What Changed for 2026
The Social Security Administration announced a 2.8% cost-of-living adjustment (COLA) for 2026 — slightly below the roughly 3% inflation rate it's meant to track, and up from the 2.5% adjustment applied in 2025. For the average retired worker, that works out to about $56 more per month.
Nearly 71 million Social Security beneficiaries and about 7.5 million SSI recipients — roughly 75 million people combined — see this increase reflected in their payments.
📅
When it took effect: The increase applies to Social Security retirement, survivor, and disability benefits starting with the
January 2026 payment. SSI recipients saw it a bit earlier, with the
December 31, 2025 payment (which is SSI's January benefit, paid early — see our
SSI double payment guide for why).
How SSA Actually Calculates the COLA
The COLA isn't a political decision made fresh each year — it's a fixed formula. SSA compares the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) from the third quarter (July–September) of the current year to the same quarter of the prior year. The percentage change becomes next year's COLA, announced every October.
- If CPI-W rises, benefits go up by that percentage the following January.
- If CPI-W doesn't rise, there's no COLA that year — benefits simply stay flat, which has happened in years like 2010, 2011, and 2016.
- The formula is automatic and doesn't require an act of Congress each year — it's been law since 1975.
What Else Moved Alongside the COLA
A few related numbers update every year in step with the COLA announcement:
- Maximum taxable earnings: The cap on wages subject to Social Security payroll tax rose to $184,500 for 2026, up from $176,100 in 2025. This affects what higher earners pay into the system, not what current retirees receive.
- Full retirement age (FRA) earnings limits: If you're working while collecting benefits before reaching FRA, the amount you can earn before benefits are temporarily withheld also adjusts most years.
⚠️ A COLA increase isn't pure "extra" income in practice for everyone — Medicare Part B premiums, which are often deducted directly from Social Security checks, also tend to rise each year and can offset part of the increase. Check your actual benefit statement rather than assuming the full 2.8% lands in your pocket.

2.8%, raising the average retirement benefit by about $56 a month.
When does the 2026 COLA take effect?
January 2026 for Social Security retirement, survivor, and disability benefits. SSI recipients saw it with the December 31, 2025 payment.
How is the COLA percentage calculated?
