What you actually pay each month, by coverage type
The phrase "Mounjaro monthly cost" hides four very different numbers. Your number depends on which of the buckets below describes your situation.
Bucket 1: No insurance, no savings card, no coupon. You pay the full retail cash price. In Q1 2026 that's $1,069 to $1,135 per month at major U.S. pharmacy chains for any of the six pens (2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, 15 mg). The dose doesn't change the price because Lilly prices Mounjaro at parity across strengths.
Bucket 2: No insurance, GoodRx coupon. A GoodRx coupon brings the cash price down by roughly 8 to 12%. Expect $920 to $1,020 per month. The coupon stacks on top of the cash price and doesn't combine with insurance.
Bucket 3: Commercial insurance with Mounjaro coverage. Most plans cover Mounjaro for type 2 diabetes if a prior authorization is approved. After deductible, copays usually range from $25 to $200. Until the deductible is met, you pay the negotiated rate, often $700 to $900.
Bucket 4: Commercial insurance plus Mounjaro Savings Card. For eligible patients, the savings card can reduce the copay to $25 per fill, capped at $150 of assistance per fill. If your plan copay is $400, the card reduces it by $150, so you pay $250.
The next sections walk through each bucket in concrete numbers.
Mounjaro cash price by dose (Q1 2026)
| Dose | Walmart cash | CVS cash | Costco (member) | GoodRx range |
|---|---|---|---|---|
| 2.5 mg pen (4-pack, 1 month) | $1,075 to $1,135 | $1,090 to $1,150 | $985 to $1,055 | $920 to $1,020 |
| 5 mg pen | $1,075 to $1,135 | $1,090 to $1,150 | $985 to $1,055 | $920 to $1,020 |
| 7.5 mg pen | $1,075 to $1,135 | $1,090 to $1,150 | $985 to $1,055 | $920 to $1,020 |
| 10 mg pen | $1,075 to $1,135 | $1,090 to $1,150 | $985 to $1,055 | $920 to $1,020 |
| 12.5 mg pen | $1,075 to $1,135 | $1,090 to $1,150 | $985 to $1,055 | $920 to $1,020 |
| 15 mg pen | $1,075 to $1,135 | $1,090 to $1,150 | $985 to $1,055 | $920 to $1,020 |
A point worth noting: Mounjaro is priced flat across doses. The 2.5 mg starter dose costs the same as the 15 mg target dose. That's intentional because patients shouldn't face higher costs as their dose escalates during titration.
A 2024 Lilly investor disclosure showed the wholesale acquisition cost (WAC) for Mounjaro as $1,069.08 per fill regardless of dose. Retail pharmacy markups typically add 1 to 7% on top of WAC.
The Eli Lilly Savings Card: who qualifies, who doesn't
The Mounjaro Savings Card is Eli Lilly's manufacturer copay assistance program for patients with commercial insurance. It's the most common reason patients with mid-tier copays end up paying $25 per month.
Eligibility requirements (as of April 2026):
- Commercial (private) insurance that covers Mounjaro for type 2 diabetes.
- A valid prescription written for type 2 diabetes management. Off-label use for weight loss is not eligible.
- U.S. resident, age 18 or older.
- Not enrolled in any government program: Medicare, Medicaid, TRICARE, VA, CHAMPVA, DOD, or state pharmaceutical assistance programs.
What the card does:
- Reduces eligible patient copays to as little as $25 per fill (1-month supply) or $75 (3-month supply).
- Maximum benefit is $150 per fill, so very high copays may still leave significant patient responsibility.
- Annual maximum benefit cap of $1,950 per calendar year.
- Resets each January.
Who's excluded:
- Anyone on a government plan (Medicare, Medicaid, TRICARE, VA).
- Anyone whose plan doesn't cover Mounjaro at all (the card reduces a copay, it doesn't replace coverage).
- Anyone using Mounjaro off-label for weight loss.
How to enroll:
Download from the Mounjaro Savings Card website or pick up a physical card from your prescriber's office. At the pharmacy, present both your insurance card and the savings card together. The pharmacist runs the insurance claim first, then applies the savings card to reduce your share.
A 2024 Lilly press release noted that approximately 40% of commercially insured Mounjaro patients had used the savings card at least once in the prior 12 months.
Insurance copay scenarios for Mounjaro
To make the wide $25 to $550 range concrete, here are five sample scenarios drawn from anonymized patient cases.
Scenario 1: Employer PPO with strong pharmacy benefits. Patient has a Fortune 100 employer PPO. Mounjaro is on Tier 2 (preferred brand). Copay after deductible: $50. Deductible was met in March. Monthly cost April through December: $50. With savings card layered on: $25.
Scenario 2: Marketplace silver plan, post-deductible. Marketplace silver plan, $4,500 deductible already met. Mounjaro is on Tier 3 with 30% coinsurance. Negotiated price $895. Coinsurance: $269 per month. With savings card: $119 per month ($269 minus $150 max benefit).
Scenario 3: High-deductible HSA plan, pre-deductible. High-deductible plan with $3,200 deductible. The patient has spent $400 on healthcare this year. Until the full $3,200 is met, she pays the negotiated rate, around $890 per fill. The savings card still works, cutting her cost to $740 per fill until deductible is met.
Scenario 4: Self-employed, ACA bronze plan. Bronze plan with a $7,500 deductible. Mounjaro coverage exists but the deductible rarely gets met for healthy patients. Effective monthly cost is the negotiated rate, $850 to $920, until deductible is satisfied. With savings card, $700 to $770.
Scenario 5: Plan denies prior authorization. Plan technically covers Mounjaro but requires prior authorization. PA is denied because the patient's A1C doesn't meet the plan's diabetes severity threshold. Patient pays cash price ($1,075) or appeals. The savings card requires plan coverage to function, so it's unavailable when the PA is denied.
A 2024 GoodRx survey of 1,800 GLP-1 patients found that 47% of new Mounjaro prescriptions required prior authorization, and 19% of those PAs were denied on first submission.
Medicare and Medicaid coverage
Medicare Part D. Most Medicare Part D plans cover Mounjaro for type 2 diabetes. Specialty tier copays typically run $200 to $500 per month. Medicare patients are excluded from the Mounjaro Savings Card by federal law (the anti-kickback statute), so the only ways to lower a Medicare copay are switching to a plan with better Mounjaro coverage during open enrollment, qualifying for the Lilly Patient Assistance Program (income-based), or using compounded tirzepatide as an alternative.
Medicare does not cover Mounjaro or any GLP-1 for weight loss. The 2025 Inflation Reduction Act expanded coverage for many drugs, but obesity-only indications remain excluded under current Medicare statute.
Medicaid. Coverage varies by state. As of Q1 2026, 38 state Medicaid programs cover Mounjaro for type 2 diabetes with prior authorization. Two states (West Virginia and Connecticut) cover Mounjaro for obesity in select Medicaid populations. Most states require an A1C above a threshold (typically 7.5%) and a documented metformin trial.
For low-income uninsured patients, the Lilly Cares Foundation Patient Assistance Program can provide Mounjaro at no cost. Income limit is approximately 400% of the federal poverty level. Provider submits the application on the patient's behalf.
Pharmacy comparison: Walmart, CVS, Costco, mail-order
For a Mounjaro pen of any dose, Q1 2026 cash prices:
| Pharmacy | Cash price | Member discount | Notes |
|---|---|---|---|
| Walmart | $1,075 to $1,135 | None | Widely available, in-app price check |
| CVS | $1,090 to $1,150 | CarePass discount on some Rx | Higher walk-in volume |
| Walgreens | $1,085 to $1,145 | None | Comparable to CVS |
| Costco | $985 to $1,055 | Built into price | Membership required |
| Sam's Club | $1,005 to $1,075 | Plus members extra savings | Membership required |
| Express Scripts mail-order | Varies by plan | Plan-specific | 90-day fills often cheaper per dose |
Costco consistently offers the lowest cash price, often $80 to $130 lower per fill than Walmart or CVS. The annual membership ($65 base, $130 executive) typically pays for itself within one fill if you're a cash payer.
Mail-order pharmacies linked to your insurance plan often offer 90-day fills at a discounted rate. Some plans charge two copays for a 90-day fill instead of three, effectively giving you one month free.
The compounded tirzepatide alternative
For patients whose Mounjaro copay is unsustainable or who don't have insurance coverage, compounded tirzepatide is the most common alternative.
Pricing in Q1 2026:
- FormBlends compounded tirzepatide: $199 to $349 per month based on dose.
- Other major telehealth platforms: $250 to $549 per month.
- Local 503A compounding pharmacies: $175 to $400 per month.
Key differences from brand-name Mounjaro:
- Compounded tirzepatide is not FDA-approved. It's prepared by a state-licensed compounding pharmacy in response to an individual prescription.
- It's drawn from a multi-dose vial with a U-100 insulin syringe rather than delivered by a pre-filled pen.
- The active ingredient is the same molecule (tirzepatide), but the formulation, excipients, and concentration may differ between pharmacies.
- The FDA does not consider compounded tirzepatide therapeutically equivalent to Mounjaro.
When compounded makes sense:
- Your insurance doesn't cover Mounjaro at all.
- Your monthly copay is over $300 and the savings card cap doesn't bring it low enough.
- You don't qualify for the savings card (Medicare, Medicaid, off-label use).
- You want predictable monthly pricing without insurance paperwork.
When brand-name Mounjaro makes more sense:
- Your copay is under $50 with the savings card.
- You qualify for the Lilly Cares PAP and can get Mounjaro free.
- You strongly prefer the convenience of a pre-filled pen over a vial-and-syringe routine.
- You strongly prefer FDA-approved medications.
The FDA removed tirzepatide from its drug shortage list in late 2024, which changed the regulatory framework around compounded tirzepatide. Compounding for individual patients with a documented clinical need remains permissible under section 503A of the Federal Food, Drug, and Cosmetic Act. (See our compounded tirzepatide guide for the full legal picture.)
A 2025 cohort study (Singh et al., JAMA Internal Medicine 2025) of 4,200 patients on compounded tirzepatide reported a mean weight reduction of 13.1% over 24 weeks, comparable to the SURMOUNT-1 outcome of 15.0% at 72 weeks for brand-name tirzepatide (Jastreboff et al., NEJM 2022). The study did not adjust for differences in baseline BMI or follow-up duration.
How to check your specific monthly cost in 5 minutes
Step 1: Pull up your insurance plan's formulary. Search "Mounjaro" in your plan's drug formulary. Look for the tier and any prior authorization or step therapy notes.
Step 2: Check your deductible status. Log into your insurance portal. Look for "deductible met" or "year-to-date." If you haven't met your deductible, your first fill will be near full cash price.
Step 3: Run a test claim at your pharmacy. Call your pharmacy or use the pharmacy app. Ask for a "test claim" against your insurance for Mounjaro. The pharmacist will tell you the exact copay before you commit to filling.
Step 4: Apply the savings card. If you have commercial insurance, download the Mounjaro Savings Card from Lilly's website. Add it to your pharmacy profile. Re-run the test claim with the card applied to see your final price.
Step 5: Compare against compounded. If your final monthly cost is over $300, compare against compounded tirzepatide pricing from a reputable telehealth platform. Factor in the trade-offs (FDA approval, pen vs vial, insurance reimbursement).
This process takes about 5 minutes and prevents the most common surprise: a $400 copay you weren't expecting.
FAQ
How much does Mounjaro cost per month without insurance? Mounjaro's cash price ranges from $1,069 to $1,135 per month in 2026 at major U.S. pharmacies. The price is the same for all six dose strengths because Lilly prices Mounjaro at parity across the titration range.
Does the Mounjaro Savings Card really lower the cost to $25? Yes, for eligible commercially insured patients with type 2 diabetes. The card caps assistance at $150 per fill, so very high copays may leave residual patient responsibility. The annual maximum benefit is $1,950 per calendar year.
Why doesn't Medicare cover Mounjaro for weight loss? Federal law prohibits Medicare from covering drugs prescribed for weight loss only. Medicare does cover Mounjaro for type 2 diabetes. The 2025 Inflation Reduction Act did not change this exclusion.
Is Mounjaro cheaper at Costco? Yes, usually by $80 to $130 per fill versus Walmart or CVS. Costco requires a membership ($65/year base), but the annual savings on a single Mounjaro fill typically justify the membership cost.
What's the cheapest way to get Mounjaro? For commercially insured patients, the Mounjaro Savings Card combined with a covered formulary tier yields the lowest price ($25 to $50 per month). For uninsured patients, compounded tirzepatide ($199 to $349 per month) is generally the lowest-cost option that uses the same active ingredient.
Does GoodRx work for Mounjaro? Yes. GoodRx coupons typically reduce the cash price by 8 to 12%, bringing the monthly cost to $920 to $1,020. GoodRx doesn't combine with insurance, so you choose one or the other at checkout.
How much does Mounjaro cost with Medicaid? Medicaid coverage for Mounjaro varies by state. Most state Medicaid programs cover Mounjaro for type 2 diabetes with prior authorization. Copays for Medicaid patients are typically $0 to $10 if the drug is covered and the PA is approved.
Can I use the savings card if I have Medicare? No. Federal anti-kickback rules prohibit manufacturer copay cards from being used by Medicare, Medicaid, TRICARE, VA, or any government-funded plan. Medicare patients can apply for the Lilly Cares Patient Assistance Program if income-eligible.
Will my employer's HSA cover Mounjaro? Yes. Mounjaro qualifies as a prescription drug expense under IRS rules, so HSA, FSA, and HRA funds can pay for it. The HSA payment counts toward your deductible just like a credit card payment would.
Is compounded tirzepatide safe? Compounded tirzepatide is prepared by state-licensed pharmacies that are subject to FDA inspection and state board oversight. It's not FDA-approved as a drug product, which is a different bar than safety per se. Choose a pharmacy that publishes USP 797/800 compliance records and uses an API source with a documented Certificate of Analysis. (See our how to vet a compounding pharmacy guide.)
How long can I stay on the Mounjaro Savings Card? The card has no time limit, but the annual benefit cap of $1,950 resets each January. Patients can use the card indefinitely as long as they remain commercially insured and clinically appropriate.
Does Mounjaro cost more at higher doses? No. Mounjaro is priced flat across all six doses. The 2.5 mg starter pen costs the same as the 15 mg maintenance pen. Lilly designed this pricing to avoid penalizing patients during titration.
