Real wage growth calculator
Calculate how wage growth compares with price growth over the same interval. Enter two percentage changes with matching starting and ending periods.
Use the ratio, not just subtraction
Real wage growth = (1 + nominal wage growth) ÷ (1 + price growth) − 1, with both inputs expressed as decimals. The result is then multiplied by 100 to express it as a percentage. A 5% wage increase and a 3% price increase produce approximately 1.94% real growth. Subtracting the two percentages gives a useful rough approximation but does not reproduce the ratio exactly.
If wages rise more slowly than the chosen price index, the result is negative. A zero result means wages and the selected price measure grew by the same proportional amount. This calculation describes a completed interval; it does not forecast future wages or inflation.
Match the periods and the population
A year-over-year wage change must be paired with a year-over-year price change for the same endpoints. Do not combine one month’s wage change with twelve months of inflation. Use the same adjustment basis where appropriate. Keep a record of the wage definition, deflator, start period and end period when publishing a result.
An average hourly earnings series can change when the mix of workers changes. Its growth is not necessarily the raise received by a particular person. A compensation index can include employer benefits that an earnings measure excludes. A household income figure is another concept again. Choose the numerator that matches your question before selecting a price index.
Interpret the estimate
A CPI deflator approximates purchasing power for the consumer population covered by that index. It is not automatically an appropriate deflator for business revenue, an industrial input or an individual household’s basket. Aggregate real wage growth cannot establish what happened to every worker. Employment changes and the distribution of pay can matter alongside an average.
Both growth inputs must be greater than −100% so their underlying positive level ratios remain meaningful. Missing or nonnumeric inputs are rejected. Inputs stay in your browser. The result is an educational calculation and does not provide a recommendation about investing or borrowing.
