GLP‑1 cost calculator (2026): your real monthly price
Set your medication and your coverage to get your real monthly and 12-month cost. Cash programs, savings cards and Part D, each with its source and date.
How this calculator works
Prices come from the manufacturers' own published cash programs — NovoCare, LillyDirect and TrumpRx — plus CMS NADAC acquisition data as context, and program prices verified weekly against live checkouts. Each row stores the source URL and an as-of date, shown beside the number.
The math is deliberately simple: monthly cost is the pathway's published price for a 28–30 day fill; the 12-month figure is that price × 12 with no discounting. Cost per percent of body weight lost divides the 12-month total by the trial-anchored loss at month 12 — 13.7% for semaglutide 2.4 mg (STEP 1) and 19.2% for tirzepatide (SURMOUNT-1) on our plateau curve.
Known limits: savings-card terms change yearly and cap annual benefits; intro rates (Wegovy's $199 first two fills, Zepbound's dose-tiered $299–449) depend on staying inside program rules; Medicaid varies by state. Where a figure is pending re-verification it is flagged in the row note.
