How much is Medicare Part B?

A premium is the amount you pay each month to keep the coverage. Most people pay this standard amount, but if your income is above a certain level, you may pay more through IRMAA, the Income-Related Monthly Adjustment Amount, which is an extra charge based on your reported income. IRMAA starts for single filers with income above $109,000 and joint filers above $218,000 in 2026. Part B also has a yearly deductible of $283 in 2026, which you pay before Medicare begins sharing costs. So the $202.90 is the baseline; higher earners pay more, and the deductible is separate from the monthly premium.
