How CPI-W Salary Calculator Works?
The CPI-W Salary Calculator works by applying the ratio of 2 CPI-W values, or 2 quarterly averages, to the salary.
Enter the salary
Type the salary or benefit amount.
Pick months or quarters
Choose single months, or third-quarter averages to follow the SSA method.
Load CPI-W values
The calculator uses not seasonally adjusted CPI-W data.
Read the result
The output shows the adjusted amount and the percentage change, rounded to 0.1% in SSA mode.
CPI-W Salary Calculator Formula
The CPI-W Salary formula multiplies the salary by the ratio of the target CPI-W value to the starting CPI-W value.
Adjusted = Salary × (CPI-Wtarget ÷ CPI-Wstart)
COLA % = round[(Q3 avgthis year ÷ Q3 avglast year − 1) × 100, 1 decimal]
Variables
- CPI-W
- Index for urban wage earners and clerical workers (1982–84 = 100)
- Q3 avg
- Average of July, August and September
Worked example
A Q3 average of 291.901 against 268.421 a year earlier gives a CPI-W change of 8.75%, rounded to 8.7%, the Social Security COLA paid from January 2023. A $48,000 yearly benefit rises to $52,176.

This table shows third-quarter CPI-W averages and the resulting adjustment for a $48,000 yearly amount.

Quarterly averages computed from BLS CPI-W monthly values (series CWUR0000SA0). The adjusted amount applies each year's COLA to the base amount only, not chained.
What is CPI-W Salary Calculator?
The CPI-W Salary Calculator is a tool that adjusts pay with the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). CPI-W covers households that earn at least half of their income from clerical or hourly jobs, about 30% of the U.S. population.
The Social Security Administration (SSA) uses CPI-W to set the yearly cost-of-living adjustment (COLA) for benefits. The SSA compares the July–September average with the same quarter a year earlier.
