Pay rises, inflation and what your money really buys
6 min read · Updated 2026-10-12 · MoneyCalc
A pay rise of three per cent feels like an improvement, and it is one in name. If prices rose by four per cent over the same period, your income went up and your purchasing power went down. The gap between the two is the number that matters, and it is invisible unless you calculate it.
Nominal versus real
Nominal income is the number on your payslip. Real income is that number adjusted for inflation — what it buys after prices have moved. A one per cent rise with three per cent inflation is a two per cent fall in real terms, spread over a year.
Over a career this compounds quietly. Someone whose income has risen with inflation every year has preserved their position; someone whose income has fallen behind has seen their standard of living erode in a way that never shows up as a single large loss.
Inflation is not uniform
Headline inflation is an average across a basket, and the basket does not match anyone's actual spending. Housing, energy and food move differently, and in a period when one of them spikes the average understates what most households feel.
For personal decisions, the figure that matters is the rate of inflation in the things you actually buy. Someone who has just moved is far more exposed to housing costs than the headline number suggests.
The same logic applies to investments
A deposit paying five per cent with six per cent inflation loses purchasing power despite a positive headline return. The real return is the nominal return minus inflation, and it can be negative while every number on the statement looks healthy.
Fees matter here in the same way. A fund charge of one per cent against a return of five is a fifth of the gain consumed before tax, which is why the real return calculation should be done after costs rather than before.
What to do with the number
Track real income rather than salary across job moves, salary reviews and over several years. It is the only figure that tells you whether you are getting better off, and it is the one most people never calculate.
When real income is falling, the responses are limited and worth knowing in advance: move, change hours, adjust spending, or accept it knowingly. What is not useful is discovering it retrospectively over a decade.

Common questions
Does a pay rise always mean more money?
No. If inflation was higher than the raise, your real income — what your pay actually buys — has fallen even though your payslip is larger.
How do I calculate my real income?
Take the percentage change in your nominal pay and subtract the inflation rate over the same period. The difference is the change in your real income.
Can my investment return be negative when it is positive?
Yes. If an investment returns five per cent and inflation is six, the real return is negative one per cent, before fees and tax.
