Medicare Part A & Part B Premium Estimator
Medicare premiums aren't one-size-fits-all. While most people pay a standard Part B premium, higher-income beneficiaries pay more through the Income-Related Monthly Adjustment Amount (IRMAA). This estimator uses live CMS data so you always see the most current figures.
Medicare Part A (hospital insurance) is premium-free for most Americans — if you or your spouse worked and paid Medicare taxes for at least 40 quarters (10 years). Those with fewer work credits can still buy into Part A, but will pay a monthly premium.
Medicare Part B (medical insurance) has a standard monthly premium of $185.00 in 2025, plus a $240 annual deductible. If your income exceeds certain thresholds, you'll pay more. Use the estimator below to see your projected costs based on your income.
Understanding your premiums before you enroll helps you budget accurately and compare the true cost of Medicare Advantage vs. Original Medicare + Medigap. Questions? Contact Scott for a personalized cost breakdown.
Frequently Asked Questions
What is IRMAA and how is it calculated?
IRMAA (Income-Related Monthly Adjustment Amount) is a surcharge added to your Part B and Part D premiums if your modified adjusted gross income (MAGI) exceeds certain thresholds. The SSA uses your tax return from two years prior (e.g., 2023 income affects 2025 premiums). There are five income brackets, each with a higher surcharge amount.
Is Medicare Part A really free?
For most people, yes. If you worked and paid Medicare (FICA) taxes for at least 40 quarters, your Part A premium is $0. With 30–39 quarters, you pay $285/month in 2025. With fewer than 30 quarters, the premium is $518/month. Your spouse's work record may also qualify you for premium-free Part A.
What is the Part B deductible in 2025?
The Medicare Part B deductible is $240 in 2025. After meeting this deductible, you typically pay 20% of Medicare-approved costs. Medicare Supplement (Medigap) plans can cover this 20% coinsurance, depending on the plan you choose.
Can I appeal my IRMAA surcharge?
Yes. If you had a life-changing event (retirement, divorce, death of spouse, reduced work hours) that significantly lowered your income, you can appeal your IRMAA determination with the Social Security Administration using Form SSA-44. Scott can help you understand when and how to file an appeal.
Does my Medigap premium count toward my out-of-pocket cap?
No. Medigap premiums are separate from Medicare Part B premiums and do not count toward any Medicare out-of-pocket maximum. However, Medigap plans cover most or all of your Part A and Part B cost-sharing, effectively eliminating most out-of-pocket medical expenses.
