Quick Answer: Calories in a Vodka Diet Coke by Standard Serving
Calories per Shot (1.5 oz) with Diet Coke
A standard serving of vodka (1.5 oz or 45 ml, 80 proof) mixed with Diet Coke (6 oz or 180 ml) contains approximately 97-100 calories. Nearly all calories come from the vodka; Diet Coke contributes virtually zero calories owing to its use of aspartame or similar nonnutritive sweeteners.[1]
Common Glass Sizes and Total Calories
- Single (1.5 oz vodka + 6 oz Diet Coke): 98 calories
- Double (3 oz vodka + 12 oz Diet Coke): 196 calories
- Tall glass (1.5 oz vodka + 8 oz Diet Coke): 99 calories
Table: Vodka Diet Coke Calories by Serving
| Serving Size | Vodka (80 proof) | Diet Coke | Total Calories |
|---|---|---|---|
| Single (1.5 oz + 6 oz) | 97 | ~1 | 98 |
| Double (3 oz + 12 oz) | 194 | ~2 | 196 |
| Tall (1.5 oz + 8 oz) | 97 | ~2 | 99 |
Top 5 Factors Affecting Vodka Diet Coke Calorie Count
Vodka Brand and Proof Differences
- Calorie content increases with alcohol proof:
70 proof (35%): 85 calories per 1.5 oz
80 proof (40%): 97 calories per 1.5 oz
90 proof (45%): 110 calories per 1.5 oz
100 proof (50%): 124 calories per 1.5 oz - Major brands such as Smirnoff, Absolut, and Tito’s use 80 proof as the standard, making them nutritionally similar for calorie content.[1]
Glass Size and Pour Amount
- Larger pours or “doubles” can quickly double calorie count.
- Standard bar servings typically use 1.5 oz vodka per drink, but home or club pours may vary.
Mixer Choices: Diet Coke Brands & Zero-Cal Alternatives
- Diet Coke, Diet Pepsi, and store-brand diet colas all contribute zero or negligible calories.
- Sugar-free tonic or seltzer: ideal for zero-calorie mixing.
Add-Ins: Ice, Garnish, and Flavor Enhancers
- Ice: Adds bulk but no calories.
- Lime wedges/lemon: Minimal calories (1–2 per wedge).
- Sugar-free flavor drops: Negligible calorie contribution.
Pre-mixed Vodka Diet Coke vs Homemade
- RTD (Ready-to-Drink) vodka Diet Coke may use lower-alcohol spirits and have calorie ranges from ~62–72 per 250 ml can due to variable vodka content.
- Homemade versions may be stronger and higher in calories if poured generously.

Is Vodka Diet Coke Really Zero Calorie? The Science Explained
Breakdown of Alcohol Calories vs Mixer Calories
- All calories in a vodka Diet Coke come from the ethanol in vodka (7 calories per gram).
- Diet Coke, using aspartame or sucralose, adds practically zero extra calories, even in large amounts.
Diet Coke Ingredients & Calorie Myths
- Diet Coke contains water, caramel color, aspartame, phosphoric acid, and flavoring. None contribute significant calories.
- Extensive studies show aspartame does not provide energy, alter blood sugar, or add “hidden” calories when used as directed.[4]
Aspartame, Sweeteners, and Health Considerations (2026 update)
- Aspartame is classified as “possibly carcinogenic” (Group 2B) per WHO/IARC, but current levels in Diet Coke are considered safe by food safety authorities.[2]
- No clinical data shows calorie changes when aspartame and vodka are combined; aspartame’s possible effect on appetite and metabolism remains controversial but does not impact raw calorie count.[6]
