Alcohol Metabolism Calculator

The Alcohol Metabolism Calculator

With the Free Online Alcohol Metabolism Calculator, you can estimate the time your body needs to metabolize alcohol.

Like all tools on my website, the Alcohol Metabolism Calculator is for educational and informational purposes only. It is not a substitute for professional medical advice, diagnosis, or treatment. The calculations provided are estimates based on generalizations, and individual metabolism rates and other physiological factors can significantly affect the actual Blood Alcohol Concentration and the time required to sober up.

How the BAC Calculator Works

This calculator uses the Widmark formula to estimate blood alcohol concentration (BAC). The calculation is based on the amount of ethanol consumed in grams (you can calculate this value using my Ethanol Calculator), body weight in kilograms, and a gender-specific metabolism rate (0.1 g/kg/hour for women and 0.15 g/kg/hour for men). It assumes that all consumed alcohol has already been fully absorbed, which results in a theoretical maximum BAC. Why theoretical? Because alcohol absorption begins with the first sip, and actual BAC can vary due to factors like liver health, metabolic rate, drinking speed, or body water content. This means the BAC could be lower or, in some cases, even higher than calculated.
