How the calculation works
FTE annual salary = part-time salary × full-time hours ÷ part-time hours. Monthly = FTE annual ÷ 12. Weekly = FTE annual ÷ 52. Working percentage = part-time hours ÷ full-time hours × 100.
Worked example
£18,000 part-time, 22.5 part-time hours, 37.5 full-time hours. FTE annual = £18,000 × 37.5 ÷ 22.5 = £30,000. Monthly = £2,500. Weekly ≈ £576.92. Working percentage = 60.0%.

Frequently asked questions
What is a full-time equivalent (FTE) salary?
FTE is what your current part-time pay would scale up to if you worked full-time hours. FTE = part-time salary × full-time hours ÷ part-time hours.
Why do recruiters use FTE figures?
FTE makes part-time and full-time roles comparable on a like-for-like basis. It is widely used in job adverts, salary surveys, public sector pay scales and HR reports.
Is FTE the same as my salary if I returned to full-time?
It is the proportional equivalent. Your employer may apply different bonus, allowance or pension terms when you actually switch back to full-time.
