The Verdict · Calculators
Make sense of the numbers behind your treatment.
Compare treatment costs, check a billing cycle, or understand a change in weight. Our free tools explain their assumptions and show the calculation. Provider prices come from the records behind our rankings; dose conversions and schedules require the prescription and product label that apply to you.
The tools
407 of the 548 providers we review publish a price for at least one molecule; 154 publish no semaglutide figure and 177 publish no tirzepatide figure. The calculators use the ones that do and name the ones that do not.

GLP-1 dose calculator
mg → units on an insulin syringe
Enter your weekly dose and the concentration printed on your vial; get the units to draw on a U-100 syringe, the whole label escalation ladder converted at that strength, and what a month of the medicine costs at the 407 providers publishing a price.

GLP-1 true cost calculator
what you pay at month 12, not what the sticker says
Advertised rates hide two things: intro rates that step up, and terms you cannot leave. This prices every provider over your own horizon with both applied, and names every row whose bill exceeds its headline.

GLP-1 titration schedule planner
how long the climb takes, and what it costs
The Wegovy and Zepbound escalation schedules week by week, mapped onto billing months — plus the cost of every month spent getting to a maintenance dose.

Where the numbers come from
Provider prices and product labels inform the treatment tools. The billing and weight-change tools show their arithmetic and assumptions.
Prices — our ranking
Compare published medication prices alongside the conditions attached to them: introductory rates, dose tiers, prepaid terms and separate care fees. The cost tools use the 548 provider records behind our rankings and identify offers that cannot be modeled reliably. Confirm the complete quote before paying.
Doses — the FDA labels
The schedule tools cite the Wegovy (semaglutide) injection and Zepbound (tirzepatide) injection prescribing information. Check the exact product and your prescription before using a schedule or converting units. Compounded semaglutide and tirzepatide are not FDA-approved and have no label of their own; prescribers commonly titrate them against the brand schedule, and yours may not. None of this is a dosing instruction.
Then read the rankings
A calculator answers a number. The rankings answer who to buy from.
