What Is the Cost of Medicare Part B for 2025?
The Medicare Part B premium is the monthly cost when you have Original Medicare (Parts A and B). It’s income-based and changes each year. To illustrate, here’s how the 2024 Medicare Part B premium compares to prior years:
- Medicare Part B premium 2022: $170.10 and up
- Medicare Part B premium 2023: $164.90 and up
- Medicare Part B premium 2024: $174.70 and up
- Medicare Part B premium 2025: $185 and up
Your Medicare Part B premium is just one of the costs you’ll end up paying. How much is Medicare Part B overall? That depends; your Part B premium may go up if your income is high enough, and several other costs will also factor into what you pay. These include your deductible and out-of-pocket costs like coinsurance and copayments.
What Is the Maximum Cost of Medicare Part B?
Typically, the cost of your Medicare Part B coverage comes down to several costs, starting with your monthly premium and annual Medicare Part B deductible. After your deductible is paid, you’ll need to pay coinsurance for each visit or service. This is often 20% of the Medicare-approved cost. Original Medicare does not have an out-of-pocket maximum, so there’s no limit to how much you could end up paying for Medicare Part B.
Your cost may go up even more if you don’t sign up for Medicare when you’re first eligible; Medicare Part B has a 10% penalty for every 12-month period you weren’t enrolled in Medicare but were eligible. You’ll pay this enrollment penalty as long as you’re enrolled in Part B.
There are options for lowering the overall cost of Medicare Part B. Medicare Supplement Insurance (Medigap) has several policies that will help cover your Part B costs, including premiums, deductibles and out-of-pocket costs. Medicare Advantage (Part C) is Medicare coverage offered by private insurance companies and often has different costs for Part B coverage than Original Medicare.

How Is Your Medicare Part B Premium Calculated?
The Medicare Part B premium changes each year and is calculated based on data collected by the Centers for Medicare and Medicaid Services (CMS). The standard amount for Part B coverage in 2025 is $185 per month.
If your income is high enough, you may pay more for your Part B premium each month. Medicare measures your modified adjusted gross income to determine your income level. Depending on how much money you make, you may have to pay an Income Related Monthly Adjustment Amount (IRMAA) on top of your Part B premium. While most people pay the standard amount, an IRMAA can make your premium payment balloon up to as much as $628.90 per month.
Medicare provides IRMAA limits for adults who are:
- Single
- Married couples who file jointly
- Married couples who file separately

How Do I Pay My Part B Premium?
Your Medicare Part B premium is a monthly payment. It may be deducted automatically for you if you receive the following benefits:
- Social Security
- Railroad Retirement Board (RRB)
- The Office of Personnel Management (federal government)
If you don’t receive any of these benefits, you may be responsible for paying your Part B premium each month.
What Is the Medicare Part B Deductible for 2024?
Your deductible is the amount you must pay out-of-pocket before Medicare begins to pay its portion. After you’ve met your deductible each year, you then pay coinsurance for each Medicare-approved service you receive. Like the premium, the Part B deductible can change each year. Here’s the most recent deductible amount compared to prior years:
- Medicare Part B deductible 2021: $203
- Medicare Part B deductible 2022: $233
- Medicare Part B deductible 2023: $226
- Medicare Part B deductible 2024: $240
Unlike the Part B premium, this amount isn’t based on income. Everyone enrolled in Original Medicare pays the same Part B deductible. That means no matter how high your income is, you’ll pay the standard Medicare Part B deductible amount.
Medicare Part B Coverage & Enrollment
When it comes to Medicare, Part B is a big part of what comes to mind when older Americans think about their medical coverage. Medicare Part B covers the medical services you need and, along with Part A (hospital services), provides the foundation of Original Medicare.
But Part B coverage isn’t exclusive to Original Medicare; you’ll receive at least the same benefits with Medicare Advantage (Part C). It replaces Original Medicare (Part A & B), but offers the same Part A and B benefits or coverage as Original Medicare. Along with receiving Part A and B benefits, Medicare Part C often bundles additional services like dental, hearing, vision and prescription drug coverage.
What Does Medicare Part B Cover Exactly?
Medicare Part B generally covers the medical treatments you receive. But Part B won’t cover everything — your treatments or services must either be:
- Medically necessary: Your doctor must deem your treatment is required to improve or maintain your health.
- Preventive services: Medicare-approved screenings and other preventive services are covered and generally at no-cost
Part B can also cover wheelchairs and other medically necessary equipment. Items like these are known as durable medical equipment.
How to Enroll in Medicare Part B?
Are you or a loved one turning 65 and looking to enroll in Medicare? You’ll want to know when to enroll, and how. As a starting point, find your Initial Enrollment Period (IEP) and mark it on your calendar. This is your first chance to sign up for Medicare. It’s a seven-month window that begins three months before your birth month. Enrolling in Part B during your IEP can pay off — enrolling late means you could be stuck paying late enrollment penalties for as long as you have a Part B plan.
There’s plenty more to know about enrolling in Medicare Part B, including how to sign up and what your options are.
FAQ
How does Medicare calculate my Part B premium and Income Related Monthly Adjustment Amount (IRMAA)?
When you enroll, your IRMAA, if you pay one, will be based on your tax returns from two years prior. That year’s income will be used to determine how much IRMAA you’ll have to pay each month on top of your Part B premium. For example, 2025 Part B premiums are based on 2023 tax returns.
Do Part B costs remain the same after I enroll? Or do they increase each year?
If I enroll in Medicare Advantage, will I still pay a Part B premium?
Whether you choose Original Medicare (Parts A and B) or Medicare Advantage, you’ll receive at least the same level of care; Medicare Advantage must match Part B’s coverage, but often offers more benefits.
