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!

Hi Emily, I hate to ask a stupid question but unless i missed it, i havent found an answer in your instructions for calculating potency. What are we counting when you say “number of teaspoons in your recipe”? Number of teaspoons of oil? Number of teaspoons of dough to make a cookie? Either number i use seems to make the potency very high. Is there something else i forgot to count? Thanks for reading my question.
Hi Janet. There are no such thing as stupid questions. ☺️
Number of Teaspoons Used in Your Recipe = The amount of teaspoons of infused oil you are using in the recipe.
Total Number of Servings In your Recipe = The amount of individual servings in your entire recipe.
If you feel like your numbers aren’t right, reply to this email with your numbers and I’ll take a look over it. I hope this helps!
Hi Emily. Great site. Delighted to have come across it while on hols in the US. LA, NY, Chicago, Memphis and NO.
Q 1. If i infuse with MCT and and then decide to fill the capsules without filtering the infusion will each capsule be more potent that if i just filter the MCT infusion into each capsule? It seems a shame and a waste to lose 10%+ oil sitting in the of filter as well as the decarbed/infused leaf.
Q2. If I make Green Dragon, which I’m going to, can this be filled into gelatin based capsules or will it break them down? If yes …any alternative type of capsule?
Cheers
John
Hi John. We’re glad our site has been helpful for you while on holiday!
Regarding your first question, if you choose not to filter the MCT infusion before filling the capsules, each capsule may indeed be more potent. When infusing, the oil can only absorb so much from the plant material. If you leave in the plant material, you’re getting 100% potency of the flower. Filtering the infusion helps remove any residual plant material and helps improve the taste and texture of the final product, but by not filtering, you will get an increased overall potency. When making capsules, taste and texture don’t necessarily matter, so I love the idea of not filtering out the plant material.
As for your second question, gelatin-based capsules are not the best choice for filling with Green Dragon since the alcohol content could potentially dissolve or degrade the gelatin capsules. Consider using vegetable-based or vegan capsules, which are made from materials like cellulose or agar. These types of capsules are generally more resistant to the effects of alcohol.
I hope this helps! If you have any further questions, feel free to ask. Happy infusing!
Hi Emily,
I am looking for more information on how to use home made concentrations. I started with 5 ounces of 12.82% THC and 5 cups of EverClear alcohol. I made the tincture in the Magical Butter Machine. I made 31 ounces of tincture. I figured that the final result was 15,360 mg of THC. I evaporated the alcohol down to 5 ounces of concentration. This is where I am stuck. How do I figure how much of the concentration is needed to make 100 gummy bears which contain 3 ml of liquid each. Is there a formular to figure this out? This is the large size gummy bear mold. If you need more information just let me know.
Thanks for the help.
Jane
Hi Jane. Are you using Emily’s Cannabis Gummies Made With Tincture, FECO, or RSO recipe? That recipe makes approximately 10 fluid ounces, which is 300ml. This recipe calls for 4oz of tincture, but you’re evaporating off the alcohol, so you can definitely use all your tincture if you’d like. Based on your calculation of 15,360mg THC for the total batch, each gummy will be 153.60mg. Those pack quite the punch!!
I hope this helps clarify things! Remember, it’s always best to start low and go slow when it comes to cannabis edibles, especially when sharing with others. Always label your homemade edibles clearly to avoid any accidental overconsumption.
Emily. What’s the typical about of oil used for 7 grams of decarbed flower? I typically use a 1/2 cup of either coconut or vegetable. And for my recipe, I typically use the whole batch (24 tsp) and make 90 to 100 pieces. Usually milk chocolate melted and place into molds.
Hi Mike. We recommend using 1/2 cup of oil with 7 grams of flower. You can refer Emily’s Cannabis Flower-to-Oil Ratio Guide & Printable Chart for other amounts as well. Happy infusing!
Hey Emily… when calculating potency do you use the amount of oil that you start with or the amount of oil that you end up with after infusion? Will be using a Levo 2.
Hey Chris! That’s a fantastic question. To ensure precise potency, it’s important to consider the amount of oil used BEFORE the infusion process begins.
