What Is the Medicare Part D Out-of-Pocket Maximum? 2026 and 2027 Caps Explained

Short answer: The Medicare Part D out-of-pocket maximum is $2,100 in 2026. Once your out-of-pocket spending on covered Part D drugs reaches that amount, you automatically get catastrophic coverage and pay nothing more for covered Part D drugs for the rest of the calendar year. Medicare.gov lists a $2,400 cap for 2027. Your deductible and certain payments made on your behalf, such as through Extra Help, count toward the limit.

For retirees, that cap turns prescription drugs from an open-ended expense into one you can put a ceiling on in your budget. This guide explains how the limit works, what changes in 2027 and the programs that can spread out or lower what you pay.

What Is Medicare Part D?

Medicare Part D is Medicare's prescription drug coverage. You get it through a Medicare drug plan, and what you pay depends on the plan you choose. Medicare.gov says premiums, deductibles, copayments and coinsurance vary by plan, and that your premium may be higher depending on your income.

Our guide to IRMAA after a home sale explains how that income-based amount works. For what the rest of Medicare covers, see what Medicare covers.

What Is the Part D Out-of-Pocket Maximum for 2026?

The 2026 Part D out-of-pocket maximum is $2,100. Medicare.gov describes it as the point where "catastrophic coverage" begins. After you reach it, you won't have to pay out-of-pocket for covered Part D drugs for the rest of the calendar year.

What Changes in 2027?

Two figures rise for 2027:

Part D limit	2026	2027
Out-of-pocket maximum for covered drugs	$2,100	$2,400
Highest deductible a plan may charge	$615	$700

Separately, CMS announced on July 28, 2026, that the Part D base beneficiary premium will be $41.33 for 2027. CMS describes it as the starting point for calculating a plan-specific basic Part D premium.

If you're building a retirement budget, the 2027 increase means the most you could pay for covered drugs goes up by $300, before premiums.

What Counts Toward the Out-of-Pocket Maximum?

Medicare.gov says the limit includes three things:

1. Your deductible. What you pay before your plan starts sharing costs.
2. Your out-of-pocket spending on covered Part D drugs, such as coinsurance.
3. Certain payments made on your behalf, for example through the Extra Help program.

Medicare.gov lists premiums as their own cost that varies by plan, so plan for your monthly premium as a separate line in your budget.

How Do the Three Part D Coverage Stages Work?

Medicare.gov describes three stages. Here's how a year moves through them in 2026:

1. Deductible stage. If your plan has a deductible, you pay the full cost of your drugs until you meet it. No plan may have a deductible above $615 in 2026, and some plans have no deductible.
2. Initial coverage stage. After the deductible, you pay 25% of the cost as coinsurance for generic and brand-name drugs. This lasts until your out-of-pocket spending reaches $2,100.
3. Catastrophic coverage. You pay nothing out-of-pocket for covered Part D drugs for the rest of the calendar year.

What Is the Medicare Prescription Payment Plan?

The Medicare Prescription Payment Plan lets you pay your Part D drug costs in monthly amounts instead of all at once at the pharmacy. It changes when you pay, not how much you pay. Medicare.gov says it might help you manage monthly expenses, but it doesn't save you money or lower your drug costs. You're still responsible for the costs.

Medicare.gov's guidance on who it fits:

• You're most likely to benefit if you have high drug costs earlier in the calendar year.
• It may not be the best choice if you sign up late in the calendar year (after September).
• To start, visit your health or drug plan's website or call your plan.

For a retiree on a fixed income, this can matter. Without it, someone who reaches the $2,100 cap in the first months of the year pays most of that amount at the pharmacy counter early on. Spreading it out can make those months easier to manage, even though the yearly total is the same.

Who Can Get Extra Help With Part D Costs?

Medicare.gov describes Extra Help as a Medicare program that helps pay your drug costs. Social Security says it's for people with limited income and resources. Social Security estimates it's worth about $5,700 per year. It can help pay monthly premiums, annual deductibles and prescription copayments.

Medicare.gov says you automatically qualify if you have Medicaid, a Medicare Savings Program or Supplemental Security Income (SSI). If you don't qualify automatically, you can apply. Social Security's August 2026 Extra Help publication lists these limits:

Limit	Single person	Married couple living together
Resources	$18,090	$36,100
Annual income	$23,940	$32,460

Resources include things like bank accounts, stocks, IRAs and real estate other than your home. Your primary residence and your vehicles don't count.

You can apply online at ssa.gov/medicare/part-d-extra-help. People who get Extra Help also don't pay the Part D late enrollment penalty.

Medicare.gov lists other programs that may lower drug costs, including Medicaid, the Limited Income Newly Eligible Transition (LI NET) program, State Pharmaceutical Assistance Programs and drug manufacturer assistance programs.

What Is the Part D Late Enrollment Penalty?

If you go 63 or more days in a row without Part D or other creditable drug coverage after your enrollment period ends, you may owe a late enrollment penalty. Medicare.gov says it's figured as 1% of the national base beneficiary premium ($38.99 in 2026) times the number of full months you went without coverage, and it's added to your premium.

That makes the timing of your Medicare sign-up part of retirement planning. Our guide to who qualifies for Medicare and when to sign up covers the enrollment windows.

How Should You Plan for Drug Costs in Retirement?

The cap gives you a worst-case number for covered drugs. A few steps help turn it into a plan:

1. Use the cap as your ceiling. For 2026, $2,100 is the most you'd pay out-of-pocket for covered Part D drugs. By our math, that's $175 a month spread over 12 months. Add your plan's premium on top.
2. Update the figure for 2027. The cap rises to $2,400, which works out to $200 a month by our math.
3. Check your plan's deductible. It counts toward the cap, and until you meet it you pay the full cost of your drugs.
4. Decide whether monthly payments help. If your costs come early in the year, the Medicare Prescription Payment Plan can spread them out.
5. See whether you qualify for Extra Help if your income and resources are limited.
6. Build drug costs into your savings target. Our retirement savings calculator can help you see how ongoing health costs fit with the rest of your plan.

The Bottom Line

The Medicare Part D out-of-pocket maximum puts a yearly ceiling on what you pay for covered drugs: $2,100 in 2026 and $2,400 in 2027. Your deductible and certain payments made on your behalf count toward it. The Medicare Prescription Payment Plan can spread those costs over the year without lowering them, and Extra Help can reduce them for people with limited income and resources. For a retirement budget, the cap plus your premium gives you a clear number to plan around.
