COLA vs Medicare at every benefit level
Everyone on the standard premium pays the same dollar increase, so it takes a bigger share of a smaller check.

What you can do
- Check your notice in December. SSA's 2027 benefit notice (also in your my Social Security message center) shows the exact premium taken from your check.
- Review your drug plan during open enrollment (October 15 to December 7). Part D's deductible and out-of-pocket cap both rise in 2027, and plan premiums change every year.
- Watch the income brackets. If your 2025 income was high, an income-related surcharge (IRMAA) raises your premium; a drop in income after retirement can be appealed with SSA.

Questions people ask
What is the Medicare Part B premium for 2027?
CMS hasn't announced it yet; it usually does in November. The 2026 Medicare Trustees Report projects $209.50 a month, up $6.60 from $202.90 in 2026. We'll update this page the day CMS publishes the official amount.
How much of my COLA will Medicare take in 2027?
For the average retiree, the 3.6% COLA adds about $75.42 a month and the projected Part B increase takes $6.60 of it, about 9%. That leaves roughly $68.82 a month more in the deposit.
What is the 2027 Part B deductible?
Projected at $292, up from $283 in 2026.
What about Part D in 2027?
Already final: the Part D deductible can be up to $700 (from $615) and the out-of-pocket cap on covered drugs rises to $2,400 (from $2,100).
Can the Part B increase be bigger than my COLA?
For most people, no. A "hold harmless" rule stops the Part B increase from making your Social Security check go down, if the premium was already taken from your check. It doesn't protect new enrollees or people who pay the higher, income-based premiums (IRMAA).
