GLP-1 cost per pound lost calculator

The short answer

The medication with the lower monthly price is often the more expensive one per pound lost, because the two drugs do not take the same weight off. Take a 200lb starting weight and each drug's own trial: Wegovy lists at $1,350 a month and averaged 14.9% over 16 months — about 30 lb for $21,600, or $725 a pound. Zepbound lists lower, at $1,086 a month, and averaged 22.5% over 17 months — about 45 lb for $18,462, or $410 a pound. Same list-price ballpark, 1.8× the cost per pound. Compounded tirzepatide comes out near $132 a pound on the same arithmetic, with the regulatory trade-off that it is not an FDA-approved finished product. Trial averages, not a promise about you — the calculator below runs it on your own weight.
