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.Â
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.Â
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.Â
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.Â
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.Â
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! First off let me say I love that you provide this for free! Thank you so much!
For the second part of the equation do I need to put in how many teaspoons of cannabutter I’m using or how many teaspoons my entire recipe is, like the total liquid amount of a batch of gummies?
Hi Jennifer. Thank you for your kind words!! We love that you love it!! For “Number of Teaspoons Used in Your Recipe”, you want to enter the amount of cannabutter you’re using in the recipe. Happy cannabis cooking!
Hi Emily
I’m hoping that you can help.
I love your calculators for dosage calculations.
I make tincture using 2 cups 93% alcohol with 1oz of flower.
I then cut the alcohol with water so the tincture has a 20% alcohol.
Is there a way to calculate THC / CBD after the water is added?
Thank you for any assistance you can give.
Richard
Hello Richard! We’re thrilled that you’re finding our calculators helpful for dosage calculations. Just to clarify, the total THC/CBD content will remain the same, but the strength per serving will be affected. For example, if you start with 2 cups of tincture at 500mg and divide it into 20 servings, each serving would contain approximately 25mg. Now, if you add 2 cups of water, the total content will still be 500mg, but the liquid volume will increase to 4 cups. As a result, each serving would be diluted to about 12.5mg. I hope this makes sense! Feel free to reach out if you need further clarification! Happy Extracting!
Emily, Firstly, Thank you for a brilliant site. Can I add though, it would be so good if instead of ‘cups’ in the oil / butter section you used grams and instead of teaspoons in the servings you used grams. This makes the weight universal and precise as cup and spoon sizing differ depending on your country. Bakers will only use weight in a recipe but this calculator switches between grams and cups / spoons making it variable.
Thank you so much for sharing your thoughts, Gab. This is an excellent suggestion and I will send this off to the team to see if we can’t get grams added 😀 Makes more sense for sure!
Hello Emily,
Thank you for the best tools and information out there. It’s been a great help to a newbie infuser.
My question is, if I use 1 cup of MCT oil or butter in my infusion, and end up with 2/3 cup after straining, what would be the total thc in the finished product be based on…Total oil used (1 cup), or the yield after the infusion (2/3 cup)?
Also, I own an Edioven, and their instructions state to decarb in the unit for 70 minutes at 240° – and to infuse oil at 180° for one and a half hours. Most infusion recipes I’ve read say to infuse for 2 to 4 hours, and decarb instructions I’ve read recommend around 40 minutes.
In your opinion, should I infuse for longer and/or decarb for less time to get the best results?
Hello Michael, great questions! When it comes to calculating THC content in your infused oil, you would base it on the yield after the infusion, which is 2/3 cup in your case. As for your second question, the decarb and infusion times can vary based on different factors, such as the type of cannabis you’re using, its THC content, and the specific appliance you’re using. While the Edioven instructions recommend certain times and temperatures, other sources may suggest different ones. It might be worth experimenting with different times and temperatures to see what works best for you. Without lab testing, it’s just a big guess. I hope this helps! Happy infusing! 🌿
Hi Arthur. We’re thrilled you found the calculator helpful! When you start with 1 cup of coconut oil and end up with 3/4 cup after processing, you should use the 36 teaspoons (which is the amount you’re left with) for your recipe. The potency of your infused oil is concentrated in the amount of oil you have after cooking and straining, not the original volume you started with. I hope this clears things up! Happy infusing!
Hello,
Thank you for all of the information that you are providing.
I made the cannasugar I used your freezer recipe
2 cups of sugar, 1 cup of 190 proof alcohol, 14 g of flower at 25% THC.
If I use the Calculator right, it looks like it’s going to be 60 MG per teaspoon for the entire batch? Is that correct? Now I want to use some of the sugar to coat my gummy’s. I am not sure how I figure out the potency of the sugar once it is on the gummy? I realize that I would add whatever that number is of sugar to the potency of the gummy. I just want to make sure I’m starting out with the right number for the sugar.
