Three small calculations for your own coffee routine. All starting values are hypothetical; they are not prices, recommended doses or freshness advice. Results stay in this page.
Bean cost per preparation
Price ÷ net weight × dose. Excludes waste, ingredients, equipment, cleaning and electricity.
How long will the bag supply last?
Net weight less your unserved allowance, divided by dose and daily preparations. This is inventory arithmetic, not a storage or food-quality recommendation.
Yearly care allowance
Use the costs and number of purchases you expect during one year. The tool does not choose a cleaning or replacement schedule for your appliance.
