Yes, a vodka soda is one of the lowest-calorie cocktails you can order. A standard vodka soda made with 1.5 ounces of 80-proof vodka and plain club soda contains roughly 97 calories, with every single one of those calories coming from the alcohol itself. Club soda adds zero calories and zero sugar, making this a reliably lean choice at the bar.
Where the Calories Come From
Alcohol contains 7 calories per gram, which puts it between carbohydrates (4 calories per gram) and fat (9 calories per gram). A standard 1.5-ounce pour of 80-proof vodka delivers about 97 calories. Plain vodka has no sugar, no carbs, no fat, and no protein. The calories are entirely from the ethanol.
Club soda is just carbonated water with a small amount of added minerals like sodium bicarbonate. It contributes nothing caloric to the drink. So a vodka soda’s calorie count is essentially the calorie count of the vodka alone, plus whatever you squeeze on top (a lime wedge adds about 1 calorie).
Vodka Soda vs. Other Drinks
At roughly 97 calories, a vodka soda compares favorably to almost every other alcoholic drink. A 5-ounce glass of wine typically runs 120 to 130 calories. A 12-ounce regular beer lands around 150 calories, and craft beers or IPAs can climb well past 200. Even a light beer, often marketed as the low-calorie option, comes in around 100 calories for 12 ounces, which is nearly the same as a vodka soda but with less alcohol per serving.
Cocktails made with juice, simple syrup, or cream are in a different league entirely. A margarita can easily hit 275 calories. A piña colada pushes past 400. The vodka soda’s advantage is its simplicity: spirit plus water, nothing else.
The Tonic Water Trap
One of the most common mistakes is confusing a vodka soda with a vodka tonic. They look identical in the glass, but the calorie difference is significant. A 12-ounce serving of tonic water contains 124 calories and 32 grams of sugar. That’s nearly as much sugar as a can of cola. Swapping tonic for club soda in your drink effectively doubles the calorie count.
If you’re ordering at a bar, be specific. Ask for vodka with club soda or soda water. “Vodka soda” is generally understood correctly, but if your bartender reaches for the tonic gun, speak up.
Do Flavored Vodkas Change the Math?
Not as much as you’d expect. Most major flavored vodkas from large brands land in the same calorie range as plain vodka, sometimes even slightly lower. Ciroc Coconut Vodka clocks in at about 94 calories per shot. Smirnoff Citrus comes in at 87. Even novelty options like bacon-flavored vodka only add a few calories, reaching about 105 per shot.
Some brands market “light” flavored vodkas that dip lower by reducing the alcohol content. SkinnyGirl’s naturally flavored vodkas contain about 76 calories per serving, and Smirnoff’s Light Lemon Sorbet sits at 78. These save you 20 or so calories per drink because they’re lower proof, not because of any special formulation.
The real risk with flavored vodkas isn’t the vodka itself. It’s the tendency to pair them with sugary mixers like cranberry juice or lemonade, which can add 100 or more calories per drink. A flavored vodka with club soda keeps the calorie count low. A flavored vodka with ginger beer or juice does not.
Why “Low Calorie” Doesn’t Mean “Free Pass”
Alcohol calories are what nutritionists call “empty.” They provide energy your body can use as fuel but deliver zero vitamins, minerals, protein, or fiber. Gram for gram, alcohol is almost twice as calorie-dense as carbohydrates or protein.
Your body also handles alcohol differently than food. When you drink, your liver prioritizes breaking down the ethanol because it treats alcohol as a mild toxin. While it’s busy doing that, your normal fat-burning processes slow down. The liver’s chemical environment shifts in a way that actively promotes fat storage and blocks the transport of fatty acids into the parts of your cells that would normally burn them for energy. This isn’t permanent, but it means the calories you eat alongside your drinks are more likely to be stored rather than used.
There’s also the appetite factor. Alcohol doesn’t make you feel full the way food does. You’re taking in calories without any of the satiety signals that tell your brain you’ve eaten. Studies consistently show that people tend to eat more, and make worse food choices, when they’re drinking. The vodka soda itself may be 97 calories, but the late-night pizza it leads to is a different story.
How to Keep Your Vodka Soda Truly Low Calorie
Stick with 80-proof plain or flavored vodka and genuine club soda or seltzer. Add a squeeze of fresh lime, lemon, or even a few muddled cucumber slices for flavor without meaningful calories. Avoid premixed “vodka soda” cans without checking the label first, as some brands add sugar or fruit juice that quietly raise the calorie count.
Watch your pour size. The 97-calorie figure assumes a standard 1.5-ounce shot. A generous home pour or a double at the bar pushes you closer to 200 calories per glass. If you’re making drinks at home, a jigger keeps things honest. At a bar, ordering a single tall (more soda, same amount of vodka) gives you a longer-lasting drink without extra calories.
