Cost in Use vs. Price per lb: The Number That Actually Matters

A cheap bag of beans might be the most expensive ingredient in your shop. Here’s how to tell the difference.

If you’ve been in the craft chocolate world for more than a few months, you’ve had the conversation. Someone at a tasting event or on a forum mentions they’re paying $4.50 a lb for their beans, and you quietly wonder how that’s possible when you’re paying $6.50 for yours.

The uncomfortable truth: their beans might actually be costing them more than yours. They just don’t know it yet.

The Vanity Metric

“Price per lb” is the number everyone knows. It’s on the invoice, it’s easy to compare, and it feels like the definitive measure of what your raw material costs. But it tells you almost nothing about what that material will actually cost once it becomes chocolate.

Price per lb ignores yield. It ignores moisture. It ignores shell-to-nib ratio. It ignores the winnowing losses that vary dramatically between bean varieties and roast profiles. It ignores everything that happens between your loading dock and your wrapper.

It’s like evaluating a house based solely on the asking price without considering property taxes, maintenance, insurance, or the fact that the roof needs replacing next year.

The Real Number

“Cost in use” is the price of the material you actually put into your product. It accounts for every loss between procurement and production.

Here’s a simplified example. Two bags of beans, same weight:

Bean A: $4.50/lb. High cleaning needs result in 5% loss up front. 7.6% moisture loss during roasting due to high initial moisture beans, a 23% recovery during winnowing that results in a nib-in-shell level of 4.5% means your cost in use for this inexpensive bean is actually $6.62 - or a 38% increase in cost in use vs purchase cost.

Bean B: $6.50/lb. Cleaner beans resulted in only 1% loss up front, a 4.5% moisture loss during roasting as a result of having good starting bean moistures results in better winnowing separation - only a 1% nib-in-shell loss with a overall yield of 78% - which results in a total cost of $8.83 - only a 27% difference vs purchase price - which is an 11% hit (or gain) against your margin - depending on which bag you buy.

Why This Math Is Hard to Do (Without Help)

The reason most makers default to price-per-bag thinking isn’t laziness—it’s complexity. Calculating true cost-in-use requires tracking data across multiple production stages, and those numbers shift with every new lot, every seasonal variation, and every change in your roast profile.

This is one of the core reasons Atlas tracks bean lots from intake through processing. When you log a new lot, record your shell ratio and moisture readings, and run it through winnowing, the system calculates your actual nib yield and cost-per-kilogram automatically. You don’t need a spreadsheet with twelve tabs. You need a single number that updates as your data improves. And it automatically calculates and cascades - and tracks - this information through all of Atlas.

Sourcing Decisions, Reframed

Once you start thinking in cost-in-use terms, your entire sourcing strategy shifts. That premium Tanzanian lot at $8.50/kg might look expensive on paper, but if it delivers high winnowing efficiency and low moisture AND tastes great, its cost-in-use could undercut a “budget” bean by a meaningful margin.

More importantly, cost-in-use thinking gives you the financial clarity to pay fair premiums to farmers growing exceptional cacao. When you know exactly what a bean is worth in your process, you can afford to pay for quality—because you can see the return.

Stop comparing invoices. Start comparing what’s actually landing in your melangeur.
