Morning after calculator

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

The Confused.com 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.

The morning after a heavy night of drinking is never pleasant. But when it comes to driving, 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. Use the tool for reference purposes only, it shouldn't be used to determine whether you're fit to drive. We can’t emphasize this enough, if in doubt, do not drive.
