Edible Dosage Calculator
Step 1: Infuse Butter or Oil
🍳 Cooking Potency Loss
THC degrades during cooking. Select your settings for accurate dosing.
Step 2: Calculate Recipe Potency
Easily calculate the potency of your homemade edibles in just a few seconds with The HighWay’s handy Edible Dosage Calculator.
Cannabutter or Infused Oil:
- Input the THC and CBD percentage of your flower. If you don’t know, then 20% THC is always a safe assumption. If you want to be even more careful, then assume 25%. For CBD, use 0-1% if you do not know.
- Input the weight of the flower in grams. You can always eyeball it, but it’s much safer to use a scale. We would recommend this Nicewell Digital Scale which is highly rated for its accuracy.
- Input the amount of butter or oil.
- Calculate and view results to find the potency of your cannabutter or infused oil.
Recipe:
- Input the amount of cups being used in the recipe.
- Input the number of servings.
- Calculate and view results to find milligrams per serving.
- Enjoy your edibles with accurate knowledge of how stoned you’re about to get!
You may not know how to make your own infused oil, but that’s totally okay! The HighWay has a guide just for that – How to Make Cannabis Oil for Cooking.
To make it even easier, we reviewed some of the best cannabis infuser brands so you can make your own cannabutter and infused oil with barely any effort – The Best Cannabis Infusers for Edibles.
Since you’re already making edibles, you may be interested in some of The HighWay’s own recipes! They’re super unique and have tons of ingredients you never thought could work with cannabis – Recipes

Frequently Asked Questions (FAQs)
This calculator helps you estimate how many milligrams of THC and CBD are in your homemade edibles. First it takes the THC % and CBD % of your flower, the weight in grams, and the amount of butter or oil (in cups) you’re infusing. It then factors in an average ~75% cannabinoid transfer efficiency to output:
– Total mg of THC & CBD in the infused butter/oil batch
mg of THC & CBD per cup of infusion
– Then you input how many cups you use in your recipe + number of servings to get mg of THC & CBD per serving. (Source: calculator description on page.)
When decarbing and infusing your cannabis into butter or oil, not all cannabinoids transfer perfectly from the plant material into the fat medium. A 75% efficiency is a conservative, realistic average calculation used in home-infusion estimations to give safer, more reliable potency numbers.
That’s fine! The calculator allows you to make reasonable assumptions. If you don’t know THC %, using 20% is a safe assumption. If you want to err on the more cautious side, assume 25%. For CBD %, if unknown you can assume around 0-1%.
– Always assume worst-case/stronger potency when in doubt.
– Clearly label servings with mg of THC and CBD.
– Start with a low serving size (e.g., 5 mg THC) if you’re new to edibles and wait at least 1.5-2 hours before considering more.
– Keep edibles out of reach of children and pets, and include clear dosing info.
– Remember that edibles metabolize differently (longer onset, longer duration) compared to smoking.
Several individual and contextual factors play a role:
– Your body weight, metabolism, tolerance.
– Whether you’ve eaten recently (empty stomach vs full).
– Other cannabinoids and terpenes present (entourage effect).
– The specific strain profile, how it was decarbed/infused, and how uniformly the infusion was mixed.
– The onset delay and duration of edibles (often 30–90 minutes onset, 4–8 hours or more duration).
Yes, the calculator allows you to input both THC % and CBD %. If your flower is CBD-dominant (low THC, higher CBD) you can input accordingly and get mg of both per serving. It works for both THC, CBD, or mixed infusions.
No, it’s an estimate. While the tool uses conservative assumptions (like 75% transfer efficiency) and aims for safe, realistic numbers, actual potency can vary due to decarbing quality, strain variability, measurement imprecision and mixing consistency. It should be used as a guide, and proper labeling + conservative dosing are still essential. Always err on the side of caution, especially for new users or in edible contexts.
