What Is a Cost-of-Living Adjustment (COLA)?
Cost-of-Living Adjustment (COLA) — also called Cost-of-Living Adjustment, COLA
A Cost-of-Living Adjustment (COLA) is an increase in government benefits or wages designed to help keep pace with inflation. Each year, the Social Security Administration calculates whether Social Security and Supplemental Security Income (SSI) benefits should increase based on changes in inflation. Many other federal benefits, including VA disability compensation, VA pensions, federal retirement benefits, and Railroad Retirement benefits, also receive annual COLAs when authorized under federal law.

What is a Cost-of-Living Adjustment?
A Cost-of-Living Adjustment (COLA) helps protect the purchasing power of benefits as the cost of everyday goods and services changes over time.
Without periodic adjustments, inflation can reduce what a fixed monthly benefit can buy.
For many federal benefit programs, an annual COLA increases monthly payments when inflation rises. The adjustment helps beneficiaries continue to afford necessities such as housing, food, healthcare, transportation, and utilities.
Not every government benefit receives a COLA, and different programs may follow different rules.
How is the Social Security COLA calculated?
By law, the Social Security Administration bases the annual COLA on the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), which is produced by the U.S. Bureau of Labor Statistics.
Each year, SSA compares the average CPI-W for the third quarter (July, August, and September) with the average from the same period in the previous year that established a COLA.
If the index increases, eligible benefits generally increase by the same percentage.
If inflation does not increase under the statutory formula, there is no annual COLA.
Which government benefits receive a COLA?
Several major federal benefit programs receive annual Cost-of-Living Adjustments.
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
- Federal Civil Service Retirement System (CSRS) benefits
- Federal Employees Retirement System (FERS) benefits (under separate statutory rules)
Some state and local benefit programs also include inflation adjustments, but those rules vary.
Does every benefit increase by the same amount?
Not necessarily.
Although several federal programs receive COLAs tied to the Social Security adjustment, each program operates under its own governing laws.
For example:
- Social Security COLAs are determined using the CPI-W formula established by federal law.
- VA disability compensation typically receives the same percentage increase after Congress authorizes the annual adjustment.
- Federal retirement programs may calculate adjustments differently under their governing statutes.
Because each program follows its own rules, beneficiaries should review official announcements each year.
How often are COLAs announced?
The Social Security Administration typically announces the annual COLA in October after the Bureau of Labor Statistics publishes the relevant CPI-W data for the third quarter.
When a COLA is announced:
- Social Security retirement benefits generally increase beginning with January payments.
- SSI benefit increases generally begin with payments issued at the end of December for January benefits.
- Other federal programs implement COLAs according to their own statutory schedules.
What is the difference between COLA and inflation?
These terms are closely related but are not the same.
Inflation
Inflation measures how the prices of goods and services change over time.
Cost-of-Living Adjustment (COLA)
A COLA is the increase applied to certain benefits or wages in response to inflation.
Inflation is the economic measurement.
A COLA is the adjustment made because of that measurement.
Does Medicare affect Social Security COLAs?
Sometimes.
Many Social Security beneficiaries have their Medicare Part B premiums deducted directly from their monthly benefit payments.
Changes to Medicare premiums can affect the net amount beneficiaries receive, even after a COLA is applied.
Some beneficiaries are also protected by the Social Security "hold harmless" provision, which generally prevents increases in Medicare Part B premiums from reducing their Social Security benefit from one year to the next under certain circumstances.
Why this matters
Inflation affects nearly every household budget. Annual Cost-of-Living Adjustments help many government benefits maintain their purchasing power over time, making COLAs one of the most important annual announcements for retirees, veterans, people with disabilities, and others who rely on federal benefits.
Understanding how COLAs work can also help beneficiaries anticipate future benefit changes and better plan their finances.
In real life
- A retiree receiving Social Security learns in October that benefits will increase the following January because inflation increased during the year.
- A veteran receiving VA disability compensation receives an annual payment increase after Congress authorizes the same COLA percentage used for Social Security benefits.
- A beneficiary notices that although the annual COLA increased their gross Social Security benefit, changes in Medicare Part B premiums affected the amount deposited into their bank account.
