How it works
FTE = hours per week ÷ full-time hours per week. Hours per year = hours per week × weeks worked. Average hours per month = hours per year ÷ 12.
Worked examples
- 25 hours a week, 40-hour full-time week, 52 weeks: 25 ÷ 40 = 0.63 FTE; 1,300 hours a year; 108.33 hours a month on average.
- 32 hours a week, 40-hour full-time week, 52 weeks: 0.80 FTE; 1,664 hours a year; at or above the 30-hour IRS line.
- 20 hours a week, 37.5-hour full-time week, 48 weeks: 20 ÷ 37.5 = 0.53 FTE; 960 hours a year.
