Medicare costs are set to climb again in 2027, though most beneficiaries will see a smaller premium jump than the steep increase between 2025 and 2026. Based on the 2026 Medicare Trustees Report, the standard Part B premium is projected to rise to approximately $209.50 per month in 2027, up from the confirmed $202.90 in 2026. On the prescription drug side, changes are already finalized: the Part D annual out-of-pocket cap increases to $2,400 and the standard Part D deductible rises to $700 for 2027. Below is a full breakdown of what is confirmed, what is still projected, and what drives these numbers.
A quick note on terminology before the tables. Some 2027 figures are already locked in by CMS through the Contract Year 2027 Part D final rule and the annual inflation-indexing formulas written into law. Others, specifically the Part B premium, the Part B deductible, and the Part A hospital deductible, will not be officially announced until around November 2026. Where a number is a projection, we say so. Where it is finalized, we say that too.
Projected 2027 Medicare Costs at a Glance
| Cost | 2026 (confirmed) | 2027 (projected or finalized) | Status |
|---|
| Part B standard premium (monthly) | $202.90 | ~$209.50 | Projected (Trustees Report) |
| Part B annual deductible | $283 | ~$292 (estimate) | Projected |
| Part A hospital deductible | $1,736 | Not yet announced | Pending (November) |
| Part D standard deductible | $615 | $700 | Finalized |
| Part D out-of-pocket cap | $2,100 | $2,400 | Finalized |
The Part B premium projection of $209.50 represents roughly a 3.3% increase, which would be the smallest percentage rise since 2023. For context, the premium jumped from $185.00 in 2025 to $202.90 in 2026, an increase of nearly 10%. So 2027 looks comparatively mild, at least for the base premium.
Part B Premium 2027: What to Expect
The standard Medicare Part B premium covers doctor visits, outpatient care, durable medical equipment, and many preventive services. Most beneficiaries pay the standard premium, which is deducted directly from their Social Security check.
For 2027, the 2026 Trustees Report projects the standard premium at approximately $209.50 per month. That is a projection, not a final figure. CMS sets the official number each fall based on actual spending data and utilization trends. The final 2027 premium could land slightly above or below $209.50 depending on how medical costs come in during 2026.
It is worth noting that the Trustees also project premiums rising faster in the years after 2027. The average annual increase over the following eight years is expected to be more than double the 2027 bump, driven by higher healthcare utilization, rising provider payments, and demographic shifts as more people age into Medicare.
Higher-Income Beneficiaries and IRMAA
If your income exceeds certain thresholds, you pay an Income-Related Monthly Adjustment Amount, or IRMAA, on top of the standard Part B premium. IRMAA is based on your modified adjusted gross income from two years prior, so your 2027 surcharge depends on your 2025 tax return.
The projected 2027 IRMAA thresholds are expected to begin at approximately $112,000 for single filers and $224,000 for married couples filing jointly, though official brackets are released in November. Beneficiaries above these thresholds pay progressively higher premiums across five income tiers. The highest earners can pay several times the standard premium.
Part B Deductible 2027
The annual Part B deductible was $257 in 2025 and rose to $283 in 2026. For 2027, no official figure has been released yet. Based on the recent trend of roughly 3% to 10% annual increases and the projected premium growth, the 2027 Part B deductible is estimated to land around $290 to $295, or approximately $292. Treat that as an estimate, not a confirmed number. Once you meet the deductible, you typically pay 20% of the Medicare-approved amount for most covered services.
Part A Costs 2027
Part A covers inpatient hospital stays, skilled nursing facility care, hospice, and some home health care. Most people do not pay a Part A premium because they or a spouse paid Medicare taxes for at least 40 quarters (10 years) of work.
The official 2027 Part A figures will be announced around November 2026. For reference, here are the confirmed 2026 amounts, which give a reasonable baseline for what 2027 will look like after a typical annual increase:
| Part A cost | 2026 (confirmed) |
|---|
| Inpatient hospital deductible (per benefit period) | $1,736 |
| Days 61 to 90 coinsurance (per day) | $434 |
| Lifetime reserve days coinsurance (per day) | $868 |
| Skilled nursing facility days 21 to 100 (per day) | $217 |
| Part A premium, 30 to 39 quarters of work | $311/month |
| Part A premium, fewer than 30 quarters | $565/month |
The Part A hospital deductible rose $60 between 2025 and 2026 (from $1,676 to $1,736). A similar or slightly larger increase for 2027 would put the deductible in the neighborhood of $1,780 to $1,810, though the official figure will depend on hospital cost trends.
Part D Prescription Drug Costs 2027
This is the area with the most certainty for 2027, because CMS finalized the Contract Year 2027 Part D parameters in its April 2026 final rule.
Two numbers matter most. First, the annual out-of-pocket cap on covered prescription drugs rises from $2,100 in 2026 to $2,400 in 2027. This cap, created by the Inflation Reduction Act, means that once your out-of-pocket drug spending hits $2,400, you pay nothing more for covered medications for the rest of the year. Second, the standard Part D deductible increases from $615 in 2026 to $700 in 2027.
| Part D cost | 2026 | 2027 (finalized) |
|---|
| Standard deductible | $615 | $700 |
| Annual out-of-pocket cap | $2,100 | $2,400 |
These are the parameters for the standard defined benefit. Actual plan premiums, deductibles, and formularies vary by plan and region, and many plans differ from the standard structure. Higher-income beneficiaries also pay a Part D IRMAA surcharge, which is added to the plan premium and follows the same income thresholds as the Part B surcharge.
The Medicare Prescription Payment Plan, which lets beneficiaries spread out-of-pocket drug costs into monthly installments over the calendar year, continues in 2027. It does not lower your total cost, but it can smooth out large upfront pharmacy bills.
What Is Driving the 2027 Increases
Several factors push Medicare costs higher each year:
- Rising healthcare utilization. Beneficiaries are using more outpatient services, and assumed utilization increases consistent with historical patterns feed directly into premium calculations.
- Higher provider payments and medical prices. Physician and outpatient facility costs climb over time, and Part B premiums are set to cover roughly 25% of expected program costs.
- Demographic shifts. As the population ages and more people enroll, total program spending rises.
- Inflation indexing. The Part D deductible and out-of-pocket cap are indexed to grow with prescription drug cost growth, which is why the cap moves from $2,100 to $2,400.
One factor that slightly restrained the 2026 premium was a CMS policy change targeting spending on skin substitutes, which is projected to cut that spending sharply. Absent that action, the 2026 premium increase would have been higher, and similar policy decisions can influence the final 2027 figure.
How to Plan for 2027 Medicare Costs
Budgeting for Medicare is easier when you separate the confirmed numbers from the estimates. The Part D cap and deductible are set. The Part B premium is a strong projection. The Part A figures and Part B deductible are still pending.
A few practical steps:
- Watch for the November announcement. CMS releases official 2027 Part A and Part B figures in the fall, usually mid-November. That is when the projected premium becomes final.
- Check your income against IRMAA thresholds. Because 2027 surcharges are based on your 2025 income, you may already know whether you cross a bracket. Life changes like retirement can qualify you to request a reduction.
- Review your Part D plan during Open Enrollment. The annual Medicare Open Enrollment period runs October 15 to December 7. With the deductible rising to $700, comparing plans on formulary and total cost matters more than premium alone.
- Factor in the $2,400 drug cap. If you take expensive medications, the cap limits your annual exposure, and the payment plan can spread it across the year.
If you or a household member is approaching age 65 or managing Medicare costs alongside other expenses, it is worth checking whether you qualify for programs that help cover premiums and out-of-pocket costs, such as a Medicare Savings Program or Extra Help for prescription drugs. These programs have income and asset limits and can significantly reduce what you pay.
Frequently Asked Questions
How much will Medicare Part B cost in 2027?
The standard Part B premium is projected at approximately $209.50 per month in 2027, up from $202.90 in 2026, according to the 2026 Medicare Trustees Report. This is a projection. CMS will announce the official 2027 premium around November 2026, and the final number could be slightly higher or lower.
What is the Part D out-of-pocket cap for 2027?
The Part D annual out-of-pocket cap rises to $2,400 in 2027, up from $2,100 in 2026. This figure is finalized. Once your out-of-pocket spending on covered drugs reaches $2,400, you pay nothing more for covered medications for the rest of the calendar year.
What is the Medicare Part D deductible in 2027?
The standard Part D deductible increases to $700 in 2027, up from $615 in 2026. This is a finalized amount under the Contract Year 2027 Part D final rule. Individual plans may set a lower deductible or structure their benefit differently.
Has the 2027 Part A hospital deductible been announced?
Not yet. The official 2027 Part A inpatient hospital deductible is expected around November 2026. For reference, the 2026 deductible is $1,736 per benefit period, up from $1,676 in 2025. A similar increase would put the 2027 figure near $1,780 to $1,810, but that is an estimate.
Why are Medicare costs going up in 2027?
The main drivers are rising healthcare utilization, higher provider payments and medical prices, demographic shifts as more people enroll, and inflation indexing of the Part D deductible and out-of-pocket cap. Part B premiums are set to cover about 25% of projected program costs, so when spending rises, premiums follow.
Will higher earners pay more for Medicare in 2027?
Yes. Beneficiaries with income above the IRMAA thresholds pay a surcharge on both Part B and Part D. Projected 2027 thresholds begin around $112,000 for single filers and $224,000 for joint filers, based on 2025 income. Official brackets are released in November 2026.
When are official 2027 Medicare costs announced?
CMS typically announces official Part A and Part B premiums and deductibles in mid-November of the prior year, so expect confirmed 2027 figures around November 2026. Part D standard benefit parameters for 2027 are already finalized.
