Mounjaro cash price by dose at major pharmacies (Q1 2026)

Mounjaro is a once-weekly tirzepatide injection sold in 6 dose strengths: 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, and 15 mg. Each pen contains one weekly dose, so a 1-month supply is 4 pens.

Pharmacy	1 month supply (any dose) cash price
Walmart	$1,025 to $1,135
CVS	$1,055 to $1,175
Costco (member)	$935 to $1,015
Sam's Club (member)	$960 to $1,040
Walgreens	$1,050 to $1,160
Rite Aid	$1,060 to $1,170
GoodRx Gold price	$890 to $1,020

Several things worth knowing about Mounjaro's cash pricing:

• All 6 dose strengths cost roughly the same. Eli Lilly prices the higher-dose pens almost identically to the starter dose.
• Costco is consistently the cheapest retail cash price. Membership ($60/year) usually pays for itself in a single fill.
• GoodRx coupons stack with cash payments but don't combine with insurance.
• Sam's Club Plus members occasionally get an extra 10% off select prescriptions.

The cash price for Mounjaro has been relatively stable since 2024. Eli Lilly raised the list price modestly in early 2025 (about 3-4%) and held it through 2026.

Mounjaro with insurance: real copay scenarios

What you actually pay with insurance varies more than the cash price. Five anonymized scenarios drawn from real patient data:

Scenario 1: Employer PPO with strong pharmacy benefits. Patient has Aetna through a Fortune 500 employer. Mounjaro is on Tier 2 (preferred brand). Copay $35 per fill after deductible. Deductible met by April. Monthly cost: $35 (May-December), full retail until deductible met.

Scenario 2: Marketplace silver plan. Patient has a marketplace silver plan. Mounjaro is on Tier 3 (non-preferred brand) with 30% coinsurance. Negotiated price $920. Coinsurance: $276 per fill. Plus the $4,500 deductible.

Scenario 3: High-deductible HSA-eligible plan. Patient has a $3,500 deductible. Until met, pays full negotiated rate ($1,015). After deductible met, copay drops to $50.

Scenario 4: Medicare Part D. Patient is 68, retired, on Medicare Part D. Mounjaro for T2D is covered with a $275 specialty copay. Eli Lilly savings card doesn't apply. Monthly cost: $275, sometimes higher in the coverage gap.

Scenario 5: Medicaid (state varies). Patient on a state Medicaid plan that covers Mounjaro for T2D after prior authorization. Copay $4 per fill. PA approval took 11 days.

The lesson is similar to Ozempic: "What does Mounjaro cost" depends on your insurance plan, not on the pharmacy. The variation between Walmart and CVS is small. The variation between insurance plans is huge.

The Eli Lilly Mounjaro Savings Card

The savings card is Eli Lilly's manufacturer copay assistance program for Mounjaro.

Eligibility:

• Commercial insurance that covers Mounjaro (with any copay amount)
• Mounjaro prescribed for type 2 diabetes
• U.S. resident
• Not enrolled in Medicare, Medicaid, TRICARE, VA, or any government program

What it does:

• Reduces eligible copays to as little as $25 per fill
• Maximum benefit roughly $150 per fill
• Approximately $1,800 maximum savings per year per patient
• Limited duration of use

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
• Pharmacist runs insurance first, then applies the savings card to reduce your copay

A patient with Mounjaro on Tier 3 with a $300 copay, using the savings card, pays $150 (the card knocks $150 off). A patient with Mounjaro on Tier 2 with a $40 copay, using the savings card, pays $25 (the card brings the copay down to the $25 floor).

The card doesn't apply to Medicare patients, which is the most common reason Mounjaro looks more expensive on Medicare than on commercial insurance.

Medicare and Medicaid coverage

Medicare Part D. Mounjaro is covered for type 2 diabetes management on most Medicare Part D formularies, typically as a specialty-tier drug. Specialty tier copays run $200-$500 monthly depending on the plan. Medicare patients aren't eligible for the Eli Lilly savings card. The coverage gap (donut hole) can push monthly costs higher mid-year for some patients.

Medicare does not cover Mounjaro for weight loss as of early 2026. Some patients use Mounjaro off-label for weight loss; Medicare denies these claims.

Medicaid. Coverage varies significantly by state. Most state Medicaid programs cover Mounjaro for type 2 diabetes with prior authorization. Coverage criteria typically require:

• A documented type 2 diabetes diagnosis
• A trial of at least one prior diabetes medication (often metformin)
• A specific A1C threshold (often above 7.5% or 8%)

A few state Medicaid programs cover Mounjaro for weight loss at the BMI thresholds Medicare uses for Wegovy and Zepbound. Most don't.

TRICARE and VA. Both cover tirzepatide for type 2 diabetes through their formulary processes. Specific copays follow the agency's drug benefit structure rather than commercial pricing.

The Lilly Cares Patient Assistance Program (free Mounjaro)

Eli Lilly offers a separate program for patients with limited means: 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 doesn't cover Mounjaro
• Mounjaro prescribed for type 2 diabetes

What it provides:

• Free Mounjaro for up to 12 months at a time, renewable annually
• Shipped from Eli Lilly to the patient's provider's office or designated pharmacy
• No copay, no deductible, no insurance involvement

How to apply:

• Application available on the Lilly Cares website
• Provider signs the medical necessity portion
• Approval typically takes 7-14 business days

Lilly Cares is the cheapest path for income-qualified patients without coverage, full stop. The application is paperwork-heavy on the provider side, which is why many providers don't routinely mention it. Patients who think they may qualify should ask.

Why Mounjaro is so expensive

Mounjaro's list price reflects three structural factors:

1. Patent protection. Tirzepatide is patent-protected through 2036 in the U.S. There are no generic versions. The brand-name list price is set without competition from cheaper equivalents.
2. Manufacturing complexity. Tirzepatide is a peptide, not a small molecule. Synthesis, purification, and sterile fill-finish into auto-injector pens are expensive at scale.
3. U.S. pricing structure. Brand-name drugs in the U.S. carry list prices roughly 2-3x what the same drugs cost in Canada, Germany, or Australia. The gap reflects U.S. drug pricing policy, not manufacturing cost.

Cash patients pay the most. Insurance plans negotiate net prices below the list price. Manufacturer rebates and pharmacy benefit manager negotiations further reduce the actual amount the manufacturer collects per fill. None of those discounts pass through to cash-pay patients directly.

Mounjaro cost vs Zepbound, Ozempic, and Wegovy

Mounjaro (tirzepatide for diabetes) and Zepbound (tirzepatide for weight loss) contain the same active ingredient at similar doses. List prices for the auto-injector pens are similar. The biggest cost difference between Mounjaro and Zepbound shows up in coverage (insurance is more likely to cover Mounjaro for diabetes than Zepbound for weight loss).

Drug	Active ingredient	FDA use	Cash price (1 month)
Ozempic	Semaglutide	Type 2 diabetes	$980-$1,150
Wegovy	Semaglutide 2.4 mg	Weight loss	$1,300-$1,400
Mounjaro	Tirzepatide	Type 2 diabetes	$1,025-$1,175
Zepbound	Tirzepatide	Weight loss	$1,150-$1,300
Eli Lilly Direct (Zepbound vials)	Tirzepatide	Weight loss	$549-$695

For a patient comparing Mounjaro and Zepbound directly: same drug, similar pen pricing. The Eli Lilly Direct vial program for Zepbound is significantly cheaper than pen pricing for either Mounjaro or Zepbound, but the vials are sold for Zepbound only.

For a patient comparing Mounjaro and Ozempic: similar cash pricing, similar copay landscape, different active ingredient. Tirzepatide produces more weight loss on average than semaglutide (Frias et al., NEJM 2021).

Compounded tirzepatide as a cheaper alternative

For patients without coverage and without ability to access PAP or savings cards, compounded tirzepatide is the most common cash-pay alternative.

Typical pricing (2026):

Compounded tirzepatide dose	Cash price (monthly)
2.5 mg/week	$199-$299
5 mg/week	$249-$349
7.5 mg/week	$279-$379
10 mg/week	$299-$399
12.5 mg/week	$329-$429
15 mg/week	$349-$449

Key points about compounded tirzepatide:

• Not FDA-approved. Prepared by a state-licensed compounding pharmacy in response to an individual prescription.
• Same active ingredient as Mounjaro (tirzepatide).
• Drawn from a glass vial with a U-100 insulin syringe rather than dispensed by an auto-injector.
• Not interchangeable with brand-name Mounjaro. FormBlends does not claim equivalency.

Compounded tirzepatide makes financial sense when:

• Insurance doesn't cover Mounjaro and you don't qualify for the Lilly Cares PAP.
• Your copay is over $250 monthly and unaffordable.
• You want predictable cash pricing without insurance paperwork.

Brand-name Mounjaro makes more sense when:

• Your copay with the savings card is under $50 monthly.
• You qualify for Lilly Cares (free brand-name drug).
• You strongly prefer FDA-approved medications.

How to verify your specific Mounjaro cost in 5 minutes

Step 1: Open your pharmacy's app (or call directly). Step 2: Run a test claim through your insurance. Provide your insurance details and ask for a cost estimate before filling. Step 3: Check your formulary. Search "tirzepatide" or "Mounjaro" in your insurance member portal. Note the tier and any prior authorization requirement. Step 4: Apply the savings card. If you have commercial insurance, download the Mounjaro Savings Card and ask the pharmacist to run it after insurance. Step 5: Confirm your prescription's diagnosis code. Mounjaro for type 2 diabetes is covered widely. Mounjaro for off-label weight loss is denied widely. The diagnosis code on the prescription drives most coverage decisions.

This verification, done before the first fill, prevents the most common cost surprise (a $300 copay you weren't expecting because of an off-label denial).

How much does Mounjaro cost with insurance? Typically $25 to $500 per month depending on your formulary tier, deductible status, and prior authorization. The most common range is $30 to $150 monthly for type 2 diabetes patients on commercial plans that cover Mounjaro. Off-label weight-loss prescriptions are often denied.

Does the Mounjaro savings card work without insurance? No. The card requires commercial insurance that covers Mounjaro. The card reduces a copay; it doesn't replace coverage. Without insurance, the card has nothing to subtract from.

What is the cheapest pharmacy for Mounjaro? Costco is consistently the cheapest retail cash price among major chains, typically $50-$150 less per fill than Walmart or CVS. Costco membership costs $60 a year and usually pays for itself in one fill.

Does Medicare cover Mounjaro? Medicare Part D covers Mounjaro for type 2 diabetes only. Specialty tier copays run $200-$500 monthly. Medicare does not cover Mounjaro for weight loss. Medicare patients aren't eligible for the Eli Lilly savings card.

Does Medicaid cover Mounjaro? Coverage varies by state. Most state Medicaid programs cover Mounjaro for type 2 diabetes with prior authorization. Coverage criteria typically require a T2D diagnosis, prior trial of metformin or similar, and an A1C threshold.

Why is my Mounjaro copay so high? Most likely because you haven't met your deductible, Mounjaro is on a high tier in your formulary, prior authorization hasn't been approved, or your prescription is written for off-label weight loss without coverage. The diagnosis code on your prescription drives most denials.

Can I get free Mounjaro from Eli Lilly? Income-qualified patients without prescription drug coverage can apply to the Lilly Cares Foundation Patient Assistance Program for free Mounjaro. Eligibility requires household income below 400% of the federal poverty level and a type 2 diabetes diagnosis.

Is compounded tirzepatide cheaper than Mounjaro? Yes, typically. Compounded tirzepatide runs $249-$449 monthly. Brand-name Mounjaro runs $1,025+ cash. With insurance and a low copay, brand-name Mounjaro can be cheaper than compounded tirzepatide.

Are Mounjaro and Zepbound the same drug at the same cost? Same active ingredient (tirzepatide), similar pen pricing. Coverage differs because insurance plans treat the diabetes-labeled drug (Mounjaro) and weight-loss-labeled drug (Zepbound) under separate rules. Zepbound also has Eli Lilly Direct vial pricing at $549-$695, which has no Mounjaro equivalent.

Will my Mounjaro cost go down over time? Cost can drop if your prior authorization is approved, your deductible is met mid-year, or you successfully appeal a tier placement. Cost rises if your plan reclassifies the drug or your deductible resets. Tirzepatide has no generic alternative until 2036.

Can I use GoodRx with insurance for Mounjaro? You can use either, not both at the same time. If GoodRx's price beats your insurance copay, you can pay GoodRx instead. The GoodRx payment doesn't count toward your deductible.
