Never Drive Impaired
Even small amounts of alcohol can impair your driving ability. When in doubt, don't drive.
Time is the Only Cure

Stay Hydrated
Drink water between alcoholic beverages to stay hydrated and pace yourself.
Eat Before Drinking
Food slows alcohol absorption and can help reduce peak BAC levels.
Quick BAC Calculator FAQ
How accurate is the quick BAC calculator?
Our quick calculator uses the same scientifically validated Widmark formula as our detailed calculator. It provides good estimates for most people, but individual factors can affect actual BAC levels.
What's the difference between quick and detailed calculators?
The quick calculator focuses on essential inputs for fast results, while the detailed calculator includes additional factors like drink types, custom beverages, and more comprehensive analysis.
Can I use the drink presets for mixed drinks?
The presets are designed for standard drinks. For mixed drinks or cocktails, estimate the number of standard drinks they contain or use our detailed calculator for custom beverages.
Why does the calculator ask for drinking duration?
Your body metabolizes alcohol over time. The duration helps calculate how much alcohol has been eliminated since you started drinking, providing a more accurate current BAC estimate.
