Mounjaro cost without insurance is $499 a month through LillyDirect, Lilly's own pharmacy service (checked 10/18/2026). That price covers one fill of four single-dose pens. It's the same at every strength, from 2.5 mg to 15 mg.
That flat price stands out. Zepbound, which contains the same drug, costs more as the strength goes up.
If you have commercial insurance that covers Mounjaro, the savings card can bring a fill down to $25. Its monthly cap decides whether that beats $499.
How much does Mounjaro cost per month without insurance?
LillyDirect lists a self-pay price of $499 a month for each of the six pen strengths. The government's TrumpRx site shows the same $499 and sends orders to LillyDirect.
Lilly's purchase terms define one fill as a month's supply of Mounjaro which is defined as four pens per month
. Each pen holds one weekly dose. Unlike its Zepbound KwikPen and vial listings, LillyDirect's Mounjaro listing doesn't mention a needle purchase.
The LillyDirect page also says Additional taxes and fees may apply
. It doesn't say how much, so check your total at checkout.
What does a year of Mounjaro cost without insurance?
Lilly counts a month as 28 days, so a full year takes 13 fills, not 12. At $499 a fill, that's $6,487 a year before any taxes or fees.
The savings card follows the same calendar. Its $1,950 yearly cap works out to exactly 13 fills at the $150 monthly maximum.
We found no lower Mounjaro cash price on Lilly's or the government's pages (checked 10/18/2026). TrumpRx and LillyDirect both show $499.
LillyDirect sells only the single-dose pen for self-pay. The Mounjaro label (revised 08/2026) also lists vials and a KwikPen, but neither had a LillyDirect price when we checked.
What is the Mounjaro list price?
We can't give you Lilly's current figure. Lilly's price disclosure page blocked our automated check on 10/18/2026.
Here's what we could confirm:
The TrumpRx figure is $32.39 higher than Lilly's 01/2025 sheets. That suggests the list price went up since then. We couldn't find a Lilly page that says when, so we're showing both numbers with their dates.
The list price is what Lilly charges wholesalers before rebates and discounts. A cash buyer on LillyDirect pays $499, not $1,112.16. It matters more if your plan bills you a percentage of the price, or charges you the full amount until you meet a deductible.
How does the Mounjaro savings card work?
It depends on whether your commercial plan covers Mounjaro. Lilly runs two versions, and both are for the single-dose pen only.
If your plan covers Mounjaro, Lilly's card terms say you can pay as little as $25 for a 1-, 2- or 3-month fill. Savings stop at $150 for a 1-month fill, $300 for 2 months and $450 for 3 months, with a yearly cap of $1,950.
If your plan doesn't cover it, the card works more like a cash discount. You pay as low as $499, and the card covers up to $647 of the rest each month. So if a pharmacy charges more than $1,146 ($499 plus $647), you pay the difference too.
Both versions share the same limits:
- No Medicare, Medicaid, VA, TRICARE or other government drug coverage.
- An FDA-approved use, consistent with the label.
- Up to 13 fills per calendar year.
- The card ends 12/31/2026.
Lilly also bars the card if your plan runs an "alternate funding program." That's a plan that makes you apply for manufacturer help before it will cover the drug.
When is the card better than paying $499 cash?
Do the math with your own copay. Say your plan charges $120 a month: the card can bring that down to $25, which beats $499 easily.
Now say you haven't met your deductible, and your plan bills you $900 for the month. The card takes off its $150 maximum and you owe $750. The $499 cash price is $251 cheaper.
That's where the trade-off comes in. Lilly's purchase terms ask cash buyers to agree to this:
I will not count the amount I pay for Mounjaro purchased under the Program towards my insurance deductible or out-of-pocket spending requirements.
The $750 would count toward your deductible. The $499 would not.
Coverage itself may hinge on prior authorization, where your prescriber shows the plan you meet its rules before it pays (see how to appeal a denial). Plans often hand that review to a pharmacy benefit manager, a company that runs the plan's drug benefits.
Does Medicare cover Mounjaro?
Many Part D plans do, for type 2 diabetes. Lilly's savings page says that on Part D, approximately 8 out of 10 patients will pay between $0-$50
for a 28-day supply. The rest averaged about $262, based on IQVIA data from 10/2024 to 09/2025.
The savings card is closed to Medicare. The cash price isn't, but Lilly's terms say a Part D enrollee can't count it toward their Part D true out-of-pocket costs (TrOOP).
Mounjaro isn't part of the $50 Medicare GLP-1 Bridge. That program covers certain weight-loss drugs, and CMS says it's for people without type 2 diabetes.
Why does Zepbound cost less than Mounjaro?
Both contain tirzepatide, but they're separate products with different FDA-approved uses. Mounjaro is approved for type 2 diabetes. Zepbound is approved for weight management and some related conditions. Your prescription and your diagnosis decide which one you can buy.
Lilly prices them differently, too. Zepbound without insurance costs $299 to $449 a month for the KwikPen or vials, against $499 for Mounjaro (both checked 10/18/2026).
LillyDirect marks Mounjaro FSA/HSA eligible: Eligibility may vary by plan
. Lilly's card terms add that you can't claim the card's savings back from an HSA, FSA or similar account.

How we checked these prices
We read each price on Lilly's or the government's own pages on 10/18/2026. Lilly's current list-price page wouldn't load for our checker, so we say so above instead of guessing. When a price changes, we date the correction here and log it in the price change log.
