The 2027 Social Security COLA is not yet official. Independent estimates currently range from 3.8% to 4.7%, up from the confirmed 2.8% COLA that took effect in January 2026. The Social Security Administration will announce the final figure in mid-October 2026.
Anyone drawing Social Security or SSI benefits is likely to see a larger check in January 2027 than they received this year, based on early inflation data. How much larger remains genuinely unknown, and any figure circulating this summer, including the ones below, is a projection rather than a confirmed government number.
How the number actually gets calculated
By law, Social Security’s annual cost-of-living adjustment is tied to the Consumer Price Index for Urban Wage Earners and Clerical Workers, or CPI-W, published monthly by the Bureau of Labor Statistics.
The Social Security Administration compares the average CPI-W reading across July, August, and September of the current year against the same three months a year earlier.
Whatever percentage increase results becomes the COLA, announced in mid-October and applied to checks starting the following January. This measurement window for 2027 only opened this month, meaning July 2026 is the very first of the three months that count.
That timing matters. In 2022, an early-year forecast tracked below 1%, only for the final COLA to land at 5.9% once the actual third-quarter window closed, a reminder that spring and early-summer estimates can shift substantially before October. You can review the SSA’s own methodology directly rather than relying on any single forecaster’s model.
What the early forecasts say
The most recent CPI-W reading, for May 2026, showed a 4.4% year-over-year increase, the fastest pace since April 2023, driven largely by rising gasoline, energy, and produce prices. Based on that data, independent Social Security and Medicare analyst Mary Johnson has projected a 2027 COLA as high as 4.7%, up from her own 4.2% estimate the prior month.
The Senior Citizens League, a separate nonpartisan advocacy group, currently projects a more conservative 3.8% increase. Both groups agree on the direction: next year’s raise is very likely to exceed this year’s confirmed social security cola 2026 figure of 2.8%.
In dollar terms, a 3.8% COLA would add roughly $79 a month to the average retired-worker benefit, which currently stands near $2,026. A 4.7% COLA would deliver a noticeably larger increase, potentially one of the largest raises retirees have seen in more than two decades in percentage terms.
Readers should treat both numbers as bookends of a range rather than a confirmed outcome, since the final figure depends entirely on inflation data that has not yet been collected for July, August, or September.
What a bigger raise doesn’t fix
A higher COLA does not automatically mean more purchasing power. Rising Medicare Part B premiums are typically deducted directly from Social Security checks, and in 2026 many beneficiaries saw a meaningful share of their 2.8% raise offset by higher healthcare costs.
The Senior Citizens League’s own research estimates that the average Social Security payment has lost roughly 13.7% of its buying power since 2010, largely because CPI-W does not fully capture the healthcare and housing costs that weigh most heavily on older Americans’ budgets.
This is part of why the social security trust fund conversation and the annual COLA conversation, while related, address two different problems: one is about solvency over decades, the other is about keeping pace with prices year to year.
The 2027 COLA also has ripple effects beyond retiree checks. It typically influences VA disability compensation, SSI payments, and federal retiree pay, and it is often used as an early signal for how much retirement plan contribution limits, such as 401(k) and IRA caps, might rise the following year through a related irs rule of 55 and contribution-limit adjustment process.
If you receive Social Security or SSI, it’s reasonable to budget conservatively using the lower end of the current range, around 3.8%, rather than assuming the higher 4.7% estimate holds.
Watch for the official CPI-W releases for July, August, and September, each of which will narrow the range considerably. The confirmed figure arrives directly from SSA in mid-October, not from any private forecaster, so treat interim numbers as directional rather than final.
