Before You Use This Calculator

Welcome to my dosage calculator for cannabis edibles and homemade recipes.

While a calculator is no replacement for lab testing, this tool will help you get a guesstimate of the potency of your cannabis infusions and extractions.

Unlike other online calculators, this calculator hopes to provide more accuracy by accounting for the losses associated with decarboxylation, infusion oils, or extraction solvents.

Before using this calculator, you will need to know two things:

  1. The amount of cannabis you are putting into the recipe – in grams (remember, there are 28 grams in one ounce)
  2. The percent of THCA / THC or CBDA / CBD present in your material (you can input other cannabinoids here if desired)

If you have these numbers available, you can get started with the calculator below; the results are highlighted in pink.

Step 1: Calculate Potency For the Entire Batch

In this first section, you can calculate the potency of your infused product that can later be used directly in your recipe using the second section of this calculator.

Starting Amount of Cannabis Product in Grams
Type of Oil or Alchol Used
Amount of Oil or Alcohol Used in Cups
Account for the loss associated with Decarboxylation?
Check this box if you decarbed your product and want to account for the natural loss associated with the process.

Step 2: Creation Portions/Servings

In this section section, you can add the infusion or extraction you made in step one directly into any recipe.

Frequently Asked Questions

Which number should I enter THC or THCA?

If you’re working with dried cannabis flower that has not been decarbed, you will be inputting the value as THCA and checking the checkbox to account for the loss of decarboxylation if you decarb. If you are working with a prepared cannabis product that already has THC present because it has already been decarbed, you will enter the value as THC and not check the checkbox to associate for the loss of decarboxylation (because it has already occurred). If you have both numbers, simply run the calculation twice, once for each option.

What is a good dose to start with?

Great question! If you have done the math above but still feel unsure where to start, check out my guide to dosing edibles safely and effectively. If you are feeling very lost, you can also check out my beginner’s guide to using cannabis.

How do I calculate the dosage for concentrates?

If your concentrate already comes with a milligram dosage on the label, you do not need to use this calculator. Simply divide the total milligrams of THC by the number of final servings in the recipe you made. For example, if you have a concentrate labeled with 750mg of THC for the entire syringe and add that syringe to a cookie recipe that makes 24 cookies, you would use the following equation: 750/24 = 31.25mg THC per cookie.

  1. Hey Emily
    Can I add citric acid and sugar to this gummy recipe?
    I’m going to try it with coconut oil ( solid )
    I would like to make a sour gummy.

  2. Hi Colin. We have not experimented with coating the gummies in critic acid/sugar, so I don’t have an exact amount to use, but I would start with 1:1 ratio of the two and adjust according to personal preference. Be careful and make sure the gummies are 100% air-dried before adding the citric acid or sugar, or else the gummies will melt. Enjoy your gummy-making experience!
