How It Works
This calculator determines your Medicare Part B and Part D premiums, specifically accounting for the Income-Related Monthly Adjustment Amount (IRMAA). IRMAA can significantly increase your premiums if your income exceeds certain thresholds, making this crucial for accurate financial planning in retirement.
The calculator first identifies your Modified Adjusted Gross Income (MAGI) from a previous tax year. It then compares your MAGI to the Centers for Medicare & Medicaid Services (CMS) established IRMAA brackets for the current year to determine your applicable premium surcharge.
Be sure to use your MAGI from the correct tax year (usually two years prior to the current Medicare enrollment year). Don't forget that IRMAA affects *both* Part B and Part D premiums, so factor in both surcharges for a complete picture.
Example: John's 2024 Medicare Premiums
- 1 John, single, had a 2022 Modified Adjusted Gross Income (MAGI) of $120,000. He wants to know his 2024 Medicare Part B and Part D premiums.
- 2 For 2024, a single individual with a MAGI between $103,000 and $129,000 falls into the first IRMAA bracket. This means John will pay the standard Part B premium ($174.70/month) plus an IRMAA of $69.90/month, and his Part D premium will have an additional IRMAA of $12.90/month.
- 3 John's total 2024 Medicare Part B premium will be $244.60/month ($174.70 + $69.90). His Part D premium will be his plan's base premium plus an additional $12.90/month due to IRMAA.
- 4 John's higher income significantly increases his Medicare costs. He should factor this additional expense into his retirement budget and consider strategies to manage his MAGI in future years.
