About the Inflation-Adjusted Salary Calculator
This inflation-adjusted salary calculator tells you whether your pay has really gone up. A raise only improves your standard of living if it grows faster than prices; otherwise your real salary — what your pay can actually buy — falls even though the number on your paycheck rises.
Enter your old and new salary and the time between them, then either an average annual inflation rate or the consumer price index (CPI) at the start and end of the period. The calculator shows the salary you would need just to keep pace with inflation, your new salary expressed in the old year’s money, the real percentage change and the real annual raise you received.
It is useful before a salary review, when comparing a job offer with your current pay, or when tracking how your earnings have held up over several years. For the most accurate answer, use official CPI figures (for example CPI-U from the U.S. Bureau of Labor Statistics, or your country’s statistics office) for the exact months of your old and new pay.
With the default inputs, the real change in purchasing power is -1.03%. Change any value above to recalculate instantly.
How to use the inflation-adjusted salary calculator
- 1Enter your starting salary and your current or offered salary.
- 2Enter how many years separate them.
- 3Choose an average inflation rate, or enter the CPI at the start and now.
- 4Read the real change and the salary needed to keep pace.
- 5Use the gap figure as evidence in a salary negotiation.
Formula and method
The inflation factor F measures how much prices rose between the two salaries: either the average annual rate compounded over n years, or simply the ratio of the two CPI readings. Multiplying your old salary by F gives the pay needed to buy the same basket of goods today; dividing your new salary by F expresses it in the old year’s money.
Real change compares your new salary with the inflation-matched salary. The real raise per year is the annualised version: (New ÷ Old ÷ F)^(1/n) − 1. The chart smooths your raise evenly over the period (compound growth) so it can be compared with the inflation path year by year.

Worked examples
$60,000 to $63,000 over 2 years at 3% inflation
Two years of 3% inflation raises prices 6.09%, so you would need $63,654 to stand still. Your 5% raise to $63,000 falls $654 short: in starting-year money it is worth $59,384, a real pay cut of about 1%.
CPI method: $50,000 to $55,000 while CPI went from 300 to 315
CPI rose 5%, so keeping pace required $52,500. The 10% raise to $55,000 beats that by $2,500, a real increase of 4.76% in purchasing power.
$75,000 to $90,000 over 5 years at 2.5%
Five years of 2.5% inflation means $84,856 would merely keep pace. At $90,000 you are $5,144 ahead — a 6.06% real gain, or about 1.2% a year above inflation.
Frequently asked questions
How do I know if my raise beat inflation?+
Compare your percentage raise with inflation over the same period. If prices rose 6% and your pay rose 5%, your real salary fell about 1%. This calculator compounds inflation correctly and shows the exact salary needed to break even.
What is real salary?+
Real salary is your pay adjusted for inflation — what it can buy compared with a base year. Nominal salary is the number on your paycheck. A rising nominal salary can still mean a falling real salary when prices rise faster.
Which inflation figure should I use?+
In the US, the CPI-U published monthly by the Bureau of Labor Statistics is the standard measure. Use the index values for the months your old and new salaries started. Other countries publish equivalent consumer price indices through their statistics offices.
What is a cost-of-living adjustment (COLA)?+
A COLA is a raise meant only to offset inflation, keeping real pay flat. Merit raises are on top of it. If your employer’s total increase is below inflation, you effectively received a pay cut in real terms.
Why does my personal inflation differ from CPI?+
CPI tracks an average basket of goods. If you spend more than average on rent, childcare or fuel, your personal inflation rate may be higher or lower. You can enter your own estimated rate in the average inflation field.
