How Much Does Medicare Cost? Is It Free?
Key Points
- Most people pay $0 for Part A if they have sufficient work history.
- Part B and Part D always have monthly premiums, which may be higher based on income.
- Medigap and Medicare Advantage plans help manage out-of-pocket costs beyond premiums.
Medicare is not free — but for many people, parts of it cost nothing. Understanding what you'll pay in premiums, deductibles, and cost-sharing is essential to budgeting for retirement healthcare.
Part A Costs
Most people qualify for premium-free Part A because they or their spouse paid Medicare taxes for at least 40 quarters (10 years) while working. If you don't have enough work history, you can still purchase Part A — the premium depends on how many quarters you've earned.
Even with premium-free Part A, you're still responsible for cost-sharing when you use the coverage. Part A comes with a per-benefit-period deductible for hospital stays, and if your hospital stay extends beyond 60 days, daily coinsurance applies. These costs can add up quickly without supplemental coverage in place.
Part B Costs
Part B always has a monthly premium. The standard amount is set annually by CMS, and most beneficiaries pay it. However, if your income exceeds certain thresholds, you'll pay a higher premium through the Income-Related Monthly Adjustment Amount (IRMAA). IRMAA is based on your tax return from two years prior, which sometimes catches people off guard when income spikes in a given year.
Beyond the premium, Part B has an annual deductible. Once you meet that deductible, Medicare pays 80% of approved costs and you're responsible for the remaining 20% — with no annual out-of-pocket maximum under Original Medicare alone.
Part D Costs
Prescription drug plans (Part D) also carry monthly premiums, which vary based on the plan and the drugs you take. Like Part B, higher-income beneficiaries pay an IRMAA surcharge on their Part D premiums as well.
Each Part D plan has its own deductible, copays, and coinsurance structure depending on which tier your medications fall into. Choosing a plan based solely on the lowest premium can sometimes lead to higher total costs if your specific drugs are not well-covered on that plan's formulary.
Managing Your Out-of-Pocket Costs
The most common way to control Medicare out-of-pocket exposure is by adding either a Medicare Supplement (Medigap) plan or choosing a Medicare Advantage plan. Medigap plans pay after Medicare and can cover the 20% coinsurance, deductibles, and other gaps — providing very predictable costs. Medicare Advantage plans bundle your coverage with an annual out-of-pocket maximum, which Original Medicare does not have.
