and establish your compensation planning practices. It’s a core element of your organization’s salary planning strategies, allowing you to implement a competitive pay structure for your employees.

When and how to use FTE

The FTE value is very helpful in various scenarios encountered by every organization. Here are some key instances when you can use the full-time equivalent:

  • Workforce planning

  • Resource allocation

  • Financial planning

  • Regulatory compliance

  • Comparing productivity

  • Managing job descriptions

Below are some practical and real-world scenarios where FTE could be applied by companies (note that the standard weekly and annual hours worked are 40 and 2080, respectively):

Situation 1: A company employed 10 part-time workers, each working 20 hours per week. By calculating the FTE, the HR department can determine how many full-time employees this equates to, ensuring a more accurate talent management system and workforce capacity planning

Situation 2: During headcount planning for a new project, managers may use FTE to assess if they have enough full-time equivalent employees to meet project deadlines, allowing them to adjust their budget and timeline accordingly.

How to calculate FTE

Simply put, calculating the FTE generally involves converting the total number of hours worked by all your employees into the equivalent number of full-time positions. Here’s a step-by-step guide you can follow for FTE calculation:

  1. Establish the formula: Get to know the components of the formula and what each figure represents: FTE = Total weekly hours worked/full-time hours

  2. Determine full-time hours: Define what constitutes full-time hours in your organization (typically 40 hours per week in the U.S.).

  3. Calculate total hours worked: Add up all the hours worked by full-time, part-time, and contract workers over a specified period (weekly, monthly, or annually).

  4. Divide by full-time hours: Divide the total hours worked by the number of hours a full-time employee would work in the same period.

Example: If Company ABC employed 6 full-time employees and 4 part-time employees, what would be the total FTE? (Assuming full-time and part-time hours to be 40 and 20, respectively)

Solution:

For full-time: 6 × 40 hours = 240 hours

For part-time: 4 × 20 hours = 80 hours

Total hours worked = 240 + 80 = 320 hours

FTE = 320 hours / 40 hours = 8 FTE

Therefore, the workforce of Company ABC is equivalent to 8 full-time employees, in spite of having employed 10 workers in total.

What does headcount mean?

Headcount refers to the total number of employees on an organization’s payroll, regardless of their employment status. So, whether an employee works full-time, part-time, or contractual, one head counts as 1.

Compared to FTE, headcount is a straightforward measure of all the employees, each counted as one, irrespective of their working hours. Tallying the total headcount of your workforce helps you forecast essential aspects of business success.

Utilizing the Compensation Planning Software together with an accurate workforce headcount helps you mitigate errors, increase efficiency, streamline collaboration, and centralize your planning in a single comprehensive system.

When and how to use headcount

Headcount may seem to be simple, but it’s definitely a strategic tool used in several HR and management aspects, such as the following:

  • Workforce size: Helps you quickly assess the size of your workforce.

  • Compliance: Meet regulatory requirements that depend on the number of employees, such as labor laws or tax credits.

  • Organizational structure: Helps you construct an effective resource management model and properly allocate employees according to the number of direct reports, team sizes, or department sizes.

  • Headcount analysis: Track hiring trends, turnover rates, and workforce growth over time.

Below are some practical and real-world scenarios where headcount is applied by companies:

Situation 1: The sales department uses headcount to accurately forecast the budget and total cost for commission payouts, whether it’s monthly, quarterly, or annually.

Situation 2: Hiring managers compare headcounts across departments to identify areas that may need additional staffing and adjust their workforce planning strategies accordingly.

How to calculate headcount

In contrast to the calculation of full-time equivalent, determining the headcount involves direct counting and is indeed a more straightforward approach:

  1. Establish the headcount formula: Headcount = Total number of employees

  2. List all employees: Include full-time, part-time, and contract workers.

  3. Count each employee once: Everyone, regardless of actual hours worked, is counted as a single employee.

Example calculation: Company DEF has the following number of employees: what would be the total headcount?

Full-time employees = 10

Part-time employees = 6

Contract workers = 8

Solution: Headcount = 10 + 6 + 8 = 24

Therefore, the total headcount for Company DEF is 24, since every employee counts as one, regardless of their employee hours or employment type.

Headcount vs FTE: Key differences

Understanding the distinction between headcount vs FTE is crucial for effective workforce management. Here’s a table showing the clear differences between headcount vs FTE:

Headcount vs FTE: Key differences

To sum it up, headcount gives a snapshot of organizational size and is essential for compliance and reporting. Meanwhile, FTE offers a more accurate metric for understanding workforce capacity, labor costs, and employee productivity, especially when managing a mix of full-time and part-time workers.

FAQs

Below are common questions about headcount vs FTE:

How do you convert FTE to headcount?

To convert FTE to headcount, you need to know the mix of full-time and part-time employees. Since FTE is based on hours worked, while headcount is a simple count of individuals, there is no one-size-fits-all formula.

However, if all employees are full-time, FTE and headcount will be the same. If you have part-time workers, the headcount will be higher than FTE.

Example: 7 FTE could be made up of 5 full-time employees (5 headcount) and 4 part-time employees (each working half-time, so 2 FTE), for a total headcount of 9.

What is the headcount rule?

The headcount rule refers to regulatory or compliance thresholds based on the number of employees. For example, under the Affordable Care Act (ACA), employers with 50 or more full-time equivalent employees must provide health insurance.

How many hours is 0.6 FTE in 40 hours?

0.6 FTE × 40 hours/week = 24 hours/week

Therefore, 0.6 FTE is equal to 24 hours per week.
