Here you will find the most accurate edible dosage calculator available online to help you guesstimate the potency of your cannabis edibles, recipes, and homemade creations.
Before Using This Calculator
Welcome to my dosage calculator for cannabis edibles and homemade recipes!
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 calculators available online, this calculator hopes to provide more accuracy by accounting for the losses associated with decarboxylation, infusion oils, or extraction solvents used.
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 THC or CBD present in your material
If you have these numbers available, you can get started with the calculator below, the results are shown in pink.
Step 1: Calculate Potency For the Entire Batch
In this first section, you can calculate the potency of your infused product that can later be used directly in your recipe using the second section of this calculator.

JoAnn Praught
Dear Emily,
I made a tincture of 14 g (1/2 oz) 18% thc. How much is a good dosage in tsps for this. I was vaping but now am going to start with edibles. Thank you
I have read your dosing section and still do not completely understand as I am having a hard time feeling anything. I seem to feel best at 2 tsp.
Emily Kyle
Hello JoAnn! Have you considered evaporating any of the alcohol in your tincture? This will help eliminate some of the burn, and it will concentrate your tincture, meaning you will need to take less overall. Here's my evaporation guide to get started. Just keep in mind that your total mg (14x.18x1000=2,520mg) will remain the same, regardless of how much alcohol you evaporate out.
Connie Land
Love your site, and this recipe! It's almost the same one I've been using. Love your exact directions, Thank you!
The only difference is in blooming the gelatin. When I bloom the gelatin, I have so much more volume than if I don't, does blowing matter?
Emily Kyle
Hey Connie, thanks for your kind words; I'm happy you like the gummy recipe. The expanded volume is just fine; in fact, that's exactly what you want! It usually comes out in one solid lump when I add it to the mix 🙂
nicole
hello! i made 1 cup of coconut oil infused with 20g of cannabis. the thc is 22% and it made 150 gummies. how much thc is in each serving? and how much is a serving for 1in gummies?
Emily Kyle
Hi there, Nicole. Did you use the entire 1 cup of coconut oil in the recipe, or just a 1/2 cup as called for? Using the calculator, the total THC in the 1 cup of coconut oil would be 3190.46mg. If you used half a cup that would be 1595.23mg. If you made 150 gummies out of that, you would have 10.63mg per gummy 🙂
Sean
I started this recipe and wouldn't you know it I forgot to decarb in step 1. Well I got to thinking that if I already had the cannabis in a jar with alcohol ( a story for a different post). So what I'm doing is a controlled heating of the jar in water at a steady 200 degrees F and I think I can decarb and reduce the liquid at the same time and then proceed with the other steps. Please tell me I didn't mess up to bad with my first time trying FECO production.
Emily Kyle
Yes Sean, you should be able to achieve decarboxylation at the end. Good luck!
DC
thank you for this calc. it;s very useful for my recipes and for proper dosing for my wife friends and I.
I think it would be even more useful if you could allow decimals in the amounts. For instance, I often get 1.5 cups tincture from my 2 cups batch or maybe 1.25 cups from 1.5 cups, etc.... as some is lost in the biomass.
thanks again
Emily Kyle
Hey DC  thanks for using the calculator! You can absolutely use decimals in the fields for calculations 🙂
Canna MIke
I love your site and that you have the entire family involved. Living the dream. My ? why do you use a teaspoon as a measuring tool.. not sure about other seems so confusing having to covert tsp to a actual amount that any recipe would call for?
Emily Kyle
Hey Canna Mike, thanks so much, we are definitely living the dream. I wanted to break it down to the smallest measurement so it would be easier to calculate single servings. What other measurement mark would you like to see added?
Sherri Brown
Hi Emily, I love the dosage calculator. I wasn’t able to put in a half cup, I was trying to put 1.5 in for my oil amount but it didn't allow fractions. Am I doing anything wrong?
Thank you! I love your site xo
Emily Kyle
Hey Sherri, thanks so much for your kind words. The calculator doesn’t take fractions, but if you put it in as a decimal (either 0.5 or 1.5  depending on what you need) it works 😁
Liezl
Hi Emily! I love this calculator and use it for everything, thank you so much for creating this! I was wondering if you have anything similar to this for honey infusions? I see you have a nice recipe on here, but I was wondering if there was a way to measure the THC contained in honey infusions? Thank you again!
Emily Kyle
Hey Liezl, thank you so much for the kind words. Unfortunately, I do not have an option for honey. In my honey recipe, I currently recommend not straining the kief or ground cannabis out, so you can calculate the total mg of THC just by calculating the potency of the starting material you used. I hope this helps!
Sue Budden
I have a bottle of THC tincture have dropper is .5mg. =3mg. of THC.
How do I measure out the right amount to add to the brownies. What would be my starting point to make brownies. I have never tried too bake with THC, so to say I need help is an understatement. Thank you for your help.
Emily Kyle
Hello Sue! In this case I would work backwards  how many milligrams of THC do you want each brownie to have? If you're new to THC, 5mg is a good place to start. In that case, there are 9 brownies in my recipe. You would need 45mg THC in the total batch (45mg THC/9 brownies= 5mg THC per brownie). If what you're saying is that a halfdropper contains 3mg THC, then you would want to add 15 half droppers, or 7.5 full droppers. I hope this helps 😀
Genice
I am new to this. On average how strong do you wan to make the cannibutter? I have 7 grams, THC 18.64%, CBD 0.05%
My recipe will make 12 servings.
How much butter should I add to the flower in order to use 8 Tbs of butter (24tsp) and have the correct potently. I know everyone’s tolerance is different but on average what do you think?
Emily Kyle
Hey Genice! If you don't know your tolerance, 5mg10mg THC per serving is an excellent place to start. I like to work backward with this. If you want 10mg THC per serving, and your recipe makes 12 servings, you will want 120mg THC in the whole batch. You have flower that is 18.64% THC which means that each gram contains 186.40mg THC. So in this example, adding one gram of flower to the 8 tablespoons of butter will give you slightly more than what you're looking for, about 14mg THC per serving. I hope this helps!
Ken
Hi Emily
Using your calculator just double checking I mixed
16 gram tapioca powder
3 gram CBD oil with 1.3 Mct mixed well
Mixed all together real well then put in bullet mixer
CBD was 800 mg per gram on potency
Your input to my batch much appreciated I now have 16 g of beautiful fine powder with a potency per gram or tablespoon?
Emily Kyle
Hey Ken! Thanks for using the calculator. If I understand you correctly, you have 3 grams of CBD oil with 800mg per gram for a total of 2,400mg CBD in the entire batch. If you want to break it down per gram, it would be 2,400/16 = 150mg CBD per gram. If you want to break it down by teaspoon, you will need to know the total volume and then divide that into 2,400. I hope this helps!
Lisa
Can this be used to determine the amount for milk or cream? I tried plugging in the example numbers you gave in your infused cream recipe but couldn’t get 25mg per serving.
Emily Kyle
Hey Lisa! I apologize, but I don't have an option for milk or cream at this point (they all have different fat contents which would make this super difficult). Since this is just a guestimating tool anyway, I would just pick an oil option and go from there.
James
Emily your recipes are the best especially gummies thank you so much you make it so easy
Emily Kyle
You are so kind, thanks so much for the feedback, James 🙂
Tommy
Hello, Emily. Beginning my journey with edibles and tinctures. I decarbed 28g of flower estimated to be around 15%. Added just enough 190 proof alcohol to just cover the plant material. My plan is to evaporate the alcohol to make feco. From there, I was thinking of adding organic vegetable glycerin to make dosing easier and a bit more palatable. Might even add some berry flavoring, as well. How do I determine the correct amount of glycerin to use in order to keep it potent? THC percentage? I'd like to keep the dosage down to just a few drops instead of teaspoons. Any help and suggestions would be gladly appreciated.
Emily Kyle
Hey Tommy! First, input your values into the calculator and get the final milligrams of THC. For this example, let's say you ended up with 1,000mg of THC. If you added 30mL of vegetable glycerine (the size of a typical bottle of CBD oil, approximately 1 ounce. Perfect if you have a 1mL dropper to use.) You would divide the 1,000/30 and see you get 33.33mg THC per mL. From there, evaluate if that is the correct dose for you. If it's too high, add more glycerine to dilute it out. Too low? Add less glycerine 🙂 I hope this explanation helps!
Trenton R
I have a dinner party coming up and I'm serving jerk chicken for 14 guest. Is 180 mg of Canna oil too much for roughly 14 pieces of chicken?
Emily Kyle
Oh my gosh, that sounds amazing Trenton! 180/14 will give you about 13mg THC per person. If that is the only thing you're infusing for the meal, I think that may be just fine! You could always ask your guests ahead of time if 13mg THC is OK for them.
Adam
Hey Emily!
I’ve been making tincture with 151 proof ever clear. My state doesn’t selling 190 proof. Will that affect the potency? Also I have been buying shake from my dispensary, will that also affect the potency? Thank you!
Emily Kyle
Hey Adam! I don't have lab tests to compare 190 vs 151 proof, but I think you should be just fine  many people use 151. Also, shake may actually be more potent, so hopefully that helps!
