How-To calculate edible dosage backwards is one of the most useful skills for anyone making cannabis edibles at home. Instead of guessing how strong your batch will be, you start with your target milligrams per serving and work back to the exact grams of cannabis you need. This 3-step guide walks you through the math with real examples so every cookie, gummy, or brownie comes out at the potency you want.
Why How-To Calculate Edible Dosage Backwards Matters
Most edible guides start with a set amount of cannabis and tell you the potency after infusion. But with an edible dosage calculator approach, you flip the script — starting with the end goal of exactly how strong each serving should be. This gives you precise, repeatable results whether you are making cannabutter cookies, infused gummies, or any other cannabis recipe.
3 Numbers for Your Edible Dosage Calculator
Before you run the edible dosage calculator, gather these three pieces of information:
- Number of servings your recipe produces (e.g., 20 cookies)
- Desired milligrams per serving (e.g., 25mg THC per serving)
- THC percentage of your cannabis flower or concentrate (e.g., 20% THC)
You also need to account for potency loss during decarboxylation and infusion. A standard estimate is 30% loss, meaning you retain about 70% of the total THC through the process.
Step 1: Set Your Target THC Per Serving
Multiply servings by your desired dose. For 20 cookies at 25mg THC per serving, you need 500mg of THC total in the finished batch.
