Step 1: Calculate Potency For the Entire Batch

In this first section, you can calculate the potency of your entire batch of an infused product, such as cannabutter or cannabis oil.

This large batch can later be used in your recipe using the second section of this calculator.

If you’re not sure what information to put here, scroll down and read the How to Use This Calculator section below.

How to Use This Calculator

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 gramsremember, 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.

Why You Will Love This Tool

Hello and welcome to my dosage calculator designed to help you estimate how much THC or CBD is in your edibles and homemade recipes. 

If you’re like the members of my Well With Cannabis Community – chances are you love making your own cannabis-infused edibles! 

Not only can you save money when you make incredible recipes at home, but you can also control the ingredients and strength of your edibles.

But how exactly do you determine the potency of your edibles? 

If you know the cannabinoid content of your material and how many grams of weed you’ve used, you can use this handy edibles dosage calculator to do the math for you!

This edibles calculator will then help you determine your own edibles’ CBD or THC content based on the number of servings made.

Not only does this help you determine the THC potency of your homemade marijuana edibles, but it also helps you avoid a dose that is too high, which could result in unpleasant side effects.

Frequently Asked Questions

What if I don’t know how much cannabinoids are in my material?

This is the hardest part for many people! If you purchased cannabis flower from a licensed dispensary, that flower should be accompanied by lab testing, which shows the percent of THC or CBD in the flower. Unfortunately, different labeling regulations do not make this information universal. If you grew your own cannabis at home, knowing the potency of THC or CBD will be impossible without lab testing. You can, however, research strain guides that provide a general idea of the total cannabinoids in a specific strain.

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. Suppose you are working with a prepared cannabis product that already has THC present because it has already been decarbed. In that case, 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. 

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 THC milligrams by the 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.

Why are there different values for different solvents?

Great question! We are using different values to account for extraction efficiency. For example, olive oil will have a different extraction efficiency than coconut oil. A fat-based product will have a different level of efficiency than alcohol, which is what we are trying to account for here.

Does it matter what type of butter I use?

If you’re calculating the THC or CBD dosages for a cannabutter recipe, it shouldn’t matter whether you use regular butter or unsalted butter. What will matter is the amount of butter you use. 

What is a good dose to start with?

The correct dosage is unique to each person, as we all have endocannabinoid systems that control our tolerance level. If you have done the math above to calculate the total mg of THC but still feel unsure where to start, check out my guide to dosing edibles safely and effectively. I recommend starting with the microdosing method. As a good rule of thumb, low doses of 1-3 mg THC are a good place to start. If you are feeling lost, you can also check out my beginner’s guide to using cannabis. If you’re feeling and need to know you’re consuming an exact dose, my most popular edible product, Micro Gummies, can help you get started. 

What if I don’t feel the effects of edibles?

A segment of the population reports feeling no effects from cannabis consumed in edible form or only when a very high dose is consumed. This can depend on a variety of factors, including your individual metabolism, what you’ve eaten, the decarboxylation process, and the potency of edibles consumed. If you do not feel the effects of edibles despite consistent doses and correct time intervals, check out this guide. Ultimately, you may need to explore more efficient ways to consume cannabis, such as cannabis-infused oil used as sublingual tinctures

What if I consume too much THC?

My goal in providing this calculator is that you can avoid consuming too high of a THC dose. Consuming too much THC is uncomfortable and can alter your ability to perform basic functions. Adverse effects may include dry mouth, racing heart, and even a panic attack. That is why it is important to exercise a side of caution and use the right amount of cannabis before getting started. Seek professional medical advice if needed.

Do you have other calculators?

I have had requests for a topical dosage calculator and a tincture calculator. Still, this calculator here can work and is a great option for calculating total THC for both tinctures and topicals

  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.
    Colin Alexander

  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!

  3. Hi Emily, I am using Bacardi 151 to try the QWET method for the first time only because that is what I have on hand. Do you know how to calculate how much less potent the batch should be vs using 190 proof?

  4. Hi Cheryl. 190-proof is roughly 20% stronger than 151, so after you determine the strength using the 190-proof option, subtract 20% from your final number. I hope this helps!

  5. Hi Saidah. Our edible dosage calculator is free to use online. Thank you for your interest!

  6. How would we determine the CBN yield in MG after we decarb and infuse – assuming we know all other factors like THC%?

  7. Hi Cody. If you decarb properly for CBN – 240ºF for 180 minutes – you can expect close to 100% conversion which should match the same percentage as the THC. I hope this helps!

  8. Hi Guys,

    Three part question for you.
    1. Can I use your calculator to work out the dosage of my homemade oil? Aiming to calculate the strength of each drop
    2. I want to make a high strength cbd with a fairly low non intoxicating thc level. I will be using approx 10 grams of 40% cbd weed and approx 3.5 grams of 15% thc weed in approx half cup of MCT oil. When using the calculator to determine the strength should I enter the cbd and thc in two separate calculations and add them together because I’m not using equal weights of both.
    3. After making the oil and straining the plant material out should I do the calculation again to allow for the 10% or so loss in liquid left with the plant material

    Thanks so much

  9. Hi there Eoghan,

    Thank you for your excellent questions! I’m glad you’re finding our resources helpful and are taking the time to carefully plan your homemade oil.

    Yes, our calculator can certainly help you determine the dosage of your homemade oil. Just remember that the results will be estimates based on the information you input. The strength of each drop will depend on the total volume of your oil, so you may need to do some additional calculations if you want to get very specific.

    Your approach sounds solid. The calculator has an option to input both CBD and THC at the same time, but since you’re using different amounts of CBD-rich and THC-rich cannabis, it would be best to perform two separate calculations to determine the total amount of each cannabinoid in your oil. Then you can add these together to get the total potency.

    As for your third question, it’s true that some of the oil will remain trapped in the plant material after straining. If you’d like to account for this loss in your calculations, you could estimate a 10% reduction in the total volume of your oil. However, keep in mind that the actual loss may vary depending on factors like the fineness of your grind and the method you use to strain the oil.

    I hope this helps! Feel free to reach out if you have any other questions or if anything needs further clarification. We’re here to support you in your journey towards creating the perfect homemade oil.
    Best of luck with your cooking!
