Social Security recipients are currently on track for a bigger cost-of-living adjustment in 2027 than they received this year, although the final number remains uncertain.
Independent Social Security analyst Mary Johnson estimates a 3.4% COLA, while The Senior Citizens League projects 3.6%. Both forecasts are above the 2.8% increase applied in 2026, which raised benefits for roughly 75 million Social Security and Supplemental Security Income recipients. The official 2027 adjustment will not be known until October.
July provided the first inflation reading that directly enters the calculation. The BLS report showed CPI-W rising 3.4% from a year earlier, while the broader CPI increased just 0.1% during the month.
A Higher COLA Does Not Necessarily Mean More Buying Power
A larger adjustment may sound positive, but Social Security COLAs are designed primarily to preserve purchasing power rather than make retirees wealthier.
The COLA formula uses the Consumer Price Index for Urban Wage Earners and Clerical Workers, comparing the average CPI-W reading for July, August and September with the corresponding quarter a year earlier.
That means a higher adjustment usually reflects faster price increases.
For example, a 3.6% COLA would add roughly $75 per month to a $2,084 monthly benefit, lifting it to about $2,159. But retirees may simultaneously face higher costs for housing, food, energy, health care and insurance.
The latest Coinpaper coverage of inflation illustrates why the distinction matters: softer headline inflation can help financial markets while household expenses can remain elevated in individual categories.
Two Inflation Reports Will Decide the Final Number
Neither current estimate is guaranteed. August and September CPI-W readings still have to be included before Social Security can calculate the official adjustment.
If inflation continues cooling, the COLA could finish below current projections. Another acceleration in prices could push it higher.
That uncertainty is why retirees should avoid building a budget around a preliminary figure. Medicare premiums can also reduce the increase that ultimately reaches a beneficiary's bank account.
For households that rely on investments alongside Social Security, income-producing assets such as individual bonds or bond ETFs can play a separate role in retirement planning, though they carry their own interest-rate and market risks.
Coinpaper's earlier COLA outlook shows how quickly forecasts have changed as inflation data arrived: estimates that reached 3.8% earlier this summer have already moved lower.
For now, 3.4% to 3.6% is the most useful working range for the 2027 Social Security COLA. The final adjustment will depend on the next two CPI-W reports, with the official figure expected after September inflation data are released in October.
