Quick answer: The 2027 Medicare Part B premium requires a different check from the Social Security COLA. On October 22, 2026, Medicare.gov’s cost page checked for this article still listed the 2026 standard Part B premium of $202.90. We did not verify a finalized 2027 standard premium there. Treat a projected 2027 amount as an estimate, not your personal bill.

2027 Medicare Part B premium: confirmed versus projected
| Item | Status |
|---|---|
| 2026 standard monthly Part B premium | $202.90 |
| 2026 annual Part B deductible | $283 |
| 2027 standard Part B premium | Final amount not verified in the official pages checked |
| 2027 Social Security COLA | 3.6%, confirmed by SSA |
Sources: CMS’s 2026 premium fact sheet, Medicare.gov costs and SSA’s 2027 COLA information. A deductible is not another monthly premium.
How much of a COLA reaches your deposit?
Use a simplified hypothetical example: a $2,000 gross monthly Social Security benefit increased by 3.6% becomes $2,072, a $72 gross increase. If Part B is deducted, the change after that deduction depends on the change in the premium—not just its new level.
Illustrative monthly change after Part B = $72 − (assumed new premium − $202.90).
| Assumed new monthly premium | Premium increase | Change after Part B |
|---|---|---|
| $202.90, unchanged scenario | $0 | +$72.00 |
| $210.00, assumed | $7.10 | +$64.90 |
| $220.00, assumed | $17.10 | +$54.90 |
These are arithmetic scenarios, not SSA benefit calculations. They omit benefit-rounding rules, income-related adjustments, other deductions, individual protections and circumstances. They do not predict anyone’s actual deposit. The point is to avoid subtracting the entire new premium from the COLA while forgetting the premium already being paid.
Do not confuse Part B with a Medicare Advantage plan premium
CMS’s September 28 release concerns 2027 Medicare Advantage and Part D plans. Those plan figures are not the standard Part B rate. Medicare.gov explains that Medicare Advantage enrollees must keep paying Part B; check any plan-specific premium reduction rather than assuming a low advertised plan premium eliminates that obligation.
A four-item open-enrollment checklist
- Separate the columns. List Part B, plan premiums and expected out-of-pocket costs individually.
- Check your documents. Read the Annual Notice of Change and the plan’s benefit summary, not just a national average.
- Verify the practical coverage. Compare the providers, prescriptions and pharmacies relevant to your needs using official plan information.
- Use the correct window. CMS lists October 15–December 7, 2026 for the fall health/drug-plan comparison period. Do not assume this is everyone’s initial Part B enrollment window.

Frequently asked questions
Is a 2027 premium estimate my confirmed charge?
No. Check the final official rate and your own notice before treating it as a personal charge. Your own notice matters because the standard premium may not reflect income-related adjustments or any enrollment penalties applicable to you.
Does a 3.6% COLA mean my bank deposit rises exactly 3.6%?
Not necessarily. A gross benefit adjustment and a deposit after deductions are different calculations.
