Coffee Brew Ratio Calculator
Coffee-to-water for pour-over, French press, AeroPress and espresso.
Work out the true cost of a cup of coffee at home, including beans, milk and syrup, then compare it to your usual café order to see yearly savings.
Enter what you pay for beans, how much you use per cup, and your usual café price. The calculator shows your true cost per home cup, the difference against the café, and how much you save over a year at your drinking pace.
Your home cup costs
$0.96
vs $5.50 at the café - $4.54 cheaper per cup
Yearly: $700 at home vs $4,015 out. You save about $3,315 a year.
Want to lower the per-cup number further? Buying 1 kg bags, making your own syrups, and switching to a reusable filter are the three easiest wins. If you are choosing a machine, our setup budget planner shows what each tier costs.
For drip or pour-over we assume 15 g of beans per 240 ml cup; a double espresso uses about 18 g. You can override the grams per cup in the calculator.
Not by default. Add an optional equipment cost and how many years you expect it to last, and we spread it across your yearly cups.
Add a per-cup extras cost. A splash of milk is around $0.15–0.30; a pump of homemade syrup is a few cents. Our syrup recipes are in the Drinks section.
You are paying for rent, labour, milk, cups and a margin. Making the same drink at home is usually 4–8x cheaper per cup even with good beans.
