About

Blood Alcohol Concentration (BAC) Calculator is an online tool that estimates the concentration of alcohol in your body and shows how long it will take to sober up. However, keep in mind that the results are only approximate and this alcohol calculator can in no way be evidence of sobriety.

Our mission

Our goal is to become the go-to resource for everything related to alcohol in Ireland—from understanding its effects on the body to knowing the alcohol driving limits in Ireland.

We strive to provide accurate and reliable information to help people make informed decisions about alcohol consumption and responsible driving.

A key part of our mission is our BAC Calculator, a tool designed to estimate your blood alcohol concentration (BAC) and give an approximate time for sobering up based on your drinking habits. While the results are estimates, they serve as a valuable guideline for understanding how alcohol affects your body.

By offering both informational resources and practical tools, we aim to promote awareness, safety, and responsible alcohol consumption across Ireland.

How does it work

The results of this Blood Alcohol Concentration Calculator are obtained by calculating the ratio between consumed alcohol content, its strength and human's weight. Gender differences are taken into account as well. The algorithm was based on the fact that the consumed alcohol evenly distributes in the fluid in the body, which makes up 50-65% of the total human weight. However, there are many other factors that this calculator cannot take into account, so the results are only approximate.
