About the BAC Calculator

The BAC Calculator is a form that you can fill out. Upon completion we will instantly compute your estimated blood/breath alcohol concentration ("BAC") based on the information that you have provided and return that estimate to you. It is presented as a public service. Its primary purpose is to provide useful information about the responsible use of alcohol. Most importantly, NEVER DRINK AND DRIVE!


It would be extremely foolish to pretend that our BAC Calculator can tell you what your BAC actually is, first because it would open us up to an incredible amount of potential liability, and secondly that other factors will always impact the actual reading from an actual breath alcohol analysis device. The calculator is only designed to be a rough estimate, and is NEVER intended to replace an actual breath alcohol analysis device.

A person's actual BAC is dependent on many complex factors, including their physical condition (body composition, health etc...) and what they have recently ingested (including food, water, medications and other drugs).

The results that are generated are rough estimates of an average healthy person's BAC assuming typical beverage sizes, recipes and alcohol content. The BAC estimates generated by the calculator should not be used to infer anyone's fitness to work, drive or perform any other task or duty.
