One Standard Worker: The Logic of the Full-Time Equivalent
In a hurry? Skip straight to the numbers.
Open the FTE (Full-Time Equivalent) Calculator →Grant budgets express staff not in people or raw hours but in a curious unit: the full-time equivalent, or FTE. This standardized measure of labor solves a real problem — that “full-time” means different things in different places — and it makes it possible to charge exactly the right slice of a person's salary to a grant.
The Problem of Counting People
Counting staff by headcount is misleading: two half-time workers are not the same labor as two full-time ones, and one person split across projects is not fully any of them. To budget and compare labor fairly, a unit is needed that captures how much work is actually being done, independent of how many bodies do it. That unit is the full-time equivalent.
Defining a Standard
The FTE expresses staffing as a fraction of one standard full-time schedule. A person working full-time is one FTE; someone working half a full schedule is half an FTE. Because it references a defined standard rather than raw hours, it turns any mix of part-time, full-time, and shared staff into a single comparable measure of labor input.
| Schedule | FTE |
|---|---|
| Full-time | 1.0 |
| Half-time | 0.5 |
| Quarter-time | 0.25 |
Why “Full-Time” Varies
The FTE matters precisely because organizations define full-time differently — some as a longer standard week, others shorter. Raw hours are therefore not comparable across organizations, but converting to FTE against each one's own standard creates a common language. The FTE is a translation device that lets labor be compared and combined despite differing definitions.
Charging Time to a Grant
The FTE's practical power in grants is precise cost allocation. When a grant funds only part of a person's time, that person's FTE fraction on the grant, multiplied by their salary, gives exactly the personnel cost that should be charged. For staff split across several funders, this keeps each grant paying its fair share — accurate, defensible, and audit-ready.
Calculating FTE
To convert a schedule to full-time equivalents, use the FTE Calculator. Fold personnel into a budget with the Program Budget Calculator, and estimate contracted help with the Grant Writer Hourly Rate Calculator.
