Full-time equivalent (FTE) calculator

FTE stands for full-time equivalent.

FTE counts staff by hours: total hours worked a week divided by full-time hours. Two people on 18.75 hours each make one FTE at 37.5 hours.

The formula

FTE = total hours a week ÷ full-time hours

Worked example: 8.0

The example is a UK software company in one month: £50,000 of revenue excluding VAT, 400 customers and £180,000 in the bank.

300 hours ÷ 37.5 = 8.0 FTE
