Percentage Increase:(185.00 - 174.70) / 174.70 * 100 = 5.89%
But official CMS figures set the standard monthly premium at $185.00 for 2025, which is a $10.30 increase from 2024 – source: CMS.
Additional notes:
- Higher-income beneficiaries pay more, ranging from $259.00 to $628.90 per month, based on income – source: RRB.
- Some may pay less if protected by the “hold harmless” provision, which limits premium increases to the Social Security cost-of-living adjustment – source: UHC.
- These figures apply to Part B; costs for other Medicare parts vary – source: PeopleKeep.
With Medicare Part B premiums rising about 5.9% in 2025, the new standard monthly cost is $185.00. source: CMS.
