Where the figures come from
This sum uses only the numbers you entered.
What pro rata means
Pro rata means in proportion. A job advertised at £30,000 pro rata pays £30,000 for full-time hours, and a share of it for fewer hours. Divide your hours by the full-time hours to get your share, then multiply the salary by it.
Your share is also called your full-time equivalent, or FTE. Working 22.5 hours where full time is 37.5 is 0.6 FTE.
| Hours a week | FTE | Salary a year |
|---|---|---|
| 30 | 0.8 | £24,000.00 |
| 22.5 | 0.6 | £18,000.00 |
| 18.75 | 0.5 | £15,000.00 |
| 15 | 0.4 | £12,000.00 |
| 7.5 | 0.2 | £6,000.00 |
Term-time and part-year jobs
If you are paid for only part of the year, enter the weeks you are paid for. The calculator multiplies by that many weeks out of 52.
Employers such as schools and councils often use their own formula, which adds your paid holiday to the weeks you work. If yours does, use the number of weeks it gives, or ask your employer for it.
Part-time rights
Part-time workers should not be treated less favourably than comparable full-time workers, including on pay and holiday. GOV.UK explains part-time workers' rights.
