A 1.5-oz pour of 80-proof vodka topped with 4–6 oz soda water lands around 96–100 calories, with zero sugar and zero carbs.
Vodka Soda Calories & More
Vodka soda is simple: vodka, soda water, ice, and usually a citrus wedge. The calories come almost entirely from the alcohol. Plain soda water has no calories, no sugar, and no carbs. That’s why people who want a lighter mixed drink often pick this highball over sweet cocktails.
The standard bar pour is 1.5 ounces. When that pour is 80-proof vodka, you’re looking at about 96–97 calories for the alcohol itself, and still 0 from the soda. MedlinePlus lists 97 calories for a 1.5-oz shot of 80-proof spirits, and MyFoodData’s club soda entry shows 0 calories for the mixer. That simple combo explains why a vodka soda stays lean while a rum-and-cola or a gin and tonic does not.
Calories In Vodka Soda By Pour Size
Need the math at a glance? Use this chart for common builds. Values assume plain soda water and no syrups.
| Build | ABV/Proof | Calories |
|---|---|---|
| 1.0 oz vodka + soda | 40% / 80-proof | ≈ 64 |
| 1.25 oz vodka + soda | 40% / 80-proof | ≈ 80 |
| 1.5 oz vodka + soda (standard) | 40% / 80-proof | ≈ 96–97 |
| 2.0 oz vodka + soda (“double”) | 40% / 80-proof | ≈ 128–130 |
| 1.5 oz vodka + soda | 45% / 90-proof | ≈ 110 |
| 1.5 oz vodka + soda | 50% / 100-proof | ≈ 123–124 |
| “Tall” drink (1.5 oz vodka, 8–10 oz soda) | 40% / 80-proof | ≈ 96–97 |
| “Short” drink (2 oz vodka, 2–3 oz soda) | 40% / 80-proof | ≈ 128–130 |
What Counts As A Standard Pour
Bars commonly use a 1.5-oz jigger for a house pour. That size equals one U.S. standard drink of distilled spirits. If your bartender free-pours a heavier shot or you’re using a larger home measure, the calories go up in lockstep.
Why Proof Changes The Math
Proof is just alcohol strength. More alcohol means more calories in the same volume. A 100-proof shot has more alcohol than an 80-proof shot, so the calorie line climbs even when the glass looks identical.
Where The Calories Come From
Alcohol delivers about 7 calories per gram. That’s why spirits deliver energy even when there’s no sugar in the glass. Soda water doesn’t add anything, which is the whole appeal of a vodka soda when you want a leaner sip.
Club Soda, Seltzer, Or Tonic?
These names get swapped in conversation, but they’re not the same. Club soda and plain seltzer are carbonated water. Both are calorie-free. Tonic water contains sugar and will add calories, even in a small splash. If you like the quinine bite, keep the pour tiny or choose a diet tonic.
What About Flavored Sparkling Waters?
Unsweetened lime or grapefruit seltzers still clock in at 0 calories. Canned “sparkling cocktails” are different because the alcohol is already in the can and many include juice or sweetener. Always check the can if you’re counting.
Calorie Math You Can Trust
If you’re curious how those chart numbers come together, here’s a quick guide. Ethanol weighs a bit less than water. A standard 1.5-oz shot of 80-proof spirit contains about 0.6 fl oz of pure alcohol. That’s around 14 grams of alcohol. Since alcohol carries roughly 7 calories per gram, the arithmetic lands in the 95–100 calorie window. Swap in a stronger proof and the grams of alcohol rise, so the total climbs in step.
Worked Examples
One ounce of 80-proof vodka is close to 64 calories. A double pour of 2 ounces lands near 128–130 calories. Switch to 100-proof at the same 1.5-oz pour and you’re near 124 calories. The soda water doesn’t change the count, whether you add 3 ounces or 10.
How To Keep A Vodka Soda Lean
You don’t need to baby the drink, but small choices help. Use a measured jigger at home. Order a “single tall” at the bar so you get more soda in a bigger glass with the same shot. Pick citrus and herbs over syrup when you want flavor.
Smart Garnishes And Add-Ins
A squeeze of lemon or lime adds brightness for a few calories. A grapefruit peel, cucumber ribbon, or mint sprig adds aroma with no energy cost. Bitters are concentrated, so a dash or two adds only a sliver of calories. Watch out for heavy hands with simple syrup or liqueurs.
Calories For Popular Add-Ins
Numbers below are per ounce unless noted. Toss in less and you’ll trim the count.
| Ingredient | Calories/oz | Notes |
|---|---|---|
| Fresh lime or lemon juice | ≈ 7–9 | 1–2 wedges is under 5 calories |
| Grapefruit juice (unsweetened) | ≈ 12–13 | Try a 0.5-oz splash |
| Cranberry juice cocktail | ≈ 16–17 | Sweetened; keep it light |
| Simple syrup (1:1) | ≈ 50–55 | Equal parts sugar and water |
| Diet tonic water | 0 | Flavored but unsweetened |
| Tonic water | ≈ 10–11 | Sugar-sweetened; count your splash |
| Orange bitters | ≈ 5 (per tsp) | Big flavor, tiny dose |
| Cucumber, herbs, peels | 0 | Aroma without calories |
Ordering Tips That Save Calories
Say “vodka soda with fresh lime” to make your build clear. If you like a bigger glass, ask for it tall, not double. Skip pre-mixed sour and “lime” guns; those usually add sugar. If tonic is your go-to, ask for diet tonic or cut it fifty-fifty with soda water.
Home Bartending Tips
Grab a 1- and 2-ounce jigger so your home pours are consistent. Keep chilled seltzer handy; colder bubbles feel crisper and make a drink taste brighter. Use big ice cubes to slow dilution. Pre-slice citrus so you can squeeze a wedge into the glass instead of reaching for syrup.
Flavor Ideas With Minimal Calories
Build a theme with herbs and peels. Lime with mint, lemon with thyme, or grapefruit with rosemary will make a simple vodka soda feel polished. A pinch of flaky salt on the rim wakes up the citrus and keeps the drink from tasting flat.
Bar Menu Terms That Change Calories
Menus use shorthand. “Neat” is spirit with no ice; “rocks” is spirit over ice. Neither includes soda, so both will deliver just the alcohol calories. “Up” usually means chilled and strained into a stemmed glass, still without soda. “Tall” keeps the shot the same and adds more soda in a larger glass. “Double” means more alcohol, which raises the count quickly.
Does Vodka Brand Matter?
For calories, brand isn’t the driver. Proof is. Most unflavored vodkas sit at 80 proof, some at 90, and a few at 100. Flavored vodkas can be the same proof, yet some lines include a touch of sugar. If you’re aiming for the leanest pour, pick an unflavored 80-proof bottle and add flavor with citrus and herbs in the glass.
Is A Vodka Soda Low-Carb?
Yes. Pure spirits don’t contain carbohydrate, and soda water has none either. That’s why a vodka soda fits low-carb patterns when portion sizes stay reasonable. The carb count changes when mixers with sugar enter the picture, like juice blends, sour mix, or regular tonic.
Troubleshooting Your Build
Drink feels bland? Add more ice and a fresh citrus squeeze. Too boozy? Top with extra soda and give it a gentle stir. Prefer more bite? Add a skinny lemon wheel or a grapefruit peel and skip sweeteners.
When The Calories Creep Up
Two moves push the count higher: stronger vodka or sweet mixers. A double pour adds another 32–34 calories per extra 0.5 oz of 80-proof spirit. Sugar syrups stack up fast too. Even a single ounce of simple syrup can turn a light highball into a dessert drink.
Vodka Soda Vs. Other Simple Highballs
Gin and soda, tequila soda, or whiskey and soda follow the same pattern. The proof of the spirit dictates the calories; soda water keeps the rest at zero. Swap soda for cola, ginger ale, or tonic and the picture changes because those mixers bring sugar.
Quick Tips For Tonight
- Base count: a 1.5-oz 80-proof vodka soda sits near 96–100 calories for most builds.
- Club soda and plain seltzer: 0 calories; tonic water adds sugar.
- Proof and pour size drive the numbers; measure when you can.
- For flavor without a big calorie bump, use citrus, herbs, peels, and a tall glass.
Sample Low-Calorie Vodka Soda Builds
Want ideas you can mix tonight without chasing numbers? Try these easy combos. Each stays under 120 calories when you pour 1.5 oz of 80-proof vodka and top with soda water.
- Lime Highball: 1.5 oz vodka, squeeze of lime, 6–8 oz soda, tall glass with lots of ice.
- Grapefruit Peel & Salt: Express a grapefruit peel over the glass, tiny pinch of flaky salt on the rim, top with 6–8 oz soda.
- Cucumber Mint: Thin cucumber ribbons and a mint sprig, 1.5 oz vodka, 6 oz soda; stir gently.
- Lemon Thyme: Lemon wheel and a small thyme sprig, 1.5 oz vodka, 7–8 oz soda.
Sodium And Bubbles
Club soda can contain a little sodium from mineral additions, while plain seltzer usually has none. That doesn’t touch the calorie count, but some people prefer seltzer for a lighter taste. If you enjoy club soda’s minerality, go for it; if you want the cleanest profile, reach for unflavored seltzer. Either way, the calories stay the same because the mixer is still just carbonated water.
One More Handy Rule
If the drink tastes sweet, you added calories. If it tastes bright and crisp, you’re probably still near the base count from the vodka alone. Check the proof on the bottle, measure your shot, and use plenty of soda and ice. That trio keeps the flavor high and the numbers steady.
