About This Calculation

This calculator estimates THC per serving based on the weight and potency of your cannabis, minus potency lost in processing. Always dose carefully and label homemade products.

Cannabis-infused products such as edibles, tinctures, and oils are becoming increasingly popular among both recreational and medicinal users. One of the biggest challenges when making cannabis products at home is determining the correct dosage. Too little THC may make the product ineffective, while too much can cause overwhelming effects. This is where a THC Potency Calculator becomes an invaluable tool.

Our THC Potency Calculator helps you estimate how much THC is in each serving of your homemade cannabis product. By simply entering the cannabis weight, THC percentage, product yield, and estimated loss during processing, you can quickly determine the potency of your final product. This ensures safer, more consistent, and more enjoyable results.


How to Use the THC Potency Calculator (Step by Step)

Using this calculator is straightforward. Follow these steps to get accurate results:

  1. Enter Cannabis Weight (grams):
    Input the amount of cannabis you are using in grams. For example, 5 grams.
  2. Input THC Percentage (%):
    Enter the THC percentage of your strain. If your cannabis is 18% THC, type in 18.
  3. Enter Final Product Yield (grams):
    Provide the total weight of your final product or serving size. For example, if you make brownies weighing 100 grams in total, enter 100.
  4. Account for THC Loss During Processing (%):
    Since not all THC survives cooking or extraction, the calculator includes an option for THC loss. A default of 20% loss is common.
  5. Select Product Type:
    Choose from edibles, tinctures, oils, or other product types to categorize your calculation.
  6. Click “Calculate”:
    The tool processes your inputs and shows:
    • THC per serving (mg)
    • Total THC used (mg)
    • THC after loss (mg)
    • Number of servings
    • Selected product type
  7. Reset or Share Results:
    Use the reset button to start fresh or share/copy your results directly.

Practical Example: Calculating THC Potency in Brownies

Imagine you’re making cannabis brownies and want to know the potency per serving.

  • Cannabis Weight: 7 grams
  • THC Percentage: 20%
  • Final Product Yield: 14 servings (about 14 grams each)
  • THC Loss During Processing: 20%

Step 1: Total THC Used

7 grams × 20% THC × 1000 = 1400 mg THC

Step 2: THC After Processing Loss

1400 mg × (100 – 20)% = 1120 mg THC

Step 3: THC Per Serving

1120 mg ÷ 14 servings = 80 mg THC per serving

Result: Each brownie contains approximately 80 mg of THC. For most users, this is a very strong dose, so you might choose to cut them into smaller pieces for safety.

Helpful Tips for Using the Calculator

  • Always know the THC percentage of your cannabis strain (lab-tested results are best).
  • Remember that THC loss varies depending on cooking or extraction methods.
  • Start with small doses when trying new products, even if the calculator shows potency.
  • Properly label homemade edibles or tinctures with dosage information.
  • Consider tolerance levels—what’s strong for one person may be weak for another.

Frequently Asked Questions (FAQs)

1. What is a THC Potency Calculator?

It’s a tool that estimates the amount of THC per serving in homemade cannabis products like edibles, tinctures, or oils.

2. Why do I need to calculate THC potency?

Accurate dosing ensures safety, consistency, and effectiveness of your cannabis-infused products.

3. How accurate is this calculator?

It provides a close estimate, but actual results may vary due to factors like cooking methods and cannabinoid loss.

4. What does “THC loss during processing” mean?

It refers to THC that degrades or is lost during cooking, decarboxylation, or infusion. A 20–30% loss is common.

5. How do I find the THC percentage of my cannabis?

Check lab test results from your dispensary or look up the average THC content of your strain.

6. Can this calculator be used for CBD products?

Yes, the same formula applies if you replace THC percentage with CBD percentage.

7. What serving size should I enter?

Enter the total final product weight or portion size (e.g., total brownie weight or gummy count).

8. How much THC is considered a standard dose?

For beginners, 2.5–5 mg THC per serving is common. Experienced users may prefer 10–20 mg.

9. What happens if my calculation shows high THC per serving?

You can divide the product into smaller portions to lower the dose per serving.

10. Does decarboxylation affect potency?

Yes, THC must be activated through decarboxylation (heating). If skipped, potency will be lower.

11. Can this calculator work for cannabis oils and tinctures?

Absolutely, just enter the cannabis weight, THC%, yield, and loss to find potency per dropper or milliliter.

12. How much THC is usually lost during cooking?

Typically between 20–30%, depending on temperature and cooking time.

13. Can I rely on this tool for medical cannabis dosing?

It’s a helpful guide, but consult with a medical professional for precise medical dosing.

14. What if I don’t know the THC percentage?

Use an estimated average for your strain (e.g., 15–20%), but results will be less accurate.

15. Is it safe to consume high-THC edibles?

High doses may cause anxiety, paranoia, or discomfort. Start low and increase gradually.

16. How do I reduce potency if my edible is too strong?

Cut portions smaller or mix with non-infused ingredients to dilute THC concentration.

17. Can this calculator be used for microdosing?

Yes, it helps calculate very small, controlled doses for microdosing purposes.

18. Does this work with concentrates like hash or wax?

Yes, if you know the THC percentage, you can calculate potency the same way.

19. Can I save or share my results?

Yes, the tool includes options to copy or share your THC potency results instantly.

20. Is there a risk of overestimating or underestimating potency?

Yes, slight variations may occur due to strain variability and preparation methods, so always start with a small dose.
