Watching the fall release
2027 Medicare premiums: what’s known now, and when the number drops
Short answer: CMS has not announced 2027 premiums yet. The announcement typically lands in the fall; the 2026 figures arrived November 14, 2025. This page explains the formula that produces the number, what the last three years suggest, what’s already scheduled to change in 2027, and the moves worth making before the release. We update it within days of the official announcement.
Key takeaways
- The 2027 Part B premium is not yet announced; CMS releases the figures in the fall (the 2026 release came November 14, 2025).
- The recent trend: $174.70 (2024), $185.00 (2025), $202.90 (2026), increases of 5.9% and then 9.7%.
- The premium is set by formula: enrollees pay roughly 25% of projected Part B program costs.
- Already scheduled for 2027: the Part D out-of-pocket cap adjusts with inflation, IRMAA brackets index, and the GLP-1 Bridge runs through December 31, 2027.
- Your fall to-do list doesn’t depend on the number: the enrollment window is October 15 to December 7 regardless.
When the announcement comes
CMS publishes the next year’s Part B premium, Part B deductible, and Part A cost-sharing in a fall announcement, accompanied by a Federal Register notice. Recent releases have landed between mid-October and mid-November; the 2026 figures arrived November 14, 2025, later than usual because of the government shutdown. The awkward part of the calendar: open enrollment starts October 15, so in some years people begin shopping before the standard premium is public. Plan-specific premiums for Advantage and Part D, however, are loaded into the plan finder by early October regardless.
When the 2027 release happens, this page gets the official numbers within days, with the same sourcing standards as our 2026 premium breakdown.

Two increases don’t make a law of nature, and we won’t pretend to forecast the 2027 number. What the trend does justify is planning your budget with headroom rather than assuming a flat year, and treating any specific "2027 premium" figure you see before the CMS release as marketing, not fact.
How the number is actually set
The Part B premium isn’t negotiated or voted on each year; it falls out of a formula. Enrollee premiums are set to cover roughly 25% of projected Part B program costs for the coming year, with general revenues covering the rest. When projected spending on physician services, outpatient care, and Part B drugs rises, the premium follows arithmetically. That’s why single policy changes can move the number visibly: CMS noted the 2026 premium would have been about $11 higher without a rule cutting skin-substitute spending. Two other mechanics ride along: the hold-harmless rule limits most current enrollees’ dollar increase to their Social Security COLA increase, and IRMAA brackets re-index annually, so the income cliffs move a little each year too.
What’s already known for 2027
- The Part D out-of-pocket cap adjusts with inflation. It went $2,000 (2025) to $2,100 (2026) and will index again for 2027; the exact figure arrives with the fall Part D parameters.
- The GLP-1 Bridge runs through December 31, 2027, at its flat $50 monthly copay, unless CMS changes course. Its planned Part D successor remains delayed indefinitely. (Full explainer.)
- The calendar holds: ANOCs in September 2026, enrollment October 15 to December 7, 2027 coverage effective January 1.
- Standardized Medigap benefits don’t change, though the high-deductible Plan G amount and individual insurer premiums re-set annually.
What to do while you wait
- Nothing premium-dependent. Your October checklist (here) is identical whether the 2027 premium rises $8 or $18: read the ANOC, check doctors, run the drug list.
- If you’re near an IRMAA cliff, remember 2027 surcharges will key off your 2025 tax return, and income moves you make in 2026 (Roth conversions, asset sales) land on your 2028 premium. The cliff structure is explained in the premium article.
- If you’re turning 65 before the announcement, enroll on your normal schedule; premiums adjust automatically each January and waiting for the number is never worth a late-enrollment penalty.
