What the calculator does
It takes the five numbers that determine what a GLP-1 plan costs — starting price, maintenance-dose price, membership, shipping, and any one-time consultation fee — and computes the true monthly cost at maintenance dose and the 12-month total, using the same arithmetic as the site's methodology. Choosing a provider from the list prefills the fields from our database, with the verification status shown, so you can check our figures or adjust them if a provider's page has changed.
How to use it against a provider's page
Open the provider's pricing page next to this tool. Enter the price shown at the starting dose. Find the price at the highest dose tier (for tirzepatide, 12.5 or 15 mg; for semaglutide, 2.4 mg) — if the provider does not publish one, that is worth knowing. Add the membership fee if it is billed separately, shipping if it is not included, and any consultation fee. The 12-month total that results is the number to compare across providers, and it is the number our rankings use.
Reading the result
The advertised price is what the provider wants you to compare. The true monthly cost at maintenance is what you will pay from about month four. The 12-month total is what a year costs. If the gap between the first and third numbers is large, the provider's price structure is designed to look cheaper than it is. If the gap is zero, the provider is flat-rate and all-inclusive.
