Many retirees count on their yearly Social Security raise to help them retire comfortably and deal with rising prices. This year, the cost of living increase is 2.8%. But higher Medicare premiums may be eating into that Social Security bump. We'll explain why Medicare premiums have risen, and show you how a larger COLA can be offset by these higher deductions. This can help you stretch your retirement dollars further.

2026 Medicare premiums in numbers

The standard Part B Medicare premium is $202.90 per month, up from $185.00 in 2025. Likewise, the Part B annual deductible rose to $283, up from $257.

Almost all retirees have this premium taken directly from their Social Security checks, so the higher cost reduces the COLA they're seeing this year.

Part A, which covers hospital stays, stays premium-free for about 99% of seniors. Its deductible is $1,736 in 2026.

Medicare Part D (drug coverage) varies by plan, but the average premium is about $34.50 per month. High-income enrollees should note that IRMAA surcharges for Part D are up to $91 per month for the highest earners.

Why premiums are rising

By law, premiums must cover about 25% of Medicare Part B spending, with the rest coming from federal revenue. So when health care costs go up, Part B premiums rise to match.

Recent analyses, including work from AARP, show that medical inflation is running hotter than overall inflation. New drugs, advanced treatments, and a growing senior population add to the pressure. As these costs rise, the formulas in the Social Security Act push premiums higher.

Also, Part B and Part D come out of the Supplementary Medical Insurance (SMI) Trust Fund, which relies on premiums and general revenue rather than payroll taxes.

Each year, CMS must set premiums high enough to keep that trust fund solvent. When projected spending increases, the required premiums rise as well.

The premium hike vs. the COLA boost

The average retired-worker benefit is $2,071. That's a $56 monthly increase before Medicare from the 2025 rates.

But the $202.90 Part B premium cuts into that raise, since Medicare takes its share straight from your check. Subtract the premium hike, and the average retiree ends up with a net gain of about $39 a month.

The effect is sharper for people with smaller benefits. A 2.8% COLA on any check under roughly $640 comes to less than $17.90.

If your monthly check is around $600, the COLA comes to only $16.80, less than the premium jump. In that case, you fall under the "hold harmless" rule. You won't see your check drop, but you also won't see an increase. Your entire COLA is used to cover the Part B hike.

Higher-benefit recipients fare a little better. Someone with a $3,000 monthly check gets an $84 COLA. After subtracting $17.90 for Part B, they still clear a net raise of about $66 (assuming no IRMAA surcharges).

High-income surcharges (IRMAA)

Higher-earning retirees pay much more for Medicare in 2026. About 8% of enrollees owe Income-Related Monthly Adjustment Amounts (IRMAA) on both Part B and Part D. These are added on top of the standard premium, and they come straight out of your Social Security check.

Here's what the 2006 numbers look like:

Single filers with MAGI (Modified Adjusted Gross Income) between $109,000 and $137,000 (or $218,000–$274,000 joint) will owe an extra $81.20, bringing their total Part B premium to $284.10.
Single filers earning $137,000 to $171,000 owe a $202.90 surcharge for a total of $405.80.
At the top tier, individuals with MAGI of $500,000 or more (or $750,000+ joint) will see an IRMAA of $487.00, for a total monthly Part B premium of $689.90.

For wealthier beneficiaries, these surcharges can erase most, or even all, of the 2.8% COLA increase.

Bottom line

Rising Medicare premiums can feel discouraging, especially when you've planned around a modest COLA and hoped for a little more breathing room next year. One thing many retirees overlook, though, is how much control they still have over the rest of their health care costs and their retirement plans.

You can review your prescriptions, check your doctors' networks, and compare Medicare Advantage or Part D plans during open enrollment. Small adjustments like these can stretch your budget further and help you maintain a more stress-free retirement, even when the numbers don't break your way.
