The 2026 Social Security COLA: 2.8% on paper, less in your bank account

Your Social Security check went up 2.8% in January. For the average retired worker, that’s about $56 more a month. But before you spend it, look at the Medicare Part B line on your benefit statement: the standard premium jumped from $185 to $202.90, an increase of $17.90. That single deduction quietly absorbs roughly a third of the typical raise, and for some retirees it eats nearly all of it.

What is the 2026 COLA, and how was it set?

On October 24, 2025, the Social Security Administration announced a 2.8% cost-of-living adjustment for 2026. The figure is calculated automatically from the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), comparing the third quarter of 2025 with the third quarter of 2024. There’s no vote, no political haggling — the formula has been in statute since 1972.

The 2.8% raise is bigger than 2025’s 2.5% but smaller than the 8.7% spike in 2023, which was the largest in four decades. About 71 million Social Security beneficiaries see the increase starting with their January 2026 payment, and roughly 7.5 million Supplemental Security Income (SSI) recipients saw it slightly earlier, on December 31, 2025, according to the SSA’s 2026 COLA fact sheet.

If you want to see your exact new amount, log in to your my Social Security account at ssa.gov/myaccount. SSA mailed COLA notices in December 2025, but the online statement is the cleanest way to confirm the deposit and check whether your Medicare premium changed at the same time.

How much extra money will actually hit your account?

Here is where the headlines and the deposit slip part ways. SSA says the average retired worker’s benefit rises by about $56 a month in 2026, lifting the typical check from roughly $2,008 to about $2,064. A retired couple where both partners receive benefits sees, on average, around $90 more a month combined.

Now subtract Medicare. The Centers for Medicare & Medicaid Services set the standard Part B premium at $202.90 for 2026, up $17.90 from $185 in 2025 — an increase of just under 10%. Most retirees have Part B deducted directly from their Social Security payment, so the premium hike comes off the top before the money lands. For the average retired worker, that leaves roughly $38 a month in net new income, not $56.

The Center for Retirement Research at Boston College ran the numbers and found Part B premiums will absorb more than a quarter of the average retiree’s 2026 COLA, pushing premiums to roughly 9.4% of the average benefit — an all-time high. It’s the third year in a row that the Part B premium has climbed faster than the COLA itself.

Who is most exposed when the premium rises faster than the COLA?

Federal law includes a “hold harmless” provision that’s supposed to prevent your net Social Security check from shrinking year over year because of a Part B premium increase. The catch is that it only kicks in when the dollar value of your COLA is smaller than the dollar value of the premium hike. For 2026, that math means hold harmless mainly protects retirees whose monthly benefit is roughly $639 or less, according to AARP’s analysis of the 2026 increase.

Several groups don’t get the hold-harmless cushion at all. New Medicare enrollees in 2026, retirees who pay Part B by quarterly bill rather than benefit deduction, anyone subject to Income-Related Monthly Adjustment Amount (IRMAA) surcharges, and people enrolled through Medicare Savings Programs all pay the full new premium without protection. If you fall into any of those buckets and your benefit is small, a chunk of the COLA can vanish before you notice.

Higher earners feel the squeeze in a different way. The 2026 IRMAA schedule starts at modified adjusted gross income above $109,000 for an individual filer, where the monthly Part B premium climbs to $284.10. It tops out at $689.90 a month for individuals reporting more than $500,000 in income two years earlier. IRMAA is based on your 2024 tax return, so a one-time event in that year — a Roth conversion, a home sale, a large capital gain — can lift your premium right when the COLA arrives.

Other 2026 numbers that move with the COLA

The 2.8% adjustment ripples through several other Social Security thresholds. Workers and the self-employed should note these in particular:

• The Social Security taxable maximum rises to $184,500, up from $176,100 in 2025. Earnings above that ceiling aren’t subject to the 6.2% Social Security payroll tax.
• The earnings limit for beneficiaries under full retirement age climbs to $24,480 a year. Above that, SSA withholds $1 in benefits for every $2 you earn.
• The earnings limit in the year you reach full retirement age rises to $65,160, with $1 withheld for every $3 above the limit until the month you hit FRA.
• The maximum benefit for a worker retiring at full retirement age in 2026 is roughly $4,152 a month, while a worker who waited until age 70 can receive up to about $5,181.

Medicare’s other 2026 figures are worth tracking too. The Part B annual deductible rises to $283 (up $26), and the Part A inpatient hospital deductible rises to $1,736 per benefit period (up $60). Daily Part A coinsurance is $434 for hospital days 61-90 and $217 for skilled nursing facility days 21-100. If you’re navigating the new Part D rules at the same time, see our explainer on the $2,000 Medicare Part D out-of-pocket cap — that cap is the biggest piece of Medicare drug-cost relief retirees will see in 2026.

What to do with the raise — and the bills that come with it

First, verify the numbers on your own statement. The COLA notice mailed by SSA in December and the online benefit verification letter both show your new gross benefit, your Part B deduction, any IRMAA surcharge, and the net deposit. If the IRMAA surcharge looks wrong because your income has dropped — say, after retirement — you can ask SSA to reconsider using Form SSA-44 (Medicare Income-Related Monthly Adjustment Amount – Life-Changing Event). Common qualifying events include retirement, the death of a spouse, divorce, or the loss of pension income.

Second, recheck your federal tax withholding from Social Security. You can have 7%, 10%, 12%, or 22% withheld using Form W-4V. With a higher gross benefit and possibly higher RMDs from retirement accounts, more of your benefit may be taxable in 2026 than in 2025. The IRS has a free Tax Withholding Estimator that handles Social Security as one of its inputs. Any decision about Roth conversions, withdrawals, or charitable giving that could affect your 2026 income deserves a conversation with a tax professional, especially if you’re near an IRMAA threshold for 2028 (since IRMAA looks back two years).

Third, run a quick check on your supplemental coverage. Medigap premiums and Medicare Advantage out-of-pocket maximums also moved in January, and the COLA may not keep pace if you’re in a plan that re-rated aggressively. If you’re shopping coverage, the official Plan Finder at medicare.gov is the only tool that shows your specific drug list and pharmacy pricing. For the new Part D structure, our walkthrough of the 2026 Part D out-of-pocket cap lays out how the $2,000 ceiling and the new monthly payment plan interact with your COLA dollars.

What to remember

The 2.8% COLA is real, and for the average retired worker it adds about $56 a month to the gross benefit, $2,064 instead of $2,008. The Part B premium hike of $17.90 is also real, and it absorbs roughly a third of that raise before the deposit hits. If your benefit is small, your premium is subject to IRMAA, or you’re new to Medicare in 2026, the hold-harmless rule won’t save you. Confirm your numbers in my Social Security, watch your withholding, and treat the COLA as smaller than the headline implies.
