Coffee, Tea, Roasting & Dry Goods Processing calculator
Roast Batch Yield Calculator
Use this calculator to compare roasted output against the green coffee charged into the roaster. It helps roasters, production managers, and green buyers understand roast loss from moisture, chaff, quakers, and process conditions before costing the finished coffee.
What this calculator does
- Calculate roast batch yield from roasted coffee output, green coffee charged, and target roast yield.
- reviewing roast loss, green-to-roasted yield, and batch cost impact
- The result shows actual roast yield and gap to the expected roast profile.
Formula used
- Roast Batch Yield = roasted coffee output ÷ green coffee charged × 100
- Gap to target = target roast yield - roast batch yield
Inputs explained
- Roast Batch Yield affected amount: undefined
- Roast Batch Yield total amount: undefined
- Roast Batch Yield target rate: undefined
How to use the result
- Use it to adjust green coffee requirements, update costing, or investigate abnormal roast loss.
- Treat the result as a planning estimate until it is checked against actual roast logs, green and finished weights, moisture readings, grinder or blender records, packaging checkweigher data, lot traceability, labor reports, utility bills, and released production records.
Common questions
- What is the roast batch yield calculator for? It calculates the percentage of green coffee that became roasted coffee.
- What information should I enter? Use roasted output, green charge weight, and target yield on the same lb or kg basis.
- What does the result tell me? The result shows actual roast yield and gap to the expected roast profile.
- When is the result only an estimate? Treat the result as a planning estimate until it is checked against actual roast logs, green and finished weights, moisture readings, grinder or blender records, packaging checkweigher data, lot traceability, labor reports, utility bills, and released production records.
