Social Security’s 3.6% Raise for 2027 May Actually Be Bad News - Here’s Why

Millions of retirees receiving Social Security senior benefits should see a bigger check in 2027 thanks to the cost-of-living adjustment (COLA). On October 14, the Social Security Administration (SSA) announced a 3.6% COLA for 2027. Though a boost in benefits may seem like a good thing, the bigger COLA signals a problem rather than a win.

Here's what you should know about the COLA and why it's not entirely a good thing.

The 2027 COLA

The 2027 3.6% COLA is the largest since 2023. It amounts to an increase of about $75 for the average retired-worker benefit. Social Security recipients should start seeing the increase in January 2027, and Supplemental Security Income (SSI) recipients should see the increase beginning on December 31, 2026.

The SSA calculates the COLA using Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) data. The SSA compares third-quarter CPI-W data to the data from the same period of the previous year. A higher COLA and an increase in that data mean that prices rose over the course of the year. Since the COLA is intended to ensure benefits keep up with inflation, a higher COLA doesn't mean that benefits gained ground, only that they've been increased to reflect the higher costs retirees have already been paying.

In 2026, volatility in the oil and gas markets resulted from the war with Iran. Those higher energy prices have been a primary driver of inflation.

The Medicare Part B premium increase

Several factors may erode the COLA, meaning retirees keep less of their extra benefits. The increase in Medicare Part B premiums is one such factor.

In 2026, the Medicare Part B premium was $202.90 per month, but the Medicare Trustees report projects that the premium might increase by $6.60 to $209.50 per month in 2027. Since Medicare Part B premiums are usually deducted from Social Security checks, the premium increase could eat into the boost provided by the COLA before retirees even receive their benefits.

The Medicare Part D premium increase

Additionally, Medicare Part D premiums may increase in 2027. The base beneficiary premium is increasing from $38.99 to $41.33 per month in 2027. That premium serves as a base amount that's used to calculate the premium of different plans.

It's possible that the premiums for individual plans could increase more in 2027 as the Trump Administration ends the Medicare Part D Premium Stabilization Demonstration on January 1, 2027. That program was designed to help stabilize Part D premiums, preventing insurers from increasing plan prices too much in a single year. An American Action Forum analysis found that average monthly premiums for standalone PDPs might increase by approximately 44% in 2027.

The potential flaw with the COLA calculation

The Senior Citizens League (TSCL) and other advocates are pushing for a change to the COLA calculation. The CPI-W measures spending habits among working households, but it doesn't specifically reflect retirees' expenses. Groups like TSCL argue that the CPI-W doesn't reflect the costs that retirees face, particularly since older adults tend to spend more of their income on healthcare.

When major expenses like healthcare are underweighted, benefits may lose their buying power, and retirees may feel those effects. A 2026 AARP survey found 76% of adults disagreed that a projected 3.5% COLA increase in 2027 would keep up with rising prices.

Replacing the CPI-W with the Consumer Price Index for the Elderly (CPI-E) is a potential solution. The CPI-E is an experimental index that reflects the spending patterns of Americans aged 62 and older, and it may better account for the cost of expenses like healthcare and housing.

The delay in the COLA

Since the COLA is calculated on third-quarter data and doesn't go into effect until the following year, the benefit increase lags behind the inflation that prompts that increase. If inflation climbs early in the calendar year, retirees may have to pay higher costs for an entire year before their benefits are increased to reflect that cost. That delay may create significant financial strain, especially for retirees living on fixed incomes with few financial resources outside of their Social Security benefits.

The broader signal of another COLA

The 2027 COLA marks a sixth straight year of COLA increases at or above 2.5%. Such a run hasn't been seen since the late 1990s, and it's driven by sustained inflation. The run of COLA increases means that retirees have felt the strain of inflation for years, and it means budgets may already be stretched thin.

Bottom line

Your COLA notice provides exact dates and dollar amounts of your new benefit for 2027. Beginning in late November, you may find your notice online through your my Social Security account's Message Center. To receive your notice, you'll need to enroll in paperless notices. The SSA sends paper notices by mail in December to individuals who haven't enrolled in paperless notices.

Once you know your 2027 benefit amount, it may be a good idea to revisit your retirement plan and your budget to adjust for that extra income.
