How COLA Calculator Works?
The COLA Calculator works by measuring the price-index change over the reference period and applying the same percentage to pay.
Enter current pay
Type the salary, wage or benefit amount.
Pick the index
Choose CPI-U, CPI-W or another index.
Pick the reference period
Choose 2 months, 2 quarters or 2 annual averages.
Read the COLA
The output shows the COLA rate, the dollar increase and the new pay.
COLA Calculator Formula
The COLA formula divides the current index value by the prior index value, subtracts one and applies the result to pay.
COLA = CPIcurrent ÷ CPIprior − 1
New Pay = Pay × (1 + COLA)
Variables
- CPIcurrent, CPIprior
- Index values for the 2 reference periods
Worked example
CPI-U annual averages of 304.702 (2023) and 313.689 (2024) give a COLA of 2.95%. A $58,000 salary rises to $59,711.
COLA Calculator Conversion Table
This table applies a 2.95% COLA to 6 pay levels.
