edible dosing calculator

Calculate the precise THC and CBD potency of your homemade infusions and edibles in seconds.

What is an Edible Dosing Calculator?

An Edible Dosing Calculator is a specialized tool designed to help home enthusiasts and professional chefs determine the specific potency of cannabis-infused products. Whether you are making cannabutter, infused oils, or tinctures, knowing the exact milligram count of cannabinoids (like THC or CBD) in each serving is critical for safety and consistency.

Using an Edible Dosing Calculator allows you to account for various factors that affect the final strength, including the weight of the raw material, the lab-tested potency of the plant, and the efficiency of the infusion process. Many beginners underestimate how strong a homemade batch can be; this tool eliminates the guesswork, ensuring a predictable experience every time.

Common misconceptions include the idea that all cannabinoids transfer 100% into the fat or that the weight of the flower equals the potency. In reality, chemical processes like decarboxylation and physical limitations of solvents create a loss of potential, which our Edible Dosing Calculator helps you quantify.

Edible Dosing Calculator Formula and Mathematical Explanation

The math behind cannabis infusion is a multi-step process. To reach an accurate dose, we must convert grams to milligrams, account for the loss of the carboxyl group during heating (decarboxylation), and estimate the loss of material during the straining and binding process.

Variable	Meaning	Unit	Typical Range
Weight (W)	Amount of dry flower used	Grams	1g – 30g+
Potency (P)	Percentage of THC/CBD in flower	%	10% – 30%
Decarb Factor (D)	Efficiency of THCA to THC conversion	Constant	0.88
Efficiency (E)	Solvent extraction percentage	%	70% – 90%
Servings (S)	Number of final individual portions	Count	1 – 100

The core mathematical formula used by our Edible Dosing Calculator is:

Dose per Serving = ((Weight × 1000) × (Potency / 100) × 0.88 × (Efficiency / 100)) / Servings

Practical Examples (Real-World Use Cases)

Example 1: The Standard Brownie Batch

Imagine you have 7 grams (a quarter ounce) of flower that is tested at 20% THC. You plan to make 24 brownies. Using an infusion efficiency of 80% (common for butter infusions):

• Inputs: 7g flower, 20% potency, 80% efficiency, 24 servings.
• Calculations: 7,000mg total flower weight × 0.20 = 1,400mg raw THC. Adjusted for decarb (1,400 × 0.88) = 1,232mg potential. Adjusted for efficiency (1,232 × 0.80) = 985.6mg final batch.
• Result: 985.6mg / 24 servings = 41.07mg per brownie.

Example 2: High-Potency CBD Tincture

You use 14 grams of high-CBD hemp (15% CBD) to make a tincture. You want to divide this into 60 doses (2 ounces of liquid, 1ml per dose).

• Inputs: 14g flower, 15% potency, 75% efficiency (alcohol-based), 60 servings.
• Result: Approx 1,848mg total potential CBD, resulting in 1,386mg infused. 23.1mg per serving.

How to Use This Edible Dosing Calculator

1. Enter Flower Weight: Weigh your dried herb accurately using a digital scale.
2. Input Potency: Look at the packaging from the dispensary for the THC/CBD percentage. If homegrown, estimate based on strain averages (usually 15-20%).
3. Estimate Efficiency: If you are using a dedicated infusion machine, use 85%. For stovetop methods with good straining, use 75-80%.
4. Define Servings: This is the total number of pieces you will cut your batch into, or the number of droppers in a tincture.
5. Interpret Results: The Edible Dosing Calculator will instantly show the mg per serving. Compare this to your tolerance level.

Key Factors That Affect Edible Potency Results

• Decarboxylation Quality: If you don't heat your cannabis at the right temperature (approx 240°F) for the right time, the THCA won't convert to THC, resulting in a much weaker product.
• Solvent Type: Fats like clarified butter (ghee) or coconut oil bind better to cannabinoids than lower-fat alternatives.
• Straining Technique: Squeezing your cheesecloth or filter too hard can add plant matter, while not squeezing enough leaves potent oil behind in the "sludge."
• Temperature Stability: Overheating during infusion (above 300°F) can actually degrade the THC into CBN, which is more sedative and less psychoactive.
• Surface Area: Grinding your flower too fine makes it hard to strain, but too coarse reduces the surface area for the fat to bind to.
• Bioavailability: How your body processes the edible depends on whether you've eaten recently and your personal metabolism.

Frequently Asked Questions (FAQ)

Why does the Edible Dosing Calculator use a 0.88 multiplier?

When THCA is heated, it loses a carboxyl group (carbon dioxide). This molecular change reduces the weight of the molecule by approximately 12%, meaning you only get 88% of the original potential weight in active THC.

What is a safe starting dose for beginners?

Most experts suggest starting with 2.5mg to 5mg of THC. Use the Edible Dosing Calculator to ensure your recipe stays within these bounds.

Can I use this for CBD oil?

Yes, the math for CBD is identical to THC. Simply enter the CBD percentage in the potency field.

How do I know the efficiency of my butter?

Home stovetop infusions usually range from 70-80%. Professional infusion machines can reach 90%+. If you are unsure, 75% is a safe "average" estimate.

Does grinding the flower change the potency?

Grinding increases surface area which can help efficiency, but it doesn't change the amount of THC physically present in the plant material.

Why do my homemade edibles feel stronger than dispensary ones?

This is often due to the "entourage effect" of full-spectrum infusions compared to edibles made with pure THC distillate. Also, dosing errors are common without using an Edible Dosing Calculator.

Does the type of oil change the dose?

Saturated fats (coconut oil, butter) are better carriers for THC, potentially increasing the efficiency percentage you should enter into the calculator.

What if I use "Already Vaped Bud" (AVB)?

AVB is much weaker, usually around 3-5% THC. You can still use the Edible Dosing Calculator, just lower the potency input significantly.
