Estimate coffee bean kilograms and whole bags from drink count, recipe dose, waste and selected bag size.
Your results
Calculation breakdown
- Bean requirement
- drinks × dose grams × (1 + waste) ÷ 1,000
Worked example
Five hundred drinks at a 20 g dose require 10 kg by recipe or 10.3 kg with 3% dial-in waste, so eleven 1 kg bags.
Assumptions
- Every forecast drink uses the same entered coffee dose.
- Bag rounding does not deduct existing opened stock.

How this calculator works
Estimate roasted coffee bean kilograms and whole retail or wholesale bags from drink count, dose per drink and dial-in waste. The explicit dose and waste fields suit different espresso recipes without assuming one café standard. Inputs and intermediate values stay visible so an Australian club, venue or food team can reproduce the estimate and replace assumptions with measured operating data.
Frequently asked questions
Which inputs matter most for the coffee bean requirement result?
Use the actual recipe dose, forecast drink mix, grinder retention and measured dial-in or purge waste for the venue. Keep the measurement period and definitions consistent when comparing results.
What is not captured by this coffee bean requirement calculation?
Double shots, batch brew, decaf, staff drinks, stock already open and demand variability can change purchasing needs. Treat the output as one planning measure rather than a complete operating decision.
When should the coffee bean requirement estimate be recalculated?
Recalculate when quantities, participants, rules, equipment, packaging or operating conditions change. For this topic, use the actual recipe dose, forecast drink mix, grinder retention and measured dial-in or purge waste for the venue.
