How This Calculator Works
This calculator estimates potency using a few straightforward steps. First, it converts the THC and CBD percentages of your flower into milligrams, since one gram of flower at 1% THC contains about 10 mg of THC.
It then accounts for how efficiently your chosen fat or alcohol absorbs those cannabinoids during infusion, different bases (butter, coconut oil, MCT, alcohol, and so on) pull cannabinoids out of the plant at different rates, which is why the type you select changes the result.
If you check the decarboxylation box, it also factors in the natural loss that happens when raw cannabinoids convert into their active form.
Finally, it divides the total across your batch and then across the number of servings in your recipe, so you get an estimated milligram amount per piece.
Why Your Real Results May Vary
These numbers are careful estimates, not lab results. Real-world potency depends on things this calculator can’t see: the exact cannabinoid content of your specific flower, how thoroughly you decarboxylated, your infusion time and temperature, and how evenly everything is mixed into your final recipe.
Treat the result as a well-informed starting point rather than an exact figure.
How to Find Your THC Percentage
The accuracy of your estimate depends most on one number: the THC percentage you enter.
If you bought your flower from a licensed dispensary, this is usually printed right on the label or package, often shown as “Total THC.” If you’re working with flower that didn’t come with a label, you won’t know the exact figure — but most dried cannabis flower falls somewhere in the range of roughly 10% to 25% THC.
When you’re unsure, it’s reasonable to estimate toward the lower end, since underestimating potency is far easier to adjust for than overestimating it.
One quick measuring tip: your cannabis amount is entered in grams, and there are 28 grams in one ounce — so an eighth of an ounce is about 3.5 grams, and a quarter is about 7 grams.
A Worked Example
Let’s walk through a real batch so you can see how the numbers come together. Imagine you start with an eighth of an ounce of flower (about 3.5 grams) that tests at 15% THC, and you infuse it into 1 cup of coconut oil. You then use that entire batch of infused oil to make a recipe with 48 servings.
Here’s what the calculator does with that: the 3.5 grams at 15% works out to about 525 mg of THC in your flower. After accounting for how efficiently coconut oil absorbs cannabinoids, your finished batch of oil contains roughly 434 mg of THC total. Divide that across 48 servings, and each serving comes out to about 9 mg of THC — which the calculator labels “Mild.”
If you split that same batch into fewer, larger servings, each one would be stronger; into more servings, each would be milder. That’s the whole idea: the number of servings you choose is what sets your dose per piece.
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 account 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.
Everyone is different, and this is general educational information rather than personalized medical advice. The right amount is unique to each person, since we all have endocannabinoid systems that affect our tolerance. 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. Many people choose to start low and go slow, often beginning with the microdosing method — for example, some begin with a small amount such as 1-3 mg of THC and adjust from there. If you are feeling lost, you can also check out my beginner’s guide to using cannabis. If you want 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 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!

Hello. I am infusing a heavy cream coffee creamer (Chobani) with AVB. I heat up the creamer with the avb for about 15 mins at a very low simmer, strain it, and it’s done. Your chart asks what kind of oil or alcohol used. What should I pick that would be as close to a cream as I can get? I am trying to dose it as well as I can.
Also, is my method for infusing the creamer good? If you have any tips or suggestions I would be glad to hear them!
Thank you. 🙂
Hi Tyler! For your infusion, you can select “butter” on the dosage calculator since it’s the closest match to heavy cream. Your method sounds great, but you might want to simmer for a little longer (20-30 minutes) to ensure full infusion. Stir frequently and keep the heat low to avoid curdling. Happy infusing! 😊
Do you have a calculator for using Keiff?
Thank you for your question, Dick! Kief is typically about twice as potent as cannabis flower, so when using the edible dosage calculator, you’ll want to adjust your numbers accordingly. For kief, enter the potency as double the THC percentage of the flower you’re using. This will help you get a more accurate estimate for your dosage. Happy cooking!
Hi in Cannakeys studies for my acute anxiety disorders (ADD and ASD) they point to 300-600 mg / day of CBD. How is it possible to obtain this kind of concentration with infusions at home ?…Or what would be the best way to obtain it. The highest CBD plant materiel I can get so far is 19%ishhh…thanks for your support.
Rico Thib, QC, Canada
Hi Rico, thanks for your question! If you’re looking to achieve higher CBD concentrations at home, I recommend checking out this guide on making Full Extract Cannabis Oil (FECO): https://emilykylenutrition.com/full-extract-cannabis-oil-feco/. It’s a great resource for creating potent, concentrated medicine using your own plant material. Hope this helps!
I made 27 chocolate chip cookies using 1/2 cup of infused butter what is the potency of each cookie %of THC is 26
Hi Connie,
To determine the potency, start by calculating the total THC in the infused butter. If the flower contains 26% THC, that translates to 260 mg of THC per gram of flower. Simply multiply the total grams of flower used in your butter by 260, then divide the result by 27 to est The Most Accurate Edible Dosage & Potency Calculatorimate the approximate THC content per cookie.
For a more precise calculation, try our online calculator. It accounts for factors like infusion efficiency and decarboxylation loss, giving you a more accurate breakdown.
We make whole flower plant matter capsules and have been for the last 5 years. The calculator we used is no longer available. We make 10mg capsules with different strains of decarbed flower, but they are all 10mg. We buy from a dispensary with the total THC and other cabinoids already measured, But we are trying to find calculator for this purpose of making the capsules. Do you have one for this purpose or do you have a formula? Thank you in advance.
Thank you for your question, Adriana! Here’s a simple formula to help you calculate the potency of your capsules:
Start with the total THC percentage listed on the dispensary label. For example, if the flower has 20% THC, it means there are 200mg of THC per gram of flower (since 1g = 1000mg and 20% of 1000 is 200mg).
Account for the decarboxylation process, which typically results in about a 12% loss of THC. To adjust for this, multiply the total THC by 0.88 (for a 12% loss). Using the previous example:
200mg of THC x 0.88 = 176mg of THC per gram after decarboxylation.
Divide the total THC amount by the number of capsules you want to make. For a 10mg capsule, divide the total THC by 10 to figure out how many capsules you can make per gram. In this case:
176mg ÷ 10mg = 17.6 capsules per gram of decarbed flower.
If you’re working with a larger batch, you can scale the numbers accordingly (e.g., if you’re using 5g of flower, multiply 170mg by 5 and then divide by 10mg/capsule).
Hope this helps, and happy capsule-making!
What about using honey as a carrier? I did not see that on the drop down list.
Hi Dan. When infusing honey with cannabis, you add the cannabis directly to the honey without straining. This allows the honey to retain the full potency of the cannabis. If you know the strength of what you are adding, you can then divide by the number of servings, to determine the potency of each serving. I hope this helps!
I plan on making infused brownies soon. Just so I’m clear, if my recipe uses 1 cup butter I just use 1 cup of infused butter in its place. Correct?
I’m so happy to hear you’re planning on making infused brownies, Dan! 😊 Yes, you’re correct—in your recipe, you can replace 1 cup of regular butter with 1 cup of your infused butter. Just make sure your dosage strength is where you want it to be for a delicious and enjoyable experience.
I don’t understand the last portion of the Potency Calculator. I don’t understand “teaspoons used”. My batch makes 44 – 1 teaspoon servings. The TCH is 28.725, CBD 0, used 28 grams, 1 cup of grain alcohol for 30 days. What should the sum of these numbers be?
Hello Jo 😊 When it comes to the “teaspoons used,” you can think of it as part of breaking down the serving size if needed. Since your batch creates 44 servings, focus on that number. The calculator helps you determine how much THC each of those servings contains. If the total THC of your batch is 6695.19mg and you have 44 servings, divide the total THC by 44 to get the potency per teaspoon serving. I hope this helps clarify!
I make 30 day soak everclear tincture. According to your calculator, thc loss between decarbing and loss from solvent soak is approx 16%?
Hey Richard, while decarbing typically results in a minor loss, the prolonged soaking can lead to further loss over time, especially if left beyond the recommended period. It’s always key to balance soaking time to achieve desired potency while minimizing loss 🙂
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
Hi Roberta, We’re so happy that the calculator is making it easier for you to manage portions and enjoy your creations without worry! It’s great that you’re considering the different tolerance levels of your friends and family too. Making gummy bears sounds like a fun next step! If you have any questions or need tips, feel free to reach out. Enjoy your baking adventures!
Thank you so much for not only calculator, but all the knowledge you pass on.
You’re very welcome, Rashima! We’re thrilled that you find the calculator and the knowledge shared valuable. If you have any questions or need further clarification on anything, feel free to ask. Happy learning!
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 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
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.
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!
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 😭
