Days assume a 5-day full-time week and scale the hours for you.
Pension is worked out on your actual part-time pay, the same way as the main calculator: auto-enrolment is a % of qualifying earnings (£6,240–£50,270), and pension comes off before income tax but not before National Insurance. Choose "No pension" if you are not in a scheme.

How this is calculated
Your actual salary is the full-time salary multiplied by your hours divided by full-time hours (or days out of 5). Tax, National Insurance, pension and student loan are then worked out on the actual salary by the same engine as the take-home pay calculator — so the part-time figure is a full payslip, not a rough fraction. Pension defaults to auto-enrolment (5% of qualifying earnings); change it in the pension box — including switching it off — and the take-home updates. Because the £12,570 personal allowance does not shrink when you work fewer hours, part-time take-home is usually a bigger share of gross than full-time: at £24,000 you keep 83.7% of your pay, against 77.4% at £40,000.

Examples — part-time at common patterns
| Pattern | Actual salary | Take-home / year | Take-home / month |

| £40,000 full-time, 3 of 5 hrs/wk | £24,000.00 | £20,089.20 | £1,674.10 |

| £45,000 full-time, 18.75 of 37.5 hrs/wk | £22,500.00 | £19,069.20 | £1,589.10 |
Auto-enrolment pension at 5% of qualifying earnings, no student loan.
Questions
What is my salary if I work 3 days a week on £40,000 full-time?
£24,000 a year — three fifths of £40,000. Your take-home pay would be £20,089.20 a year (£1,674.10 a month) with the usual auto-enrolment pension, against £30,969.20 a year full-time. Part-time pay is not simply pro-rata take-home: because tax bands and thresholds are fixed, working fewer hours usually means you keep a bigger share of each pound.
How is part-time salary worked out?
Actual salary = full-time salary × (your hours ÷ full-time hours). A £30,000 full-time job at 20 hours of a 37.5-hour week is £16,000 a year. Tax, National Insurance, pension and student loan are then worked out on the actual salary by the same engine as the main calculator.
Do I still pay pension part-time?
Usually yes, if you are auto-enrolled — the same 5% of qualifying earnings applies, but qualifying earnings are worked out on your actual part-time pay. At £24,000 a year the employee pension is £888.00 a year. If your pay falls below the £10,000 auto-enrolment trigger, your employer does not have to enrol you.
What if my full-time week is 40 hours, not 37.5?
Change the full-time hours in the box above — the fraction is worked out from your hours. A £40,000 job at 24 hours of a 40-hour week is £24,000, the same as 3 days of 5, but at 20 hours it is £20,000, not £21,333.
Is my pay sent anywhere?
No. The calculator runs entirely in your browser. No figure you enter is sent to a server, stored, or shared.
