The Cost Ledger

The Real Economics of Bean-to-Bar Chocolate at Home

The single biggest cost in a homemade bar is the beans. Fine-flavor cacao runs roughly $8–$40 per kilogram green (unroasted), and you lose around 20 percent of that weight as shell during roasting and winnowing — so a bar that's 70 percent cacao needs noticeably more than 70 percent of its finished weight in beans. The ledger builds that husk loss into the bean line for you.

Sugar is almost free by comparison (around $2/kg), which is why higher-percentage dark bars cost more to make than sweeter bars of the same weight: more expensive cacao, less cheap sugar. Packaging is the quiet line item — molds amortize away, but printed wrappers, foil, and labels can add $0.30–$1.50 to every bar.

Equipment is the honest reckoning. A melanger is a fixed cost you spread across every bar it will ever make: an $800 kit amortized over 2,500 bars adds about $0.32 per bar — trivial — but only if you actually make 2,500 bars. The ledger lets you set the amortization so you can watch the per-bar cost fall as you commit to the hobby.

Put it together and the result surprises most people: at typical home volumes, a bar often costs more to make than a comparable craft bar costs at retail — until the machine is paid off. That's the point of the break-even panel: it counts the bars until your kit has paid for itself versus buying retail, after which every bar is pure savings. People make chocolate at home for control, learning, and the pleasure of it, the same reasons people bake their own bread. The savings, when they come, show up at scale or with cheaper beans.
