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:
- The amount of cannabis you are putting into the recipe in grams – remember, there are 28 grams in one ounce
- 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
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.
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.
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.
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.
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.
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.
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.
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.
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.
This calculator is for educational purposes only, but if you are looking for the best way to take your cannabis education to the next level, my Edibles Made Easy Course was designed for you! This course can transform any home cook into a cannabis chef in a few simple steps. Consider it your complete marijuana handbook for the kitchen!

I am getting an infinity result using the calculator, trying to figure out how much 3 grams of 25% thc, 1tsp infused in water (as a tea) would yeild
Hi there Holly,
Thanks for reaching out and I’m sorry to hear you’re having trouble with the calculator. Let’s see if we can troubleshoot this together!
First, it’s important to note that THC isn’t water-soluble. This means that if you’re infusing your cannabis directly into water to make tea, much of the THC (and other cannabinoids) won’t be able to dissolve into the water and will instead remain in the plant material. Because of this, you won’t get a very strong infusion just using water.
However, if you’re using a fat-based medium like coconut oil or butter along with the water to help extract the THC, then we can use the calculator to estimate the potency.
Assuming you’re using 3 grams of cannabis with a THC percentage of 25%, that means you have about 750mg of THC in total (3000mg x 0.25). If you’re making 1 teaspoon of infused oil with this, and assuming complete extraction (which is unlikely but gives us a maximum potential), you’d have a very potent oil indeed!
Please remember these are rough estimates and actual results can vary based on many factors. And always start with a small dose to see how it affects you before consuming more.
I hope this information helps! Please feel free to reach out if you have any more questions or if there’s anything else we can assist you with.
Your calculator never considers using just chocolate, no oil, no infusion, just chocolate and cannabis
Hi there Susan, if you’re making a simple mixture of just chocolate and cannabis, you can select the “No Solvent” option on the calculator. This will help you calculate the strength of your homemade edible based on the potency of your cannabis and the weight of the chocolate you’re using. Remember, the results will be estimates and the actual potency of your edible can vary based on many factors, like the quality of your cannabis and how evenly it’s distributed in the chocolate. If you have any other questions or need further clarification, please don’t hesitate to reach out.
Can I substitute CBG for CBD in the calculator to get CBG potency, I am using White CBG flower – would I total the CBG and CBGA values or just use the CBGA? Thank you.
Hi there Daniel, thank you for reaching out with your question. You’re absolutely right! The calculator can indeed be used interchangeably for CBD and CBG – great deduction on your part! If you’re using White CBG flower, you would want to total both the CBG and CBGA values to get the most accurate potency result. This is because both compounds contribute to the overall potency of the flower. If you have further questions or need more clarity, don’t hesitate to ask. We’re here to help you navigate this process. Take care and happy calculating!
I love this calculator… Thank you for providing it.
I have one question if you don’t mind, where would you put syrups and honey on the chart so I can accurately make calculations?
Hi Dewey. Typically, when infusing honey or syrup, you are adding cannabis concentrates and not having to strain anything out so all the cannabis ends up in the final product. To use the calculator to determine the strength of your final product, you’ll want to select No Oil or Solvent Used, but still enter the amount of syrup or honey used along with the amount and percentage of cannabis used.
I hope this helps. Sending good vibes for your infusion journey!
First I would like to compliment you guys on the first rate presentation of and broad range of information.
Curious how you would use the calculator when infusing cocoa butter.
Hello there, Richard! Thank you so much for your kind words; they mean a lot to us! To use the calculator with cocoa butter, simply input the amount of cocoa butter for regular butter. This will give you the ballpark measurements you need for calculating the potency of your infusion. If you have any other questions, feel free to ask. We’re here to help! Keep exploring and happy infusing! 🍫🌿
