Morning after calculator

Work out your blood-alcohol content, and get a rough idea of when it'll leave your system.

The morning after calculator should not be used in place of sensible caution. If you're drinking, don't drive. If you're driving, don't drink.

Summer's here! It's festival season, and the sun is ... sometimes out.

It can be tempting to have more than a few swift ones in a beer garden, but what happens the following morning? How do you know if you're still over the limit?

Our morning after calculator will give you a rough idea. Just enter your sex and weight, along with how much you've drunk and we'll do the rest. If you’re hungover, the calculator can also estimate when the alcohol should be out of your system. 

No blood alcohol calculator is 100% accurate, as there are a number of factors that impact how your body processes alcohol. This tool should be used for reference purposes only, and shouldn't be used to determine whether you're fit to drive. If in doubt, do not drive.
