How to Use This Calculator

Enter the number of mold cavities and the volume of each cavity in mL.
Set chocolate density (solid dark ≈ 1.31 g/mL, milk ≈ 1.25 g/mL) and your waste percentage.
The calculator returns total chocolate needed in grams and oz, chocolate per cavity, waste allowance, and estimated cost.
Temper and pour the calculated chocolate amount, then tap molds to release air bubbles before setting.

How the result changes with Cavity Volume

Cavity Volume	Total Chocolate Needed
20	686.4 g
70	2,402.4 g
130	4,461.6 g
180	6,177.6 g

What each input means

Number of Cavities: Total mold cavities to fill. Count all cavities across all mold trays you plan to use.
Cavity Volume: Volume of each cavity in milliliters. Standard bonbon cavities are 7-10 mL, bars are 30-80 mL, figures can be 100+ mL.
Chocolate Density: Density of tempered chocolate in g/mL. Dark ~1.30, Milk ~1.28, White ~1.25. Higher cocoa content = slightly denser.
Waste Percentage: Expected waste from overflow, scraping, and residual chocolate. Beginners: 15-20%. Experienced: 5-10%.
