A 1.5-oz pour of 80-proof vodka with soda water has about 97 calories; soda water is calorie-free.
Vodka with soda water is the go-to skinny highball. No syrups, no sugar—just clear spirit topped with bubbles. Still, the exact number on the glass depends on how much vodka you pour and the proof you choose.
Here’s the straight math for a bar-style pour, plus quick ways to tweak calories without losing flavor. All numbers below use standard U.S. measures and common proofs.
Start with the basics. These totals assume plain soda water (club soda or sparkling water) adds zero calories, which is why this mix stays lean.
| Drink Build | Proof (ABV) | Calories (approx) |
|---|---|---|
| 1 oz vodka + soda | 80-proof (40% ABV) | ≈65 |
| 1.25 oz vodka + soda | 80-proof (40% ABV) | ≈81 |
| 1.5 oz vodka + soda | 80-proof (40% ABV) | ≈97 |
| 2 oz vodka + soda | 80-proof (40% ABV) | ≈131 |
| 1.5 oz vodka + soda | 70-proof (35% ABV) | ≈86 |
| 1.5 oz vodka + soda | 90-proof (45% ABV) | ≈110 |
| 1.5 oz vodka + soda | 100-proof (50% ABV) | ≈123 |
| 2 oz vodka + soda | 70-proof (35% ABV) | ≈114 |
| 2 oz vodka + soda | 100-proof (50% ABV) | ≈163 |
Vodka And Soda Water Calories: By Proof And Pour
Alcohol supplies the calories in this drink. The bubbles don’t. A 1.5-oz shot of 80-proof vodka lands near the 97–100 range per drink. Smaller or larger pours scale that up or down. Higher proof raises the total too.
To keep labels straight: proof is twice the alcohol by volume (ABV). So 80-proof is 40% ABV, 100-proof is 50% ABV. Public health guidance treats a 1.5-oz 80-proof pour as one standard drink that contains 14 grams of pure alcohol—see the standard drink sizes page for details. That single number explains why a classic vodka-soda usually clocks in around the high-90s for calories.
If your home jigger is 2 oz or your bottle is 90- or 100-proof, the math changes. The table above shows typical builds so you can spot the difference at a glance.
What Actually Adds Calories Here
Vodka, like other distilled spirits, brings calories from alcohol, not sugar. Unflavored vodka has 0 g sugar and 0 g carbs. Soda water, club soda, and plain sparkling water contribute 0 calories as well. The only swing factor is the amount and proof of the spirit.
Tonic water isn’t the same as soda water. Tonic carries sugar, so swapping soda for tonic can add dozens of calories in one glass. MedlinePlus keeps a quick table of common drink calories; it lists a 1.5-oz shot of 80-proof vodka at about 97 calories. That’s the number used in the mixer comparison below.
Ways To Keep Your Vodka Soda Lean
Use a measured pour. If weight loss is on your mind, stick to a 1-oz or 1.25-oz shot instead of a heavy 2-oz free-pour. That single change trims 30–35 calories while the glass still looks full once you add ice and bubbles.
Pick lower proof. A 70-proof bottle shaves a few calories per drink compared with the same pour of 90- or 100-proof. You’ll see the spread in the chart below.
Pile on citrus and aroma. Big wedges of lime or lemon, a few dashes of bitters, a strip of cucumber, or a splash of chilled herbal tea add pop with essentially no calories.
Choose the right bubbles. Club soda, seltzer, and still mineral water are all calorie-free. Diet tonic is fine too if you like quinine’s bite without the sugar.
Glass Size, Ice, And Dilution
A tall Collins glass with lots of ice stretches the drink while keeping the vodka dose steady. As the ice melts, the total liquid increases but the calorie count doesn’t budge. That’s the beauty of a spirit-plus-soda build.
If you’re counting, top with 4–6 oz of soda water. That range keeps flavor bright and the fizz lively while leaving space for garnish.
Calories Versus Common Mixers
This is where vodka-soda shines. Sweet mixers shift the numbers fast. The table below uses a 1.5-oz shot of 80-proof vodka (about 97 calories) and 6 oz of each mixer. Brands vary, so treat these as ballpark values.
| Mixer | Calories From Mixer | Total Drink Calories |
|---|---|---|
| Soda water / seltzer | ≈0 | ≈97 |
| Diet tonic | ≈0 | ≈97 |
| Tonic water | ≈65 | ≈162 |
| Cola | ≈78 | ≈175 |
| Ginger beer | ≈96 | ≈193 |
| Orange juice | ≈84 | ≈181 |
| Cranberry cocktail | ≈105 | ≈202 |
| Lemonade | ≈90 | ≈187 |
Flavored Seltzers, Hard Seltzers, And Canned Vodka Sodas
Flavored seltzer water is usually unsweetened and still adds 0 calories. That’s perfect with vodka. Hard seltzers are different: they contain alcohol in the can, so their calories come from the alcohol inside, commonly 90–130 per 12 oz. Canned “vodka soda” products work the same way; check the label for ABV and serving size.
Simple Ordering Tips At A Bar
Ask for vodka soda with lots of ice and a double lime. If you want fewer calories, request a 1-oz pour. If you prefer a little sweetness, add a splash of diet tonic, diet ginger ale, or a squeeze of fresh citrus instead of juice.
Practical Wrap-Up
Vodka plus soda water stays lean because only the spirit supplies energy. A standard 1.5-oz pour of 80-proof comes in near 97 calories; soda water adds none. Change the proof or the pour, and the total moves predictably. Keep the bubbles, use a jigger, and garnish big—that’s the easy way to keep flavor high and calories steady.
Soda Water Vs. Seltzer Vs. Club Soda Vs. Tonic
Soda water and seltzer are both carbonated water. Club soda is the same idea with minerals added for bite and bubbles. All three are calorie-free. Tonic water is different: it’s sweetened and flavored with quinine, so it carries sugar and calories.
If you like a mineral note, reach for club soda. If you want a softer sparkle, pick seltzer. For a dry finish, plain sparkling mineral water tastes great with fresh lime.
Does Flavored Vodka Change Calories?
Most plain vodkas sit in the same calorie band at a given proof. Flavored vodkas vary. Unflavored means no sugar; some flavored labels stay unsweetened, while others add a touch of sugar. Read the back label. If sugar is listed, the drink will land a bit higher than the table for the same proof.
How To Estimate Calories On The Fly
Here’s a handy estimate you can use anywhere. One standard 1.5-oz pour of 80-proof vodka is about 97–100 calories. Each additional half-ounce adds around 30–35 calories at 80-proof. Higher proof adds a little more per step.
Quick examples: a 1-oz 80-proof pour is near 65. A 2-oz 80-proof pour lands near 130. Swap the bottle for 100-proof and a 1.5-oz pour rises to about 123. The first chart above shows more cases side by side.
Common Mistakes That Spike Calories
Ordering a vodka tonic by accident. Tonic looks like soda water but brings sugar. If you want the lean option, say “vodka soda.”
Letting the free-pour run long. A heavy hand turns one drink into one-and-a-half. Ask for a measured pour or a single shot.
Adding fruit juice instead of fruit. A squeeze of lemon or lime is free in calorie terms. Four ounces of juice isn’t.
Choosing sweet syrups out of habit. Simple syrup and liqueurs stack up calories quickly, even in small amounts.
If You’re Tracking Macros
Alcohol calories don’t count as carbs, fat, or protein on nutrition labels, yet they still count toward your daily total. Many tracking apps log vodka as 97 calories per 1.5-oz shot at 80-proof and 0 g carbs. That lines up with the tables here.
To reduce carbs without changing calories, swap sweet mixers for soda water or diet mixers. To reduce calories, downsize the pour or pick a lower proof. Both tactics keep the flavor profile the same.
Easy Low-Cal Builds At Home
Here are two templates you can make without a recipe card. Grab a jigger and a tall glass. They keep calories steady while giving you wiggle room on flavor.
Bright Lime Highball
1 to 1.5 oz vodka • Ice • 5 to 6 oz soda water • 2 big lime wedges. Squeeze one wedge in the glass, build over ice, top with soda, then squeeze the second wedge across the top.
Cucumber-Mint Cooler
1 oz vodka • Ice • 6 oz soda water • 1 ribbon of cucumber • 3 mint leaves. Smack the mint once in your palm, drop everything in the glass, top with soda, give it a gentle stir.
Reading Proof And ABV On Labels
Vodka labels show alcohol by volume as a percent. Some also list proof. Double the ABV to get proof. Examples: 40% ABV equals 80-proof; 35% equals 70-proof; 50% equals 100-proof.
Proof affects calories because it changes how much pure alcohol sits in the same volume. A lower-proof vodka gives the same flavor once mixed tall, while saving a few calories per glass.
A Quick Note On Sodium
Club soda can include sodium from added minerals; seltzer usually has little to none. If you track sodium, swap club soda for plain seltzer or sparkling mineral water. The calorie math stays the same.
What About Bitters Or A Splash Of Juice?
Two or three dashes of aromatic bitters add just a trace of calories—think single-digit numbers. A one-ounce splash of citrus juice adds roughly 10–15 calories while brightening the drink. Use small splashes and you’ll still keep totals near the classic range.
