Cost per cup
Enter what your tin cost and how big it is, and compare a bowl at home with the same drink from a cafe.
Cost
Modelled on one standard 2 g bowl a day for 30 days. Log brews and this switches to your real history. At these prices the tin pays for itself after 7 bowls.
Questions
Divide the price of the tin by its weight in grams to get a cost per gram, then multiply by the dose you actually use, usually 2 g. The calculator does that against your real brew log, so the figure reflects the bowls you drank rather than an assumed dose.
Almost always, and the calculator shows where the line is: it works out what the same number of bowls would have cost at your local cafe price and how many bowls it takes for the tin to pay for itself.
Yes. If your cellar has a tin, the cost calculator starts from the price and weight you recorded for the most recent one, and you can type over either figure to model a different tin.
