Connecting roast style to sellable output
A coffee yield calculator estimates roasted output weight from green input and roast-level assumptions.
It helps align production planning, packaging targets, and purchasing decisions.
Yield forecasting is especially useful when pricing and fulfillment commitments depend on tight inventory control. A consistent model reduces surprises in daily operations.
Yield Formula
Simple output and loss math
Roasted Output = Green Input × Yield Factor
Weight loss is the difference between green input and roasted output.
As actual data accumulates, refine factors by roast style and origin. That improves margin planning and purchase timing decisions.
Example
Medium roast planning case
For 60 kg green coffee at medium roast with 84% factor, expected roasted output is 50.4 kg and loss is 9.6 kg.
That estimate can be converted directly into bag counts and projected revenue, helping teams validate production goals before roasting starts.
Applications
Forecasting and operations
Use for green purchasing, roast schedule planning, and fulfillment commitments.
It also supports pricing conversations by making the connection between roast level, output, and margin more transparent.
Tips
Keep factors current
Review modeled yields against actual weekly production data. Small periodic updates prevent large forecasting errors over time.
Track yield by origin and roast style because real-world loss varies by lot and endpoint.
Update assumptions quarterly so pricing and forecasting remain reliable.
Frequently Asked Questions
What is coffee yield in roasting?
Yield is the roasted output weight relative to green input weight after moisture and volatile loss. It is a core production metric because it directly affects sellable volume and pricing assumptions.
Does roast level change yield?
Yes. Darker roasts generally have greater mass loss and lower roasted output percentage due to longer development and higher thermal exposure.
Can this help inventory planning?
Yes. It converts green purchase weight into expected sellable roasted output so teams can plan packaging, fulfillment, and reorder timing more accurately.
Should I still track actual batch loss?
Yes. Use actuals to calibrate these assumptions for your equipment and lot mix, then update model factors as crop and process characteristics change.
