The Social Security COLA was supposed to be higher this year, with independent analyst Mary Johnson projecting a 2027 COLA as high as 4.7%. It would have been one of the largest raises in decades, but after June inflation cooled sharply, she lowered her COLA forecast to 3.7%.
It lines up with the Senior Citizens League’s projected 3.8% estimate, but nothing is official until the October announcement. Both estimates exceed the 2.8% COLA boost in 2026, which is helpful for people who are living on just Social Security. Even better, COLA is projected to rise by a larger percentage than the Medicare Part B premium for the first time since 2023.

What is COLA?
COLA, also known as the cost-of-living adjustment, is an annual boost that is applied to Social Security benefits. It’s designed to help retirees navigate rising costs.
The annual increase is tied to inflation. Higher inflation would translate into a higher COLA growth rate. The 2025 COLA was 2.5%, and the 2026 COLA was 2.8%. Even the lowered forecast of a 3.7% 2027 COLA is higher than the previous two years.

Why COLA growth is set to outpace Medicare Part B in 2027
Medicare does not rely on inflation when calculating annual premium hikes. The Centers for Medicare & Medicaid Services calculate the expected medical costs and utilization rates for older beneficiaries, and Medicare Part B premiums must cover 25% of these projected average costs per capita, with the government covering the remaining costs.
Medicare Part B premium dollar gains are never allowed to exceed Social Security COLA gains. That way, retirees never end up with reduced monthly Social Security checks. However, Medicare Part B premium growth could outpace COLA growth. That scenario has played out from 2024 to 2026, with 2027 expected to be the year where COLA grows at a faster rate.
The purchasing power of Social Security benefits is still down
Although Social Security benefits get an extra boost from COLA, that doesn’t mean your benefits are keeping up with rising living costs. The formula follows the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), which means it does not reflect rising healthcare and housing costs that seniors often face.
It’s important to monitor how your expenses climb each year. A 3.7% COLA increase in 2027 does not necessarily mean that your personal expenses only increased by 3.7% next year.

The Middle East conflict can still push inflation in the third quarter
Although recent inflation readings have caused some analysts to project a lower 2027 COLA, that could still change in the third quarter. The ongoing conflict in the Middle East would be decisive in upcoming inflation readings. Any oil supply shortages would increase inflation, but if the oil trade has limited disruption, it can push inflation and COLA lower.
Notably, Q4 inflation readings would have no impact on 2027 COLA. If an oil shortage becomes more meaningful in October, November, or December, retirees would not see that in their COLA until 2028.
Can COLA ever be flat year-over-year?
It’s rare, but COLA could be flat year-over-year. Any economic cycles that feature zero inflation or some deflation would result in Social Security checks staying the same. The U.S. recorded multiple years of 0% COLA growth rates right after the Great Recession.
The 2016 COLA was the last time that the metric had a 0% year-over-year growth rate. Falling energy costs were one of the main contributors to the flat COLA that year.
Don’t rely on a specific COLA figure
Experts could only predict the COLA figure until Social Security releases the exact percentage in October. In just a few months, the projected COLA growth rate was cut from 4.7% to 3.7%, showing that a lot can change in a short amount of time.
However, it’s reasonable to expect a raise that exceeds the growth rate of Medicare Part B premiums. That development lets people keep more of their benefits and ensure higher payouts.

Budget conservatively
Even if COLA ends up being 3.7% in 2027, it does not mean that your purchasing power would go up by 3.7%. Medicare Part B premiums would erode some of the COLA amount, and elevated costs in healthcare, housing, and groceries would also affect your purchasing power.
Any COLA gains are helpful, but you should still budget conservatively. Overextending your budget could lead to uncomfortable decisions later in the year. It’s better to give yourself a margin of safety, so you have enough room in your finances to navigate higher living costs.
Bottom line
Social Security recipients benefit from a higher COLA, especially when the COLA grows faster than Medicare Part B premiums. However, you shouldn’t rely on projections when determining your 2027 budget. It’s best to wait for Social Security to release the official number in October.
Retirees may also want to look into ways to make extra money to keep up with living expenses. While a 40-hour workweek may be a bit much for retirees, carving out 10-20 hours per week for a side hustle could be a good move to supplement annual COLA boosts.
