Tirzepatide Cost Calculator: Compounded vs Brand

Use this calculator to compare the monthly and annual cost of compounded tirzepatide from BiltRx and Arc-1 against brand-name Zepbound and Mounjaro. Enter your dose tier and the calculator estimates total spend including consultation and shipping where published. All prices are from provider product pages verified in October 2026.

Calculate Your Monthly Tirzepatide Cost

How the Calculator Works

The calculator uses published pricing from BiltRx, Arc-1 and Eli Lilly's list prices for brand-name products. Select a dose tier and the tool projects monthly and annual costs for each option side by side.

Compounded Tirzepatide Inputs

BiltRx charges $129 per month at any dose. Consultation and shipping are extra but not published, so the calculator shows them as separate line items you can estimate. Arc-1 prices include everything: $199.99 (2.5 mg), $249.99 (5 mg), $399.99 (7.5 mg). No additional fees to add.

Brand-Name Tirzepatide Inputs

Zepbound and Mounjaro both list at $1,499 per month without insurance. The calculator shows this as the baseline. If you have insurance coverage, your out-of-pocket cost could be significantly lower, but that depends on your specific plan, copay tier and whether prior authorization is approved.

Additional Fees

BiltRx consultation and shipping fees are not published. The calculator lets you add estimated amounts. Lab work, if your provider orders it, is billed separately by the lab and is not included in any provider's pricing. Follow-up telehealth visits are typically included in both platforms' subscription models.

Price Reference Table

Annual Cost Projections

Over 12 months, the savings from compounded tirzepatide versus brand-name are substantial. Most patients escalate from a starting dose to a maintenance dose during the first year, which affects Arc-1's annual total more than BiltRx's (since BiltRx's price is flat).

A patient starting at 2.5 mg on BiltRx and staying there for 12 months spends $1,548 on medication alone. The same patient on Arc-1 spends $2,399.88 all-in. At the 7.5 mg dose, BiltRx medication cost remains $1,548 while Arc-1 reaches $4,799.88. Either compounded option is 73-91% less than brand-name at list price.

What the Numbers Do Not Include

Insurance Copays and Deductibles

If you have insurance that covers Zepbound or Mounjaro, your actual out-of-pocket cost may be much lower than the $1,499 list price. Copays range from $25 to hundreds of dollars depending on your plan. The calculator shows list price; adjust for your insurance coverage if applicable.

Dose Escalation Over Time

Most patients do not stay on the starting dose. Tirzepatide treatment typically involves dose escalation over the first several months. On Arc-1, moving from 2.5 mg to 5 mg to 7.5 mg increases monthly cost at each step. On BiltRx, the monthly cost stays at $129 regardless of dose changes. Factor dose escalation into your annual projections.

Lab Work and Follow-Up Visits

Your provider may order blood work (metabolic panel, A1C, lipid panel) before starting treatment and periodically during treatment. Lab costs are billed by the lab, not the telehealth platform. Follow-up telehealth visits are generally included in both providers' subscription models, but in-person lab work is an additional expense.
