Monthly Coffee Budget
Estimate home brewing spend by day and month.
Results update as you type. Units are grams unless stated otherwise.
How to use this calculator
Enter your own measurements in the labeled fields. The result is recalculated immediately and is intended as a planning aid for real home brewing.
How to interpret the result
Assumes the same coffee and other daily expenses on each of 30 days. Does not include gear purchase costs.
Record the result alongside your actual brew and adjust after tasting. Coffee beans, grind distribution, water and brewer design can all change the outcome even when two recipes use identical numbers.
Questions about this tool
Is this a guaranteed perfect recipe?
No. The tool performs arithmetic or offers a starting structure. It cannot measure extraction or taste your coffee.
Can I use a different coffee or brewer?
Yes. Treat the quantities as a starting point and tune grind, water and pouring for your setup.
