How pro rata salary works

Your pro rata salary is your full-time annual salary multiplied by your hours divided by full-time hours. Take-home pay is calculated on the resulting annual salary.

Worked example

At 22.5 hours out of 37.5, £40,000 full-time becomes £24,000.00 a year. The default take-home estimate is £1,733.30 a month.

Common questions

Does take-home pay fall by the same percentage?

Usually not. Tax and NI thresholds mean deductions change at different rates. We recalculate deductions on your part-time pay.

Can I enter overtime?

This tool covers hours up to your full-time hours. Overtime is outside this pro rata calculation.
