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!

I just found your site and can’t stop reading. There is so much information! Thanks for that and the calculator is priceless. I do have a question though.
When making Canna-butter I use 7g of Shake at 20% THC for 2 sticks of butter. I am making 1 batch of cookies that needs 1 stick of butter and yields 24 cookies. How would I enter this into your calculator to figure out per serving?
Hi Eric. You can enter 7g @ 20% THC with 1 cup of butter. 1 stick of butter is 24 teaspoons, and you’ll have 24 servings. I’m calculating 22.73mg per cookie. Let me know if you get the same. Thank you so much for your support. Emily works hard to continuously improve the cannabis education she offers, and it’s always rewarding to receive such wonderful feedback.
Can I use my cannabutter right away or does it need to be refrigerated first?
Hi Candy. There is no reason why you can’t use your cannabutter right away.
Emily, I come to you for advice on canna-math. I want to make my own cbd/thc tincture that I can infuse with reiki. So if I have a cbd 3.5 g and 7 grams of flower would that be a 1:2 ratio?
That is what I did with the 1:1 but what I want is where thc is higher than cbd for my nighttime use.
Hi Shaunna. Your math is accurate. ☺️
Hi! I am looking to make gummies from kief, but am having a horrible time trying to find an equation or calculator to determine how strong my gummies will be. Let’s assume I have 4 grams of kief derived from weed with an average strength of 19%. My gummy recipe makes 140 gummies consistently. I usually infuse 28g (1 oz) into 1/2 cup (1 stick) of clarified butter and each gummy comes out around 60mg/gummy. I want to try it with kief, but want to understand how to calculate the potencybefpre I do..
Thanks!
Hi Mark. Kief can be as potent as 70%, so you want to use a higher number as such for the THC% in the calculator. Are you infusing butter or adding directly to the gummies?
I make gummies for sleep. I can’t figure out the dosage part even with the calculator. I use your recipe
I made 3 cups of coconut oil with 60 grams of bud
I triple your recipe and make about 250 gummies (2 cups oil)
I decarb for 60 mins till chocolate brown to change to CBN
In this I also add 30 gummies that I Made with regular decarb and everclear
Formula for those is 30 grams of bud 2 cups everclear. I use 1 cup and take the alcohol out by heat and add the same amount of jello etc and thus makes 250 gummies
Each gummy is :5 tsp
Can you help me with calculating
Thank you
Ps your recipe is the best after trying many others
Hi Kathy. I can help, but do you know the strength of the cannabis you used? The percentage of THC? – We are so glad you love this recipe! Gummies can be finicky, but Emily’s recipe makes it so easy!
