A standard shot of vodka, which is typically 1.5 ounces (about 42-45 ml) and 80 proof (40% alcohol by volume), contains approximately 96 to 97 calories. This calorie count comes entirely from the alcohol content, as vodka contains no carbohydrates, fat, or protein

. The calories in vodka vary slightly depending on the proof (alcohol concentration):

• 70 proof (35% ABV): about 85 calories per shot
• 80 proof (40% ABV): about 96-97 calories per shot
• 90 proof (45% ABV): about 110 calories per shot
• 100 proof (50% ABV): about 124 calories per shot

These calories come from alcohol, which provides roughly 7 calories per gram, making vodka a relatively low-calorie alcoholic beverage compared to others like beer or wine. However, mixers can significantly increase the total calorie content of a drink

. In summary, a typical shot of 80-proof vodka has about 96-97 calories. Higher proof vodkas have more calories proportionally to their alcohol content.
