📌 Quick Answer: Clinical trials show Mounjaro (tirzepatide) produces greater average weight loss than Ozempic (semaglutide) — roughly 20–22% vs 8–10% at diabetes doses. However, Mounjaro typically costs more per month. Use this calculator to compare time-to-goal and total cost for your specific targets .
📋 Key Takeaways — Mounjaro vs Ozempic 2026
Mounjaro: 20–22% weight loss (trial benchmark)
Ozempic: 8–10% at diabetes doses
Mounjaro targets two hormones (GIP + GLP-1)
Ozempic targets one hormone (GLP-1)
Mounjaro self-pay: ~$499–$1,899/mo
Ozempic self-pay: ~$199–$399/mo
2026 federal pricing aims for $350/mo starter doses
ℹ️ This comparison uses clinical trial benchmarks from SURMOUNT-1 (tirzepatide) and STEP 1 (semaglutide), plus 2026 US self-pay pricing. It is not medical advice .
💡 Important: Ozempic is FDA-approved for diabetes, not weight loss. Wegovy (same drug, higher dose) is the weight-loss version. This calculator uses Ozempic data as a proxy.

How the Mounjaro vs Ozempic Calculator Works
This Mounjaro vs Ozempic calculator 2026 compares the two most popular GLP-1 medications on three dimensions: weight loss potential, time to goal, and total cost. It uses clinical trial benchmarks and your entered monthly costs to give a personalized comparison .
The weight loss model uses trial averages: Mounjaro's SURMOUNT-1 data shows 20–22% body weight reduction, while Ozempic's diabetes-dose data shows 8–10%. The time-to-goal calculation applies these percentages as an exponential approach to plateau, matching published trial curves .
Total cost = monthly cost × months to goal. If your goal exceeds a medication's trial maximum, the calculator flags it as unreachable rather than extrapolating beyond the data .
Why Mounjaro Produces More Weight Loss
Mounjaro (tirzepatide) is a dual GIP/GLP-1 receptor agonist, while Ozempic (semaglutide) targets only GLP-1. The additional GIP action is believed to improve how the body processes sugar and fat, contributing to greater weight loss .
A 2026 randomized study in Iraqi T2DM patients confirmed this: tirzepatide significantly reduced body weight, HbA1c, LDL, triglycerides, and systolic pressure compared to semaglutide over 24 weeks . A separate indirect comparison found tirzepatide 10–15 mg was associated with greater weight reduction than semaglutide 2.4 mg .
2026 US Pricing Reality
Self-pay prices for these medications vary dramatically by provider and dose .
Federal agreement (2026): $350/mo cash-pay starter doses; $245/mo Medicare with $50 copay [citation:11][citation:15]
The wide range reflects introductory offers, maintenance dosing, and whether you're using telehealth, a pharmacy discount card, or insurance. Always verify the actual price you'll pay before committing .
Which Should You Choose?
There's no universal answer. Consider :
If your goal requires >12% weight loss: Mounjaro (or Wegovy, the weight-loss version of semaglutide) is more likely to get you there.
If cost is the primary constraint: Ozempic's lower monthly price may make it the pragmatic first choice, even with slower results.
If you have type 2 diabetes: Both are approved, but Mounjaro shows stronger A1C reduction in trials.
If you have heart concerns: Semaglutide has strong cardiovascular outcome data; discuss with your doctor.

❓ Frequently Asked Questions
Which is better for weight loss, Mounjaro or Ozempic?
Clinical trials show Mounjaro (tirzepatide) produces greater average weight loss than Ozempic (semaglutide). Mounjaro trial data shows 20-22% body weight reduction, while Ozempic shows 8-10% at diabetes doses. However, Wegovy (higher-dose semaglutide) reaches 15-17% .
How much does Mounjaro vs Ozempic cost in the US in 2026?
Self-pay prices vary widely. Hims & Hers lists Mounjaro at $1,899/month and Ozempic from $199/month. Federal agreements announced for 2026 aim for $350/month cash-pay starter doses and $245/month Medicare pricing with $50 copays [citation:3][citation:11].
How long does it take to reach goal weight on Mounjaro vs Ozempic?
Using trial benchmarks, Mounjaro typically reaches a 20% weight loss goal in about 13-14 months. Ozempic caps around 10-12% weight loss at standard diabetes doses, so larger goals may be unreachable without switching to Wegovy or higher doses [citation:5].
What is the difference between Mounjaro and Ozempic?
Mounjaro (tirzepatide) is a dual GIP/GLP-1 receptor agonist, while Ozempic (semaglutide) targets only GLP-1. The dual action of tirzepatide is believed to contribute to its greater weight loss effects. Both are once-weekly injections .
Can I switch from Ozempic to Mounjaro?
Yes, patients can switch between GLP-1 medications, but protocols vary. Your prescriber will determine the appropriate starting dose and titration schedule. Do not switch without medical guidance .
💡 Expert Tips for Mounjaro vs Ozempic
Tip #1: Don't choose based on weight loss alone. Insurance coverage, side effect tolerance, and cardiovascular history matter just as much .
Tip #2: Verify the actual cash price before committing. Introductory offers often expire after the first month or two .
Tip #3: If your goal requires more than 12% weight loss, Ozempic at diabetes doses likely won't get you there. Discuss Wegovy or Mounjaro with your doctor .
Tip #4: Real-world results typically land at 60–80% of trial peaks due to adherence and lifestyle factors. Budget for a slower timeline .
Tip #5: Both medications require gradual titration to minimize side effects. Don't rush the dose escalation .
