What Is the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W)?
Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) — also called Consumer Price Index for Urban Wage Earners and Clerical Workers, CPI-W
The Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) is an inflation index published by the U.S. Bureau of Labor Statistics (BLS). It measures changes over time in the prices paid by urban wage earners and clerical workers for a representative basket of goods and services. Under federal law, the Social Security Administration uses the CPI-W to calculate annual Cost-of-Living Adjustments (COLAs) for Social Security benefits. The same annual COLA percentage is generally applied to VA disability compensation and several other federal benefit programs.

What is the CPI-W?
The Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) is one of several inflation measures produced by the Bureau of Labor Statistics.
The index tracks changes in the prices consumers pay for everyday goods and services such as:
- Housing
- Food
- Transportation
- Medical care
- Apparel
- Recreation
- Education
- Utilities
Rather than measuring the price of one product, the CPI-W measures the overall change in prices across hundreds of goods and services purchased by a defined population.
Who does the CPI-W represent?
The CPI-W reflects spending patterns for households whose primary source of income comes from clerical or wage-paying occupations.
According to the Bureau of Labor Statistics, the CPI-W covers households that meet specific employment requirements and represents a subset of the broader urban population.
Because spending patterns differ among retirees, workers, and other groups, the BLS publishes several Consumer Price Indexes for different analytical purposes.
How is the CPI-W calculated?
The Bureau of Labor Statistics collects hundreds of thousands of price observations throughout the United States each month.
These prices are gathered from:
- Retail stores
- Service providers
- Rental housing units
- Medical providers
- Other businesses
The BLS combines this information using a standardized methodology to estimate how prices have changed over time for the goods and services typically purchased by CPI-W households.
The index is published monthly.
Why does Social Security use the CPI-W?
Federal law requires the Social Security Administration to use the CPI-W when calculating the annual Cost-of-Living Adjustment (COLA).
Each year, SSA compares the average CPI-W for the third quarter (July, August, and September) with the average from the last year that produced a COLA.
If prices increased, Social Security benefits generally increase by the same percentage beginning the following year.
If prices do not increase under the statutory formula, there is no COLA.
SSA does not choose a different inflation measure each year—the formula is established by law.
Which benefits are affected by the CPI-W?
Because the CPI-W is used to calculate the Social Security COLA, it affects several federal benefit programs.
These include:
- Social Security retirement benefits
- Social Security Disability Insurance (SSDI)
- Supplemental Security Income (SSI)
- Veterans Affairs (VA) disability compensation
- VA pension benefits
- Railroad Retirement benefits
Some additional federal retirement programs also reference the Social Security COLA, although they may follow separate statutory rules.
CPI-W vs. CPI-U
The CPI-W and the Consumer Price Index for All Urban Consumers (CPI-U) are both published by the Bureau of Labor Statistics.
The difference is the population each index represents.
CPI-W
Measures inflation experienced by urban wage earners and clerical workers.
CPI-U
Measures inflation experienced by a much broader urban population and is the BLS''s most widely cited inflation measure.
Although the CPI-U is often used in economic reporting, federal law requires Social Security COLAs to be calculated using the CPI-W.
CPI-W vs. CPI-E
Another commonly discussed inflation measure is the Consumer Price Index for Americans 62 Years of Age and Older (CPI-E).
CPI-W
- Used by law to calculate Social Security COLAs.
- Official index for annual benefit adjustments.
CPI-E
- Experimental index produced by the Bureau of Labor Statistics.
- Designed to reflect spending patterns of older Americans.
- Not currently used to calculate Social Security or VA COLAs.
Some policymakers have proposed replacing the CPI-W with the CPI-E, but no such change has been enacted.
Why this matters
Every October, millions of Americans watch for the Social Security COLA announcement because it directly affects monthly benefit payments for the following year.
Understanding the CPI-W helps explain why benefits increase in some years, remain unchanged in others, and how inflation affects government programs that provide retirement, disability, and veterans benefits.
In real life
- A retiree hears that inflation increased during the summer and understands that SSA will use the third-quarter CPI-W data to determine next year's Social Security COLA.
- A veteran receiving disability compensation learns that the annual VA payment increase generally mirrors the Social Security COLA calculated from the CPI-W.
- A news report announces the latest monthly CPI-W figures, prompting beneficiaries to estimate whether an annual COLA may be announced in October.

Frequently asked questions about Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W)
What is the CPI-W?+
The Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) is an inflation index published by the Bureau of Labor Statistics that measures changes in prices paid by urban wage earners and clerical workers.
Why is the CPI-W important?+
The Social Security Administration uses the CPI-W to calculate annual Cost-of-Living Adjustments (COLAs) for Social Security benefits under federal law.
Is the CPI-W the same as inflation?+
Not exactly. Inflation is the overall increase in prices over time. The CPI-W is one of the indexes used to measure inflation.
Does the CPI-W affect VA disability compensation?+
Yes. Although VA disability compensation follows its own statutory process, the annual increase generally matches the Social Security COLA, which is calculated using the CPI-W.
What's the difference between the CPI-W and CPI-U?+
The CPI-W measures inflation for urban wage earners and clerical workers, while the CPI-U measures inflation for a broader urban population.
Does the government use the CPI-E instead of the CPI-W?+
No. Although the Bureau of Labor Statistics publishes the experimental CPI-E, current federal law requires Social Security COLAs to be calculated using the CPI-W.
