One serving. One day. A clear total.

- 2. Enter the number of servingsCount how many servings of that same size you want to include in one day. Use a separate entry if the amount changes.
- 3. Check the breakdownEach entry is multiplied by its frequency. The daily total adds all complete entries, without treating missing information as zero.

What this number means
Your result is the sum of the labeled CBD amounts you entered. It is not a measurement of absorbed CBD, a check of the product’s composition or a personal recommendation. Do not use it to adjust a prescribed treatment.
The FDA reports that it has not found sufficient information to establish how much CBD can be consumed, and for how long, before causing harm. For decisions about using CBD, speak with a healthcare provider. Read the FDA explanation of CBD safety uncertainties.
Common questions
Does this calculator tell me how much CBD to take?
No. You choose every serving amount and frequency. The calculator adds those amounts; it does not recommend a dose, assess safety or predict an effect.
How do I find CBD per serving?
Use the CBD amount for the specific serving on your label. For oil labeled only with bottle totals, the Strength Calculator converts total CBD and bottle volume into CBD per mL and per measured serving.
What if my servings have different amounts?
Create a separate entry for each amount. For example, count one serving size in the first entry and a different size in the second. Do not count the same serving twice.
Can I include gummies, capsules and oil?
You can total the labeled CBD amounts from these formats if you know CBD per serving. Adding them is only arithmetic; it does not establish that combining products is appropriate or safe, or that equal mg amounts have equal effects.
Does it include THC, CBN or other ingredients?
No. Enter CBD only. Combined cannabinoid totals and hemp extract weight cannot be substituted for CBD. Other ingredients and their interactions are not assessed.
Why does it not ask for my body weight?
This tool calculates a total from your entries. It does not use a weight-based formula to prescribe or suggest CBD intake.
Are my entries saved?
No. The calculation runs in your browser, without saving entries to your device or sending them to a calculator service. Reloading or leaving the page clears the entries. You can copy the result yourself.
