Mounjaro cost without insurance is $1,112.16 per 28-day fill (four pens) at list price, according to Lilly’s pricing page as of January 1, 2026.[1] Most people paying cash do better through LillyDirect, Lilly’s own pharmacy, where self-pay Mounjaro starts at $499 a month for every dose.[2]
Prices and program terms checked October 2026. They change often; confirm with the manufacturer or your plan.
Mounjaro is tirzepatide, the same medicine sold as Zepbound. For how the drug works, see our tirzepatide profile.

Why most people don’t pay the list price
The list price, also called the wholesale acquisition cost, is what Lilly charges wholesalers. Lilly notes that the price at the pharmacy can differ and depends on pharmacy charges, insurance and any discounts.[1] A month of Mounjaro is four single-dose pens, one per week, and every strength from 2.5 mg to 15 mg carries the same list price.[6]
If you have no insurance at all, the list price is the number a regular pharmacy will start from. That is why the LillyDirect self-pay price matters most for uninsured people.
Mounjaro self-pay through LillyDirect
In November 2025, as part of its pricing agreement with the U.S. government, Lilly said it would add Mounjaro to LillyDirect for self-pay patients at 50% to 60% off the list price.[4] As of October 2026, LillyDirect lists every Mounjaro pen strength (2.5, 5, 7.5, 10, 12.5 and 15 mg) at a self-pay price starting at $499 a month.[2]
How it works:
- Your prescriber sends the prescription to LillyDirect Pharmacy.
- A pharmacy partner contacts you to confirm details and check for savings.
- You choose home delivery or pickup at a retail pharmacy.[2]
A prescription is still required, and taxes and fees may apply.[2] Lilly also says self-pay purchases may be HSA and FSA eligible, depending on the plan.[2]
Does the Mounjaro savings card help without insurance?
No. The Mounjaro Savings Card has two tiers, and both require commercial drug insurance (insurance from an employer or bought on your own, not a government program):[3]
- Plan covers Mounjaro: pay as little as $25 for a 1-, 2- or 3-month fill. Lilly pays up to $150 a month and up to $1,950 a year.
- Plan does not cover Mounjaro: pay as low as $499 for a 1-month fill. Lilly pays up to $647 a month and up to $8,411 a year.
People on Medicare, Medicaid, TRICARE, VA or other government coverage are excluded, and the card must be used for an approved use that matches the label.[3] The card expires on December 31, 2026.[3] Our Mounjaro savings card guide covers the full terms.
Mounjaro vs Zepbound vials: same drug, different price
Without insurance, Zepbound is often the cheaper tirzepatide product. Through LillyDirect, Zepbound single-dose vials and the four-dose KwikPen cost:[5]
| Dose | Zepbound vial or KwikPen (self-pay) | Mounjaro pen (self-pay) |
|---|---|---|
| 2.5 mg | $299 | From $499 |
| 5 mg | $399 | From $499 |
| 7.5 to 15 mg | $449 if refilled within 45 days | From $499 |
If a Zepbound refill at 7.5 mg or higher is late (more than 45 days after the last delivery), the price rises to $499 for 7.5 mg and $699 for 10, 12.5 or 15 mg.[5]
The catch is the approved use. Mounjaro is approved for type 2 diabetes in adults and children 10 and older, and to lower the risk of heart attack, stroke and cardiovascular death in adults with type 2 diabetes.[6] Zepbound is approved for weight management and for moderate to severe obstructive sleep apnea in adults with obesity.[7] Your prescriber chooses the product based on your diagnosis. Lilly’s savings programs also require a prescription for an approved use.[3] See Zepbound vs Mounjaro for the differences, and our Zepbound cost without insurance guide for full Zepbound prices.
Yearly cost without insurance
Lilly defines a month as 28 days, so a full year is 13 fills.[1]
| Route | Per fill | Per year (13 fills) |
|---|---|---|
| List price | $1,112.16 | $14,458.08 |
| LillyDirect self-pay | $499 | $6,487 |
These are estimates before taxes and fees. Your actual cost depends on how many fills you need and whether prices change mid-year.
Other ways to lower the cost
- Medicare Part D: Lilly says Mounjaro is covered on many Part D plans for type 2 diabetes, and about 8 in 10 Part D patients pay $0 to $50 for a 28-day supply (based on IQVIA data from October 2024 to September 2025).[3]
- Medicaid: coverage and copays vary by state. Lilly points people to Medicaid.gov to check eligibility.[1]
- Lilly Cares: Lilly’s free-medicine program does not list Mounjaro as of October 2026.[8] It does list Trulicity, a different diabetes drug. See our Mounjaro patient assistance program guide.
- Ask about other options: if cost is the barrier, a prescriber can discuss other diabetes medicines that may be cheaper or covered, such as dulaglutide.
Before you pay cash
A few checks can save money before you commit to a full year of self-pay fills:
- Confirm you are truly uninsured for this drug. If you have any commercial insurance, even a plan that excludes Mounjaro, the savings card’s $499 tier may apply, and a plan that covers it may bring the cost down to $25.[3]
- Ask your plan about a formulary exception. If an employer plan lists Mounjaro as non-preferred, your prescriber can request an exception or prior authorization for type 2 diabetes.
- Compare the device. Mounjaro comes only as single-dose pens, and the self-pay price is the same at every strength, so moving up a dose does not change what you pay through LillyDirect.[2]
- Watch for plan changes at renewal. Employer coverage often changes on January 1, and the savings card itself expires on December 31, 2026.[3]
- Keep receipts. Cash purchases may count toward HSA or FSA spending, but they generally do not count toward an insurance deductible.
