Interestingly, the group’s prediction has actually moved around during the year.
In July, it projected a 3.8% adjustment. By August, that estimate had fallen slightly to 3.6%.
That movement shows why retirees should treat every prediction cautiously until the final inflation figures arrive.
When Will the Official 2027 COLA Be Announced?
Beneficiaries will not have to wait much longer.
The Social Security Administration is expected to announce the official 2027 COLA on October 14, 2026, after the government receives the inflation data needed to complete the calculation.
The new Social Security benefit amount would then generally begin with payments received in January 2027.
SSI recipients follow a slightly different payment calendar. For example, when the 2026 COLA took effect, increased SSI payments began with the December 31, 2025 payment because January 1 was a federal holiday.
Who Could Receive the Increase?
The adjustment doesn’t apply only to traditional retirees.
Social Security provides benefits to several groups, including retired workers, people receiving qualifying disability benefits and certain survivors of deceased workers.
The COLA also affects Supplemental Security Income, or SSI.
SSI provides monthly payments to qualifying people with limited income and resources, including adults age 65 or older and people who meet disability or blindness requirements.
For 2026, the maximum federal SSI amount is $994 per month for an eligible individual and $1,491 for an eligible couple, before considering income, living arrangements or additional state payments.
Those figures could also increase when the 2027 COLA takes effect.
A Bigger COLA Isn’t Always Completely Good News
Seeing a larger COLA percentage may sound like welcome news.
But there is another side to the story.
COLA increases generally happen because prices have gone up.
A retiree receiving an additional $60 or $70 each month may already be paying significantly more for groceries, housing, electricity, insurance or medical expenses.
That means a larger Social Security check does not automatically translate into substantially more disposable income.
The purpose of COLA isn’t necessarily to make beneficiaries richer. It is intended to help their benefits maintain purchasing power as the cost of living changes.
Don’t Count on the 3.6% Number Yet
There are still several weeks of inflation data to come before the government can calculate the official increase.
If inflation moves higher, the final COLA could rise.
If inflation cools, the adjustment could come in below current estimates.
For now, the most important dates for Social Security recipients to remember are October 14, 2026, when the official adjustment is expected to be announced, and January 2027, when the new Social Security benefit amounts are expected to begin.
Until then, the projected 3.6% increase — or roughly $69.75 more per month for an average beneficiary under The Senior Citizens League’s example — should be viewed as an estimate, not a guaranteed payment increase.
For millions of retirees living on tight monthly budgets, however, even the possibility of a larger adjustment will make the upcoming October announcement one worth watching closely.
