Social Security’s 2027 COLA Is Here: What Retirees, SSDI and SSI Recipients Will Get Each Month

This morning, more than 70 million Americans find out how much bigger their Social Security checks will be in 2027. The Social Security Administration announces its annual cost-of-living adjustment today, right after the Bureau of Labor Statistics releases September inflation data at 8:30 a.m. Eastern — and every major forecast points to the largest raise in three years.

The most-cited projection is 3.5%, according to the Senior Citizens League, with AARP forecasting 3.6% and the Committee for a Responsible Federal Budget at 3.4%. If the final number lands in that range, it would top the 2.8% increase recipients got in 2026 and be the biggest bump since 2023’s 8.7%. The figure comes from a fixed statutory formula — the average of July, August, and September CPI-W inflation data compared to the same three months last year — and the agency has no discretion over the result.

Here is what a projected 3.5% would mean in dollars, based on current average benefits: retired workers would gain roughly $73 a month (on an average benefit of about $2,071), disabled workers on SSDI about $59, spouses about $36, and survivors about $59. The raise would first show up in January 2027 payments, with SSI recipients seeing it on December 31, 2026. It is automatic — no application, no action needed.

The Biggest Raise in Three Years

For retirees watching every dollar, the headline is welcome. Social Security Commissioner Frank Bisignano appeared on CNBC this week and called the forthcoming adjustment “a good day” for seniors. After years of 2.5% and 2.8% adjustments, a mid-3% increase would be the strongest since the post-pandemic inflation spike — real money landing in January for people who plan their budgets around these checks.

The mechanics are straightforward. Because Social Security pays a month in arrears, the December 2026 benefit — the first one carrying the new rate — arrives in January 2027. SSI works on a different clock: January’s payment comes December 31, since New Year’s Day is a holiday. Either way, beneficiaries do not need to do anything; the increase applies automatically.

But Will It Cover Real Costs?

Here is where the celebration meets the math. The Senior Citizens League’s own analysis found that Social Security benefits have lost 13.7% of their buying power over the past decade — a dollar of benefits in 2016 is worth about 86 cents today. To fully restore that lost ground, the average beneficiary would need nearly $296 more a month, not $73.

Then there is Medicare. The standard Part B premium is forecast to rise about $6.60 a month in 2027, which comes straight out of most retirees’ checks before they see a cent of the raise. Independent analyst Mary Johnson put it bluntly to CNN: recent inflation “has not gone away” and “heated right back up,” with gas, beef, and healthcare costs soaring. The league’s executive director noted that seniors cannot substitute their way out of these costs — “you can’t substitute your medications for something else.”

That gap is why some advocates keep pushing to change the formula itself, swapping CPI-W for an index based on seniors’ actual spending patterns. Those proposals have not moved far in Congress.

So is 3.5% a victory or a bandage? For a retiree choosing between prescriptions and groceries, $73 a month is not nothing — but it is not restoration either. The official number posts this morning. The debate over whether it is enough will run a lot longer than the announcement.
