What you can calculate here
The library covers the popular brew methods. Ratio tools set the coffee-to-water balance for pour over, French press, and drip, in grams or by the cup. Cold brew tools scale concentrate and dilution for a smooth batch. Espresso tools work out dose, yield, and brew ratio for a balanced shot. Batch tools size a full pot or carafe for a crowd. Each one lets you tune strength so you can match your taste rather than a fixed recipe.
Who these calculators are for
New brewers use them to get a repeatable cup instead of guessing scoops. Pour-over and French-press fans dial in a ratio they can trust every morning. Espresso drinkers tune dose and yield for a balanced shot. Anyone brewing for a group can scale a batch to the right strength without watering it down.
Getting accurate results
A few habits make every cup repeatable:
- Weigh your coffee and water in grams. A scale is the single biggest upgrade to a consistent cup.
- Ratios are by weight, not volume. A level scoop varies far more than you would expect.
- Use the brew ratio as a starting point, then adjust to taste and grind size.
- For cold brew, the result is concentrate, so dilute it to taste before drinking.
Frequently asked questions
Are these calculators free?
Yes. Every coffee calculator here is free, with no account and no usage limit.
What ratio should I use?
A common starting point for filter methods is about 1 gram of coffee to 16 grams of water, then adjust to taste. The tools let you set your own ratio.
How accurate are the results?
The ratios are exact for the numbers you enter. Final taste depends on grind, water, and beans, so use the result as a reliable baseline.
Will they work on my phone?
Yes. Every tool is responsive and works the same on phone, tablet, and desktop.
Which calculator should I start with?
Pick your brew method: pour over, French press, cold brew, espresso, or a batch. Each tool links to related ones.
Do you store the numbers I enter?
No. Everything is calculated in your browser, and your inputs are not saved or sent anywhere.
