Full-time Equivalent (FTE)

Full-time equivalent (FTE) is a unit that converts scheduled hours into a share of one standard workweek. One FTE equals one person on a full schedule, so finance and HR teams can compare mixed rosters and outsourced capacity on a single scale.

Headcount tells you how many bodies you employ. FTE tells you how many workweeks of labor you actually buy.

That gap matters when one team blends full-time workers, part-timers, contractors, and offshore staff on a single P&L line.

The metric turns up everywhere finance meets labor. Payroll forecasting, Affordable Care Act (ACA) reporting in the US, offshore staffing quotes, and productivity ratios all lean on a clean FTE count. Get it wrong and every downstream number drifts.

Key takeaways

• One FTE equals one worker at a standard 40-hour week, so two half-timers total 1.0 FTE.
• The formula is total scheduled hours divided by hours in one full-time workweek.
• Under the ACA, 50 FTEs is the US employer coverage mandate threshold.
• Offshore vendors quote in FTEs to strip out shift, benefits, and overtime noise.
• FTE feeds budgeting, capacity planning, and outsourcing cost comparisons.

How it works

To calculate FTE, add every worker’s scheduled hours over a set period, then divide by the hours one full-time employee works in that same period. Most US employers use 2,080 hours a year, or 40 hours a week, as the divisor.

The formula stays simple: total scheduled hours ÷ standard full-time hours = FTE. A worker on 20 hours a week counts as 0.5 FTE, and two of them roll up to 1.0 FTE.

A contractor booked for 60 hours a week still caps at 1.0 under headcount-mandate rules but shows as 1.5 for capacity planning. That split is why compliance FTE and planning FTE belong in separate columns of the same model.

The divisor also changes by country, so a global model needs one row per region. Monthly hours below are just the annual figure divided by 12.

Global demand for outsourced FTE capacity keeps climbing. Precedence Research valued the business process outsourcing (BPO) market at USD 347.95 billion in 2025, growing at a 10.05% compound annual rate through 2035.

Vendors slice that spend into FTE-priced seats across call center, back office, and contact center roles.

Philippine providers lead the supply side. The IT and Business Process Association of the Philippines counted roughly 1.9 million sector workers in 2024.

Its industry roadmap to 2028 targets 2.5 million workers — 600,000 more people, or about 32% growth in four years.

Buyers then compare quotes per FTE, sidestepping local benefits, offshoring taxes, and shift premiums.

Examples

FTE math shows up any time hours don’t line up neatly. Two part-timers at 20 hours each book 1.0 FTE. A BPO directory listing quoting USD 1,200 per FTE means one dedicated 40-hour offshore agent.

ACA compliance in the US. An employer with 30 full-timers and 40 part-timers averaging 20 hours a week counts 30 + (40 × 20/40) = 50 FTEs — right at the mandate line.

Miss that count and the shared-responsibility penalty lands per uncovered full-time worker, not per FTE. Part-time hours are the piece most often under-counted.

Offshore staffing quotes. A Philippine vendor quoting a contact center seat at USD 1,500 a month per FTE bundles the agent’s 40-hour salary, workstation, HR, and PEO fees. That’s USD 18,000 a year per seat.

The same seat run in-house in the US costs USD 4,500–6,000 a month fully loaded, per Clutch’s 2024 buyer surveys. Take the narrow end of that spread, USD 3,000 a month, and a 20-seat team carries a USD 720,000 annual gap.

Capacity planning at scale. A SaaS support desk needs 12,480 monthly agent-hours. Divide by the 173 monthly full-time hours in the table and you get 72 FTEs — the exact staffing plan for the next quarter.

Split that number between in-house and outsourced FTEs using the staff leasing vs seat leasing vs BPO vs BOT decision matrix, then shortlist against the Top 40 BPO companies in the Philippines.

Payroll processing costs. Per OA’s outsourced payroll breakdown, Philippine providers charge USD 6–15 per employee each month, while US in-house payroll runs USD 45–80.

That is a monthly spread of USD 30–74 a head. Across 100 FTEs it works out to USD 36,000–88,800 a year before anyone touches salary. See benefits of outsourcing your payroll services for the fuller picture.

US employers also carry admin duties per FTE that never show up in a vendor quote — a defined pay cycle, a registered employer identification number (EIN), and a duty to report new hires to the state directory.

Miss any of the three and the true per-FTE cost sits above the sticker price. Buyers building side-by-side models often start from the staff leasing vs full outsourcing offshoring framework.

• Business Process Outsourcing: the delivery model that most often quotes capacity in FTEs.
• Offshoring: moving FTE-priced work to a lower-cost country.
• Knowledge Process Outsourcing: higher-skill FTEs such as analysts, engineers, and researchers.
• Service Level Agreement: the contract terms defining what each funded FTE must deliver.
• Back Office: an FTE-heavy function that sits alongside customer support.

FAQ

These are the questions buyers and payroll teams ask most about FTE. One rule sits under every answer: fix your full-time divisor first, and every ratio, budget, and vendor quote downstream stays comparable.

Is one FTE always a 40-hour worker?

No. FTE = 1.0 is whatever your organization calls a full-time week. Most US employers use 40 hours, while UK and EU firms often set the divisor at 37 or 37.5.

How do I calculate FTE from a mixed part-time and full-time roster?

Add every worker’s weekly scheduled hours, then divide by your standard full-time week. Ten full-timers plus twenty half-timers on 20 hours gives (10 × 40 + 20 × 20) ÷ 40 = 20 FTE.

Why do outsourcing vendors quote per FTE instead of per hour?

FTE pricing bundles salary, benefits, workstation, and management overhead into one predictable monthly number. It lets you compare a Manila seat with a Denver seat without redoing tax and benefits math every time.

Does an FTE include overtime hours?

Standard FTE math counts scheduled full-time hours only, so overtime is tracked separately and capacity forecasts stay stable. Many payroll systems flag any worker above 1.0 FTE for compliance review.

What counts as an FTE under the US Affordable Care Act?

The ACA treats anyone averaging 30 or more hours a week, or 130 or more hours a month, as full-time. Part-time hours roll up into equivalents, and 50 total FTEs triggers the employer coverage mandate.

Where does FTE fit inside the wider outsourcing decision?

FTE is the pricing unit, and vendor selection sits inside the broader Ultimate Guide to Outsourcing framework covering scoping, geography, and governance before any quote is signed.
