Medicare Advantage Premiums 2027: CMS Projects a 16.5% Drop

Answer first: CMS projects the weighted average monthly Medicare Advantage premium to fall 16.5%, from $14.37 in 2026 to about $12 in 2027. That is a national projection, not a quote for your plan. Premiums, deductibles, drug costs, provider networks, supplemental benefits and income-related charges still vary by county and plan.

What the CMS projection actually means

The weighted average is calculated across plans and enrollment, so it is useful for a national trend but not a personal bill. A $0 premium plan can still have cost sharing when you use care, and a plan with a monthly premium may have a lower deductible or richer network. Compare estimated annual cost instead of stopping at the headline premium.

Why plan-level costs can move differently

Medicare Advantage organizations submit bids and benefit packages for each service area. CMS projects average premiums, but your county may add or remove plans, change star-rating bonuses or alter supplemental benefits. A plan’s medical network and prior-authorization rules can matter more than a small premium difference.

Part D and drug coverage are part of the decision

CMS also projects lower average prescription-drug premiums inside Medicare Advantage plans. Stand-alone Part D premiums are a separate market and should be compared independently. Enter every prescription, dosage and preferred pharmacy in Medicare Plan Compare before enrolling.

How to compare during Open Enrollment

Medicare Open Enrollment generally runs October 15 through December 7 for coverage beginning January 1. Save your current plan’s Annual Notice of Change, compare the new premium and maximum out-of-pocket limit, and verify doctors, hospitals and pharmacies. If a medication is placed on a different tier, the annual cost can change even when the premium falls.

Build the cost into a retirement budget

Use the USFinNexus budget calculator to reserve room for premiums, copays, dental or vision costs and an emergency medical buffer. The retirement calculator can model withdrawals, but it cannot determine plan eligibility or network coverage. Medicare.gov and the plan’s Evidence of Coverage control the final terms.

What the projection does not promise

The CMS number is not a guarantee that every beneficiary will pay less. Income-related adjustments, late-enrollment penalties, Medigap premiums and services outside the plan can increase total spending. Treat the projection as a reason to compare, not as a reason to switch without checking doctors and prescriptions.

2027 decision worksheet

Start with the plan you have now, not with a generic national average. Write down the current premium, annual deductible, maximum out-of-pocket limit, primary-care copay, specialist copay and the names of the doctors you actually use. Then compare those same fields in every 2027 option. This side-by-side method prevents a low premium from hiding a much higher cost when you need care.

Next, run your regular prescriptions through the official comparison tool using the exact dose and pharmacy. Save the result as a PDF or screenshot because formularies and preferred pharmacies can change. If a medication is expensive, call the plan and ask about prior authorization, step therapy, quantity limits and the coverage exception process. A plan that looks cheap without those details may be the most expensive choice for your household.

Finally, price the non-premium costs you can realistically face. Include dental or vision limits, transportation, hearing benefits, home-care rules and the amount you would need in a bad medical year. Put that range into your budget rather than assuming every supplemental benefit has cash value. The best plan is the one whose network and cost-sharing you can use, not simply the plan with the largest headline benefit.

Three checks before you act

First, confirm the fact that drives the decision in the primary document, not in a headline or social post. A national average, projected rate, calendar date or tax threshold can be useful context but may not be the number that applies to your household. Save the source URL, publication date and the assumptions you used so you can explain the decision later.

Second, run a downside scenario. Ask what happens if the premium rises, a payment arrives late, the market moves against you, a rate increases, a prescription changes tiers or your income is higher than expected. A plan that works only under the best case is not a durable plan. Put the conservative result into your cash budget before committing.

Third, check the operational deadline. a Medicare plan can fail because a custodian, lender, insurer, agency or plan has a cutoff earlier than the public due date. Start paperwork early, verify the receiving account or provider, and keep a confirmation number. If two documents conflict, use the official agency or plan contact and ask for a written answer.

Finally, separate education from a personal recommendation. This guide explains the framework and links to official rules; it cannot see your complete income, medical history, loan file, account basis or state law. A qualified professional can review those facts and document a choice that is appropriate for you.
