2027 Social Security COLA Estimates Keep Falling: Where Projections Stand Now
Social Security analysts have revised their 2027 COLA forecast downward multiple times since spring, and the latest estimates are now well below that early 4.7% peak. Here's where projections stand heading into the final stretch before October's official announcement.

If there’s one piece of Social Security news seniors track closely each year, it’s the upcoming cost-of-living adjustment, or COLA. The raise determines how much more recipients will collect starting in January, and for the tens of millions of Americans who depend heavily on those monthly checks, the number matters enormously.
COLAs exist to help Social Security benefits keep pace with inflation. Without them, fixed payments would steadily lose purchasing power as prices rise.
Social Security benefits received a 2.8% COLA for 2026, which lifted the average retired worker’s monthly benefit from about $2,015 to roughly $2,071. But inflation has run hotter than 2.8% for much of the year, putting real financial pressure on retirees trying to stretch those checks.
For a while, that same inflation seemed to be building the case for a sizable 2027 COLA. In June, independent Social Security and Medicare analyst Mary Johnson put her estimate at 4.7%, citing a particularly sharp inflation report for May. That figure circulated widely and gave many seniors reason for cautious optimism.
Since then, inflation has cooled, and the estimates have followed it down.
What the latest estimates say
When June inflation data came in, Johnson trimmed her forecast from 4.7% to 3.7%. Then July’s Consumer Price Index report, released in mid-August, prompted another round of cuts. Johnson now estimates the 2027 COLA at 3.4%, down from her prior 3.7% projection. The Senior Citizens League, a nonpartisan advocacy group for older Americans, has similarly revised its estimate to 3.6%, down from the 3.8% it projected in both June and July. AARP, drawing on the same underlying government data, places its current projection at 3.5%.
Put together, the range of credible estimates now clusters between 3.4% and 3.6%, all well short of the 4.7% headline that generated so much attention earlier in the summer. Even so, a COLA in that range would represent the largest annual benefit increase since 2023, and it would land meaningfully above the program’s long-term average of around 2.6%.
The Social Security Administration is scheduled to announce the official 2027 COLA on October 14, 2026, after September’s inflation figures are released. A lot can still shift between now and then.
How to plan before the final number arrives
Social Security COLAs are calculated using third-quarter inflation data, specifically the CPI-W readings for July, August, and September. Because August and September data are still pending, no one has a definitive number yet. That uncertainty doesn’t have to be paralyzing, though. There are practical steps to build a 2027 budget right now.
Start by anchoring to a conservative estimate. The current consensus points to a raise somewhere in the 3.4% to 3.6% range, but building your initial budget around a 2.8% raise (matching what arrived in 2026) creates a useful floor. If the official number comes in higher, you’ll simply have more flexibility than you planned for.
On Medicare, the picture has gotten somewhat clearer than the article’s original writing suggested. The 2026 Medicare Trustees Report projects the standard Part B premium will rise from $202.90 in 2026 to roughly $209.50 in 2027, an increase of about $6.60 per month. That is far more modest than the nearly 10% jump seniors absorbed between 2025 and 2026. Private forecasters think the final CMS figure could land a bit higher, perhaps in the $216 to $219 range, so budgeting for around $10 to $15 more per month than your current Part B premium is a reasonable cushion. The official 2027 premium will be confirmed in November 2026.
From there, lay your projected Social Security income alongside your expected expenses and any other income sources, such as IRA withdrawals, a pension, or dividends. If the numbers are tight, the options are familiar: trim discretionary spending, or find ways to bring in additional income.
Working while collecting Social Security is fully permitted, and part-time work can meaningfully supplement a fixed benefit. The gig economy offers flexibility for retirees who can’t commit to a traditional schedule: rideshare driving, pet sitting, freelance consulting, and similar arrangements let people control their hours without signing on full time.
If inflation keeps moderating through August and September, the final COLA could come in at the low end of current projections, or possibly even below them. The better frame isn’t anxiety about a shrinking estimate, though. It’s using this window to run the numbers honestly, build in a margin of safety, and position yourself so that whatever the SSA announces in October, you’re already prepared.
Editor’s note: This article has been updated to reflect the latest 2027 COLA projections published after July’s CPI report, including Mary Johnson’s revised estimate of 3.4%, the Senior Citizens League’s current projection of 3.6%, and AARP’s forecast of 3.5%. The Medicare Part B section now incorporates the 2026 Medicare Trustees Report projection of a $209.50 standard monthly premium for 2027, up from $202.90 in 2026, and the official COLA announcement date of October 14, 2026 has been added.
