Pro Rata Salary Calculator UK: Part-Time and Term-Time Pay

Work out the gross pay for a part-time, term-time or part-year role from the full-time salary. This calculator shows gross pay only. It does not work out tax, National Insurance or pension contributions.

Gross pay only, before tax, National Insurance and pension. This is general information. Your contract or your employer’s payroll method decides the exact figure.

How pro rata salary is worked out

Pro rata means “in proportion”. A part-time salary is the full-time salary multiplied by the share of full-time hours that the person works. That share is often called the full-time equivalent, or FTE. Acas explains that pay and leave for part-time workers are given pro rata.

• FTE = actual hours a week ÷ full-time hours a week
• Pro rata annual salary = full-time salary × FTE
• For a term-time role, multiply again by paid weeks ÷ 52
• For part of a year, multiply the annual figure by calendar days in the job ÷ 365

Worked example

A job is advertised at £30,000 a year for 37.5 hours a week. You will work 22.5 hours a week. Your FTE is 22.5 ÷ 37.5 = 0.6, or 60%. Your pro rata salary is £30,000 × 0.6 = £18,000 a year, which is £1,500 a month before deductions.

This calculator divides the annual figure by 12 for monthly pay and by 52 for weekly pay. The hourly rate is the full-time salary divided by 52 weeks and then by the full-time weekly hours. Some employers use 52.143 weeks or count working days instead of calendar days, so payroll figures can differ slightly.

Questions about pro rata pay

How do I work out my pro rata salary?

Divide the hours you work each week by the full-time hours, then multiply the full-time salary by the result. For example, a job paid £30,000 for 37.5 hours a week pays £18,000 a year if you work 22.5 hours, because 22.5 ÷ 37.5 is 0.6.

What is 30,000 salary pro rata?

It depends on how much of the full-time week you work. With a 5-day full-time week, £30,000 pro rata is £18,000 a year for 3 days a week, which is £1,500 a month. For 4 days a week it is £24,000 a year, which is £2,000 a month. These are gross figures, before tax, National Insurance and pension.

What is the formula to calculate pro rata?

Pro rata salary = full-time salary × (your weekly hours ÷ full-time weekly hours). For a term-time role, multiply the result by paid weeks ÷ 52. For part of a year, multiply the annual figure by the calendar days in the job ÷ 365.

What does 25k pro rata mean?

It means £25,000 is the salary for the full-time hours. You are paid the share of it that matches the hours you work. For example, if you work 3 days and full time is 5 days, you get £15,000 a year, which is £1,250 a month before deductions.

What is FTE?

FTE stands for full-time equivalent. It shows a part-time role as a share of a full-time one. Someone who works 30 hours in a team where full time is 37.5 hours has an FTE of 0.8, or 80%.

How is a term-time only salary worked out?

A common method is to multiply the pro rata salary by the number of paid weeks, including paid holiday weeks, divided by 52. Employers use different formulas for term-time pay, so check your contract or ask your payroll team which one applies to you.

Does this calculator show take-home pay?

No. It shows gross pay, which is pay before tax, National Insurance and pension contributions are taken off. Your take-home pay will be lower and depends on your tax code and pension scheme.
