Teacher Pay Rise Calculator

The Teacher Pay Rise Calculator shows what a teaching pay award is actually worth in your pocket once Income Tax, National Insurance and your Teachers' Pension contribution are taken out. A headline figure like the 4% rise that took effect from 1 September 2025 sounds simple, but the amount you keep is always lower — and if the increase pushes you into a higher pension contribution tier, you keep even less. This tool gives you a clear side-by-side comparison of your take-home pay before and after the rise, using the latest 2026/27 tax, NI and Teachers' Pension figures for teachers in England.

It is built for classroom teachers, ECTs, middle and senior leaders, and supply teachers on the School Teachers' Pay and Conditions (STPCD) scales who want to know the real value of an STRB award or a move up the pay spine. Enter your current salary, the percentage rise and your student loan plan, and you will see the gross increase, the net increase, your effective "kept" percentage and the extra cash per month. It is an estimate for guidance — your payslip is the final word.

How the teacher pay rise calculator works

The calculator runs your old and new salary through the same 2026/27 deduction stack and compares the two take-home figures:

1. New gross salary = current salary × (1 + rise%).
2. Teachers' Pension is deducted first under the net-pay arrangement, using the tiered member rate for your salary band (7.4% up to £36,198.99, then 8.9%, 9.9%, 10.5%, 11.6% and 12% — bands effective 1 April 2026).
3. Income Tax is applied to salary after pension: a £12,570 personal allowance, 20% to £50,270, 40% to £125,140 and 45% above.
4. National Insurance (Class 1, employee) is 8% on earnings between £12,570 and £50,270, then 2% above.
5. Student loan (if selected) is 9% above your plan threshold, or 6% above £21,000 for a Postgraduate Loan.

The difference between the two net figures is your real pay rise. Because tax, NI and pension all take a slice, most teachers keep roughly 65–75% of a headline rise — less if the rise crosses a pension tier boundary, which the calculator flags for you.

Worked example: a 4% rise on £30,000

Take a teacher on £30,000 receiving the 4% award, with no student loan:

• New gross salary: £30,000 × 1.04 = £31,200 — a gross rise of £1,200.
• Both salaries sit in the lowest pension tier, so the contribution rate stays at 7.4%.
• Old take-home: £30,000 − £2,220 pension − £3,042 tax − £1,394.40 NI = £23,343.60.
• New take-home: £31,200 − £2,308.80 pension − £3,264.24 tax − £1,490.40 NI = £24,136.56.
• Net rise: £792.96 per year (about £66.08 per month) — roughly 66.1% of the £1,200 headline figure.

So a "4% pay rise" is worth closer to 2.6% in real take-home terms for this teacher — the rest goes to the pension that funds your retirement, plus tax and NI.

Frequently asked questions

Why is my teacher pay rise worth less than the headline percentage?

Every extra pound of salary is taxed at your marginal rate (20%, 40% or 45%), charged National Insurance (8% or 2%), and a percentage goes to your Teachers' Pension. Combined, that typically leaves a teacher keeping around 65–75% of a gross rise. If the rise lifts you into a higher pension tier, your whole salary — not just the increase — is charged the higher contribution rate, reducing the net gain further.

What was the 2025 teacher pay award?

Following the School Teachers' Review Body (STRB) recommendation, the Government applied a 4% uplift to teacher pay and allowances in England from 1 September 2025. The next STRB process determines the 2026 award. You can model any percentage in the calculator above.

Does the calculator include the Teachers' Pension?

Yes. It deducts the tiered member contribution under the net-pay arrangement using the bands effective 1 April 2026, ranging from 7.4% to 12% depending on your salary. Because contributions are taken before Income Tax, you also get tax relief on them automatically.

Is this accurate for Scotland, Wales and Northern Ireland?

The Income Tax bands used are for England and Northern Ireland. Scotland has its own income tax rates, so Scottish teachers should treat the result as indicative. National Insurance and Teachers' Pension rates apply UK-wide, but pension schemes and pay scales differ in Scotland and Northern Ireland.
