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!

Emily & Team, Thank you for an incredibly informative web site! I have a quick question about the “natural loss” due to decarboxylation…which the calculator seems to have established at a constant of 12.3% loss, or 87.7% efficiency.
The calculator also accounts for some “loss” due to the “infusion efficiency” of the selected Oil or Solvent, i.e, Butter has an 88.86% efficiency, or 11.4% loss.
So, for example, starting with 3.5g of cannabis, with THC/CBD at 20%/5%, in 1 cup of butter, and Decarb Loss Checked:
Calculator Yields: Total THC/CBD 545.51mg/136.38mg
Ardent claims “97-100% activation” using their machine…Such that using the same quantities/qualities, and adjusting the Decarb Loss from 12.3% to 1.5% (~98.5% efficiency of machine): Total THC/CBD 612.69mg/153.17mg. An increase in THC/CBD of 67.18mg/16.79mg overall.
My question is, can/should I replace the constant used for decarb loss from 12.3% with 1.5% for a more accurate measure…or am I looking at this incorrectly?
Thank you!
Hi Bill! Thank you for reaching out with your great question! When Ardent mentions a “97-100% activation” rate, they’re referring to the efficiency of converting acidic cannabinoids, like THCA, into their neutral, more potent forms such as THC. This conversion is crucial for achieving the desired effects.
The 12.3% loss has to do with the decarboxylation process itself. Decarboxylation involves removing a carbon dioxide molecule (CO2) from the cannabinoid. When CO2 is removed, it turns into gas and escapes, which results in the cannabinoid molecule becoming smaller. Consequently, there’s a reduction in weight—accounting for the 12.3% loss. This loss occurs regardless of the efficiency of the activation process.
So, even with Ardent’s high efficiency in converting THCA to THC, the 12.3% loss due to the molecular change still applies. It’s not about looking at it incorrectly; rather, it’s about understanding that these are two separate aspects of the process. The activation rate is about how effectively THCA is converted to THC, while the 12.3% loss accounts for the physical change in the substance.
I hope this clarifies the situation! If you have any more questions, feel free to ask. Happy decarbing!
Hi Emily.
I’ve been making extracts with butter, MCT oil and Everclear, in my slow cooker. I’ve had trouble with maintaining the proper temperature. One night I had an AHA moment that was in my closet. I have a Sous Vide! I can set the temp precisely and can also set the timer. So basically, I can set it up and walk away. If I want it to run 4 hours, I’ll set it for three and a half hours go to bed, go out and forget about it. This is a great alternative to stove top, or slow cooker. Maybe this is on option you could include in your extraction recipes.
Hi there David! I love your AHA moment with the sous vide—what a fantastic tool for making extracts! You’re absolutely right; the precise temperature control it offers is a game changer. I appreciate your suggestion and will definitely consider including it in future extraction recipes. Happy extracting, and thank you for sharing your thoughts! 😊
THANK YOU so much for your cannabutter recipe and calculator.
I am making coconut canna butter. 1:1. One ounce of cannabis (20% THC) to one cup refined coconut oil.
I have shake, not flower. Because The calculator did not ask what type of cannibis I have i am concerned i cant calculate correctly. am using. Should I do TWO oz of
shake for one cup of cannabutter to achieve the same strength? Thank you again.
Hi Gina. Thank you for reaching out and trying our cannabutter recipe and calculator!
Using shake instead of flower is absolutely fine, and it’s great that you’re considering how to adjust the recipe to maintain the desired potency. Generally, shake can be less potent than flower due to the mix of plant material. However, this can vary widely.
For a 1:1 ratio with shake, especially at a 20% THC level for your cannabis, starting with your proposed ratio (1 ounce of shake to 1 cup of coconut oil) is a good starting point. If you’re looking for a potency similar to what you’d achieve with flower, your idea to use two ounces of shake for one cup of oil might bring you closer to your target potency, but it also depends on the quality and specific potency of your shake.
It’s always a bit of trial and error when you’re substituting ingredients, so I’d recommend starting with your initial ratio, testing the potency (safely and responsibly), and adjusting from there in future batches.
I hope this helps. Happy cooking!
How much do I need with 3 grams of wax to my ghee butter
Hi Niki. To determine how much ghee to mix with 3 grams of wax, it usually depends on the desired potency you’re aiming for. You can start with 1g of wax to 1lb of gree and go from there.
