Social Security beneficiaries are getting a 2.8% cost-of-living adjustment (COLA) in 2026, but a nearly 10% jump in Medicare Part B premiums will trim how much of that raise actually shows up in monthly checks. Understanding the interaction between COLA and Medicare costs is crucial to knowing your true “take-home” increase for the year.
2026 COLA: The Headline Raise
For 2026, Social Security and SSI benefits rise by 2.8%, based on inflation measured by the CPI-W from the third quarter of 2024 to the third quarter of 2025. The average retired worker benefit is projected to go from about 2,015 per month in 2025 to roughly 2,071 in January 2026, a gain of around 56.
Other groups see similar percentage increases: average benefits for all disabled workers rise from 1,586 to 1,630, and the maximum benefit at full retirement age climbs from 4,018 to 4,152. On paper, this COLA looks like meaningful progress against inflation, but fixed healthcare costs tell a different story.
Medicare Part B Premiums Are Jumping
The standard Medicare Part B premium is set to increase from 185.00 in 2025 to 202.90 in 2026, a rise of 17.90 per month—just under 10%. Because most retirees have their Part B premium deducted directly from their Social Security check, this higher charge slices into the COLA before it ever reaches a checking account.
Analysts note that Part B premiums are growing several times faster than the COLA, so health-care costs will eat up a larger share of retirement income in 2026 than they did the year before. For many retirees, nearly one-third of the COLA increase will be absorbed by the higher Part B bill alone.
What Your “Real” Increase Looks Like
The table below gives a simplified picture of how the 2026 COLA and the Part B hike interact for a typical retiree paying the standard premium. It uses the SSA’s estimated average retired worker benefit and assumes premiums are deducted from Social Security.

In this example, the headline COLA is 2.8%, but the net increase after Part B is closer to 2.1% because 17.90 of the raise is immediately diverted to medical premiums. Lower-benefit recipients feel an even bigger bite, since the same 17.90 premium uses up a larger share of a smaller check.
Hold Harmless: A Limited Safety Net
Social Security’s “hold harmless” rule prevents a beneficiary’s net check from going down just because the Part B premium rises more than that person’s dollar COLA. To qualify, your Part B premium must be deducted from your Social Security benefit, and you cannot be subject to income-related premium surcharges.
For those protected by hold harmless, the COLA will be applied first and the Part B premium increase is effectively capped so that the net deposit is at least flat or slightly higher. However, beneficiaries with higher incomes who pay income-related monthly adjustment amounts, as well as people who pay Part B directly instead of through Social Security, can still see their out-of-pocket costs jump more than their COLA.
Who Feels The Squeeze The Most?
Retirees with modest Social Security checks are often hit hardest because fixed health-care costs consume a larger percentage of their income. Someone receiving 1,000 a month may see a COLA of about 28, but still faces the same 17.90 premium hike, leaving only a small net improvement in spending power.
People with chronic conditions or frequent doctor visits also feel the effect of the higher Part B deductible, which rises to 283 in 2026, up from 257 in 2025. When premiums, deductibles, and copays rise together, even a historically “good” COLA can leave retirees feeling like they are running in place.
Strategies To Protect Your Net Benefit
To see your true 2026 increase, review your Social Security COLA notice and your Medicare plan materials side by side, focusing on the difference between this year’s and next year’s net deposit. If your budget looks tight, options include shopping for a more cost-effective Medicare Advantage or Medigap plan and reviewing prescription coverage to reduce out-of-pocket costs.
Building a small emergency cushion and tracking recurring bills can also help manage months when medical costs spike. For those with very limited income and assets, it may be worth exploring programs like Medicaid, Medicare Savings Programs, or Extra Help with drug costs, which can offset premiums and copays.
Q1: When will I see the 2026 COLA in my payment?
Most Social Security beneficiaries see the 2.8% COLA reflected in checks dated January 2026, which are paid on the usual January schedule based on birth date. SSI recipients receive the higher amount with the January 2026 benefit, which may be deposited at the end of December 2025 if the first falls on a holiday.
Q2: What is the new standard Medicare Part B premium for 2026?
The standard Part B premium is 202.90 per month in 2026, up 17.90 from 185.00 in 2025, an increase of just under 10%. Higher-income enrollees pay more based on income-related surcharges, which can push their monthly premium well above the standard rate.
Q3: How can I estimate my own net COLA after premiums?
Start with your current gross Social Security benefit, multiply it by 1.028 to get your 2026 gross, then subtract the new Part B premium you will owe. Comparing that net number with your current net (after today’s premium) reveals how much real extra money you will actually have each month.
