🍷 BAC Calculator — Estimate Your Blood Alcohol Content
Use our Free Online BAC Calculator to estimate your Blood Alcohol Concentration (BAC) — the approximate percentage of alcohol in your bloodstream — based on information you provide about your drinks, body, and time. It’s quick, easy, and works right in your browser without any login or download.
- This tool gives an informational estimation only. It’s designed to help you understand how alcohol affects your body and support safer choices — it does not replace medical advice or a breathalyzer test.
🧠 How the BAC Calculator Works
To estimate your BAC, the calculator considers several important factors:
Body weight and gender — these influence how alcohol is distributed and metabolized in your body
Amount and strength of alcohol consumed — including beer, wine, spirits, or other beverages
Time since your first drink — because alcohol leaves your body slowly over time
Once you enter this information, the calculator estimates your BAC level and shows how long it may take until your BAC returns toward zero.
🧪 What BAC Means
Blood Alcohol Content (BAC) is shown as a percentage that represents grams of alcohol per 100 milliliters of blood. For example, a BAC of 0.08% means there are 0.08 grams of alcohol per 100 ml of blood. Higher BAC levels mean stronger effects on coordination, judgment, and reaction time.

⚠️ Important Safety Reminder
