Accurately calculating potency is essential for anyone working with cannabis, CBD, or custom herbal substances. Whether you’re making edibles, tinctures, oils, or supplements, knowing the strength of your product ensures safe consumption and consistent dosing. The Potency Calculator is a free online tool designed to simplify this process by providing clear and accurate results in just a few clicks.

With this tool, you can calculate:

• Total active compound (mg)
• Potency percentage
• Number of servings
• Desired and actual dose per serving
• Total weight used

This makes it an indispensable tool for home users, dispensaries, and professionals in wellness or alternative medicine.

How to Use the Potency Calculator Step by Step

The Potency Calculator is designed to be user-friendly. Here’s how to get started:

1. Select the Substance Type
   • Choose between Cannabis (THC), Cannabis (CBD), or a Custom Substance.
2. Enter Potency Percentage
   • For cannabis, this is usually listed on product packaging (e.g., 18% THC or 12% CBD).
3. Enter the Total Weight
   • Input the total weight of the substance you are working with in grams.
4. Set Desired Dose per Serving
   • Enter the milligrams (mg) you want per serving. For example, many edibles aim for 5–10 mg THC per serving.
5. Enter Number of Servings
   • Choose how many servings you want to prepare (e.g., 20 brownies, 30 capsules, etc.).
6. Click Calculate
   • The tool processes your data and shows results such as total active compound, used weight, and actual dose per serving.
7. Copy or Share Results
   • You can copy the results to your clipboard or share them directly.

Practical Example

Let’s say you want to make 20 servings of cannabis brownies using cannabis that contains 15% THC. You have 10 grams of flower available, and you want each serving to have 10 mg THC.

• Substance Type: Cannabis (THC)
• Potency Percent: 15%
• Total Weight: 10 g
• Desired Dose per Serving: 10 mg
• Number of Servings: 20

Results:

• Total Active Compound = 1,500 mg THC
• Actual Dose per Serving = 75 mg THC (if all 10 g is used)
• To achieve 10 mg per serving, you’d only need 2.67 g of cannabis out of the 10 g available.

This ensures you don’t waste product and can maintain safe dosing levels.
