Without insurance, Mounjaro at Costco costs roughly $1,040 to $1,100 a month for a 28-day supply of four pens in 2026, among the lower cash prices at major pharmacies. Costco and Sam’s Club tend to run a bit below CVS, Walgreens, and Rite Aid, with Walmart in between. Lilly’s 2026 list price is $1,112.16, flat across all doses, so the warehouse discount is real but modest. If you have type 2 diabetes and commercial coverage, a savings card can bring you to as low as $25. Here’s the full picture, and where tirzepatide gets cheaper.<\/p>\n

What Mounjaro costs at Costco<\/h3>\n

Costco’s pharmacy operates near break-even as a way to keep members happy, which translates into consistently low cash prices. Mounjaro’s price is the same at every dose.<\/p>\n

How Costco compares to other pharmacies<\/h3>\n

Across major retailers in 2026, the cash-price ranking for Mounjaro roughly runs from the warehouse clubs at the low end up through the chain drugstores. Costco and Sam’s Club usually sit lowest, often within $10 to $30 of each other. Walmart lands slightly higher, with CVS, Walgreens, and Rite Aid higher still. Independent pharmacies vary widely. If you’re paying cash and have a warehouse membership, that’s typically your best brick-and-mortar price.<\/p>\n

GoodRx at Costco<\/h3>\n

Costco accepts GoodRx coupons, but for Mounjaro the coupon price is usually about the same as Costco’s standard cash price. Lilly’s contracts limit how much third-party discount cards can cut brand-name GLP-1 pricing, so don’t count on a coupon to drop the cost meaningfully below the warehouse rate. It’s still worth a quick price check at the counter.<\/p>\n

Membership programs, HSA, and FSA<\/h3>\n

Some Costco members without insurance can use the Costco Member Prescription Program for additional savings on certain drugs. HSA and FSA funds cover Mounjaro at Costco when you have a qualifying diagnosis, and the pharmacy’s receipts are formatted for reimbursement. Using pre-tax dollars effectively lowers the cost by your tax bracket.<\/p>\n

A note on LillyDirect<\/h3>\n

Lilly’s lower-priced self-pay vials ($299 to $449 a month) are for Zepbound, not Mounjaro. Mounjaro isn’t yet available through LillyDirect’s self-pay program, though Lilly announced in late 2025 that it plans to add it at a discount; the pricing hasn’t gone live for patients. For now, if you want tirzepatide for weight loss and are paying cash, Zepbound vials or a cash-pay telehealth program are usually the more affordable tirzepatide routes.<\/p>\n

Lower-cost tirzepatide options<\/h3>\n

Mounjaro’s track record in type 2 diabetes is strong. In the SURPASS-1 trial, tirzepatide as a standalone therapy produced significant reductions in blood sugar, establishing the foundation for its later use. But the retail price is steep for anyone paying out of pocket. Consider a scenario where someone with diabetes has a high-deductible plan and faces the full cash price until they hit their deductible. Comparing Costco’s price against a savings card, and asking their provider about timing fills, could save real money. TrimRx offers physician-prescribed tirzepatide through a cash-pay telehealth program, priced from $179 to $1,579 a month depending on the medication and your situation.<\/p>\n
