Our Drink Calculator helps you take charge of your drinking occasion. You can add up the number of units you’ve consumed, find out how long it takes your body to process the alcohol, and learn the number of calories in your drinks.
The numbers are based on the average measurements, strengths, and calories you’d find across a range of common drinks (excluding mixers).
