How the Wegovy Pen Calculator Works
This Wegovy calculator helps estimate semaglutide (GLP-1) dosing for weight loss, including clicks, pen usage, and cost.
Step 1: Select Your Pen Size
Choose the Wegovy pen strength prescribed to you (0.25mg, 0.5mg, 1mg, 1.7mg, or 2.4mg).
Step 2: Enter Your Desired Dose
Input the amount you want to inject each time. This might be smaller than your pen size if you're splitting doses.
Step 3: Add Cost (Optional)
Enter what you pay per pen to see potential savings. Skip this if you just want injection counts.
Step 4: Choose Dosing Frequency
Select how often you'll inject (every 7 days is standard, but some people inject more frequently with smaller doses).
Step 5: Calculate
Click the Calculate button to see:
- Clicks needed per injection
- Number of injections you'll get from one pen
- Cost per injection and weekly cost
- Total savings compared to standard dosing
- How long your pen will last
- Medication levels in your system (high and low)
Example: If you have a 1.7mg pen and take 0.6mg doses instead of the full 1.7mg, you can get approximately 11 injections instead of just 4, potentially saving hundreds of dollars per month.
Remember
Always follow your doctor's guidance before changing any dosage. This calculator is for educational purposes only. Any dose adjustments should be discussed with and approved by your healthcare provider.
Each Wegovy FlexTouch pen contains 4 full doses of your prescribed strength. This means:
| Pen strength | Total medication |
|---|
| 0.25mg pen | 1.0mg total medication |
| 0.5mg pen | 2.0mg total medication |
| 1.0mg pen | 4.0mg total medication |
| 1.7mg pen | 6.8mg total medication |
| 2.4mg pen | 9.6mg total medication |

Why the Wegovy Pen Calculator Needs
Cost reduction and making your pen last longer are the primary reasons patients explore dose splitting. By using smaller doses, one pen can last weeks or even months longer, potentially saving more than $500-$800 per year.
Smaller, more frequent doses may also help reduce side effects such as nausea, vomiting, and stomach discomfort. Many patients find that splitting their weekly dose into smaller amounts helps their body adjust more gradually.
Common benefits reported:
- Significant cost savings (+$500-800/year)
- Pen lasts 2-3x longer
- Less intense nausea
- Better tolerance during titration
- Extended supply during medication shortages
Important: Only adjust doses under medical supervision.
