Salary Hike Calculator UK
Calculate your new salary, increase amount and new monthly pay after a percentage hike.
How it works
Compound interest earns returns on both your original money and the returns already added. Adding a regular monthly contribution accelerates growth further over time.
A = P(1 + r/n)^(nt) + contributions compounded monthly- Longer time horizons benefit most from compounding
- More frequent compounding gives slightly higher growth
- The donut shows how much of your final balance is interest vs money you put in.
Frequently asked questions
How do I calculate a pay-rise percentage?
Subtract the old salary from the new, divide by the old salary and multiply by 100. £30,000 to £33,000 is a 10% rise.
How do I find my new salary after a rise?
Multiply your current salary by (1 + the rise percentage / 100). A 10% rise on £30,000 gives £33,000.
Will my take-home rise by the full percentage?
No. A rise is on gross pay, and part is lost to Income Tax and National Insurance, so your net increase is smaller.
What is a good annual pay rise?
It varies by role and economy, but a rise that beats current inflation increases your real purchasing power.
How does inflation affect a rise?
Your real rise is roughly the percentage increase minus inflation. A 5% rise with 3% inflation is about a 2% real gain.
How do I compare two job offers?
Convert both to the same basis — usually annual gross — and weigh pensions, benefits and travel, not just the headline figure.
Working out a pay rise
A pay rise is the percentage increase between your old and new salary. The two common questions are: what is my new salary after an X% rise, and what percentage is a given new salary? This calculator answers both.
The formulas
New salary = old salary × (1 + rise% / 100). To find the percentage from two figures: rise% = (new − old) / old × 100. Going from £30,000 to £33,000 is (33,000 − 30,000) / 30,000 × 100 = a 10% rise.
Gross vs take-home
A rise is quoted on gross salary, but your take-home increase is smaller because part of it is lost to Income Tax and National Insurance — sometimes at the 40% higher rate. So a 10% gross rise adds rather less than 10% to your bank account.
To gain in real terms, a rise needs to beat inflation. If prices rose 3% over the year, a 3% rise roughly keeps you level, while a 5% rise is about a 2% real increase.
