Will the 2027 Social Security COLA Affect Future Retirees?

The 2027 Social Security cost-of-living adjustment (COLA) is 3.6%.¹ For current beneficiaries, that means larger payments beginning in January 2027. But COLAs can also affect some people who have not started collecting Social Security yet. Once a worker becomes eligible for retirement benefits, generally at age 62, applicable COLAs can increase the primary insurance amount used to calculate their future benefit even if they delay claiming. Understanding when those adjustments begin can help future retirees see how inflation affects their eventual Social Security income.

A financial advisor can help you plan for Social Security and incorporate your benefits into a retirement income plan that is designed to meet your needs. Connect with an advisor today.

How Social Security Benefits Are Calculated

Social Security generally uses up to 35 years of a worker’s earnings to calculate retirement benefits. Earnings from earlier working years are indexed to changes in national average wages, and the highest indexed years are used to calculate average indexed monthly earnings (AIME).

The Social Security Administration then applies a progressive formula to AIME to determine the worker’s primary insurance amount (PIA). The PIA is the monthly benefit a worker would generally receive if they started retirement benefits at full retirement age. For workers who first become eligible for retirement benefits in 2027, the formula applies 90% to the first $1,340 of AIME, 32% to AIME between $1,340 and $8,077 and 15% to AIME above $8,077.

Your actual benefit also depends on when you decide to start collecting. If you claim at your full retirement age, you generally receive 100% of your PIA. Taking benefits as early as age 62 permanently reduces the monthly amount.

On the other hand, delaying past full retirement age increases your benefit through delayed retirement credits. For people born in 1943 or later, those credits generally increase the benefit by 8% for each full year of delay, with credits accruing monthly until age 70.

COLAs and delayed retirement credits are separate adjustments. COLAs help account for inflation once a worker reaches the age at which retirement benefits first become available, while delayed retirement credits reward someone for waiting beyond full retirement age to start collecting.

What Is COLA?

The Social Security cost-of-living adjustment (COLA) is designed to help preserve the purchasing power of Social Security and Supplemental Security Income (SSI) as consumer prices rise.

The annual adjustment is based on changes in the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). Specifically, Social Security compares the average CPI-W for July, August and September of the current year with the average for the same three months in the year of the last COLA.

If the CPI-W rises, Social Security benefits receive a corresponding percentage increase. The adjustment is automatic, so beneficiaries do not need to apply for it. If there is no qualifying increase in the CPI-W, Social Security does not provide a COLA for that year.

What Is the 2027 Social Security COLA?

The Social Security Administration announced a 3.6% COLA for 2027. Nearly 72 million Social Security beneficiaries will see the increase beginning with benefits payable in January 2027, while increased SSI payments begin on Dec. 31, 2026.

SSA estimates that the average retired-worker benefit will increase by about $75 per month, from roughly $2,095 before the COLA to approximately $2,170 afterward. Actual dollar increases will vary because the 3.6% adjustment is applied to each person’s benefit amount.

The 2027 COLA follows a 2.8% adjustment for 2026. It is based on the increase in the CPI-W from the third quarter of 2025 through the third quarter of 2026.

How Does COLA Impact Future Retirees?

You do not necessarily have to be collecting Social Security to benefit from COLAs. For retirement benefits, applicable COLAs can begin increasing a worker’s PIA after the worker reaches age 62, even if they decide to delay their claim.

For example, someone who turned 62 in 2026 but waits until 67 or 70 to claim can still have the 3.6% COLA for 2027 reflected in the PIA used to calculate their eventual benefit. Additional COLAs can compound on that amount in later years before the person starts collecting.

Timing matters, however. Someone who first turns 62 in 2027 does not receive the 3.6% COLA payable in January 2027. Social Security calculates that worker’s initial PIA using the benefit formula for people first eligible in 2027. The first COLA that could apply to that worker would generally be the adjustment effective in December 2027.

This distinction matters because Social Security uses two different mechanisms to account for changes in the economy. Earnings before retirement eligibility are generally indexed using changes in national average wages. After a worker becomes eligible for retirement benefits at 62, applicable COLAs can increase the PIA to help account for changes in consumer prices.

If claiming is delayed beyond full retirement age, the eventual monthly benefit can also increase through delayed retirement credits. Someone who waits until 70 may therefore benefit from both applicable COLAs and delayed retirement credits.

Those adjustments should not be viewed as a guaranteed increase in purchasing power, however. COLAs are based on the CPI-W, while an individual retiree’s spending may rise faster or slower depending on expenses such as housing, healthcare and insurance.

Bottom Line

The 2027 Social Security COLA is 3.6%, increasing benefits for current recipients beginning in January 2027. But COLAs can also matter to future retirees who have already reached age 62 but have not yet claimed Social Security. Applicable adjustments can increase their PIA while they wait to collect. Workers who have not yet reached 62 are affected differently because Social Security primarily uses wage indexing to adjust earlier earnings before retirement eligibility. Understanding where COLAs fit into the benefit formula can give you a clearer estimate of future income, but Social Security is still only one part of a broader retirement strategy.
