Cost of Living Adjustment Calculator
Calculate the COLA raise that keeps pace with inflation
Result
How it is calculated
The tool applies a simple percentage uplift: raise = salary × inflation / 100 and adjusted = salary + raise. Here salary is your current pay for one period (annual, monthly or hourly, the result comes back in the same period) and inflation is the rate in percent, entered as 4.5 for 4.5%, not 0.045. Both results are shown as currency amounts in USD with two decimals. The salary must be greater than zero and the inflation rate cannot be negative; otherwise no result is produced. The calculation is a single-period one, so for several years of inflation you would run it once per year, feeding each result into the next.
Worked example
Take a salary of 50000 and an inflation rate of 4.5%. Step 1: raise = 50000 × 4.5 / 100 = 2250. Step 2: adjusted salary = 50000 + 2250 = 52250. The calculator shows an adjusted salary of $52,250.00 and a raise amount of $2,250.00. Any pay rise below that amount means your real purchasing power has fallen.
Common mistakes
- Typing the rate as a decimal (0.045) instead of a percentage (4.5), which gives a raise of a few cents on the dollar.
- Entering a negative inflation rate for deflation; the tool returns no result for values below zero.
- Mixing periods, for example a monthly salary with an annual inflation rate: the raise is then applied to the monthly figure, so compare it with a monthly pay rise.
- Treating the result as a merit raise. It only restores purchasing power; any increase on top is the real raise.
- Chaining years by adding the percentages (4% + 3% = 7%) instead of running the tool once per year, which compounds.
About this calculator
A cost-of-living adjustment (COLA) raises a salary or benefit by the rate of inflation so its real purchasing power stays flat: adjusted salary = current salary × (1 + inflation rate). The calculator also reports the raise amount in currency, since HR teams and employees usually think in dollars rather than percentages.
The U.S. Social Security Administration announces an annual COLA every October tied to the CPI-W, and many union contracts, pensions, and government salary scales use the identical formula. Employers use it during annual reviews to separate a true merit raise from the portion that simply keeps pace with rising prices.
