Alcohol Calorie Calculator
Alcoholic beverages can be a hidden source of significant calories in your diet. This calculator shows you exactly how many calories are in your drinks based on the type, volume, and alcohol content, helping you make informed choices about your alcohol consumption.
Alcohol (ethanol) contains 7 calories per gram, making it the second most calorie-dense macronutrient after fat (9 cal/g). Unlike carbohydrates and protein (4 cal/g each), alcohol provides essentially no nutritional value. These are often called "empty calories" because they contribute energy without vitamins, minerals, or other beneficial nutrients.
The calorie content of alcoholic beverages comes from two sources: the alcohol itself and any residual sugars, carbohydrates, or added mixers. A standard 355 mL (12 oz) beer at 5% ABV contains about 14 grams of alcohol (98 calories from alcohol alone) plus another 40-60 calories from carbohydrates, totaling roughly 150 calories. A glass of wine (150 mL at 13% ABV) contains about 120 calories, mostly from alcohol.
For those watching their calorie intake, alcohol can significantly impact weight management goals. A few drinks per week may not matter much, but regular consumption adds up quickly. Four beers on a weekend equals about 600 calories, which could negate a day's worth of calorie deficit for weight loss. Being aware of these calories helps you budget them into your overall nutrition plan.
