Alcohol Calories Calculator

What Your Result Means
- Total Calories: The estimated calorie count for your entire order, based on standard per-serving values multiplied by the quantity.
- Calories Per Drink: The typical calorie content of a single standard serving of your selected drink.
- Total Carbs: Estimated carbohydrate grams across your order. Spirits typically have zero carbs, while cocktails and beer carry the most.
- Alcohol Content (ABV): The alcohol by volume percentage for that drink type. ABV does not change with quantity — it indicates drink strength, not total alcohol consumed.
How This Calculator Works
You select a drink category (beer, wine, cocktail, spirit, or hard seltzer), then a specific drink within that category. The tool looks up the per-serving calories, carbs, and ABV from a built-in reference table and multiplies calories and carbs by your quantity. Values are based on typical serving sizes and may differ from a specific brand or recipe.
Quick Questions
Why do spirits show zero carbs?
Distilled spirits (vodka, whiskey, rum, tequila) contain virtually no carbohydrates. The calories come almost entirely from the alcohol itself, which has about 7 calories per gram.
Are these exact calorie counts?
No — they are estimates based on standard serving sizes and common recipes. Actual values vary by brand, pour size, and preparation. Check the label for precise nutrition data when available.
How many calories does alcohol itself contain?
Pure alcohol provides approximately 7 calories per gram, making it more calorie-dense than carbohydrates or protein (4 cal/g each) but less than fat (9 cal/g). Mixers, sugar, and cream add further calories to cocktails.
What counts as one "standard drink"?
In the U.S., a standard drink contains about 14 grams of pure alcohol — roughly equivalent to a 12 oz beer (5% ABV), a 5 oz glass of wine (12% ABV), or a 1.5 oz shot of spirits (40% ABV).
