How strong is homemade THC or CBD oil if I use "X" grams of flower and "X" cups of oil? Calculator works for isolate and all cannabinoids. This printable cannabis flower to oil ratio guide will help you decide how much to use so you end up with a perfectly potent product.
CBD THC Oil Potency Calculator – For Homemade Oil or Recipes
How much THC, CBD, or other cannabinoids are in your homemade oil? I made this useful calculator to help you figure that out.
As someone who wants to make their own CBD or THC oil at home, this is a critical question. You need to know how many milligrams of CBD are in each milliliter of oil.

Steps for using the CBD THC Potency Calculator:
The calculator is very simple. Follow the steps below to determine how potent your cannabinoid oil infusion will be. In order to use the calculator you need to know what percent cannabinoid your flower is.
Step 1: Figure out Total CBD or Total THC Percentage
CBD and THC start out in flower as CBDa and THCa. When you decarboyxlate (add heat) it changes to to CBD and THC, respectively, at a maximum rate of 87.8%. In other words roughly 12% of the cannabinoid in the flower is destroyed when it converts.
So when you’re trying to determine the total amount of CBD or THC in your flower, you need to take the percentage of CBD or THC and multiply it by 0.878 to account for the 12% lost during decarboxylation. That’s the number you should enter into the calculator above.
Your vendor might have given you a lab test with your flower. The lab test should show the level of CBDa, CBD, and a total CBD number (CBDa + CBD). Type the total CBD number in the calculator above.
If you don’t have a lab report, you can simply multiply CBDa percentage by 0.878, then add that number to any existing percentage of CBD to arrive at the total amount of CBD.
Most lab results will provide each number for you (CBDa, CBD, Total CBD) and you want to use the Total CBD/THC number for the calculator above.
Step 2: Put percentage number into form
Type the total amount of CBD flower, or amount of isolate, in grams, that you plan to use. If you’re using isolate you may be using less than one gram. To type a milligram amount, simply use a decimal number. 1 milligram should be typed as 0.001. 500 milligrams should be typed as 0.5
Step 3: Type amount of oil to be used into form
Type how many cups of oil you’re considering infusing the CBD into.
On the bottom of the calculator you will see the total milligram amount of CBD that will be present in your entire oil infusion, if you choose to use the amounts typed in Steps 1-3.
If you want a weaker or stronger oil infusion, you have a few options:
- Use CBD flower with lower or higher CBD content, depending whether you want lower or higher cannabinoid concentration in your oil infusion.
- Use more or less quantity of CBD flower, or use more or less isolate, depending whether you want lower or higher cannabinoid concentration in your oil infusion.
- Use more or less oil. Using more oil without adding additional flower or isolate will weaken the potency. Using less oil without changing the amount of flower or isolate will make your oil infusion more potent.
- There are limits to how much you can infuse into a certain amount of oil. I don’t know the limit but I know from experience only so much decarbed flower will fit into 1 cup of oil for infusion.
Complete all steps listed in first part of calculator, described above.
Look at the potency per teaspoon and type in how many teaspoons of oil you’ll use for your entire recipe. Then type in how many servings are in your entire recipe, and you’ll see how potent each serving will be.

Why You Will Love This Guide
Edibles are a great way to consume cannabis to find relief from unwanted symptoms, but if you’re buying them from a dispensary, the costs can add up.
That’s why so many of my Well With Cannabis Community members love to save money by making edibles at home.
This can be done with a simple infusion of cannabis flower and fat like butter, coconut oil, or olive oil.
But the same question is always asked, how much cannabis and oil should I use?
It’s a great question because how much of each you decide to use will impact the potency of your final product.
This guide will discuss how you can determine the perfect flower-to-oil ratio for your infusion so you can get your chill on and save money simultaneously!
How to Use The Ratio Chart
The easy-to-use chart above will help you decide how much flower and oil to use based on how big you want your final batch to be.
This works for infusions that are made in a crockpot, Instant pot, or even an infusion machine, depending on the capacity it can hold.
The chart has two parts, a 1:2 ratio (1 ounce to 2 cups) and a 1:1 ratio (1 ounce to 1 cup).
But which chart should you use?
One of the best parts about making cannabis infusions is that you can make them as strong or mild as you prefer.
If you have a low tolerance or are looking for a mild dose, you should use the 1:2 ratio chart listed first.
If you have a high tolerance or are looking for a stronger dose, you can reference the second chart and use a 1:1 ratio.
For a 1:1 example, one ounce of decarboxylated flower will be mixed with one cup of butter.
This will create an infusion twice as potent as if you were to use the 1:2 ratio.
When deciding which ratio to pick, consider your tolerance, and if you’re new to edibles, be sure to follow the golden rule of “start low and go slow.”
Other Factors to Consider
As a general rule, it’s essential to know that the more cannabis flower you add to your infusion, the more potent your edibles will be.
You can also increase the potency by decreasing the amount of oil or butter to get the same effect.
My flower-to-oil ratio chart above breaks it down so you can easily and accurately mix the right amounts – but there are a few other factors to consider as well.
The Potency Of The Flower
While the amount of flower and oil you use matters, so does the potency of the flower you’re using.
Cannabis flowers can contain anywhere between 0-30% cannabinoids or the important compounds we want like CBD, CBG, and THC.
Different strains can have different percentages of cannabinoids. Without lab testing, it is impossible to know this exact number.
If you purchased cannabis from a dispensary, it should come with a lab report or printed number stating the total percent of cannabinoids in the product.
If you grew your flower and know the strain you used, online resources like Leafly should be able to give you an average percentage of what the strain typically produces.
Remember, the higher the percentage of cannabinoids, the more potent the final infusion will be.
If You’re Working With Trim
The chart above is was designed with the thought that you would be using traditional cannabis flower buds.
But what if you want to make an infusion with trim or shake?
If you’re working with trim, I typically recommend you double the amount of “flower” in the cart.
This is because trim, like fan leaves or sugar leaves, is typically less potent than flowers, so doubling up on the amount will help keep the potency higher.
Of course, this is just a rough guesstimate, and will again depend on the strength of the flower and your personal tolerance.
If You’re Working With Kief
Again, the chart above is was designed for using cannabis flower buds.
However, if you’re lucky enough to have collected a nice amount of kief, you can easily infuse it into butter or oil.
If you’re working with kief, I typically recommend you *at least* halve the amount of “flower” in the cart.
This is because kief has the potential to be anywhere between 50-70% more potent than traditional cannabis flower due to its high trichome content.
Take care when preparing a kief oil or kief butter, as they can be very potent depending on how they are made.
A Calculator Can Help
While it is no substitute for lab testing, an online calculator can help you determine the potency of your final product.
For this to work, you will need to know the potency of the material you are working with or at least have a general idea.
You can input values into my edibles dosage calculator and see the final potency before infusing.
Get To Know Your Tolerance
By changing the amount of flower to oil in your recipe, you can manipulate the final product to be as potent as you’d like.
The more flower you use, the more potent it will be. The more oil you use, the more you will dilute the infusion.
Since cannabis affects everyone differently and the endocannabinoid system is highly individualized from person to person, it’s essential to know your tolerance level.
Cannabis enthusiasts agree that the best way to consume THC edibles safely is to “start low and go slow.”
That way, you are less likely to experience the unpleasant side effects of too much THC consumption, like anxiety and paranoia.
It’s always advised to start with a low flower-to-oil ratio for your first batch of edibles and see whether it meets your needs.
If it’s not as potent as you’d like, you can try a stronger ratio next time.
To find the perfect ratio for your tolerance level, keep experimenting with different amounts of cannabis flower and oil.
Once you’ve got the right potency, you’ll be able to make all kinds of edible recipes at home on your own.
Traditionally, cannabis brownies are a fan favorite, but you can make anything from cookies and candies to no-bake edibles and more with your infusions.
Whether you’re just beginning your journey into homemade cannabis-infused treats, or if you’re a seasoned baker, this flower-to-oil ratio chart will help as a quick guide.
