Retirees waiting on next year’s raise are getting used to a moving target. Since the spring, the projected 2027 cost-of-living adjustment has swung from nearly 5% down to somewhere in the mid-3% range, and it’s still not final. The Social Security Administration won’t confirm the real number until October 14, 2026, but the direction of travel is clear enough: smaller than early forecasts suggested, still the biggest raise in a few years, and arriving alongside a separate, unrelated milestone, the last stretch of a 44-year-old law that finally pushes the full retirement age to 67 for good.
Here’s where things stand, and what it actually means for the check that lands in your account.
Why the COLA Estimate Keeps Shrinking
Every month, a handful of analysts run their own numbers on where the cost-of-living adjustment will land, and every month this summer, the number came down a little.
The Senior Citizens League opened 2027 forecasting a hefty increase, then walked it back to 3.9% in May, 3.8% in June and July, and 3.6% by August, as inflation tied to a spring energy shock eased faster than expected. AARP’s public policy arm has landed in a similar place, trimming its estimate to 3.5%. Independent policy analyst Mary Johnson has been the most volatile of the bunch, swinging from a 4.7% June forecast down to roughly 3.4% once July’s inflation data came in cooler than the months before it.
None of these numbers are official. The COLA is calculated from the average CPI-W, the Consumer Price Index for Urban Wage Earners and Clerical Workers, across the third quarter of the year, meaning July, August, and September all feed into it. Only July’s data was in when most of these estimates were published, so the final figure could still move in either direction once August and September numbers are folded in.
Even a middling 3.5% or 3.6% raise would be the largest COLA since 2023, when benefits jumped 8.7% during the worst of the inflation spike. It would also be roughly half a point above the 2026 COLA, which came in at 2.8%. On the average retired-worker benefit of a little over $2,000 a month, a 3.6% adjustment works out to about $75 extra a month, or somewhere around $900 over the year. A 3.5% bump comes out closer to $73 a month.
It’s worth sitting with how modest that actually is. The Senior Citizens League’s own cost-of-living surveys put the average older household’s monthly expenses closer to $2,700, well above what a typical benefit check covers even with the raise. And a chunk of the increase tends to disappear before it ever reaches a bank account, because of what comes next.
Medicare Premiums Usually Eat Part of the Raise
Most retirees have their Medicare Part B premium deducted straight out of their Social Security check, and that premium rises most years too. In 2026, Part B jumped by $17.90 a month. If 2027 brings a similar increase, it could quietly absorb close to a quarter of whatever COLA retirees are counting on, before the money even shows up.
There’s a longer-term version of this squeeze as well. A recent Medicare trustees projection estimated the standard Part B premium could climb to roughly $360 a month by 2035, up nearly 78% from where it sits in 2026. None of that is set in stone, but it’s the backdrop against which every COLA announcement gets read: the headline number rarely tells the whole story of what retirees keep.
Full Retirement Age Finally Stops Climbing
Separate from the COLA fight, 2027 closes out a much longer story. Under the 1983 Social Security amendments, full retirement age has been creeping upward in two-month increments since the 1955 birth cohort first felt it in 2021. That climb ends with people born in 1960, who reach 67, a flat, final 67, starting in 2027. Anyone born after 1960 stays at 67 too, unless Congress changes the law again, which isn’t currently on the table.
It’s a narrower change than it sounds. Full retirement age isn’t the age you’re allowed to stop working, and it has nothing to do with Medicare, which still kicks in at 65 regardless of your FRA. What it actually controls is when you get 100% of your primary insurance amount, the benefit calculated from your earnings history. Claim before that age and the check is permanently reduced, by as much as 30% at age 62. Wait past it, up to age 70, and the check keeps growing.
Geoffrey Schmidt, a CPA who runs the retirement education site Holy Schmidt, put it plainly to Yahoo Finance: the age has “finished its long, slow climb to 67,” and under current law it doesn’t go any higher. That’s arguably the most useful thing anyone planning a 2027 retirement can hear, since a lot of people still assume the goalposts keep moving.
The Numbers Working in the Background
A few other figures are due for their annual adjustment alongside the COLA, and they matter more than they get credit for if you’re still working while collecting, or still paying into the system.
The taxable maximum. The ceiling on earnings subject to the 6.2% Social Security payroll tax sat at $184,500 in 2026. Based on the latest Trustees Report projections, it’s expected to rise to around $190,200 in 2027, meaning higher earners could pay Social Security tax on roughly $5,700 more income than they did the year before.
The earnings test. If you claim benefits before reaching full retirement age and keep working, the SSA withholds part of your check once your earnings cross a certain line. That lower threshold was $24,480 in 2026 and is projected to rise to somewhere near $25,200 in 2027. For people who turn 67 sometime during the year, a separate and much higher threshold applies, projected to move from about $65,160 up to roughly $67,200. Cross either line and the SSA holds back $1 for every $2 (or $3, in the year you hit FRA) earned above it. It’s not a permanent loss, either: the agency recalculates your benefit upward once you reach full retirement age to credit back the withheld months, which is a detail a lot of people never hear until they’re the ones losing checks.
Taxation of benefits. This one hasn’t moved in decades, and that’s the actual problem. Up to 85% of Social Security income becomes federally taxable once combined income, adjusted gross income, plus tax-exempt interest, plus half your benefit, passes $34,000 for single filers or $44,000 for joint filers, with a lower 50% threshold kicking in at $25,000 and $32,000. Those thresholds were set in 1983 and 1993 and were never indexed to inflation. Every COLA quietly pushes more retirees across a line that hasn’t moved in over 40 years, which means the “raise” can come with a slightly bigger tax bill attached, even for households that were nowhere near the taxable range a decade ago.
No Cuts, But No Guarantees Either
For all the anxiety that circulates every fall about Social Security’s finances, there’s no benefit cut baked into 2027 under current law. The program’s trust fund pressures are a real, separate, longer-horizon issue, not something that shows up in next year’s check. Schmidt’s advice to retirees bracing for bad news was to set aside the scarier headlines; the mechanics of 2027 are a COLA adjustment, a final retirement-age step, and some routine wage-base indexing, not a restructuring.
What to Actually Do With This Information
If you’re within a few years of claiming, the retirement-age change is the one piece of this that’s fully locked in, it applies the moment you were born in 1960 or later, regardless of what year you file. The COLA, wage base, and earnings-test figures are still projections until the SSA’s October 14 announcement, so it’s worth treating any number you see between now and then as a planning estimate rather than a fact to bank on.
The practical move is the boring one: don’t restructure a retirement budget around a COLA forecast that’s changed four times since May. Wait for the October announcement, factor in a likely Medicare Part B increase before celebrating the raise on paper, and if you’re claiming early while still working, run the earnings-test math before you assume the withheld amount is gone for good. It isn’t — but plenty of retirees find that out later than they’d like.
