Every year, Social Security benefits receive a cost-of-living adjustment (COLA) designed to help retirees keep pace with inflation. But for Medicare beneficiaries, the COLA does not tell the whole story. When Medicare premiums rise faster than your Social Security increase — as they did for 2026 — the net result is a smaller take-home check than you might expect. This guide breaks down the numbers, explains the protections in place, and shows you practical ways to offset rising costs.

What Is the 2026 Social Security COLA?

The Social Security Administration announced a 2.8% cost-of-living adjustment for 2026, effective with January 2026 benefit payments. This was determined by the percentage increase in the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) from the third quarter of 2024 to the third quarter of 2025.

A 2.8% COLA is relatively modest by recent standards. For context, the 2023 COLA was 8.7% (the largest in four decades), the 2024 COLA was 3.2%, and the 2025 COLA was 2.5%. While 2.8% does represent positive growth, it translates to a relatively small dollar amount for most retirees.

What Does 2.8% Mean in Dollars?

The average retired worker received approximately $1,790 per month in Social Security benefits in 2025. A 2.8% increase adds about $50 per month, bringing the average benefit to roughly $1,840 per month before any deductions.

Monthly Benefit (2025) 2.8% COLA Increase New Monthly Benefit (2026)
$1,200 +$33.60 $1,233.60
$1,500 +$42.00 $1,542.00
$1,790 (average) +$50.12 $1,840.12
$2,200 +$61.60 $2,261.60
$2,800 +$78.40 $2,878.40
$3,822 (max at 66) +$107.02 $3,929.02

These figures are gross amounts — before Medicare premiums and any federal or state income tax withholding are deducted from your check.

The Part B Premium Increase for 2026

While the COLA provided a 2.8% raise, the standard Medicare Part B premium increased from $185.00 per month in 2025 to $202.90 per month in 2026 — an increase of $17.90 per month, or 9.7%.

CMS attributed the increase to several factors:

  • Rising health care utilization as the post-pandemic surge in medical visits continues
  • Increased Part B drug spending, particularly for new Alzheimer’s treatments and cancer therapies administered in outpatient settings
  • Higher-than-expected program costs that exceeded previous actuarial projections
  • Building reserves to maintain the Part B trust fund’s financial stability

The Part B deductible also rose from $257 in 2025 to $283 in 2026, adding another $26 to your annual out-of-pocket costs.

The Math Problem A 2.8% raise on a $1,790 benefit adds $50.12 per month. But the Part B premium increase alone takes $17.90 of that. If you also pay a Part D premium that increased, your net raise shrinks even further. For many retirees, the real purchasing-power increase from the 2026 COLA is closer to $25–$30 per month.

Net Impact on Your Monthly Check

Let us walk through a realistic example to illustrate how the 2026 COLA and Part B premium increase interact:

Line Item 2025 2026 Change
Gross Social Security Benefit $1,790.00 $1,840.12 +$50.12
Part B Premium -$185.00 -$202.90 -$17.90
Part D Premium (avg.) -$42.00 -$46.00 -$4.00
Net Monthly Check $1,563.00 $1,591.22 +$28.22

In this example, the retiree’s gross raise of $50.12 is reduced to a net increase of just $28.22 per month — about $339 for the year. That is the real purchasing power gained from the 2026 COLA after Medicare premiums are factored in. And this example does not account for increased costs for groceries, housing, utilities, and other everyday expenses that the COLA is meant to offset.

The Hold Harmless Provision

There is one important protection built into the system. The Social Security Act’s hold harmless provision prevents your net Social Security check from decreasing due to a Part B premium increase. Here is how it works:

  • If the dollar amount of the Part B premium increase exceeds your COLA dollar increase, your Part B premium is capped so that your Social Security payment stays the same as the previous year (it does not go down).
  • The protection applies to most beneficiaries whose Part B premiums are deducted from Social Security.
  • It does not apply if you are subject to IRMAA surcharges, if you are newly enrolled in Part B, or if you do not receive Social Security benefits.

For 2026, the hold harmless provision is unlikely to be triggered for most beneficiaries because the COLA increase ($50.12 on average) exceeds the Part B premium increase ($17.90). However, beneficiaries with very low Social Security benefits — say, $500 per month — would see a COLA of only $14.00, which is less than the $17.90 Part B increase. In that case, hold harmless would cap the Part B premium increase at $14.00 for that individual.

Who Is NOT Protected? The hold harmless provision does not apply to: (1) people who pay IRMAA surcharges, (2) people newly enrolling in Medicare Part B, (3) people who do not have Part B premiums deducted from Social Security, and (4) people enrolled in Medicaid (state pays Part B). If you fall into one of these groups, you pay the full Part B increase regardless of the COLA.

Historical COLA vs. Part B Premium Changes

The tension between COLA increases and Part B premium increases is not new. In many recent years, Part B premiums have risen faster than the COLA, steadily eroding the real value of Social Security for Medicare beneficiaries.

Year COLA % Part B Premium Part B Change Net Effect
2020 1.6% $144.60 +$9.10 COLA partially offset
2021 1.3% $148.50 +$3.90 Small net gain
2022 5.9% $170.10 +$21.60 COLA mostly absorbed
2023 8.7% $164.90 -$5.20 Rare net boost
2024 3.2% $174.70 +$9.80 COLA partially offset
2025 2.5% $185.00 +$10.30 COLA partially offset
2026 2.8% $202.90 +$17.90 COLA significantly offset

The 2023 year was an unusual bright spot: the large 8.7% COLA combined with a Part B premium that actually decreased (due to the resolution of uncertainty around Aduhelm pricing) gave retirees a notable net increase. But the general trend is clear — Part B premiums have been growing faster than COLA adjustments over the past decade, gradually reducing the real purchasing power of Social Security benefits.

Strategies to Offset Rising Medicare Costs

While you cannot control the COLA or Part B premium increases, there are concrete steps you can take to reduce the impact on your budget:

1. Review Your Coverage Every Year

During the Annual Enrollment Period (October 15 – December 7), compare your current plan against other available options. Plans change their premiums, formularies, and provider networks every year. Even if your plan was the right choice last year, it may not be this year. Switching plans during AEP may help you find coverage that better fits your needs and budget.

2. Check Eligibility for Assistance Programs

Several programs exist to help lower-income Medicare beneficiaries afford their premiums and cost-sharing:

  • Medicare Savings Programs (MSPs): State-administered programs that pay some or all of your Part B premium. Income limits vary by state but are generally up to 135% of the federal poverty level for the QMB program and up to 200% for certain other MSPs.
  • Extra Help (Low-Income Subsidy): Helps pay for Part D premiums, deductibles, and copays. Individuals with income below roughly $22,590 and limited assets may qualify.
  • North Carolina SHIIP: North Carolina’s free counseling program that helps seniors navigate Medicare options and assistance programs.

3. Manage Your Income to Avoid IRMAA

If your income is near an IRMAA threshold, strategic income management can save you thousands. Keeping your MAGI below $109,000 (individual) or $218,000 (married filing jointly) avoids the first IRMAA tier entirely. See our detailed guide: What Is IRMAA and How to Avoid Paying More for Medicare.

4. Maximize Preventive Care Benefits

Medicare covers many preventive services — including annual wellness visits, screenings, and vaccines — at zero cost-sharing. Using these free benefits proactively can help catch health issues early, potentially avoiding expensive treatments down the road that would increase your out-of-pocket spending.

5. Consider a Medicare Advantage Plan

Many Medicare Advantage plans offer $0 monthly premiums (beyond your Part B premium), include prescription drug coverage, and provide dental, vision, and hearing benefits that Original Medicare does not cover. The trade-off is using a provider network and accepting plan-specific rules about referrals and prior authorizations.

Medigap vs. Medicare Advantage: Cost Considerations

When evaluating how to manage rising Medicare costs, the choice between Original Medicare with a Medigap plan and Medicare Advantage plays a major role in your annual spending.

Cost Factor Original Medicare + Medigap Medicare Advantage
Part B Premium $202.90/mo (required) $202.90/mo (required)
Additional Plan Premium $90–$300+/mo (Medigap) $0–$50/mo (many are $0)
Part D Premium $15–$80/mo (standalone) Often included ($0 extra)
Annual Deductibles $283 (Part B); covered by Medigap G Varies by plan ($0–$500+)
Out-of-Pocket Maximum None (Medigap covers gaps) $3,000–$8,300 (in-network)
Dental/Vision/Hearing Not included (buy separately) Often included
Provider Choice Any Medicare-accepting provider Network-based (HMO/PPO)

For healthy retirees on a tight budget, a $0-premium Medicare Advantage plan can significantly reduce monthly expenses compared to Medigap. However, if you have significant health care needs or value the freedom to see any doctor without network restrictions, Original Medicare with a Medigap plan may provide better value over time — despite the higher monthly premium.

North Carolina Tip North Carolina uses “attained-age” rating for most Medigap plans, meaning your premiums increase as you get older. Factor this into your long-term cost projections. A Medigap plan that costs $120/month at age 65 may cost $200+/month by age 75. Medicare Advantage premiums, by contrast, do not increase based on your age (though they can change annually based on the plan’s overall pricing).

Frequently Asked Questions

The 2026 Social Security cost-of-living adjustment (COLA) is 2.8%. For the average retired worker receiving about $1,790 per month in 2025, this translates to an increase of roughly $50 per month, bringing the average benefit to approximately $1,840 per month before Medicare premium deductions.
The hold harmless provision prevents your Social Security check from decreasing due to a Medicare Part B premium increase. If the dollar amount of the Part B increase exceeds your COLA increase, your Part B premium is capped so your Social Security payment does not go down. This protection applies to most beneficiaries who have Part B premiums deducted from Social Security.
Medicare Part B premiums are automatically deducted from your Social Security check. When Part B premiums increase faster than the COLA (as in 2026, where Part B rose 9.7% vs. a 2.8% COLA), a larger share of your raise goes to Medicare, leaving you with a smaller net increase in take-home pay.
Yes. You can review your Medicare coverage annually during the Annual Enrollment Period to find lower-cost plans, check eligibility for the Medicare Savings Program or Extra Help, manage your income to avoid IRMAA surcharges, and consider switching between Medicare Advantage and Original Medicare with Medigap depending on which offers better value for your situation.
