Drink Calculator

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).

* On average your body processes about one unit of alcohol every hour – and nothing can speed this up. This is an estimate only as the time taken to process the alcohol will depend on a variety of factors including gender, age, weight, health and lifestyle.
**The calories you burn vary widely depending on your weight, exercise intensity and other factors.
