How to Use the Home Cafe Bean Consumption Calculator
Brewing coffee at home every day can mean running out of beans right when you need them most. This calculator takes your bean bag size, grams used per cup, and cups per day, then works out how many days the bag lasts, the estimated empty date, and — accounting for shipping time — the recommended date to reorder. The reorder date is calculated three days before the bag actually runs out, so you always have a fresh bag ready before the old one is gone. If you're on a coffee subscription, this is also a handy way to check whether your delivery interval actually matches your drinking pace.
