CBD Cost per mg Calculator | Estimate Product Value

When it comes to CBD, price tags alone don’t tell the full story. What truly matters is the cost per mg — the amount you’re paying for each milligram of CBD, especially when considering factors like absorption and waste.
That’s where our CBD Cost per mg Calculator comes in. It breaks down product value so you can compare tinctures, capsules, or vapes on a level playing field. This blog post explains all the key input factors and shows you how to use the calculator step-by-step to save money and optimize your CBD intake.

How to Calculate CBD Cost per mg By Use Our Calculator Step-by-Step Guide

Step 1: Enter Total CBD in Product

Look for the label’s “Total CBD” value (e.g., 1000mg) and enter it. This is not per serving.

Step 2: Input the Total Product Price

Enter the price you paid, before or after discounts. Exclude tax unless adding it manually.

Step 3: View Cost per mg

The calculator instantly divides price by CBD mg to give a raw cost per mg — like $0.05 per mg.

Step 4: Enter CBD per Dose

Type how many mg you consume per serving — this might be 25mg, 33mg, or more depending on the format.

Step 5: Choose Usage Days

Choose oil, capsule, edible, vape, or topical. This changes the bioavailability calculation automatically.

Step 6: Set Waste Allowance (Optional)

Adjust the waste percentage based on product quality or usage habits. Most people leave this at 10–15%.

Step 7: Review Final Metrics

The calculator displays:
  • Raw cost per mg
  • Effective mg absorbed per dose
  • Adjusted cost per mg absorbed
  • Dose efficiency score
You can even export this to PDF to compare brands or archive your findings.

Main Cost Factors in the CBD Cost per mg Calculator

The calculator analyzes more than just label price. Here’s what it evaluates for real CBD efficiency:

Total CBD Content in the Product (mg)

This is the full amount of cannabidiol in the bottle, package, or container — not per dose. You’ll typically find this on the label as “Total CBD: 1000mg.”

Product Price ($)

What you paid or will pay for the full product. This includes discounts but excludes shipping and tax unless you add it manually.

Cost per mg (Raw)

This is a simple division: Price ÷ Total mg. It tells you how much each mg of CBD costs in basic form.

CBD per Serving (mg per dose)

Not every product makes this clear. Use the label to determine how many mg you’re consuming in one dose — e.g., 25mg per gummy or 33mg per dropper.

Absorption Rate (Bioavailability)

CBD formats absorb differently in the body:
  • Oil/Tincture: ~35–40%
  • Edibles/Capsules: ~20–25%
  • Vape: ~60%
  • Topical: ~8–10%
This lets the calculator determine the effective cost per absorbed mg.

Waste Factor (%)

Even high-quality products have some waste — think spills, underdosing, oxidation. We factor in a default 10–15% waste unless customized. 

Final Output: Real Cost per Effective mg

This is the bottom-line result: how much are you actually paying per usable mg of CBD? It’s what separates premium value from overpriced products.
