To calculate full-time equivalent (FTE) employees, first pick the full-time standard that matches your purpose — 30 hours per week under the Affordable Care Act, or 40 hours per week for budgeting and most federal grants — then convert your workforce’s paid hours into whole full-time positions using the formula tied to that standard. The same headcount produces different FTE totals under each method, so the choice of standard is part of the calculation, not a preliminary detail.
Pick the Right Full-Time Standard First
Two standards do almost all the work.
The 30-hour weekly standard comes from 26 U.S.C. § 4980H. A full-time employee is anyone averaging at least 30 hours of service per week, or 130 hours in a calendar month. Use this standard when determining whether your business is an Applicable Large Employer (ALE) and when calculating the Small Business Health Care Tax Credit. Because the bar is lower, more employees qualify as full-time, and your FTE count runs higher.1Office of the Law Revision Counsel. 26 U.S. Code 4980H – Shared Responsibility for Employers Regarding Health Coverage
The 40-hour weekly standard — 2,080 hours per year — is the baseline for internal workforce planning, departmental budgets, and most federal grant reporting. The Office of Management and Budget uses this figure for federal workforce estimates.2GAO.gov. Full-Time Equivalent (FTE) Employment
Identify which reporting requirement prompted the calculation, then lock in the corresponding threshold. Mixing the two produces numbers that satisfy neither.
Which Hours and Which Workers Count
An “hour of service” for ACA purposes includes every hour an employee is paid or entitled to payment, whether or not any work was actually performed. Vacation, holidays, sick leave, disability, jury duty, military leave, and layoff hours all count. Overtime counts too, because the definition covers every paid hour without distinguishing regular time from overtime.3eCFR. 26 CFR 54.4980H-1 – Definitions
The caps depend on which calculation you’re running. For ALE status, no employee can be credited with more than 120 hours of service in any single month.4Internal Revenue Service. Determining if an Employer Is an Applicable Large Employer For the Small Business Health Care Tax Credit, the cap is 2,080 hours per employee for the year, and anything above that is discarded.5Internal Revenue Service. Small Business Health Care Tax Credit and the SHOP Marketplace
Some hours are excluded entirely: work performed by bona fide volunteers, students in a Federal Work-Study Program, and employees whose compensation qualifies as income from sources outside the United States.3eCFR. 26 CFR 54.4980H-1 – Definitions
Not everyone on your payroll counts as an employee for FTE purposes:
- Independent contractors (1099 workers) are not employees and do not appear in any FTE calculation.
- For the Small Business Health Care Tax Credit, sole proprietors, partners, S-corp shareholders owning more than 2%, and C-corp shareholders owning more than 5% are excluded — as are their spouses, children, grandchildren, siblings, parents, in-laws, and the spouses of those family members.6Internal Revenue Service. Small Business Health Care Tax Credit Questions and Answers: Determining FTEs and Average Annual Wages
- For ALE status, if your workforce only exceeds 50 full-time employees (including FTEs) for 120 days or fewer during the year and the excess consists of seasonal workers, you are not treated as an ALE. The 120 days need not be consecutive, and four calendar months can substitute.7eCFR. 26 CFR 54.4980H-2 – Applicable Large Employer and Applicable Large Employer Member
Calculating FTEs for ALE Status
A business that averaged at least 50 full-time employees (including FTEs) during the prior calendar year is an ALE and must offer health coverage or face penalties.4Internal Revenue Service. Determining if an Employer Is an Applicable Large Employer The calculation runs month by month, then averages across the year.
The Monthly Calculation
For each calendar month:
- Count every employee who averaged at least 30 hours of service per week, or 130 hours for the month. Each is one full-time employee.
- Add the hours of service for every other employee that month, capping each person at 120 hours regardless of what they actually worked.
- Divide that total by 120. The result is your FTE count for the month.
- Add the full-time headcount from step 1 to the FTE count from step 3. That’s your combined total for the month.4Internal Revenue Service. Determining if an Employer Is an Applicable Large Employer
Averaging Across the Year
Add the 12 monthly combined totals and divide by 12. If the result is 50 or more, your business is an ALE for the following calendar year.
Say a company has 35 full-time employees every month plus part-time staff whose capped hours total 1,800 in a given month. Dividing 1,800 by 120 produces 15 FTEs. The monthly combined count is 35 + 15 = 50. Hold that pattern for 12 months and the average is 50 — the company is an ALE.
Calculating FTEs for the Small Business Health Care Tax Credit
Smaller employers claiming the health care tax credit use a different formula. Instead of separating full-time and part-time workers, combine everyone’s hours into a single pool.5Internal Revenue Service. Small Business Health Care Tax Credit and the SHOP Marketplace
- Add the total hours of service for all employees during the tax year, capping any single employee at 2,080.
- Divide the total by 2,080. That’s your FTE count for the credit.
Under this method, 48 half-time employees produce 24 FTEs.6Internal Revenue Service. Small Business Health Care Tax Credit Questions and Answers: Determining FTEs and Average Annual Wages The IRS defines one FTE as 2,080 hours here, not 30 hours per week. That’s a deliberate departure from the ALE standard, so don’t blend the two.
Calculating FTEs for Budgeting and Grants
For internal budgeting, staffing analysis, or federal grant reporting, most organizations use the 40-hour weekly standard. Divide total hours worked by all employees during the period by the number of full-time hours in that same period.2GAO.gov. Full-Time Equivalent (FTE) Employment
The annual denominator is 2,080 (40 hours × 52 weeks). The weekly denominator is 40. If part-time staff worked a combined 1,200 hours in a week, dividing by 40 gives 30 FTEs. Add that to your full-time headcount for the complete picture. Individual grant programs sometimes define the reporting period differently, so check the specific grant’s instructions for the correct denominator before you file.
Related Businesses Are Combined
If your business shares common ownership with other companies, you likely cannot calculate FTEs in isolation. Under Section 414 of the Internal Revenue Code, companies with a common owner or that are otherwise related are combined and treated as a single employer for ALE purposes.4Internal Revenue Service. Determining if an Employer Is an Applicable Large Employer
If the combined group meets the 50-employee threshold, every employer in the group becomes an ALE member, even one that would fall well below 50 alone. Corporation Y with 40 full-time employees and sister Corporation Z with 60 have a combined count of 100, making both ALEs. Penalty liability is calculated separately for each member, but the coverage obligation applies to each one.
What Getting the ALE Count Wrong Costs in 2026
The reason precision matters is the employer shared responsibility penalties. For 2026, the IRS has set inflation-adjusted amounts of $3,340 per full-time employee per year under Section 4980H(a) — the penalty for failing to offer minimum essential coverage to at least 95% of full-time employees and their dependents when at least one full-time employee receives a marketplace premium tax credit — and $5,010 per affected employee per year under Section 4980H(b) for coverage that fails to provide minimum value or is unaffordable.8Internal Revenue Service. Revenue Procedure 2025-26 An employer with 100 full-time employees that offers no coverage could face a Section 4980H(a) penalty above $334,000 for the year. Undercounting FTEs and mistakenly assuming you fall below 50 is one of the more expensive errors a growing business can make.
Records and Reporting
Accurate numbers start with accurate payroll data. Pull reports from your payroll or time-tracking system that capture every employee’s total paid hours for the measurement period, including regular time, overtime, vacation, sick leave, and holidays.6Internal Revenue Service. Small Business Health Care Tax Credit Questions and Answers: Determining FTEs and Average Annual Wages Organize the data so you can identify full-time status on a month-by-month basis. A spreadsheet with each employee’s name, employment status, and monthly hours makes the math manageable and gives you something to hand the IRS if a filing is questioned.
The IRS allows three ways to count hours of service: actual hours from time records, a days-worked equivalency crediting 8 hours per day, or a weeks-worked equivalency crediting 40 hours per week. You can use different methods for different categories of employees, but you must apply the same method consistently within each category.
ALEs report workforce data on Forms 1094-C and 1095-C. Form 1094-C is the transmittal and includes monthly counts of full-time employees in Part III; Form 1095-C carries individual employee coverage details.9Internal Revenue Service. Instructions for Forms 1094-C and 1095-C For the 2025 calendar year, paper returns are due March 2, 2026 and electronic returns are due March 31, 2026. The general rule for future years is end of February for paper and March 31 for electronic, with weekend or holiday deadlines shifting to the next business day. Keep your underlying worksheets — the monthly hour totals, per-employee caps, and the division producing each month’s FTE number — with your filed forms. Those are your primary defense in an audit.
