Two separate estimates for Social Security’s 2027 raise just came in lower than they were a month ago. One now points to a 3.6 percent cost of living adjustment, down from 3.8 percent in June and July. Another lands at 3.5 percent, down from 3.6 percent the week before.
For a retired worker collecting the average monthly check of about $2,084, that difference works out to roughly two dollars. It’s a small move on its own, but it’s the first real signal of where your 2027 raise is heading before the official number arrives on October 14.
If you were hoping for a bigger bump to cover rising grocery, insurance, and housing bills, a lower estimate is a letdown at first glance. There’s a real case that it isn’t bad news, and it comes down to what’s actually driving the smaller number.
The figure that matters most right now isn’t 3.5 or 3.6 percent. It’s July’s inflation reading, the first of three months that will decide what actually lands in your account come January.

What’s behind the new prediction
Advocacy groups that track Social Security run their own models each month off the same government inflation data used to set the real number. Neither estimate is official, just an educated guess that gets more accurate as the year goes on.
Both estimates fell in August because of a single report. On August 12, the government’s July inflation reading came in at 3.4 percent year over year, the specific figure used to calculate the annual raise, cooler than what forecasters had built into their June and July estimates.
That single data point pulled both predictions down. One model, which factors in the CPI-W alongside the Federal Reserve’s interest rate and the national unemployment rate, dropped from 3.8 percent to 3.6 percent the same week a separate estimate moved from 3.6 percent to 3.5 percent. Two more inflation readings, for August and September, still have to come in before the real number is locked.
What a 3.5 to 3.6 percent raise means for your check
The average retired worker was pulling in about $2,084 a month as of June 2026. A 3.6 percent raise adds roughly $75, landing around $2,159. A 3.5 percent raise adds about $73, landing in almost the same place.
Widen the lens to every type of beneficiary, including spouses, survivors, and people on disability, and the average check is lower, just under $1,938 a month. A 3.6 percent COLA would raise that broader average by about $70, to just over $2,007.
For comparison, the COLA that took effect in January 2026 was 2.8 percent, and it added about $56 a month to the average retired worker’s check, taking it from $2,015 to $2,071. Whatever lands for 2027, retirees are looking at a bigger raise in real dollars than they got this year, even under the lower estimate. After a run of relatively modest increases, 2027 is shaping up to be the largest cost of living adjustment since 2023.
Why a smaller forecast isn’t automatically bad news
It’s tempting to treat a falling prediction as pure bad news. A cost of living adjustment only exists because prices went up. A bigger COLA means the CPI-W climbed further over the past year, which means you paid more for groceries, rent, and prescriptions to get there. A smaller COLA usually means prices rose more slowly, so the adjustment needed to keep up with them is smaller too.
Put another way, a 3.5 percent raise on top of slower price growth can leave you in roughly the same spot, financially, as a bigger raise chasing faster inflation. Neither one makes you richer. The COLA is built to keep your buying power flat, not to grow it.
None of this erases the fact that seniors have lost ground over time. Social Security’s buying power has fallen by about 13.7 percent since 2010, largely because the CPI-W tracks the spending habits of working adults in cities better than it tracks a retiree’s budget, which leans more heavily on housing and medical care. A cooler forecast this year doesn’t undo that shortfall.
What eats into the raise before it reaches your bank account
Whatever the final COLA turns out to be, it won’t all show up as extra spending money. Most Medicare enrollees have their Part B premium deducted straight from their Social Security check, and that premium is going up too.
The standard 2027 Part B premium is projected at $209.50 a month, a $6.60 increase over the confirmed 2026 premium of $202.90. The Part B deductible is projected to climb too, from $283 to $292. Both figures are still estimates, and the official numbers typically get confirmed each November.
Run a 3.6 percent COLA against a $6.60 Part B increase, and nearly 9 percent of your raise goes straight to Medicare before you see a dime of it. That’s not enough to wipe out the increase, but it’s a reminder that the headline percentage and the actual bump in your bank account are two different things. Anyone budgeting around next year’s raise should plan around the after Medicare number, not the announced one.
The number can still move before October
Forecasts built in August aren’t locked in. One tracked estimate has already swung from 2.8 percent in January to as high as 3.9 percent in April before settling into the current range, and two more inflation readings, for August and September, are still outstanding. Energy prices are one of the biggest wild cards. Oil was running about 24 percent above year ago levels in early August, and fuel costs ripple through the price of nearly everything that gets shipped or manufactured, which can push the CPI-W higher or lower depending on where prices head next.
If inflation keeps cooling through September, the final COLA could land below both current estimates. If oil prices or another shock pushes prices back up, it could land above them. The official number will be confirmed on October 14, based on the average CPI-W for the full third quarter compared with the same months in 2025.
What to do with the numbers now
Budget around the lower end of the current range, not the higher one. A 3.5 percent estimate is the more conservative number on the table right now, and it’s easier to be pleasantly surprised by a bigger raise than to come up short after counting on one.
Factor in the Medicare Part B increase separately from the COLA itself, since that portion of the raise won’t be available to spend. And once your official COLA notice arrives by mail or through your personal my Social Security account in December, that figure, not any of the estimates floating around right now, is the one to build your 2027 budget on.
This is also a good stretch to review your Medicare coverage. Open enrollment runs from October 15 to December 7, right after the official COLA lands, giving you a short window to compare Medicare Advantage and Part D plans before your new premium and benefit amount both take effect in January.
