How Cost of Living Adjustments (COLA) Are Calculated
A Cost of Living Adjustment (COLA) scales wages, salaries, or retirement benefits to offset consumer inflation and preserve purchasing power. Depending on whether you know your exact COLA percentage, are computing it from Consumer Price Index (CPI-W / CPI-U) figures, or are comparing two cities, the calculator applies the following exact formulas:
2. CPI Index Formula: COLA % = ((Current CPI − Base CPI) / Base CPI) × 100
3. City Index Formula: Equivalent Pay = Current Pay × (Target City Index / Current City Index)
4. Multi-Year Compounded Pay (Year n) = Current Pay × (1 + (COLA % / 100))^n
Illustrative Example
Scenario (Illustrative): An employee earning $65,000.00/year (working 40 hours/week = 2,080 hours/year) receives a 3.2% Cost of Living Adjustment:
- Annual COLA Increase:
$65,000.00 × 0.032 = +$2,080.00 / year - New Annual Salary:
$65,000.00 + $2,080.00 = $67,080.00 / year - New Monthly Pay:
$67,080.00 ÷ 12 = $5,590.00 / month (+$173.33 / mo) - New Bi-Weekly Paycheck:
$67,080.00 ÷ 26 = $2,580.00 / paycheck (+$80.00) - New Hourly Wage:
$67,080.00 ÷ 2,080 = $32.25 / hour (+$1.00 / hr)

Frequently Asked Questions
How does the Social Security Administration (SSA) calculate its annual COLA?
The SSA compares the average Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) for the third quarter (July, August, and September) of the current year to the average CPI-W for the third quarter of the prior year. If there is an increase, the percentage change is rounded to the nearest tenth of one percent (0.1%). If prices fall or stay flat, the statutory COLA is 0.0%.
What is the difference between a COLA increase and a merit raise?
A Cost of Living Adjustment (COLA) is designed to maintain your existing purchasing power against inflation across the board, whereas a merit raise rewards individual job performance, skill growth, or promotion above inflation.
How do City Cost of Living Index numbers work when relocating?
Composite Cost of Living Indices benchmark the US national average at 100.0. If you move from a city with an index of 96.0 to a city with an index of 118.0, everyday expenses are ((118 − 96) / 96) = 22.92% higher, meaning an $85,000 salary requires $104,479 in the new city to maintain the same standard of living.
