You're at the bar. It’s a Friday night, the music is a bit too loud, and you're trying to be "good" this weekend. You order a vodka soda. Why? Because we’ve all been told it’s the "skinny" drink. The choice of champions for anyone watching their waistline. But let's get real for a second—do you actually know how many calories is a shot of vodka, or are you just following the crowd?
Honestly, the answer is simpler than most people think, but the way it interacts with your body is surprisingly complex. A standard shot of 80-proof vodka contains almost exactly 97 calories. That’s it. No carbs, no sugar, no fat. Just ethanol and water.
But wait.
Before you go ordering a double, you need to understand that "97 calories" is a bit of a moving target. Not all vodka is created equal. If you're pouring a 100-proof bottle, you're looking at about 124 calories per shot. The math is tied directly to the alcohol content. Alcohol itself contains about 7 calories per gram. That’s more than carbs or protein (4 calories per gram) but less than fat (9 calories per gram).
The Proof Problem
When we talk about how many calories is a shot of vodka, we usually assume a 1.5-ounce pour. That’s the standard jigger size in the United States.
If you’re at a dive bar where the bartender "heavy pours," you might be getting 2 ounces. Suddenly, that "97-calorie drink" is actually 130 calories. If you’re drinking a flavored vodka—think vanilla, whipped cream, or peach—the math changes again. Most major brands like Smirnoff or Absolut keep their flavored versions around the same calorie count, but some brands add sugar after distillation. That’s where they get you.
Check the label. If it’s "infused," you’re usually safe. If it’s a "liqueur" (even if it says vodka on the front), you’re basically drinking liquid candy.

Why Your Body Doesn't Treat These Calories Like Food
Here is the thing. Your body views alcohol as a toxin. Not a "scary" toxin in small amounts, but something that needs to be cleared out immediately.
When you drink that shot, your metabolism hits the "pause" button on burning fat. It shifts all its energy to processing the acetate (what alcohol turns into). So, while the 97 calories in that shot of vodka don't seem like much, they effectively stop your body from burning the pizza you ate earlier. This is a nuance people often miss. It isn't just about the number; it's about the metabolic stall.
Mixing Your Way to Trouble
You want to know the quickest way to ruin the low-calorie benefit of vodka? A mixer.
- Tonic Water: People think this is just bubbly water. It isn't. It’s loaded with sugar. A vodka tonic has almost as many calories as a regular soda.
- Orange Juice: You’re looking at about 150-170 calories total for a screwdriver.
- Cranberry Juice: Even worse. Most "cranberry juice" at bars is a "cocktail" blend with massive amounts of high-fructose corn syrup.
If you’re genuinely concerned about how many calories is a shot of vodka, stick to soda water (the plain stuff) or drink it on the rocks with a squeeze of lime. The lime adds maybe 1 calorie. It’s a fair trade for the flavor.
The Different Brands: Does Price Matter?
Does expensive vodka have fewer calories? Short answer: No.
Whether you’re drinking Grey Goose, Belvedere, or the plastic bottle from the bottom shelf, the calorie count is dictated by the alcohol by volume (ABV). Most vodka is 40% ABV.

The difference in price comes down to the quality of the base grain, the number of times it was distilled, and the filtration process. Higher-end vodkas are filtered through everything from charcoal to diamonds to remove "congeners"—the impurities that often lead to worse hangovers. So, while a $50 bottle of vodka won't make you thinner than a $10 bottle, it might make your Saturday morning a lot more bearable.
The Science of Ethanol Metabolism
Let’s nerd out for a second. When you ingest ethanol, the enzyme alcohol dehydrogenase (ADH) starts breaking it down in your liver. It turns into acetaldehyde. This stuff is actually pretty toxic and is responsible for that "I'm never drinking again" feeling.
Then, another enzyme called ALDH breaks it down into acetate. Finally, acetate is broken down into water and carbon dioxide. During this entire process, your body is producing NADH. High levels of NADH signal to your body that it has plenty of energy, so it stops breaking down fatty acids.
Basically, drinking vodka tells your body: "Stop burning fat, we’ve got this alcohol to deal with."
Practical Strategy for the Health-Conscious Drinker
If you are tracking your macros or trying to lose weight, you don't necessarily have to give up drinking. You just have to be smart.
First, hydrate. Drink a full glass of water for every shot of vodka. It slows you down and keeps you from getting dehydrated. Second, watch the "drunk munchies." Most people don't gain weight from the vodka itself; they gain weight from the 2:00 AM taco run. That’s the real calorie trap.

Third, consider the "hangover effect" on your fitness. If a few shots of vodka lead to you skipping your workout the next day and ordering a greasy breakfast, the "cost" of those calories just tripled.
Summary of What You Need to Know
If you are looking for the bottom line on how many calories is a shot of vodka, keep these points in your back pocket:
- A standard 1.5 oz shot of 80-proof vodka is 97 calories.
- A 100-proof shot jumps to 124 calories.
- Flavorings can add sugar, so look for "infused" rather than "liqueur" styles.
- Soda water and citrus are your best friends; tonic and juice are your enemies.
- The calories in alcohol stop your body from burning fat for several hours.
Better Choices for Your Next Night Out
Instead of a sugary cocktail, try a "NorCal Margarita" style drink but with vodka. Use a shot of vodka, plenty of soda water, and the juice of half a lime. It’s crisp, it’s refreshing, and it keeps the calorie count under 100.
Another pro tip: sip, don't shoot. When you shoot vodka, the blood alcohol level spikes rapidly, which can lead to poorer decision-making (like ordering that second basket of fries). Sipping it over ice allows you to enjoy the drink longer without the metabolic roller coaster.
Managing your intake is about more than just a single number. It’s about understanding the ripple effect that one shot has on your habits, your sleep, and your metabolism the following day. Stick to the basics, watch your mixers, and you can keep your goals on track without living like a hermit.
Actionable Next Steps:
- Check the bottle in your cabinet for the "proof." If it’s higher than 80, adjust your calorie tracking upward by about 25%.
- Switch your next mixer from tonic to club soda to instantly save 80–100 calories per glass.
- Eat a high-protein meal before you start drinking to slow alcohol absorption and prevent the "metabolic stall" from triggering intense hunger later.
