These free GLP-1 tools turn published evidence and real prices into numbers you can use before you talk to a healthcare provider. Each one answers a single question: how much weight people lost in trials, whether your BMI matches the FDA label criteria, or what a program will really cost you.
What each GLP-1 tool does
| Tool | The question it answers | What it uses |
|---|---|---|
| GLP-1 weight loss calculator | How much weight did people lose in the main trials, applied to my weight? | Average results of SURMOUNT-1, STEP 1 and SCALE |
| BMI calculator & GLP-1 criteria check | What is my BMI, and does it match the criteria on the Wegovy® and Zepbound® labels? | CDC adult BMI categories, FDA label criteria |
| GLP-1 cost calculator | Which of my quotes is cheapest over 3 to 24 months? | Only the prices you enter |
| Weight-loss program price tracker | What do telehealth programs charge right now? | Public pricing pages of 15 programs and manufacturer pharmacies, dated |
Who these tools are for
They are built for US adults who are considering prescription weight-loss medication, or already taking it and comparing options. A sensible order:
- Check your BMI against the label criteria.
- Look at the trial averages to set realistic expectations.
- Collect quotes, using the price tracker as a starting point.
- Compare those quotes over several months in the cost calculator.
They are not designed for people under 18 or during pregnancy. If you have a history of an eating disorder, please talk to a clinician before focusing on weight numbers.
Your privacy: nothing leaves your browser
The three calculators run entirely in your web browser. The numbers you type are never sent to our server or to anyone else, and they are not saved: reload or close the page and they are gone. You don’t need an account or an email address to use them.
What the tools can’t do
They give general information, not a diagnosis or a treatment plan. Only a licensed clinician who knows your health history can say whether a medication is right for you. Our medical disclaimer explains this in more detail, and our methodology shows where every figure comes from.
