Social Security recipients could see their largest cost-of-living increase since 2023, with AARP projecting a 3.6 percent adjustment for 2027. The advocacy group for people over 50 says the estimate is based on current inflation data, though the final number will not be locked in for weeks.
The Social Security Administration will announce the official 2027 COLA on October 14, once September’s inflation report is released, according to a retirement planning analysis citing the agency’s schedule. That report is critical because the COLA is calculated based on changes in consumer prices during the third quarter of the year — July, August and September — AARP said.
Estimates Vary Among Analysts
Not every group agrees on the exact figure, and the projections have shifted slightly in recent weeks. The Senior Citizens League, an advocacy group for older Americans, now projects the 2027 COLA at 3.5%, down from its prior estimate of 3.6%. Independent Social Security and Medicare policy analyst Mary Johnson estimated the COLA may be 3.5%, factoring in the latest consumer price index data. The nonpartisan Committee for a Responsible Federal Budget offered a slightly lower forecast, estimating the 2027 COLA at 3.4% based on the latest data.
Despite the small differences, every projection points in the same direction: a bigger raise than beneficiaries received this year. The COLA for 2026 was 2.8%, and a 3.6 percent adjustment would mark the biggest annual increase in Social Security payments since 2023, a financial news report said. Even the most conservative of the current estimates, at 3.4%, would still outpace last year’s bump.
What It Means for Retirees
For the roughly seventy million Americans who rely on Social Security, even fractions of a percentage point translate into real dollars. AARP calculates that a 3.6 percent COLA would increase the average retired worker’s benefit by $75 a month. That estimate is built on the average monthly Social Security benefit for a retiree in July 2026, which stood at about $2,086, according to AARP’s citation of Social Security Administration data.
Those numbers matter for household budgets already stretched by grocery, housing and health care costs. A monthly increase of $75 may not close every gap, but it represents meaningful relief for retirees living on fixed incomes, particularly those who depend on Social Security as their primary source of support. The gap between the highest estimate (3.6%) and the lowest (3.4%) may look small on paper, but multiplied across tens of millions of recipients, it adds up to billions of dollars in aggregate payments.
Beneficiaries will not have to guess indefinitely. Social Security recipients will receive their personalized notices detailing their new 2027 benefit amounts in December, a financial news report on the agency’s COLA schedule said. That gives retirees a firm date to watch for, even though the broader announcement comes two months earlier.
Retirement Savings Limits Also Set to Rise
COLA estimates are not the only retirement-related numbers in flux this fall. Contribution limits for workplace retirement plans are also projected to climb in 2027, according to Milliman, an actuarial and consulting firm.
- The 401(k), 403(b), and 457 employee elective deferral limit is projected to rise to $25,500, up from the confirmed $24,500 in 2026.
- The Super Catch-Up Contribution Limit for workers ages 60-63 is projected to increase to $11,750, up from $11,250 in 2026.
- The maximum annual addition for defined contribution plans is projected to increase from $72,000 in 2026 to $75,000 in 2027.
These projected increases would give workers, particularly those nearing retirement, more room to shelter income and build savings. The Super Catch-Up provision in particular is designed to help older workers accelerate contributions in the years just before retirement, and a higher limit could meaningfully boost the amount some are able to set aside tax-deferred.
Waiting for the Official Word
As with the Social Security COLA, none of the contribution limit figures are final. The IRS has not yet announced the official 2027 retirement-plan contribution limits and typically does so in late October or November after September inflation data is finalized, according to multiple retirement plan analyses citing IRS practice.
That means both retirees anticipating their benefit checks and workers planning next year’s retirement contributions are, for now, working from informed projections rather than confirmed figures. The consistent thread across every estimate — from AARP’s 3.6% to the Committee for a Responsible Federal Budget’s more cautious 3.4% — is that price growth over the summer months has been enough to push next year’s adjustment higher than this year’s.
Until the Social Security Administration and the IRS release their official figures, households will have to plan around a range rather than a single number. The final September inflation data, due out shortly before the October 14 announcement, will settle the question for tens of millions of Americans who depend on these adjustments to keep pace with rising costs.
