Cost of living raise calculator: find the COLA raise needed to keep up with inflation and see whether your actual raise beats, matches, or trails CPI.
Cost of Living Raise Formula
The inflation-matching adjustment modeled here changes gross pay by the entered price-change percentage. An official COLA may follow different contractual rules:
COLA = P * i / 100 Pnew = P + COLA
To judge a raise you were actually offered, the real (inflation-adjusted) change is:
real = (1 + a/100) / (1 + i/100) - 1
Variables:
- COLA is the cost of living raise in dollars and Pnew is the pay that keeps up with inflation
- P is your current pay (hourly, weekly, monthly, or annual — results use the same period)
- i is the inflation or announced COLA percentage, typically the 12-month change in the Consumer Price Index (CPI)
- a is the raise percentage you were offered, and real is your true change in buying power after inflation
Enter your pay and the inflation rate to see the raise required just to break even. Open the comparison option to enter the raise you were offered: the calculator shows your pay after that raise, the real percentage change in buying power, and the dollar gap between your raise and inflation, so you know whether you are truly ahead or behind.
COLA Raise Needed by Salary and Inflation Rate
The raise needed on common salaries to keep up with different inflation rates.
| Current salary | 2% inflation | 3% inflation | 4% inflation | 5% inflation |
|---|---|---|---|---|
| $40,000 | $800 | $1,200 | $1,600 | $2,000 |
| $50,000 | $1,000 | $1,500 | $2,000 | $2,500 |
| $60,000 | $1,200 | $1,800 | $2,400 | $3,000 |
| $75,000 | $1,500 | $2,250 | $3,000 | $3,750 |
| $100,000 | $2,000 | $3,000 | $4,000 | $5,000 |
| $150,000 | $3,000 | $4,500 | $6,000 | $7,500 |
Example Problems
Example 1: You earn $60,000 and inflation was 3% over the past year.
COLA = 60,000 * 0.03 = $1,800, so you need $61,800 to keep the same buying power.
Example 2: You were offered a 2.5% raise while inflation ran 4%.
real = 1.025 / 1.04 - 1 = -0.0144, about a 1.44% real pay cut. On $60,000, your raise is $1,500 but inflation-matching pay is $62,400, leaving you $900 behind for the year.
Frequently Asked Questions
What inflation number should I use?
A common benchmark is the 12-month CPI-U change published by the Bureau of Labor Statistics. Social Security uses a specific CPI-W comparison; employers may use different indexes and rules. Enter the price-change percentage for the period you want to compare. Enter an announced employer raise in the offered-change field to compare it with that inflation benchmark.
Is a cost of living raise the same as a merit raise?
A COLA generally addresses price changes, while a merit increase rewards performance. An employer can combine adjustments. Comparing total pay change with inflation measures purchasing-power change; it does not identify how much of the raise was awarded for merit.
Are employers required to give cost of living raises?
Requirements depend on the applicable contract, policy and law. This calculator does not determine a legal entitlement or an official benefit adjustment. Check the rules that apply to your employment or benefits; the result estimates the gross pay needed to match the entered price change.
