*Please note — The calculator above is a way to estimate your blood alcohol level, but your actual BAC will vary depending on additional factors including: hydration levels, recent food ingestion, fluid intake, kidney function, and others. The best way to determine BAC is via blood tests. The next best way is to use a breathalyzer device.
Below is a chart to give you an idea of the effects that alcohol will have on physical response to varying levels of alcohol ingestion.
