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

Where can I learn more?

    I love this calculator and use it often. I have learned a nice trick for making tinctures with it.

  2. Rick, I’m glad you find this calculator helpful for your tinctures and topicals. It’s versatile and can handle all applications, no need for anything else. Thank you so much for sharing your mL tip! Keep enjoying your tincture-making journey! 🌿

  3. Thanks for all the great information, and great ideas. My question is: What about the strains in edibles? When I buy flower at the dispensary, I look for indica dominant. But even at the dispensary edibles aren’t labeled. Does something happen in the cooking process where the strain makes no difference?

  4. Thank you for your insightful question, David! You’ve touched on an interesting aspect of cannabis consumption through edibles. When it comes to edibles, the strain name or whether it’s indica or sativa becomes less relevant. What’s crucial in cannabis, especially for effects, are the terpenes and cannabinoids present in the plant. However, during the process of making edibles, most terpenes, which are responsible for the plant’s distinct aromas and flavors, tend to be cooked away due to their volatile nature. This means that the unique characteristics of the strain are often not as distinguishable in edibles as they are when consuming flower directly. Therefore, when choosing edibles, it’s more about the overall THC/CBD content and less about the strain’s terpene profile, which is a significant factor in the effects you might experience with flower. So, while the choice of strain might guide your preferences with flower, with edibles, the focus shifts towards potency and the balance of cannabinoids to suit your desired experience.

    I hope this information gives you a better understanding, but please don’t hesitate to reach out with further questions. ☺️

  5. When accounting for volume lost, do I use the original amount that I started with or do I use the new volume to calculate. Example, I infused 16g of flower with 500ml/2.1 cups of MCT oil and ended up with 450ml of MCT oil once strained and completed, would I calculate the 500ml of oil in the calculator for my dosage, or use the finished 450ml for calculating.

  6. Hi Andrew. Great question! For your dosage calculations, you should use the final volume of MCT oil that you ended up with after straining. This will give you the most accurate measurement for your dosage since it reflects the actual amount of oil that now contains the infused properties of the flower. Happy infusing!

  7. Hi,
    When I degrade cannabis for CBN using a InstantPot for the full amount of time you recommend, is all of the THC in the batch converted to CBN ?


  8. Yes Perry, when using an InstantPot on HI for 180 minutes, most of the THC in the batch should convert to CBN. Happy decarbing!

  9. I love this calculator and use it all the time, but I don’t always have/can get 190 proof. Is there something to drop down menu that I could use that would be comparable to vodka?

  10. Hi Rena. The main difference between 190 proof alcohol and vodka lies in the alcohol content, which directly influences the extraction rate. 190 proof alcohol, being 95% alcohol by volume (ABV), offers a much higher extraction efficiency compared to vodka, which typically has 40% ABV. The higher the alcohol content, the more effective it is at extracting. Vodka, at 40% ABV extracts 42% less than 95% ABV, so you can take what the calculator gives you for 190 proof and minus 42%. Hope this helps! Happy extracting!
