PROMOTION PAY · 2026/27
Salary after promotion calculator
See how much extra gross pay a promotion adds before you factor in tax, National Insurance and pension contributions.
What this calculator does
Use this page to compare current and promoted salary, then review the gross increase before deductions. It is especially useful when a new role changes your headline pay but not necessarily your take-home pay by the same amount.
Estimated result
- Monthly gross increase
- £833
- Additional pension
- £500
- Increase after pension before tax
- £9,500
Use the take-home calculator for Income Tax, NI and student-loan effects.
Worked example
A move from £45,000 to £55,000 shows a £10,000 gross increase, but the amount that reaches your pocket will depend on tax, NI and any pension changes. The first thing to check is the net monthly increase, not the headline uplift.
Common mistakes
Do not compare gross promotion pay only.
Do not forget pension and student-loan deductions may rise too.
Do not treat the first payslip as the whole annual picture.
Why the result can differ
Pension contributions, student loans and tax codes can change the net increase.
A promotion can change payroll deductions even when the gross uplift looks the same.
Regional tax rules matter if the salary crosses a threshold.

Why two users can see different results
Why the result can differ
Different tax codes, payroll periods, Scottish bands, pension methods or lender assumptions can change the outcome.
One-off bonuses, pay frequency, overpayments, allowances and reliefs can move the result away from a simple annual estimate.
Where a rule depends on eligibility or legal status, this page shows an estimate and links to official guidance.
This section is intentionally repeated on key tools so the explanation stays near the result instead of being hidden in a separate policy page.
COMMON QUESTIONS
Frequently asked questions
Does this show take-home pay?
No. It only compares gross salary before deductions.
Can pension contributions change the result?
Yes. A higher pension deduction can reduce the amount that reaches your bank account.
Is a promotion always worth it?
Not automatically. Pay, commute, pension and workload should all be considered together.
