Caffeine Intake Calculator

Add up your daily caffeine from drinks and see it against general guidance.

How much caffeine you're really having

Caffeine adds up across the coffees, teas, energy drinks and colas of a day, and it is easy to lose track. This totals your caffeine intake from what you drink, so you can see it against the general daily amounts often cited as moderate for most healthy adults.

Sensitivity varies, and timing matters

General guidance suggests a moderate daily caffeine amount is fine for most healthy adults, but individual sensitivity varies a lot — some people feel jittery on a single coffee while others tolerate far more, and factors like pregnancy lower the recommended amount considerably. Timing matters too: caffeine lingers for hours, so drinks later in the day can disrupt sleep even if you feel fine. If caffeine leaves you anxious, jittery or sleeping poorly, that is worth heeding regardless of the numbers. This is general information, not medical advice; if you are pregnant, have a health condition, or are concerned about caffeine, your doctor is the right source of guidance.
