Caffeine calculator
How much caffeine is actually in your coffee — added up by drink and serving, and measured against the daily safe limit.
A shot of espresso has less caffeine than a mug of drip, and cold brew has the most of all — the intensity of a drink rarely matches its caffeine. Pick what you drink and how much, and this calculator totals the milligrams and shows where you land against the 400 mg daily maximum.

Common questions
How much caffeine is in a cup of coffee?
A standard 8 oz (240 ml) cup of drip coffee has about 95 mg of caffeine. A single espresso shot has around 63 mg, pour-over runs slightly higher than drip, and cold brew can reach 150–200 mg per serving. Decaf has only about 2–5 mg. The calculator totals it up across everything you drink in a day.
How much caffeine is too much?
The FDA considers up to 400 mg of caffeine a day safe for most healthy adults — roughly four 8 oz cups of drip coffee. People who are pregnant are usually advised to stay under 200 mg. The calculator shows your total against both limits so you know where you stand.
Does espresso have more caffeine than drip coffee?
Per serving, no. A single espresso shot has about 63 mg of caffeine versus roughly 95 mg in a full 8 oz mug of drip. Espresso has more caffeine per ounce, but you drink far less of it, so a normal mug of drip delivers more caffeine overall.
How can I cut caffeine without giving up coffee?
Switch some cups — especially the afternoon ones — to a good Swiss Water decaf, which keeps 97%+ of the caffeine out while preserving most of the flavor. Drinking smaller servings of full-strength coffee works too. Modern decaf is good enough that an evening cup needn't feel like a downgrade.
