How much will my parent pay for Medicare Part B in 2027?
In 2026, most people pay $202.90 a month for Part B. The 2027 amount is announced in November. Medicare's Trustees estimated $209.50 a month, but the final amount may differ.
Will my parent pay more because of their income?
Some people with higher income pay more each month. This extra amount is called the income-related monthly adjustment amount (IRMAA). Social Security sets it from the income on a federal tax return. It is added to both the Part B premium and the drug plan premium.
The table below shows the amounts for each income range. If you think your parent's amount is wrong, contact Social Security.
What if my parent signed up for Part B late?
If your parent could have signed up for Part B but did not, they may pay a late penalty. It adds 10% for each full 12 months they could have had Part B but did not. They pay it for as long as they have Part B.
Some people do not owe it, such as people who had health coverage from a current job. Retiree coverage and continued job coverage (COBRA) don't count. Social Security decides. The table below shows what the penalty adds to the usual premium.
When will the 2027 amount be known?
Medicare announces next year's Part B premium and deductible in the fall, usually in November. We update this page when Medicare publishes them.
