Mounjaro cash price by dose and pharmacy
Mounjaro is the type 2 diabetes brand of tirzepatide, made by Eli Lilly. All dose strengths are priced similarly because Lilly sets a flat list price across its tirzepatide pen lineup. The pen carton size, not the dose, drives small price variations.

|---|---|---|---|
| 2.5 mg pen (1 month) | $1,069 to $1,150 | $1,090 to $1,180 | $980 to $1,055 |
| 5 mg pen (1 month) | $1,069 to $1,180 | $1,090 to $1,200 | $980 to $1,075 |
| 7.5 mg pen (1 month) | $1,080 to $1,200 | $1,100 to $1,210 | $990 to $1,085 |
| 10 mg pen (1 month) | $1,080 to $1,210 | $1,100 to $1,225 | $990 to $1,095 |
| 12.5 mg pen (1 month) | $1,095 to $1,225 | $1,115 to $1,240 | $1,005 to $1,110 |
| 15 mg pen (1 month) | $1,095 to $1,250 | $1,115 to $1,250 | $1,005 to $1,125 |
Lilly's published list price ("wholesale acquisition cost") for Mounjaro is $1,069.08 for any strength as of the 2024 update. Retail pharmacies mark this up to cover handling and dispensing fees. The variance you see on a given day reflects pharmacy markup, location, and any applicable discount programs.
Through Lilly Direct (Eli Lilly's direct-to-patient pharmacy), single-vial tirzepatide for compounded weight management is sold at $399 to $549 per month for Zepbound at certain doses, but Mounjaro itself (the diabetes brand) is not currently part of the direct-to-patient discount channel.
The four factors that determine your specific cost
Factor 1: Your formulary tier. Insurance plans sort medications into tiers. Mounjaro typically lands on Tier 2 (preferred brand) or Tier 3 (non-preferred brand). Some plans put it on a specialty tier with coinsurance instead of flat copay. Tier 2 copays run $30 to $75. Tier 3 runs $75 to $200. Specialty tier runs 20 to 40% coinsurance, often capped at $200 to $500 per fill.
Factor 2: Your diagnosis on the prescription. Mounjaro is FDA-approved for type 2 diabetes only. Zepbound is the FDA-approved brand for chronic weight management. If your prescription is written for diabetes, your plan's diabetes coverage applies. If it is written off-label for weight loss, most plans deny coverage entirely.
Factor 3: Your deductible status. Most plans require you to meet a deductible before insurance starts paying. With a $3,000 deductible and no prior medical spending, your first Mounjaro fill is full price. Once you have spent $3,000 cumulatively (often by mid-year for chronic medication users), the lower copay kicks in.
Factor 4: Prior authorization (PA). Most insurance plans require prior authorization for Mounjaro. Your provider submits documentation showing diabetes diagnosis, A1C history, prior medications tried, and BMI. PA approval typically takes 3 to 14 days. If denied, you pay full cash price unless your provider appeals. A 2024 GoodRx survey found 43% of new Mounjaro prescriptions required PA, and 18% of those PAs were denied on first submission.
Real insurance copay scenarios
To make the cost range concrete, here are five anonymized real-plan scenarios.
Scenario 1: Employer PPO with strong pharmacy benefits. Patient has BlueCross BlueShield through a Fortune 500 employer. Mounjaro is on Tier 2 (preferred brand). Copay is $40 per fill after a $1,000 deductible (which is met by March). Monthly cost: $40 from April through December, full retail for January through March.
Scenario 2: Marketplace silver plan. Patient has a Healthcare.gov silver plan. Mounjaro is on Tier 3 with 30% coinsurance after a $4,500 deductible. Negotiated price is $920. Coinsurance payment after deductible is met: $276 per fill. Most of the year is full retail until the deductible is reached.
Scenario 3: High-deductible HSA-eligible plan. Patient has a $3,500 deductible plan through her employer. Until deductible is met, she pays full negotiated rate ($895 at Walmart). After meeting the deductible, copay drops to $50.
Scenario 4: Medicare Part D. Patient is 70, on a Medicare Part D plan. Mounjaro for type 2 diabetes is covered with a $300 specialty copay. The Lilly savings card does not apply to Medicare patients. Monthly cost: $300, occasionally higher in the coverage gap or initial deductible phase.
Scenario 5: No insurance, no savings card. Patient is self-employed, no current coverage. Walmart cash price is $1,125 per fill. With a GoodRx coupon, $935. The Lilly savings card requires commercial insurance, so it does not help here.
The lesson: "What does Mounjaro cost" depends almost entirely on your plan, your diagnosis, and your deductible status. The retail pharmacy contributes only a small fraction of the variance.
The Eli Lilly savings card: who qualifies
The Mounjaro Savings Card is Lilly's manufacturer copay assistance program for patients with commercial insurance.
Eligibility:
- Commercial (private) insurance that covers Mounjaro
- Mounjaro prescribed for type 2 diabetes
- U.S. resident
- Not enrolled in any government program (Medicare, Medicaid, TRICARE, VA)
What it does:
- With insurance coverage that pays toward Mounjaro: copay reduced to as little as $25 per fill
- Maximum benefit cap: roughly $150 per fill (so a $300 copay drops to $150 with the card)
- Annual maximum savings cap: typically $1,800 per year
- 12-month enrollment period; renewable
Who is excluded:
- Anyone on Medicare, Medicaid, TRICARE, VA, or any government-funded plan
- Anyone whose plan does not cover Mounjaro at all (the card reduces a copay; it does not replace coverage)
- Anyone using Mounjaro off-label for weight loss
How to use it:
- Download from the Mounjaro website or get a physical card from your provider
- Present alongside your insurance card at the pharmacy
- The pharmacist runs your insurance first, then applies the savings card to reduce the copay
About 25 to 30% of Mounjaro patients qualify for and use the card based on Lilly's published statistics.
Lilly Patient Assistance Program for low-income patients
Eli Lilly offers a separate program for low-income patients: the Lilly Cares Foundation Patient Assistance Program.
Eligibility (as of 2026):
- Income below 400% of the federal poverty level (about $60,240 for an individual, $124,800 for a family of 4)
- U.S. resident or legal U.S. resident
- No prescription drug coverage, or coverage that does not cover Mounjaro
- Prescription is for type 2 diabetes management
What it provides:
- Free Mounjaro for up to 12 months at a time, renewable
- Shipped directly from Lilly to the patient's address
- No copay, no deductible, no insurance involvement
How to apply:
- Forms available on the Lilly Cares website
- Provider signs the medical-necessity portion
- Approval typically takes 5 to 14 business days
The PAP is consistently under-used relative to the number of patients who qualify. Many providers do not routinely mention it because the paperwork is provider-side and time-consuming. Patients who think they may qualify should ask their provider to submit on their behalf. The cost savings ($1,069 per month, or $12,828 per year) more than justify the provider's administrative time.
Mounjaro vs Zepbound pricing
Mounjaro and Zepbound contain the same active ingredient (tirzepatide) but are different brands for different FDA-approved indications.
| Brand | Indication | Cash price (1 month) | Lilly Direct price (single vial) |
|---|---|---|---|
| Mounjaro | Type 2 diabetes | $1,069 to $1,250 | Not available through Lilly Direct |
| Zepbound | Chronic weight management | $1,059 to $1,250 | $399 (2.5 mg vial), $549 (5 mg vial) |
The two products have nearly identical retail prices through standard pharmacy channels. The price differentiator is the Lilly Direct program, which sells single-vial Zepbound directly to patients for self-pay use at substantially lower prices. This program does not exist for Mounjaro because diabetes coverage is more often supported by insurance, while weight-loss coverage is often denied.
If your goal is weight management and you are paying cash, Zepbound (especially through Lilly Direct) is meaningfully cheaper than Mounjaro. If your goal is type 2 diabetes treatment and your insurance covers Mounjaro, the brand-name product is what your insurance will cover.
For type 2 diabetes patients without insurance, Zepbound is not an FDA-approved option (the indication is weight management, not diabetes), so the choice between Mounjaro and compounded tirzepatide becomes the practical question.
Walmart vs CVS vs Costco vs Sam's Club comparison
For a 1-month supply of Mounjaro 5 mg pen, Q1 2026 cash prices:
| Pharmacy | Cash price | Membership required |
|---|---|---|
| Walmart | $1,069 to $1,180 | No |
| CVS | $1,090 to $1,200 | No |
| Costco | $980 to $1,075 | Yes ($60/year base) |
| Sam's Club | $1,005 to $1,095 | Yes ($50/year base) |
| GoodRx Gold | Varies | Yes ($9.99/month) |
| Mark Cuban Cost Plus Drugs | Does not carry Mounjaro | N/A |
Costco consistently has the lowest cash price among major retail chains for Mounjaro. The annual savings from buying Mounjaro at Costco vs Walmart usually justify the membership fee within one fill ($60 membership; $90 to $100 savings per fill).
Walmart's advantage is convenience: most patients live closer to a Walmart, and Walmart fills the prescription while you shop. For uninsured patients, Costco is the meaningfully cheaper option if you have a membership or are willing to get one.
GoodRx coupons can lower cash price by $100 to $200 per fill but do not stack with insurance. If your insurance copay is higher than the GoodRx price, you can choose to pay GoodRx instead, but the spend will not count toward your deductible.
Mounjaro pricing under Medicare and Medicaid
Medicare Part D: Mounjaro is covered by most Medicare Part D plans for type 2 diabetes. Coverage details vary by plan. Specialty tier copays run $200 to $500 per month. Coverage gap (donut hole) and catastrophic phase rules apply. Medicare patients are not eligible for the Lilly Savings Card.
The 2026 Medicare Part D out-of-pocket cap is $2,000 per year for covered medications. Once a Medicare patient reaches this cap, all subsequent covered medication is free for the rest of the calendar year. For Mounjaro at a $300 monthly copay, this cap is reached around July.
Medicaid: Coverage varies by state. Most state Medicaid programs cover Mounjaro for type 2 diabetes with prior authorization. Coverage for off-label weight loss is rare. Check your state's Medicaid formulary.
For Medicaid patients, Mounjaro copays are typically $0 to $5 per fill once approved. The barrier is usually the prior authorization, not the copay.
Tricare and VA: Tricare covers Mounjaro for type 2 diabetes through its formulary. VA covers Mounjaro through its drug formulary, typically with no copay for veterans with service-connected diabetes. Active-duty military members typically pay no copay through Tricare.
The compounded tirzepatide alternative
For patients whose Mounjaro copay or cash price is unsustainable, compounded tirzepatide is the most common alternative.
Pricing comparison:
| Source | Monthly price |
|---|---|
| FormBlends compounded tirzepatide | $279 to $399 |
| Other major telehealth platforms | $299 to $599 |
| Local 503A compounding pharmacies | $250 to $450 |
| Lilly Direct Zepbound (single vial, weight management only) | $399 to $549 |
| Mounjaro brand cash price | $1,069 to $1,250 |
Key differences from brand-name Mounjaro:
- Compounded tirzepatide is not FDA-approved
- It is prepared by a state-licensed compounding pharmacy in response to an individual prescription
- It is drawn from a vial with a U-100 insulin syringe rather than delivered by a pre-loaded pen
- It is typically cheaper because it skips the brand-name distribution chain
When compounded makes sense:
- Your insurance does not cover Mounjaro
- Your copay is over $200 per month and you cannot afford it
- You want predictable monthly pricing without insurance paperwork
- You do not qualify for the savings card or PAP
When brand-name Mounjaro makes more sense:
- Your copay is under $50 per month with the savings card
- You need the convenience of a pre-filled pen
- You qualify for the PAP and can get Mounjaro free
- You strongly prefer FDA-approved medications
The decision is patient-specific. A licensed clinician should walk through the trade-offs with you before either option starts.

How to verify your specific Mounjaro cost in 5 minutes
Step 1: Open the Walmart Pharmacy app, CVS app, or your pharmacy's portal (or call your local pharmacy directly).
Step 2: Run a "test claim" against your insurance. This is a free service. Provide the pharmacist your insurance details. The pharmacist will run a test claim and tell you your exact copay before you fill.
Step 3: Check your insurance formulary online. Most plans publish their formulary. Search for "tirzepatide" or "Mounjaro" to see which tier it is on and whether prior authorization is required.
Step 4: Confirm savings card eligibility. If you have commercial insurance, download the Lilly Mounjaro Savings Card. Bring it to the pharmacy. Ask the pharmacist to run insurance and the savings card together.
Step 5: Get a GoodRx quote as a backup. If your insurance copay is higher than expected, the GoodRx coupon can sometimes beat it (you pay GoodRx price, but the spend does not count toward your deductible).
This 5-step verification, done before you fill, prevents the most common cost surprise (a $300 copay you were not expecting).
FAQ
How much does Mounjaro cost without insurance? Mounjaro's cash price runs $1,069 to $1,250 per month at major U.S. pharmacies in 2026. Costco is typically the cheapest among national chains at $980 to $1,125. With a GoodRx coupon, expect $900 to $1,050 across most pharmacies.
How much does Mounjaro cost with insurance? With commercial insurance covering Mounjaro for type 2 diabetes, copays run $25 to $500 per month. The most common range is $40 to $200 per fill for patients on commercial plans. The exact amount depends on your formulary tier, deductible status, and whether prior authorization is approved.
Does the Lilly savings card work for Mounjaro? Yes, with commercial insurance and a type 2 diabetes prescription. The savings card reduces eligible copays to as little as $25 per fill, with a per-fill cap around $150 in savings and an annual cap around $1,800. Medicare, Medicaid, and other government-program patients are not eligible.
Why is Mounjaro so expensive? Mounjaro's list price is $1,069 per month. The price reflects R&D costs, manufacturing complexity for a peptide injectable, branded distribution, and Lilly's pricing strategy. Insurance and savings programs reduce out-of-pocket cost for many patients but cannot change the underlying list price.
Is Mounjaro cheaper than Ozempic? The list prices are similar: Mounjaro is $1,069 per month, Ozempic is $940 to $1,150. With insurance and savings cards applied, both typically land in the same $25 to $250 monthly range for eligible patients. Side-by-side cash prices vary by pharmacy.
Is Mounjaro covered by Medicare? Yes, Medicare Part D plans cover Mounjaro for type 2 diabetes. Specialty-tier copays run $200 to $500 per month. The 2026 Part D out-of-pocket cap of $2,000 per year limits annual spending for Medicare patients on Mounjaro. The Lilly savings card does not apply to Medicare.
Is Mounjaro covered by Medicaid? Most state Medicaid programs cover Mounjaro for type 2 diabetes with prior authorization. Coverage for off-label weight loss is rare. Check your state's specific Medicaid formulary.
Can I use a GoodRx coupon for Mounjaro? Yes, if you are paying cash. GoodRx coupons typically lower Mounjaro's cash price by $100 to $200 per fill. You cannot combine GoodRx with insurance; you choose one or the other at the pharmacy counter.
Is compounded tirzepatide really cheaper than Mounjaro? For uninsured patients, yes. FormBlends compounded tirzepatide starts at $279 per month against $1,069+ cash for Mounjaro. For insured patients with low copays (under $100), brand-name Mounjaro may still be comparable or cheaper.
Why is Zepbound from Lilly Direct cheaper than Mounjaro? Zepbound (the weight-management brand) is sold through Lilly Direct in single-vial format at $399 to $549 per month for cash-paying patients. Mounjaro (the diabetes brand) is not part of the Lilly Direct program because diabetes patients more often have insurance coverage that does not exist for off-label weight-loss prescriptions.
Will my Mounjaro price change as I escalate doses? No, not meaningfully. Lilly prices all Mounjaro pens (2.5 mg through 15 mg) similarly. Cash prices vary by $50 or so across the dose range. Your copay typically does not change as you escalate.
Can I order a 90-day supply of Mounjaro? Some plans allow 90-day fills, which can reduce per-fill processing fees. Walmart, CVS, and most mail-order pharmacies support 90-day fills if your plan permits. The total cost is roughly 3x the monthly cost.
What is the cheapest way to get Mounjaro? For commercial-insurance patients with type 2 diabetes: Lilly Savings Card on top of insurance, with copays as low as $25. For uninsured low-income patients with type 2 diabetes: the Lilly Cares Patient Assistance Program (free if you qualify). For uninsured patients who do not qualify for either: compounded tirzepatide through a telehealth platform at $279 to $399 per month.
Does the Mounjaro price include the pen needles? No. Pen needles are a separate purchase. NovoFine Plus and BD Ultra-Fine pen needles run $30 to $60 per 100 needles at retail pharmacies. You need 4 needles per month for Mounjaro (one per weekly injection).
Will Mounjaro get a generic version? Not in the near term. Tirzepatide is patent-protected through 2036 in the U.S. Generic versions cannot enter the market until patents expire. Compounded tirzepatide is not a generic; it is a different regulatory category produced by state-licensed compounding pharmacies.
