Mounjaro Cost on GoodRx: Price Breakdown for 2026

With a GoodRx coupon, Mounjaro costs roughly $990 to $1,100 a month in 2026, depending on the pharmacy. That’s only modestly below Eli Lilly’s 2026 list price of $1,112.16 for a 28-day supply, because Lilly’s contracts limit how deeply third-party discount cards can cut the price of brand-name GLP-1s. So while GoodRx is worth a look, it rarely delivers dramatic savings on Mounjaro. If you have type 2 diabetes and commercial insurance, a manufacturer savings card usually beats any coupon. Here’s how the numbers work and where to find lower prices.

What Mounjaro costs with GoodRx

GoodRx and similar cards like SingleCare negotiate cash discounts you can use without insurance. On Mounjaro, those discounts are real but small.

Lilly raised Mounjaro’s list price to $1,112.16 at the start of 2026, up from $1,069.08 the year before, and the price is identical across all dose strengths. Average retail can run higher once pharmacy and wholesaler markups stack on, which is why a coupon that lands near $990 to $1,000 still beats paying sticker.

Why GoodRx savings on Mounjaro stay small

Discount cards work best on generics and older brands. Mounjaro is a patent-protected, first-in-class drug with no generic, and Lilly’s pharmacy contracts cap how much third-party cards can discount it. Practically, that means a GoodRx price at Costco or Walgreens often lands within a few dollars of the pharmacy’s standard cash price. It’s still worth comparing coupons across pharmacies before each fill, but don’t expect a coupon to cut the price in half the way it might for a common generic.

The Mounjaro Savings Card

If you have commercial insurance and a type 2 diabetes diagnosis, the Lilly savings card is almost always the better deal. With a plan that covers Mounjaro, eligible patients pay as little as $25 for a one to three month fill, up to $1,950 a year across 13 fills. If your commercial plan doesn’t cover it, the card still caps your cost at about $499 a month. Medicare, Medicaid, and other government beneficiaries aren’t eligible.

What if you’re taking Mounjaro for weight loss?

Mounjaro is FDA-approved for type 2 diabetes, not weight loss, so the savings card requires a diabetes diagnosis. If you’re using tirzepatide for weight management without diabetes, the card won’t apply, and insurance almost certainly won’t cover Mounjaro for that purpose. The same molecule is sold as Zepbound for weight loss, which has its own lower-cost LillyDirect vials ($299 to $449 a month). Cash-pay telehealth is another route to physician-prescribed tirzepatide.

Medicare and Mounjaro

Medicare Part D generally covers Mounjaro for type 2 diabetes, and under the Inflation Reduction Act’s $2,000 annual out-of-pocket cap, many Part D enrollees pay between $0 and $50 a month. You can’t combine the savings card with Medicare, and Part D won’t cover Mounjaro for weight loss.

Lower-cost tirzepatide options

In the SURPASS-2 trial, tirzepatide outperformed semaglutide on both blood sugar and weight in adults with type 2 diabetes, which helps explain its popularity and its price. Consider a scenario where someone without diabetes is paying full cash for Mounjaro because a friend recommended it. Switching the conversation to Zepbound or a cash-pay tirzepatide program could cut their monthly cost substantially. TrimRx offers physician-prescribed tirzepatide through a cash-pay telehealth model, priced from $179 to $1,579 a month depending on the medication and your situation.
