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, 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!
Eoghan
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!
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.
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!
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
Hi Steve. You can enter the 7g and check the box for decarboxylation and it’ll take the loss into consideration. Happy decarbing!
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?
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!
Very easy to use and understand. Was able to quickly calculate our homemade butter and recipe milligrams with this tool. Thank you!!
Hi Allison. Thank you for your feedback! We love hearing how we help other’s edible experiences! Happy infusing!
