Medicare Premium Calculator
Medicare can be complicated, especially when it comes to understanding your monthly and annual premium costs. Factors like your income, tax filing status, work history, and the parts of Medicare you’re enrolled in can all affect the amount you pay. To help simplify this, our Medicare Premium Calculator provides an easy way to estimate your Medicare Part A, Part B, and Part D premiums based on your personal financial and enrollment details.
Whether you are new to Medicare or reassessing your healthcare budget, this tool gives you a clear breakdown of your premiums and how income-related adjustments may impact your costs. Understanding these numbers can help you plan better for your healthcare expenses.
What Is the Medicare Premium Calculator?
The Medicare Premium Calculator estimates the monthly and annual premiums for Medicare Parts A, B, and D based on:
- Your tax filing status (individual, joint, or married filing separately)
- Your Modified Adjusted Gross Income (MAGI) from two years ago
- Your Social Security work credits which affect Part A premiums
- Which Medicare parts you’re enrolled in (Parts A, B, D)
- Your coverage period (how many months you want to calculate for)
- Your chosen Part D prescription drug plan premium (if applicable)
The calculator also accounts for Income-Related Monthly Adjustment Amounts (IRMAA), which increase Part B and Part D premiums for individuals with higher incomes.
How to Use the Medicare Premium Calculator
Using this tool is straightforward. Here’s a step-by-step guide:
- Select Your Tax Filing Status: Choose your filing category — Individual, Married Filing Jointly, or Married Filing Separately.
- Enter Your Modified Adjusted Gross Income (MAGI): Input your MAGI from two years ago, which Medicare uses to determine income-based surcharges.
- Select Your Work Credits: Your work history determines your Part A premium. Choose among 40+ credits (premium-free), 30-39 credits (reduced premium), less than 30 credits (full premium), or if your spouse has 40+ credits.
- Choose Medicare Parts Enrolled: Part A is usually premium-free with enough work credits and is pre-selected. Check whether you have Part B (medical) and/or Part D (prescription drug) coverage.
- If You Have Part D: Enter your monthly premium for your prescription drug plan, if known.
- Select Coverage Period: Specify the number of months you want to calculate for (e.g., full year or fewer months if you had partial coverage).
- Click Calculate: The calculator will provide your income bracket, monthly premiums for each part including IRMAA surcharges if applicable, and total costs for the selected period.
Example Calculation
Let’s say Mark, an individual filer, has the following details:
- MAGI: $140,000 (from two years ago)
- Work Credits: 40+ (premium-free Part A)
- Enrolled in Parts A, B, and D
- Part D Monthly Premium: $40
- Coverage Period: Full Year (12 months)
Calculation Results:
- Income Bracket: $129,001 – $161,000
- Part A Monthly Premium: $0 (premium-free due to work credits)
- Part B Monthly Premium: Base $174.70 + IRMAA $174.70 = $349.40
- Part D Monthly Premium: $40 + IRMAA $33.30 = $73.30
- Total Monthly Premium: $0 + $349.40 + $73.30 = $422.70
- Total Annual Cost: $422.70 × 12 = $5,072.40
This gives Mark a clear picture of his expected Medicare costs based on his income and coverage.
Important Information About Medicare Premiums
- Part A Premiums: Usually premium-free if you or your spouse worked 40 or more quarters (about 10 years). Otherwise, you pay a monthly premium that varies based on work credits.
- Part B Premium: Most people pay a standard premium ($174.70 in 2024), but higher-income beneficiaries pay additional surcharges (IRMAA).
- Part D Premium: Prescription drug coverage premiums vary by plan. High-income individuals may also pay an IRMAA surcharge on top of their base Part D premium.
- Income-Related Monthly Adjustment Amount (IRMAA): Applies to both Parts B and D premiums if your MAGI exceeds certain thresholds. IRMAA is based on tax returns from two years prior.
- Coverage Period: This tool allows you to calculate premiums for less than a full year, useful if you enrolled or terminated coverage mid-year.
- Tax Filing Status: Medicare uses your tax filing status to determine income brackets for IRMAA surcharges, affecting your premiums.
- Work Credits: Your Social Security work credits affect whether Part A is premium-free or if you pay reduced/full premiums.
