The Social Security cost-of-living adjustment (COLA) for 2026 is 2.8%, according to the Social Security Administration. That means the average retired worker’s monthly benefit rises by roughly $56, from about $1,976 to around $2,032, starting with the January 2026 payment. Exact amounts vary by individual work history, so your real number will show up in your online Social Security account before the check arrives.
What the COLA Actually Is
The COLA isn’t a raise Congress votes on. It’s a formula built into the Social Security Act, designed to keep benefits from losing purchasing power as prices rise. Each year, SSA compares average prices from the third quarter (July, August, September) of the current year to the same three months of the prior year, using a specific inflation gauge called the CPI-W — the Consumer Price Index for Urban Wage Earners and Clerical Workers. Whatever percentage prices rose, benefits rise by that same percentage the following January.
For 2026, that comparison produced a 2.8% increase, which SSA announced in October 2025, per SSA.gov. This is slightly higher than the 2.5% COLA applied in 2025, reflecting somewhat stickier inflation in categories like housing, food, and medical care over the measurement period.
Why the Amount Differs From Person to Person
The 2.8% applies to your gross benefit amount, not to a flat dollar figure everyone gets. That’s why headlines quote an “average” increase — the actual dollar change depends on what you were already receiving.
- Someone getting $1,200/month sees about a $34 increase.
- Someone getting $2,000/month sees about a $56 increase.
- Someone getting $3,000/month sees about a $84 increase.
If part of your benefit is withheld for Medicare premiums or tax withholding, your net deposit changes by a different amount than your gross benefit. The COLA is applied before those deductions. (Note: the Windfall Elimination Provision, which used to reduce benefits for some public-sector retirees, was repealed by the Social Security Fairness Act signed in January 2025 — if that provision affected you in the past, your 2026 benefit is calculated without it.)
How COLA Percentages Have Trended
| Year | COLA | Average Retired Worker Benefit (after increase) |
|---|---|---|
| 2022 | 5.9% | ~$1,657/month |
| 2023 | 8.7% | ~$1,827/month |
| 2024 | 3.2% | ~$1,907/month |
| 2025 | 2.5% | ~$1,976/month |
| 2026 | 2.8% | ~$2,032/month |
Figures are SSA-reported averages and will differ from any individual’s actual payment. Confirm current numbers at SSA.gov, since averages are periodically restated.
The 8.7% jump for 2023 was the largest in over 40 years, driven by the inflation spike of 2021–2022. The 2026 figure of 2.8% is closer to the program’s longer-run historical average, which has hovered in the 2%–3% range in most years since the early 2000s.
When the Increase Shows Up
Social Security benefits are paid a month behind, so the January 2026 payment (covering December 2025) is the first one to reflect the new 2.8% rate. Payment timing follows the usual schedule based on your birth date:
- Birthdays on the 1st–10th: paid the second Wednesday of the month
- Birthdays on the 11th–20th: paid the third Wednesday of the month
- Birthdays on the 21st–31st: paid the fourth Wednesday of the month
If you receive Supplemental Security Income (SSI), the COLA typically shows up a bit earlier — in the December 31, 2025 payment — because SSI follows a different payment calendar designed to avoid January 1 falling on a weekend or holiday. Check SSA.gov for the exact SSI payment date each year, since it can shift.
Where COLA Notices Come From
Starting in early December, SSA mails or posts COLA notices explaining your new benefit amount. If you have a “my Social Security” account at ssa.gov/myaccount, you’ll typically see the notice online before a paper copy arrives, and you can opt out of paper mail entirely. This is the most reliable way to confirm your specific 2026 amount rather than relying on the national average.
The Medicare Part B Offset
For most retirees, the COLA increase doesn’t translate dollar-for-dollar into a bigger deposit, because Medicare Part B premiums are usually deducted directly from Social Security checks. Part B premiums are set annually by the Centers for Medicare & Medicaid Services (CMS) and typically increase each January as well, sometimes offsetting part of the COLA.
For 2026, CMS set the standard Part B premium at $202.90 per month, up $17.90 from $185.00 in 2025, with the annual Part B deductible rising to $283. For someone receiving the average retired-worker benefit, that premium increase absorbs roughly a third of the $56 COLA gain.
There’s a consumer protection here called the “hold harmless” provision: for most beneficiaries, your Social Security check cannot decrease year-over-year because of a Medicare premium increase alone. With a 2.8% COLA, this rarely comes into play in 2026, since the increase is generally large enough to absorb the premium adjustment.
SSI Recipients and the 2026 COLA
Supplemental Security Income follows the same COLA percentage as Social Security retirement and disability benefits, since both are tied to the same CPI-W formula under federal law. For 2026, the maximum federal SSI payment increases by 2.8% as well. As of 2025, the maximum federal SSI payment was $967/month for an individual and $1,450/month for a couple; both figures rise proportionally for 2026. Many states add a supplemental payment on top of the federal amount, and those state add-ons follow separate rules — contact your state’s SSI supplement office or check SSA.gov’s state-by-state page to confirm your total.
Does the COLA Affect the Taxable Maximum or Earnings Limits?
Separately from the COLA, SSA also adjusts a few other figures each January based on national wage growth rather than the CPI-W:
- The maximum amount of earnings subject to Social Security payroll tax (the “taxable maximum”) typically rises each year.
- The earnings limit for people who claim benefits before full retirement age and continue working also adjusts annually.
These numbers move independently of the COLA percentage, so don’t assume a 2.8% COLA year means a 2.8% change to the earnings limit or taxable maximum. SSA.gov publishes the exact 2026 figures for both each fall alongside the COLA announcement.
How to Confirm Your Exact 2026 Benefit
- Log in to your account at ssa.gov/myaccount.
- Look for your COLA notice, usually posted in early December 2025.
- Compare your new gross benefit to your 2025 amount to see the dollar change.
- Check whether your Medicare Part B premium changed, since that affects your net deposit.
- If you don’t have an online account, SSA will mail a paper notice; call 1-800-772-1213 if you haven’t received one by early January.
Bottom Line
The 2.8% COLA for 2026 keeps benefits moving with inflation, but the real number that matters is the one on your personal notice, not the national average. Between the COLA itself and any change to your Medicare premium, your actual deposit could shift up by more or less than the headline percentage suggests. The safest move is to check your my Social Security account directly rather than estimating from averages.
FAQ
How is the 2026 Social Security COLA percentage decided?
It’s based on the change in the CPI-W index between the third quarter of 2024 and the third quarter of 2025, as calculated by the Bureau of Labor Statistics and applied by SSA under a formula set in federal law. SSA doesn’t set the number by policy choice; it’s a mechanical calculation.
Will my Social Security check actually go up by 2.8%?
Your gross benefit increases by 2.8%. Your net deposit may increase by a different amount if your Medicare Part B premium, tax withholding, or other deductions also change for 2026. Compare your official COLA notice to your prior year’s amount for the true difference.
When will I know my exact new benefit amount for 2026?
SSA typically posts COLA notices to online “my Social Security” accounts in early December, with mailed notices following shortly after. The updated amount takes effect with the January 2026 payment (or the December 2025 payment for SSI recipients).
