Real Wage Growth Calculator

When a Raise Is Actually a Pay Cut

A 3 percent raise in a 5 percent inflation year is a real pay cut of about 1.9 percent. The salary figure went up and what it buys went down, which is why a payslip and a shopping basket can tell opposite stories about the same year. Any time prices rise faster than pay this happens, and the size of the gap is the whole question. The International Labour Organization tracks real wage growth across regions for that reason: a nominal figure on its own does not say whether pay improved.

The Fisher Equation

Real rate equals one plus the nominal rate, divided by one plus the inflation rate, minus one. That is the Fisher relation, written for interest rates originally and applied here to wages, and it is the accurate way to take inflation out of a percentage. The familiar shortcut of subtracting inflation from the nominal figure is close at small numbers and drifts as they grow: at 3 against 5 it gives -2.00 where the exact answer is -1.90, a tenth of a point out, while at 30 against 25 it gives 5.00 against an exact 4.00, a full point out. This calculator uses the exact form.

A worked example

With the defaults, a current salary of 60,000, a nominal raise of 3 percent and inflation of 5 percent, the tool returns -1.90%. The salary itself rises to 61,800, but measured in today's money that is 58,857, so the year costs roughly 1,143 of purchasing power despite the pay going up.

What moves the number most

Only two of the three inputs touch the headline percentage. The real raise depends on the nominal raise and the inflation rate and nothing else, so the same -1.90% comes back whether the salary is 30,000 or 300,000. Current Salary drives the two cash figures beneath it, the new nominal salary and its value in today's money, and leaves the percentage alone. Between the two that do matter, neither dominates: they enter as a ratio, so adding a point to the raise moves the answer to -0.95% and taking a point off inflation moves it to -0.96%, almost the same distance.

The formula behind this

The real raise comes from the Fisher relation above. The new nominal salary is the current salary multiplied by one plus the nominal raise. The new real salary divides that by one plus inflation, which expresses next year's pay in this year's money so the two figures can be compared directly.

Reading the real figure

The real figure is what the money buys; the nominal figure is what the letter says. A positive real raise means pay moved ahead of prices over the period entered, a negative one means it did not, and zero means the raise exactly held the line. None of that speaks to whether the raise was fair, or whether the inflation rate entered matches the prices a particular household actually faces, since the calculation applies one uniform rate to everything bought.
