The real figure divides rather than subtracts: (1 + raise) ÷ (1 + inflation) − 1. Subtracting the two percentages is close at small numbers and drifts once either gets large, which is exactly when the question matters.

How the Pay Raise Calculator works

A raise in cash, per month, and in real terms against inflation. The real figure uses (1 + raise) ÷ (1 + inflation) − 1 rather than subtracting the two percentages, which is close at small numbers and drifts once either gets large.

Why real change divides rather than subtracts

The instinct is to subtract: a 4% raise against 3% inflation feels like 1% ahead. The correct form divides — (1 + 0.04) ÷ (1 + 0.03) − 1 = 0.97% — and the difference here is small enough to look like rounding.

It stops looking like rounding as the numbers grow. A 10% raise against 8% inflation is 1.85% real, not 2%. A 30% raise against 25% inflation is 4% real, not 5%. The subtraction error is always in the optimistic direction, and it grows with both inputs.

The reason is that the two percentages apply to different bases. The raise applies to your salary; inflation applies to the prices you face after the raise. Dividing puts them on the same footing, which is what the Fisher relation does and why it is the standard form in economics rather than a refinement.

Compounding across a career

Raises multiply rather than add. Three consecutive years at 3% is 1.03³ = 1.0927, a 9.27% total increase, not 9%. Over a long career the gap between the two ways of counting becomes substantial.

The same compounding works against you when raises trail inflation. Three years at 2% against 4% inflation leaves real pay down about 5.7%, and nothing about the payslip announces it — the number went up each year. Real erosion is quiet by construction.

This is why a cost-of-living adjustment is worth naming as separate from a merit raise. A COLA holds real pay flat and is not a reward for anything; a merit raise moves you forward. Where an employer folds the two together into a single number, real progression can be zero for years while every review looks positive.

Negotiating with the right anchor

Asking for a percentage anchors the conversation to your current salary, which is precisely the number you are arguing is too low. Asking for a specific figure supported by market data for the role moves the anchor to what the work is worth, and those are very different conversations.

Market evidence beats personal need, uncomfortable as that is. Rent rising is a real problem and it is not an argument an employer can act on without creating one for every colleague. Comparable roles paying more is an argument that connects directly to their risk of losing you.

The structural reason internal raises trail external moves is compression: a new employer prices you at the current market rate while your existing employer prices you off your history. That gap is what a market adjustment is meant to correct, and asking for one by name — rather than for a raise — is often the more productive framing.

Frequently asked questions

How do I calculate a pay raise?

Multiply your current salary by 1 plus the percentage. A 4% raise on £50,000 gives £52,000, an increase of £2,000 or about £167 a month before deductions.

Is a 3% raise good?

Only against inflation. If prices rose 5%, a 3% raise is a real-terms pay cut of about 1.9%. If inflation was 1%, the same 3% is a genuine improvement of about 2%.

Why not just subtract inflation from the raise?

Because both are percentages of different bases. The correct form is (1 + raise) ÷ (1 + inflation) − 1. A 10% raise against 8% inflation is 1.85% real, not 2% — and the gap widens as both numbers rise.

What is a typical annual raise?

It varies enormously by country, sector and year, and the honest answer is to check current survey data for your own market rather than trust a remembered figure. What matters more is whether it beats inflation and what the market rate for your role has done.

Does a raise increase my tax proportionally?

Not usually — only the portion falling in a higher band is taxed at the higher rate. You always keep more after a raise, though the take-home increase is smaller than the gross one.

Should I negotiate on percentage or on the final number?

On the final number. A percentage anchors the conversation to your current pay, which is precisely the figure you are arguing is too low. Market rate for the role is a stronger anchor than your own history.
