A standard shot of vodka, which is typically 1.5 ounces (42 grams) of 80 proof (40% alcohol) vodka, contains about 96 to 97 calories. These calories come entirely from the alcohol content, as vodka has zero carbohydrates, fat, and protein

. The calorie count can vary slightly depending on the proof (alcohol concentration) of the vodka:

• 70 proof (35% alcohol): about 85 calories
• 80 proof (40% alcohol): about 97 calories
• 90 proof (45% alcohol): about 110 calories
• 100 proof (50% alcohol): about 124 calories

In summary, for a typical shot of 80 proof vodka, expect roughly 96-97 calories. Higher proof vodkas have more calories due to higher alcohol content.
