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.

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!

In the following field- TOTAL MG OF THC PER TEASPOON
35.72
Would the teaspoon refer to the tincture ( 190 proof) or a teaspoon of the FECO?
Hello Brenda! That would be for a teaspoon of the tincture. If you evaporate off all of the alcohol, the “total mg of THC” line will reflect what is in your FECO. I hope this helps!
LOVE the site/calculator! As a newcomer to making my own edibles, this is such a great site because you break everything down in simple terms…I have a curveball for you though, I just can’t wrap my noob head around figuring out ANY approximation for my dosing!
As a noob, Google has been my friend. I made coconut infused oil (450mL) using trim from a ~20%THC harvest, recovered as waste after 2 rounds of bubble hash making (cold water extraction) as Google said the trim is still suitable for edibles.
After drying and decarboxylating the waste, I had a starting weight of 58g.
Any thoughts on how I’d approach this 58g of keifed trim in 450mL oil from a dosing standpoint? Google mentioned the waste is less potent as starting material hence the high ratio of weight to oil…sorry for the extended typing lol. I’m just so confused
Hey Jay! Thanks so much for you kind words. Unfortunately, there is literally no way to calculate an approximate dose at this point. The best option, depending on how bad you really want to know, would be to send it to a lab for testing. Potency samples run about $60. Otherwise, it truly is just a wild guess.
I have question about using the calculator for determining dosage when wanting to use just decarbed cannabis i.e. a firecracker.
Using 10 gm of cannabis at a 20% strength, and no oil or alcohol used, I get a total of 1754 mg of THC (after accounting for the loss during decarboxylation.) This would be 175.4 mg per gram of cannabis, which seems awfully high.
Given that you suggest on the firecracker recipe page starting with 1/4 teaspoon (which is about 1 gm), this seems to be way too much. What am I missing? Thanks!
Hey Torsten! You’re not missing anything, you are completely correct with your math. I’m going to adjust the firecracker recipe to call for less, because yes, that is super potent for some people 😀 Thanks for pointing that out!
Thank you for all of the work you put into this calculator and all of your articles! If I’m infusing milk, should I click “no solvent?” Thanks again!
Hello Lauren! If it’s a full fat milk, I would choose butter or oil as the solvent used! I will look into adding a milk option in the future 😀
Could you please do a metric version? I’m happy to help if needed
Hello Astrid! Thank you for the request, we will work on this for the 2023 season 😀
