Medicare Part B Premium Calculator 2026
About the Medicare Part B Premium Calculator
Medicare Part B covers outpatient medical services, doctor visits, and preventive care. The standard 2026 premium is $185.00 per month. However, higher-income beneficiaries pay more through the Income-Related Monthly Adjustment Amount (IRMAA), which is determined by your MAGI from two years prior (2024 income affects 2026 premiums). IRMAA brackets for single filers start at $106,000 and go up to over $500,000, adding surcharges ranging from $74.20 to $450.20 per month. Married couples filing jointly have thresholds at double the single rates. Understanding your IRMAA tier is critical for retirement planning, as higher Medicare costs can significantly impact your retirement budget. Some life events may allow you to appeal your IRMAA determination.
Frequently Asked Questions
What income year is used to determine my 2026 Part B premium?
Medicare uses your 2024 tax return (MAGI) to determine your 2026 IRMAA. If your income has dropped significantly since 2024, you can file an appeal using Form SSA-44.
What is IRMAA and how does it affect my premium?
IRMAA (Income-Related Monthly Adjustment Amount) is a surcharge added to your standard Medicare Part B premium if your income exceeds certain thresholds. Higher earners pay more to help fund the Medicare program.
Does IRMAA apply to Medicare Part D as well?
Yes. IRMAA surcharges apply to both Part B and Part D (prescription drug coverage). The Part D surcharges are separate amounts based on the same income brackets.
Can I appeal my IRMAA if my income decreased?
Yes. If you experienced a life-changing event (retirement, divorce, death of spouse, etc.) that significantly reduced your income, you can appeal using SSA Form SSA-44 to have your premium recalculated based on more recent income.
Is the Medicare Part B premium deducted from Social Security?
Yes, for most beneficiaries. If you receive Social Security benefits, your Part B premium is automatically deducted from your monthly benefit payment.
