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!

Thank you for the calculator and information but you probably don’t ship outside of Canada.🙂👍
You are most welcome, Jerry! Unfortunately, we cannot ship to Canada at this time 😭
Hi Emily! I’m a huge fan and greatly appreciate your work. Your recipes have empowered me to heal myself, friends, coworkers and neighbors.
I’m trying to recreate your calculator in my own google sheets formula so I can properly calculate my tincture dosage. I need to convert some of the measurements from cups to fluid ounces and tsp to mL to make my life easier. Math is not my forte and I’m piecing together what I can using ChatGPT, which seems to have quite different numbers from your output.
Would you be willing to share the backend information for this calculator so I can use it as a guide to create my own? I would be eternally grateful!
Hi there! 😊 Thank you so much for your kind words and your support—I’m thrilled to hear that my recipes have been so helpful to you and your community. I’m super impressed with your initiative in working on your own Google Sheets formula! I had a hired someone (much smarter than me) to create the calculator, so unfortunately, I don’t have access to that information to share. However, I’d be happy to offer guidance to the best of my ability if you’re looking for something specific!
Hi Helen, thank you for sharing your experience! It sounds like you’re on the right track with your calculations! If you have any more questions as you continue experimenting, feel free to ask! Best of luck with your journey to find relief.
Thank-you so much for all your valuable information. I have an array of pain, inflammation and neuropathy due to a near fatal car accident. After a circus of pharmaceuticals I was advised also to use alternatives. I’ve used cannabis recreationally for awhile and have started making my own edibles for medical use. I’m still a little unsure of calculating FECO concentration. If my tincture using 2 cups of Everclear is approximately 5132.20, yield is about 3 ml of FECO per cup
Do I divide the 5132.20 by 6 (syringes 1 ml each) ? That would be 855.36 per syringe.
If using the 1 ml in the recipe then divide the 855.36 number by the number of servings ?
Just trying to be sure of my thought process here. Helen
i have a question. im making thca gummies. im having a problem with your calculator. its operator error, can i just ask you instead?
i have 42 grams of thca or 1 1/2 oz
i need my gummies to be 40-60 mg each of thc*a
the weed is 29% thca
i have gummy molds that hold 1 teaspoon each an i can make 70 gummies and 70 gummy worms at 1 time.
im so confused to how much canna oil i should add because these gummies dont have a thc % per edible?
please halp!
Hello, Air Lee. No worries, I’m here to help! 😊 You can definitely use the calculator with the THC option, just be sure not to check the checkbox for decarbing loss since you’re working with THCA. With 42 grams of THCA at 29%, aiming for 40-60 mg per gummy is totally doable. Based on your setup of making 140 gummies total, I’d suggest using about 13.65 grams of your THCA material. This calculation should give you around 43 mg per gummy. Remember, it’s always good to start with a small batch to test the potency. If you have any more questions, feel free to ask!
Thank you so much for not only calculator, but all the knowledge you pass on.
Thank you so much. This calculator helps so much. It’s way easier for me to make smaller portions and have a couple than one and be anxious and paranoid for hours. It’s a little difficult to uningest
And it’s easier to let my friends and family try as well seeing as we all have different tolerance levels.cant wait to try make gummy bears. Already made cookies muffins brownies and bars. The candies are next
