Are you working to try and calculate the amount of THC or CBD in your homemade cannabis creations? If you know the potency of your flower and how much you used, we can help with the math! Here you can use our most accurate edible dosage calculator to help you guesstimate the potency of your cannabis edibles, recipes, and homemade creations.

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. Hi Emily, love the content and was going to try your gummies recipe. Is MCT oil or coconut oil best for gummies? I already have infused MCT oil made up I can use but maybe coconut oil helps them solidify.

    Any help would be appreciated!


  2. Hi Eoghan. MCT oil has a more liquid consistency, which might result in softer gummies. If you prefer your gummies a bit firmer and chewier, coconut oil could be the way to go. I hope this info helps you in your gummy-making adventure!

  3. I love your site and I would really like to start making edibles in a more precise manner but I’m not sure how to go about finding the content of THC or CBD in the flower or trim that I will be using.
    I want to be able to control the dosage without over doing it or not using enough.

    My question is,
    to use the ccalculator how do I determine the amount of THC or CBD’s after decarboxylation or can this only be done through a laboratory?
    I hope you can help me with this one and give me some kind of direction.

  4. Hi Steve. Lab testing will provide the most accurate results, but there are other ways. The cannabinoid content based on the percentage should be listed on the packaging or provided by the supplier. If you grow your own, the breeder should provide the expected cannabinoid content with their seeds. If you don’t have either of these, we typically recommend using 15% for home grown and 20% for dispensary product. If you use Emily’s Edible Dosage Calculator, that can help determine potency after decarboxylation. I hope this helps!

  5. Hi Emily! Great site I hope you are flourishing! I started with 7g of flower. It went down to 3.36 during carbox. I was wondering which weight would produce the most reliable output in your calculator? Citrus Tsunami 13/1

  6. Hi Steve. You can enter the 7g and check the box for decarboxylation and it’ll take the loss into consideration. Happy decarbing!

  7. I have 3 gms. of decarbed cannabis in 1/2 c. of coconut oil.
    I froze it in an ice cube tray – 4 cubes total.
    I am familiar with portioning THC OR CBD rectangular jelly bombs quite accurately for controlled consumption and it works. I want to do the same. I need to know what the strength of this batch is in order to be close to my current dosing. I am currently using 2.5 mg. of CBD and 1.25 mg of THC as my dosing. can you help me determine a similar outcome?

  8. Hi Ed. Your final outcome is dependent on the strength of cannabis you are starting with. Are you using two strains, a CBD-Dominant and a THC-dominant strain? Do you know the strength of your cannabis?

    For easy math purposes, let’s say your cannabis has an average of 10% THC, which means your 3g of cannabis contains about 300mg of THC. You’ve mentioned that you’ve divided your cannabis-infused oil into 4 cubes, which means each cube contains approximately 75mg of THC.

    Did you strain the cannabis from the coconut oil or did you leave in? Decarbing and straining both reduce the overall strength of the final product so these numbers are just to give you an idea of how to determine what you’re working with.

    There are a few components at play here, but knowing the strength of the cannabis you are working with is essential in precise dosing. If you do know, I can help you even further. Just let me know! Happy infusing!

  9. Very easy to use and understand. Was able to quickly calculate our homemade butter and recipe milligrams with this tool. Thank you!!

  10. Hi Allison. Thank you for your feedback! We love hearing how we help other’s edible experiences! Happy infusing!
