Alcohol Burn-Off Calculator

On the widely-cited population average, a healthy adult liver processes roughly one standard drink per hour. This tool multiplies your drink count by one hour, then subtracts however long has already passed. It is a rough average, not a measurement of your body.

This calculator uses the US standard drink: about 14 g (0.6 fl oz) of pure alcohol — roughly a 12 oz beer at 5% ABV, a 5 oz glass of wine at 12%, or a 1.5 oz shot of spirits at 40%. A pint, a large glass of wine, or a strong craft beer can easily be 1.5–2 standard drinks.

No. Actual blood alcohol concentration depends on body weight, sex, food, medications, liver health, and more — this tool models none of that, and only a breathalyzer or blood test measures your real BAC. If you are going to drive, the only reliably safe choice is not to drink beforehand.

Yes — food, especially with fat and protein, slows how fast alcohol reaches your bloodstream and lowers your peak BAC for the same amount of drinking. It doesn’t meaningfully change how fast your liver clears alcohol once it’s absorbed, which is what this calculator estimates.

Confusion, vomiting, seizures, slow or irregular breathing, pale or blue-tinged skin, low body temperature, or unresponsiveness. These are a medical emergency — call your local emergency number immediately and stay with the person until help arrives.
