Cannabis Infusion Calculator + Recipes (Excel Spreadsheet)

Stop guessing. Start dosing accurately.

Most edible calculators ignore a critical factor: absorption loss. When you strain cannabutter through cheesecloth, you lose 2-4 tablespoons of butter stuck in the plant material. That throws off every dosing calculation.

This spreadsheet accounts for it.

What's included:

- Imperial & Metric calculators — works worldwide

- Flower AND concentrate support — shatter, wax, dabs with different efficiency rates

- THC + CBD tracking — for balanced ratios

- Gummy/Edible recipe calculator — figure out mg per serving, or reverse-calculate how much infusion you need for a target dose

- Full recipes — butter, coconut oil, MCT oil, olive oil, and alcohol tinctures

- Double boiler method — more consistent than oven decarb, works for flower AND concentrates

What makes this different:

✓ Accounts for fat/alcohol absorbed by plant material (most calculators don't)

✓ 90% efficiency for concentrates vs 75% for flower (because they're already processed)

✓ Reverse calculator — "I want 25mg gummies, how much butter do I use?"

✓ Works offline — no website needed, no ads, no data collection

✓ One file, lifetime use

Just plug in your flower weight, THC%, and amount of butter/oil. The spreadsheet does the rest.

Works with: Excel, Google Sheets, LibreOffice, Numbers
