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.
Features
 Use this to estimate the potency of homemade edibles
 A calculator that includes the loss associated with decarboxylation
 A calculator that takes into account your infusion or extraction material
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 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 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.
Starting Amount of Cannabis Product in Grams 

THC/THCA % 

CBD/CBDA% 

Type of Oil or Alchol Used 

Amount of Oil or Alcohol Used in Cups 

Account for the loss associated with Decarboxylation?Check this box if you decarbed your product and want to account for the natural loss associated with the process.

Frequently Asked Questions
Great question! If you have done the math above but still feel unsure where to start, check out my guide to dosing edibles safely and effectively. If you are feeling very lost, you can also check out my beginner's guide to using cannabis.
The calculator has been updated since November 9th, 2022, to fix the disappearing decimal issue. If you notice any trouble, please leave a comment below.
If your concentrate already comes with a milligram dosage on the label, you do not need to use this calculator. Simply divide the total milligrams of THC by the number of 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.

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!
Costanza
This calculator just might have saved me a really rough night. I wanted to make my pain creme a little stronger and then use the rest of the coconut oil to make brownies. I used 30grams of flower that was about 15% thc and I am glad I used this calculator so I can now cut them into 24 pieces, 12 pieces per batch might have put me in a coma.
Emily Kyle
I am so glad to hear this calculator helped save you, Costanza!
shirkhan
Hi Emily,
I really liked your website and the calculator, it is very helpful.
I smoke regularly for 10 years about 0.16 grams a day.
I was told that you have to multiply by 4 the amount you smoke to know the amount of weed you put in a brownie.
is it true? Because according to the calculation I wrote later, it sounds like it's a lot.
I want to make brownies for the first time for me and my friends (we all smoke regularly).
I'm trying to figure out how many grams to put for 9 people.
Our cannabis 0.1 >CBD
THC 24.3%
If I use 2 grams and make 9 brownies according to the calculation, I got 420 mg of THC
Divide into 9 brownies, this is 46 mg per piece.
Is 46 mg too much for one person?
10 mg sounds too little to us for a brownie, maybe we'll make 20 brownies from the 2 grams and if we need it after two hours and feel it's weak we'll eat another piece.
I'd be glad to hear your opinion 🙂
Emily Kyle
Hey Shirkhan, thanks so much! I've actually never heard that before; this is new to me. From everything I understand, your tolerance for smoking has no correlation for your tolerance for edibles. This is because when you smoke, your body is processing THC, but when you consume edibles, your liver is converting THC into 11OHTHC, which is a totally different animal. All bodies convert differently because of our unique digestive systems, digestive enzymes, and endocannabinoid systems. So my recommendation for ALL consumers is always to start low, with 510mg to start. This will allow you to gauge how you feel, without over consuming. Not saying that 46mg may not be a perfect place for you eventually, but it could be too much, and you don't want to feel unwell by accidentally overconsuming. I hope this helps!
Jburnz
Hi when calculating CBG do input that into the CBD section or THC section of the calculator.
Thanks,
JB.
Emily Kyle
Jburnz, you can use either one 😀
Karina
Hi Emily,
I am completely new to making my own edibles. I just did a trial run without any THC with your recipe I made 48 pieces that were about 1 teaspoon each and 48 that were about 2 teaspoons. I’ve read this and tried using the calculator but I am still confused. I am having a hard time figuring out how much flower to use to infuse my coconut oil. Ideally I would like them on the stronger side 1525mg each. What do you recommend?
Emily Kyle
Hey Karina. If you have 48 pieces and you want them (average) 20mg each, you'll need 960mg THC to start (48x20=960). Next, you will need to know the % THC in you're starting material. If you don't know that, an average number I will use for this example is 15% THC. At 15% THC, you will get 150mg THC per gram, so you will need 6.4 grams of flower (960/150) to get to your desired amount of 960mg THC total. I hope this makes sense!
bob from ohio
you stated to commenter "DC" on June 22, 2022 that you could use decimals with the online calculator but when you input a decimal the calculator backspaces it out  you cannot use decimals  this would be a great addition to this already great tool
Emily Kyle
Hey Bob! Thanks so much for bringing this to my attention. It looks like it's a browser compatibility issue with Chrome. I have the tech team working on the issue, but in the meantime, you can successfully use the decimal function on Safari 🙂
Emily Kyle
Hey Dom, luckily, they give you the answer on the package; the 1mL syringe contains 866mg of THC. If you wanted chocolates at 20mg of THC, say a teaspoon each, you would need to melt the entire syringe into approximately 43 teaspoons of melted chocolate (866/20=43.3). This would be about 1 cup of melted chocolate. I hope this helps!
Dom
I tried to use the edibles dose calculator but I'm not sure how to use it the concentrate I have. I was going to try your chocolate recipe. I would love to know how to make it so each piece chocolate has about 20mg THC in it.

Emma
Hi Emily,
First I would like to thank you for creating this space and offering guidance. Your dosing calculator is very helpful. Is the "number of teaspoon used in your recipe" the number of butter used?
Emily Kyle
Hey Emma, thanks so much for your kind words and thank you for being a part of this space. Yes, the "number of teaspoons" would be the amount of butter used in a recipe, like cookies or brownies for example. If you used 1/2 cup of that cannabutter in a recipe, that would be 24 teaspoons. I hope this helps 😀
Chrissy
Hello! This is my first attempt at making FECO. The strain I am using has 22% THC, 0.026% CBD. I'd like to start with 1/2 cup of Everclear to 0.5 grams of cannabis flower. Would that yield 4.17 mg per serving (teaspoon)?
Emily Kyle
Hey Chrissy! When I input these values into the, I got: 3.82mg of THC per teaspoon 🙂 I checked the box to account for the loss associated with decarboxylation.
John
I used the instant pot to infuse coconut oil. Worked great can I infuse 58 grams of canabis into one cup of oil to make it more potent?
Emily Kyle
Hey John, if you can get the oil to cover the plant matter completely, you should be good to go 😀
Anita
How much alcohol mixture do I need for 10 pounds sugar
Emily Kyle
Hey Anita, you will need to do the math and determine how strong you want your final product first. Then put that amount of cannabis into the tincture before making the sugar.
Emily Kyle
Hey Alli. In most cases, you don't need to use this calculator for RSO (unless you're making it yourself). Are you purchasing the RSO? Does it come with a total mg on the package? If so, you simply need to divide that number by your total number of servings to get a final dosage.
Alli ReauVeau
Hi, could you make this RSO friendly? I use 1 teaspoon 1G. I get 60 capsules at 80.16 THC. This calculator is the best but tiny batch not so good. I’d really like to keep using this but it doesn’t work for 1 teaspoon 😟
Susan
I am using ground cannabis and melted chocolate. How do I figure dosage? 7 grams cannabis at 13.33%thc my chocolate bar mold is five bars of 12 pieces each. I made 5.5 bars.
Emily Kyle
Hey Susan, you can input the 7 grams and 13.33% THC in the calculator = 933mg THC. For your servings, simple multiple 12x5.5= 66 total servings. Then divide 933mg THC / 66 servings = 28.3mg THC per serving. I hope this helps!
Ed
Just picked up some keif from the dispensary and I want to make some cannabutter. It's 4 grams, 45.17 THC, .17 CBD
How long and what temperature for decarboxylation ?
I thinking a pound of butter ?
Emily Kyle
Hello Ed! I have a full guide for how to decarb kief here and other guide for how to make kief butter here. I hope this helps!
RJ
I’ve used your dosage calculator for about a year now. I used to be able to use decimals. Since September, I cannot use decimals. I had some friends try too and they are unable to use a decimal too. We’ve done everything my IT guy said to do and it is still not letting the use of decimals. He said to contact you. Thank you for your time. Your website is the best!
Emily Kyle
Hello RJ  I apologize for the inconvenience! Our tech team is currently working to fix this, and I hope it will be resolved soon 🤞
Philip
Hello Emily,
Great site and the cannabutter then cookies I made we wonderful. I do have a question, I start with a cup of butter before the infusion process. After straining I have 6.5 ozs left, where does it all go?
Thank You
PG
Emily Kyle
Hello Philip, thanks so much for the kind words, I am so glad your cannabutter and cookies turned out good 😀 Great question; it goes two places. First, when making cannabutter, water and milk solids in the butter are evaporated and removed, which can account for up to a 20% loss in volume. Second, the flower can soak up a lot of the liquid, so depending on how tightly you strain, it may be caught up in the leftover pulp. Starting with clarified butter will help avoid this!
I also see you are already a member of my private Well With Cannabis Community, feel free to share this comment there as well to see if you get more responses from the other members 🙂
Jordan
Why would you need to check the box for decarboxylation loss? The THC percentage of your flower has already been calculated by accounting for this loss (THCa x 0.877 + THC). So if you input this THC number and check the decarb box, you are essentially accounting for decarboxylation twice. It only makes sense to check the box if you’re inputing THCa percentage of the flower.
Also, how did you determine the loss of THC for each infusion liquid?
Thanks
Emily Kyle
Hi Jordan. Our next update will include language to read as THCA/THC for users to select the option they need. Not everyone uses products purchased from a dispensary that automatically accounts for that conversion, so the option is best left to the user.
Kelly
Hi. If I want to make cookies that calls for one stick of butter. Would I use all of the cannabutter or would I only substitute a few teaspoons in the recipe?
Emily Kyle
Hey Kelly. That is totally up to you and how strong you want each cookie to be. If you want it super strong, use the whole stick, and if you want it less potent, you can use just a few teaspoons or tablespoons. If you're unsure about individual dosing, this dosing guide may help!
taiga
Hey Emily,
I've been here to use this calculator many times now and just wanted to say thank you for putting together such a useful tool.
Emily Kyle
Hello Taiga, thank you so much for the kind words, I am so glad you're enjoying the calculator 😀
John
I’m trying to calculate the dosage content and the calculator doesn’t seem to be working for me. I’m sure I’m doing something wrong but here are the details:
I used 21 g of flower to make four sticks of butter. But only used two clicks in the recipe. So I’m thinking that would be 10.5 g used.
The flower is 27% THC content and 1% CBD content.
I used two sticks of butter, or one cup.
It yielded 63 mini brownies. The batter was about 1.5 teaspoons each.
When I enter these numbers it says each portion has a THC con tent of 89, which does not sound right at all. What am I doing wrong?
Emily Kyle
Hey John. When I put in 10.5 grams of flower at 27% THC content with 1 cup of butter, without accounting for decarboxylation of infusion loss, I get 2835mg THC. Which is accurate with the math. 27% THC of 1 gram = 270mg THC. 270x10.5 = 2835. If you click to add in the loss for decarb and infusion you get 2209 mg THC. From there, you divide that by 63 for your total servings which leaves you with 35mg THC per minibrownie. I hope this helps!
Brenda
In the following field TOTAL MG OF THC PER TEASPOON
35.72
Would the teaspoon refer to the tincture ( 190 proof) or a teaspoon of the FECO?
Emily Kyle
Hello Brenda! That would be for a teaspoon of the tincture. If you evaporate off all of the alcohol, the "total mg of THC" line will reflect what is in your FECO. I hope this helps!
Jay L
LOVE the site/calculator! As a newcomer to making my own edibles, this is such a great site because you break everything down in simple terms...I have a curveball for you though, I just can't wrap my noob head around figuring out ANY approximation for my dosing!
As a noob, Google has been my friend. I made coconut infused oil (450mL) using trim from a ~20%THC harvest, recovered as waste after 2 rounds of bubble hash making (cold water extraction) as Google said the trim is still suitable for edibles.
After drying and decarboxylating the waste, I had a starting weight of 58g.
Any thoughts on how I'd approach this 58g of keifed trim in 450mL oil from a dosing standpoint? Google mentioned the waste is less potent as starting material hence the high ratio of weight to oil...sorry for the extended typing lol. I'm just so confused
Emily Kyle
Hey Jay! Thanks so much for you kind words. Unfortunately, there is literally no way to calculate an approximate dose at this point. The best option, depending on how bad you really want to know, would be to send it to a lab for testing. Potency samples run about $60. Otherwise, it truly is just a wild guess.
Torsten Wigforss
I have question about using the calculator for determining dosage when wanting to use just decarbed cannabis i.e. a firecracker.
Using 10 gm of cannabis at a 20% strength, and no oil or alcohol used, I get a total of 1754 mg of THC (after accounting for the loss during decarboxylation.) This would be 175.4 mg per gram of cannabis, which seems awfully high.
Given that you suggest on the firecracker recipe page starting with 1/4 teaspoon (which is about 1 gm), this seems to be way too much. What am I missing? Thanks!
Emily Kyle
Hey Torsten! You're not missing anything, you are completely correct with your math. I'm going to adjust the firecracker recipe to call for less, because yes, that is super potent for some people 😀 Thanks for pointing that out!
Lauren
Thank you for all of the work you put into this calculator and all of your articles! If I’m infusing milk, should I click “no solvent?” Thanks again!
Emily Kyle
Hello Lauren! If it's a full fat milk, I would choose butter or oil as the solvent used! I will look into adding a milk option in the future 😀
ASTRID JORDANA BYRO
Could you please do a metric version? I’m happy to help if needed
Emily Kyle
Hello Astrid! Thank you for the request, we will work on this for the 2023 season 😀
Lori
Can I substitute
E more canna butter instead of water as my gummies aren’t very potent
Emily Kyle
Hello Lori! I haven't tried myself, but I would be inclined to say no, you really need the water to bloom the gelatin. Would it be possible to work to make your cannabutter more potent, instead?
