How Much Did Medicare Go Up in 2025
For 2025, the standard Medicare Part B premium increased to $185 per month, up from $174.70 in 2024. The Part B annual deductible rose to $257, also an increase from the prior year. These adjustments reflect a combination of statutory formulas and projected program costs, and they affect most retirees who do not have premium-free Part A or who pay Income-Related Monthly Adjustment Amounts.

Part A Costs Also Shifted
Most beneficiaries pay no monthly premium for Medicare Part A, but hospital and skilled nursing facility cost-sharing went up. The inpatient hospital deductible for each benefit period reached $1,676 in 2025, and coinsurance amounts for days 61 through 90 and beyond also increased. The Part A deductible applies per benefit period, not per calendar year, which can affect how often you hit the threshold.
Who Pays More Because of Income
Higher-income beneficiaries pay an Income-Related Monthly Adjustment Amount, or IRMAA. The thresholds for these tiers are based on modified adjusted gross income from two years prior. In 2025, the income brackets and premium tiers for Part B changed, meaning some enrollees see larger jumps than the standard increase. The Social Security Administration mails IRMAA letters before the premium is deducted.
Why Medicare Costs Rise Each Year
Medicare premium increases are driven by several factors, including overall healthcare inflation, utilization trends, and changes in the program's financing structure. Congress sets the rules, and the trustees report projects how the Hospital Insurance trust fund will perform over a 75-year horizon. Premium adjustments are meant to keep the program solvent, even if they strain beneficiary budgets.
What to Watch for Each Year
The Centers for Medicare & Medicaid Services publishes the annual premium and deductible figures during the fall, ahead of the Open Enrollment period that runs from October 15 through December 7. Beneficiaries can review their Medicare Summary Notice and compare plans during this window. If a premium increase appears on your Social Security check, it is typically reflected in the annual notice mailed in early December.

Where to Get the Official Numbers
Always confirm current premiums on the official Medicare.gov site or in your Social Security benefit letter. The figures above come from the CMS annual announcement and the Social Security Administration's 2025 cost-of-living adjustments. If your situation is unusual — for example, you have a Medicare Savings Program or a Medicare Advantage plan with different cost-sharing — the standard increases may not apply to you directly.
