What did SSA announce for the 2027 Social Security COLA?
The SSA announced a 3.6% increase for 2027 on October 14, 2026. The adjustment is based on the change in the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) from the third quarter of 2025 through the third quarter of 2026. The agency estimates that the average Social Security retirement benefit will rise by about $75 per month; that average is not a promise of any individual's personal increase.
The annual COLA should not be confused with long-range assumptions in the SSA Trustees Report. Forecast assumptions are used to model program finances over many years; the annual adjustment is determined from observed third-quarter CPI-W data. The official annual figure for 2027 is now 3.6%.
How much could different COLA scenarios add?
Use your current gross monthly benefit to estimate the arithmetic effect of the official rate. For a $2,000 monthly benefit, 3.6% equals a gross increase of $72 per month or $864 annualized, before any rounding or deductions. This is an estimate of the COLA percentage applied to the entered amount, not a personal award calculation.
| Rate or scenario | On a $2,000 benefit | Annualized increase | Status |
|---|---|---|---|
| 3.6% | +$72/month | +$864/year | Official 2027 COLA announced by SSA on October 14, 2026 |
| 3.5% | +$70/month | +$840/year | Hypothetical comparison only |
| 3.4% | +$68/month | +$816/year | Hypothetical comparison only |
| 2.4% | +$48/month | +$576/year | Historical long-range assumption, not the annual 2027 COLA |
These are simple percentage calculations rather than official benefit determinations. Your actual payment may differ because of benefit rules, rounding, Medicare premiums, tax withholding or other deductions. The Social Security Administration does not use a personal benefit amount to determine the COLA rate.

How the SSA calculates COLA
The annual adjustment is based on the change in the average CPI-W for July, August and September compared with the average for the third quarter of the last year in which a COLA became effective. The percentage change is rounded to the nearest tenth of a percentage point. This is why the September inflation release is a key date: the full third-quarter data set is needed to determine the adjustment.
The Bureau of Labor Statistics released September 2026 CPI data on October 14. The CPI release supplies data used in inflation analysis; it is not itself the SSA's published COLA determination. SSA has now published the official 2027 rate: 3.6%. Its COLA page records the 3.6% result and the underlying CPI-W calculation.
When will the 2027 increase appear in payments?
The 3.6% COLA applies to Social Security benefits payable in January 2027. Increased Supplemental Security Income (SSI) payments begin on December 31, 2026. People with a personal my Social Security account can check their individual COLA notice online in late November if they meet SSA's paperless-notice conditions; the published rate alone does not reveal a person's net deposited amount.
Why a personal payment may differ from the estimate
The calculator multiplies a user-entered gross monthly amount by the published COLA percentage. It does not reconstruct the SSA's full benefit formula or calculate net payments after Medicare premiums, tax withholding, overpayment recovery or other deductions. Use your official notice or personal my Social Security account for your actual benefit amount.
