Vodka is one of the lower-calorie alcoholic drinks, but it’s not calorie-free. A standard 1.5-ounce shot of 80-proof vodka contains about 97 calories. That’s comparable to a medium banana or a tablespoon of olive oil. Whether those calories add up depends largely on how much you drink and what you mix it with.
Where Vodka’s Calories Come From
Plain vodka contains zero carbohydrates and zero sugar. Every calorie comes from the alcohol itself. Pure ethanol packs 7 calories per gram, making it nearly as energy-dense as fat (9 calories per gram) and significantly more calorie-dense than protein or carbohydrates (4 calories per gram each). Since 80-proof vodka is 40% alcohol by volume, that ethanol content is doing all the caloric heavy lifting.
This also means higher-proof vodka has more calories. Moving from 80-proof (40% alcohol) to 100-proof (50% alcohol) bumps the calorie count up proportionally, roughly to 124 calories per 1.5-ounce shot. The math is simple: more alcohol per sip means more calories per sip.
How Vodka Compares to Other Drinks
At 97 calories per standard serving, vodka sits on the lighter end of the alcohol spectrum. A 12-ounce regular beer typically runs 150 calories or more, and a 5-ounce glass of wine lands around 120 to 130 calories. Light beer comes closest, at roughly 100 calories per can, but you’re drinking a much larger volume of liquid to get a similar amount of alcohol.
The comparison gets more interesting when you consider that a “standard drink” of each contains roughly the same amount of pure alcohol. A 1.5-ounce shot of 80-proof vodka, a 12-ounce beer, and a 5-ounce glass of wine all deliver about the same ethanol. So the calorie difference really comes down to everything else in the drink: the residual sugars in wine, the carbohydrates in beer, and whatever you pour into your vodka glass alongside it.
Mixers Are the Real Calorie Problem
A shot of vodka on its own is 97 calories. A vodka and tonic, according to UF Health, jumps to about 189 calories for a 7-ounce pour. That’s nearly double, and tonic water is one of the lighter mixers. Cranberry juice cocktail, orange juice, and ginger beer all bring significant sugar and calories along for the ride. A vodka cranberry at a bar can easily hit 200 to 250 calories depending on how generous the pour is.
If you’re watching calories, club soda or seltzer with a squeeze of lime keeps your drink close to that baseline 97. Diet tonic works the same way. The difference between a vodka soda and a vodka cranberry over three or four drinks in an evening can be 400 to 600 extra calories, which is the equivalent of a full meal.
Flavored Vodka Adds Hidden Calories
Plain, unflavored vodka has a clean nutritional profile: zero sugar, zero carbs, calories from alcohol alone. Flavored vodkas complicate this. Many brands add sugar or sweeteners to achieve those vanilla, citrus, or berry flavors, and they aren’t required to list nutrition facts on the label. A flavored vodka can run 10 to 30% higher in calories than its plain counterpart, depending on the brand and how much sugar is added. Some “whipped cream” or dessert-style flavored vodkas push well past 100 calories per shot.
If the label doesn’t list sugar content, a good rule of thumb is that the sweeter it tastes, the more calories it contains beyond what the alcohol alone would account for.
How Your Body Handles Alcohol Calories
Alcohol calories behave differently from food calories in a way that matters. Your body can’t store ethanol, so it prioritizes burning off alcohol before anything else. While your liver is processing that vodka, the fat, protein, and carbohydrates from the food you’ve eaten get pushed to the back of the metabolic line, making them more likely to end up stored as fat.
Alcohol calories also aren’t available to your muscles the way food calories are. They don’t convert to glycogen, the stored energy your body taps during physical activity. So while 97 calories from a shot of vodka and 97 calories from a handful of almonds register the same on paper, your body uses them in fundamentally different ways. The vodka calories essentially become metabolic busywork for your liver, while the food you ate alongside it waits in a holding pattern.
How Vodka Calories Add Up in Practice
A single shot at 97 calories is modest. The problem is that few people stop at one, and pours at home tend to be heavier than the standard 1.5 ounces. Studies on self-poured drinks consistently show that most people overpour spirits by 20 to 50%, which means your “one drink” might actually be closer to 130 to 145 calories before any mixer enters the picture.
Three vodka sodas at a bar is roughly 300 calories. Three vodka cranberries could be 600 to 750. A night of four or five mixed drinks with sugary mixers can rival a full day’s worth of snacking. For someone having a couple of drinks a few times per week, the caloric impact depends almost entirely on what’s in the glass alongside the vodka. The spirit itself is relatively lean. Everything around it is where the numbers climb.
