Part-Time Teacher Salary Calculator
Teachers' part-time pay is calculated differently from support staff. Under the School Teachers' Pay and Conditions Document (STPCD), part-time teachers receive a fraction of the full-time salary for their pay point, based on their timetabled teaching sessions compared to the school's full-time equivalent sessions.
Unlike support staff who use weekly hours, teachers' part-time fractions are based on sessions or periods taught. A teacher working 3 out of 5 days would typically have a 0.6 fraction.
Teacher Pay Scales 2025/26 (England)
| Scale Point | Full-Time | 0.8 (4 days) | 0.6 (3 days) | 0.4 (2 days) |
|---|---|---|---|---|
| Main M1 | £30,000 | £24,000 | £18,000 | £12,000 |
| Main M3 | £33,814 | £27,051 | £20,288 | £13,526 |
| Main M6 | £41,333 | £33,066 | £24,800 | £16,533 |
| Upper U1 | £43,266 | £34,613 | £25,960 | £17,306 |
| Upper U3 | £46,525 | £37,220 | £27,915 | £18,610 |
How Teacher Fractions Are Set
Your school determines your timetable fraction based on the number of sessions you are contracted to teach versus the school's maximum. This is negotiated when accepting the role and documented in your contract. Common fractions include 0.4 (2 days), 0.5 (2.5 days), 0.6 (3 days), and 0.8 (4 days).
PPA time (10% of teaching time) is included proportionally. A 0.6 teacher still receives 0.6 of the PPA allocation. For support staff pay in schools, use the schools calculator which uses NJC pay scales instead of STPCD.

Worked Example: Part Time Teacher Salary Calculator
Let's work through a real example of using a part time teacher salary calculator. Sarah is a school teaching assistant on a full-time equivalent salary of £23,500. She works term-time only (38 weeks) at 30 hours per week, while the full-time role is 37.5 hours per week for 52 weeks.
Step 1 — Calculate the hours pro rata: 30 ÷ 37.5 = 0.8 FTE
Step 2 — Calculate the weeks pro rata: (38 + 5.6 holiday weeks) ÷ 52.143 = 0.8356
Step 3 — Apply both adjustments: £23,500 × 0.8 × 0.8356 = £15,710 per year
This gives Sarah a monthly gross pay of approximately £1,309. However, because her pay is spread across 12 months, she receives the same amount each month even during school holidays.

Common Mistakes With Part Time Teacher Salary Calculator Results
- Forgetting holiday weeks: Term-time pay isn't just term weeks × weekly rate. You must add 5.6 weeks of statutory holiday to your term weeks before dividing by 52.143. Many employers include this in your annual hours calculation.
- Using 52 instead of 52.143: There are 365.25 days in a year (accounting for leap years), which gives 52.143 weeks — not exactly 52. This small difference affects your annual salary by up to £100.
- Confusing teaching and support staff scales: Teachers and support staff use completely different pay scales. Teaching assistants should use their local authority pay grade, not the Teachers' Pay Scale.
- Not including INSET days: Most contracts include 5 teacher training (INSET) days in addition to term weeks. Check whether your 38 or 39 weeks includes or excludes INSET days.
According to ACAS guidance, your employer should provide a clear breakdown of how your term-time salary is calculated. If the figures don't match, raise it with HR or contact ACAS for free advice.
Pro Rata Holiday Entitlement
Under the Working Time Regulations 1998, all UK workers are entitled to a minimum of 5.6 weeks' paid holiday per year (28 days for full-time). If you work part-time, your entitlement is calculated pro rata based on your actual hours or days worked.
| Days Worked/Week | FTE Ratio | Statutory Days/Year | Bank Holidays (pro rata) |
|---|---|---|---|
| 5 days (full-time) | 1.0 | 28 days | 8 days |
| 4 days/week | 0.8 | 22.4 days | 6.4 days |
| 3 days/week | 0.6 | 16.8 days | 4.8 days |
| 2.5 days/week | 0.5 | 14 days | 4 days |
| 2 days/week | 0.4 | 11.2 days | 3.2 days |
Holiday entitlement is always rounded up — never down — when the result is not a whole number, per ACAS guidance on holiday entitlement. Bank holidays may be included in or added on top of your statutory 28 days, depending on your contract.
All calculations on this page follow ACAS pro rata pay guidelines and are consistent with the UK Employment Rights Act 1996. Tax figures use HMRC 2025/26 rates. The April 2025 National Living Wage of £12.21/hour is applied where relevant.

Frequently Asked Questions
Pro rata means "in proportion." In employment, it refers to adjusting a full-time salary proportionally based on the number of hours, days, or weeks actually worked compared to a full-time equivalent role.
Divide the full-time salary by full-time hours, then multiply by your actual hours. For example: £30,000 ÷ 37.5 hours × 25 hours = £20,000 pro rata.
Pro rata salary is usually calculated before holiday pay. Your holiday entitlement is also pro-rated — part-time workers get 5.6 weeks holiday pro rata, calculated proportionally to hours worked.
Not exactly. Pro rata is the method used to calculate part-time salary. It ensures part-time workers receive the proportional equivalent of the full-time rate, maintaining fairness under UK employment law.
