Alcohol Calories Calculator | The BAC Calculator

Estimate calories from alcohol itself using the serving size and ABV on the label. Mixers, carbohydrates, and sugar are not included.
A cocktail, sweetened drink, or beer can contain additional calories beyond alcohol.
ALCOHOL-ONLY CALORIES
Calories shown are from ethanol only: approximately 7 kcal per gram of pure alcohol.
Calories do not measure impairment. If you have been drinking, choose a sober ride.
We estimate pure alcohol as volume × ABV × 0.789 g/ml, then multiply by approximately 7 kcal per gram. This compares energy from ethanol itself; it is not a full nutrition label or a measure of safety.
The calculator estimates calories from ethanol only. It does not include carbohydrates, sugar, cream, juice, soft drinks, syrups, or food added to a drink. For total calories in a branded or prepared drink, use the product nutrition information when available.
Enter the labelled serving size, ABV, and number of servings. A larger container or a higher ABV changes the pure alcohol total and therefore the alcohol-only calorie estimate. Use what ABV means if you need help reading a label.
