The Social Security Administration will announce the official 2027 COLA in mid-October 2026. Until then, here's what the latest projections show.
Quick answer: The 2027 Social Security COLA is currently projected at 3.7% to 3.8%, according to the Senior Citizens League and independent analyst Mary Johnson, down from earlier 2026 estimates as high as 4.7%. On the average benefit of $2,084 a month, a 3.8% COLA would add about $79, but a projected Medicare Part B premium increase of roughly $15.70 a month would offset part of that, leaving a net increase of about $63 to $64 a month. The official number is announced by the Social Security Administration in mid-October 2026.
If you get a Social Security check, you have probably heard some version of a number floating around for next year's raise. That number has moved quite a bit in the past few months, and it just moved again. Here's an honest look at where the estimate actually stands right now and, just as important, what tends to quietly eat into that raise before it ever hits your bank account.
What is the 2027 Social Security COLA estimate?
The 2027 Social Security COLA is currently projected between 3.7% and 3.8%. Two of the most closely watched independent forecasters both cooled their projections in mid-July. The Senior Citizens League held its estimate at 3.8%, unchanged from June but down from an earlier 3.9% reading in April. Independent analyst Mary Johnson made a bigger move, cutting her estimate from 4.7% just one month earlier down to 3.7%.
Even after this pullback, both current estimates still land a full percentage point above this year's 2.8% adjustment. So while the raise looks smaller than it did in the spring, it would still be a meaningfully bigger bump than what retirees got this January.
Why did the 2027 COLA estimate drop?
The 2027 COLA estimate dropped because June's inflation report showed energy prices cooling after a spring spike tied to geopolitical conflict. Earlier in the year, forecasts had climbed as high as 4.2% to 4.7%, driven largely by a spike in energy prices tied to geopolitical conflict. Gas and energy costs were running more than 20% higher year over year at one point this spring, and that pushed inflation readings up sharply. June's inflation report showed energy prices cooling off, which brought the COLA estimate back down with it.
None of this is final. The actual 2027 COLA is calculated using average inflation data from July, August, and September, so there are still two full months of data left to come in before the Social Security Administration makes its official announcement in October. Estimates could tick up or down again before then.
How does the Medicare Part B premium affect the 2027 COLA?
The rising Medicare Part B premium offsets part of the 2027 COLA because the premium is typically deducted directly from a retiree's Social Security check before it's deposited. Whatever the final COLA turns out to be, it doesn't all show up as extra spending money, because Medicare Part B premiums typically rise at the same time, and for most retirees, that premium comes straight out of their Social Security check before it's deposited.
The 2027 numbers so far: the standard Medicare Part B premium is projected to rise from $202.90 a month in 2026 to around $218.60 in 2027, an increase of roughly $15.70 a month. That comes directly off the top of whatever COLA increase you receive.
This is why a lot of retirees end up disappointed by their new check even after a headline-grabbing COLA announcement. The raise and the premium increase are two separate numbers moving in opposite directions, and most coverage only reports the first one.
What this actually looks like in dollars
The average Social Security retirement benefit is currently about $2,084 a month. Here's roughly how a 3.8% COLA would play out once the Medicare premium increase is factored in.
That's still a real increase, just a noticeably smaller one than the headline percentage suggests. If you're on a higher benefit, the same math applies proportionally, and if you're subject to income-related Medicare surcharges, the premium side of that equation gets bigger too.
What to do while you wait for the official number
- Don't build next year's budget around the headline percentage. Use the net figure after the Medicare premium, not the raw COLA number, when you're planning.
- Watch your Medicare Annual Enrollment window this fall. It runs October 15 through December 7 and lands right around the same time as the official COLA announcement, so it's worth reviewing both at once.
- Check whether a bigger benefit changes your tax picture. If your combined income is near a taxation threshold for Social Security benefits, even a modest raise can push more of your benefit into taxable territory.
- Revisit your withdrawal strategy. If Social Security is covering a bit more of your monthly needs next year, that may be a good time to reassess how much you're pulling from savings or investment accounts.
The official 2027 COLA won't be locked in until October, and the estimate could still shift with two more months of inflation data on the way. But the pattern is already clear: whatever the final number turns out to be, it's worth looking at the number that actually lands in your account, not just the one in the headline.
