How much does Medicare Part B cost?

Q: How much does Medicare Part B cost the insured?

2020 Medicare premiums, deductibles, costsA: In 2020, most people earning no more than $87,000 ($174,000 for a married couple; note that these amounts are higher than they were prior to 2020) pay $144.60/month for Part B. And in most cases, Part B premiums are just deducted from beneficiaries’ Social Security checks.

Part B premium can be limited by Social Security COLA, but that wasn’t an issue for most beneficiaries in 2020

In 2020, most enrollees are paying $144.60/month for Part B, which is the standard amount. Most enrollees were also paying the standard amount ($135.50/month) in 2019. But that’s in contrast with 2017 and 2018, when most enrollees paid a premium that was lower than the standard premium. The standard premium in 2018 was actually $134/month, but the cost of living adjustment for Social Security wasn’t quite large enough to cover all of the increase from 2017’s premium for most enrollees. That’s why most people paid about $130/month.

The standard Part B premium increased by about $9/month in 2020. But the 1.6 percent Social Security COLA for 2020 increased the average beneficiary’s Social Security benefit by $24/month. Since the COLA for most beneficiaries exceeded the premium increase for Part B, most Part B enrollees are paying the standard premium in 2020. [If the COLA wasn’t sufficient to cover the Part B increase, the average enrollee would be charged a lower-than-standard premium for Part B in order to avoid a year-over-year decrease in their net Social Security check after the Part B premium is subtracted each month.]

Higher premiums for enrollees with high-income (and the threshold for that is higher in 2020)

Since 2007, people who earn more than $85,000 ($170,000 for a couple) have paid higher Part B premiums (and higher Part D premiums) based on their income. These beneficiaries paid Part B premiums that ranged from $189.60/month to $460.50/month in 2019.

For the first time, the threshold for what counts as “high income” was adjusted for inflation as of 2020, increasing it to $87,000 for a single individual and $174,000 for a couple. Harry Sit, of The Finance Buff, explains how the inflation indexing works here.

Indexing the high-income threshold: The math
The indexing is based on the percentage by which the average of the Consumer Price Index for Urban consumers (CPI-U) for the 12-month period ending in the most recent August exceeds the average of the 12-month period that preceded that. So for 2020, we look at how the average CPI-U from September 2018-August 2019 exceeded the average CPI-I from September 2017-August 2018.

On this page, you can pull up the data for CPI-U (select the first box under “Price Indexes”) and manually calculate how the average CPI-U has changed. You’ll add up all the numbers from September 2017 through August 2018 (don’t include the “Half1” and “Half2” numbers), and divide by 12 to get the average (in this case, 294.28). Then you’ll do the same thing for September 2018 through August 2019 (you’ll get an average of 254.016). The difference between those two numbers is 4.736, which is 1.9 percent higher than 294.28. So as Harry explains here, we increase 85,000 by 1.9 percent — which results in 86,615 — and then round to the nearest $1,000. That gives us an income threshold of $87,000, which is the lower bound of “high-income” as of 2020.

For people with income above $87,000 ($174,000 for a couple) in 2020, Part B premiums for 2020 range from $202.40/month to $491.60/month.

2020 premium surcharge is based on 2018 tax return; you can appeal it if your income has changed

The government determines whether you have to pay an income-related premium surcharge based on your income tax return from two years ago, since that is the most recent tax return they have on file at the start of the plan year. [2018 tax returns were filed in 2019, so those were the most current returns available when income-related premium adjustments were determined for 2020.]

But if a life-change event has subsequently reduced your income, there’s an appeals process you can use. In the appeal, you can request that the income-related premium adjustment be changed or eliminated without having to wait for it to reflect on a future tax return.

Part B deductible also increased for 2020

Medicare B also has a deductible, which is $198 in 2020, up from $185 in 2019. After the deductible is met, the enrollee is generally responsible for 20 percent of the Medicare-approved cost for Part B services. But supplemental coverage (from an employer-sponsored plan, Medigap, or Medicaid) often covers these coinsurance charges.

For people who became eligible for Medicare before the start of 2020, there are Medigap plans available (Plans C and F) that cover the Part B deductible, in addition to coinsurance charges. But those plans are not available for newly-eligible Medicare beneficiaries after the end of 2019.

My wife and I started Social Security around November 2019. I retired in 2018 and my wife has not earned an income for some years. We had a high income in 2017, so I received a letter from SS that I have a high premium amount for Medicare B and D that will be deducted from 2020 SS based on our joint income in 2017. However my wife received the same letter with the same amounts. Isn’t this double dipping by SS?? Shouldn’t we be paying one amount for our earned joint income instead of paying 2x for a joint income?

Medicare sends notices to each person about their coverage and premiums. Because it sounds like you’ll each have a higher premium due to income, you’ll both receive notices about your costs.

Please note the government can sometimes adjust income-related Medicare premiums based on life circumstances, such as retiring. If retirement means your current income is lower than in 2017, you may be able to appeal that higher premium. More information can be found here:

I will be 65 next month and I have no income and am single. My age to get social security isnt until 66 and 2 months. So with no income and no social security money until then how do I pay for medicare part B? If I dont sign up for it I get charged penalties! I will not be forced to file early social security with 25% less monthly. How is this legal when the government is who upped my retirement age! I could apply for welfare to help with part B but only if I take early social security now at almost $300 a month less. The government should not force us to take early social security by fining us for not applying when they are the ones who changed our age requirements! !!

Depending on your new income, you might qualify for one of the Medicare Savings Programs that can cover your Part B premium: You’ll want to contact your state Medicaid office (Medicare Savings Program funding comes from the state’s Medicaid program) to see if you qualify.
You can also reach out to the State Health Insurance Assistance Program in your state: These offices provide help and advice for Medicare beneficiaries.
