4 calculators, each doing one conversion by itself rather than asking you to trust a seller’s math: what a “starting at” price actually totals over its term, and what the approved dose ladder costs to climb. Neither recommends a dose or a seller — each computes what the numbers you enter imply, and shows the work.
Cost Calculator
Enter a seller's own monthly figure, its plan term and any up-front fee, and see the true cost per month and the total for the term — checked against real published GLP-1 prices with their verification dates.
Open the calculator →Dose and costTitration Planner
The approved week-by-week ladder for semaglutide and tirzepatide, read off the current labels — and what climbing it costs at a seller that holds one price against one that re-prices at every step.
Open the calculator →What the trials foundExpected Weight Loss
Enter a starting weight and see the published distribution from STEP 1 and SURMOUNT-1 applied to it — not the arm mean every landing page quotes, but how many participants reached each threshold and how many did not.
Open the calculator →Is that a normal price?Price Check
Enter the monthly figure a seller quoted you and see where it lands among every published price on this site — corrected for fees and four-week terms — with the median, the range and how many are lower.
Open the calculator →Or read the boards
For questions a single conversion can’t answer — which seller, which format, whether the evidence holds up — these boards answer them with the working shown.
Every published price, lowest first
Ranked strictly on the standing month-to-month rate — never an introductory month, a first-order coupon, or a prepaid quarter divided out to look smaller. If a seller's homepage and its checkout disagreed, we used the one you would be billed on month two.
Open the board →Which format?Oral against injectable, priced separately
The comparison a calculator would get wrong. Sellers price the two formats independently, the gap runs $40 to $60 a month, and it does not run the same direction every time — one seller charges more for its oral product than for its own injection.
Open the board →Who prescribes it?Plans, not one-off checkouts
The sellers whose own pricing describes an ongoing prescribed relationship — a multi-month ladder, an auto-refill, a membership — rather than a product page that assumes you already have a script.
Open the board →Check the claimWhat the trials actually measured
−14.9% on semaglutide across 1,961 adults, −20.9% on tirzepatide across 2,539 — and the one published head-to-head between them was run in type 2 diabetes, not obesity. What that does and does not settle.
