The BAC Calculator

CORE ALCOHOL TOOL

Alcohol Calories Calculator.
Made clear.

Estimate calories from alcohol itself using the serving size and ABV on the label. Mixers, carbohydrates, and sugar are not included.

ALCOHOL-ONLY CALORIES

Start with what is on the label.

Describe the drink

Calories shown are from ethanol only: approximately 7 kcal per gram of pure alcohol.

THE MATH

Pure alcohol ×
7 calories.

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.

What this calorie result includes

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.

How to use the result

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.

Calories do not measure alcohol impairment. Do not use a calorie total, standard-drink count, or online BAC estimate to decide whether to drive, operate equipment, or make a medical or legal decision.
