Questions about this calculator.

It projects the average results from the SURMOUNT-1 trial for each tirzepatide dose (5 mg ≈ 15%, 10 mg ≈ 19.5%, 15 mg ≈ 20.9% of body weight at 72 weeks). It is an educational estimate, not a prediction — your individual results will vary.

How much weight can you lose on tirzepatide?

In clinical trials, adults lost an average of roughly 15–21% of their body weight over 72 weeks depending on the dose. Enter your current weight above to see your personalized projection.

Is the calculator free to use?

Yes. It is completely free, requires no sign-up or email, and runs entirely in your browser.

Why does a higher dose show more weight loss?

Higher maintenance doses produced greater average weight loss in clinical trials, which is why the projection deepens as you move from 5 mg to 15 mg. Your physician determines the right dose for you.
