Vodka is one of the most popular spirits worldwide, yet its nutritional profile is often misunderstood. While vodka is essentially a distilled product with no carbohydrates, fat, or protein, it does contain trace amounts of minerals, including potassium. This calculator helps you estimate the potassium content in your vodka drink based on the volume you consume and the proof (alcohol percentage) of the spirit.
Whether you are tracking your daily potassium intake for kidney health, managing blood pressure, or simply curious about the micronutrient content of your favorite cocktail, this tool provides a quick and reliable estimate. Simply enter the amount of vodka you plan to drink, select the proof, and the calculator will compute the potassium in milligrams, along with the corresponding calories and alcohol content.
Use this calculator alongside other nutrition tools to get a complete picture of your diet. It is especially useful for those following a low-potassium diet or monitoring their electrolyte balance.

Step-by-step
How to Use This Tool
Using the vodka potassium calculator is straightforward. Start by entering the volume of vodka you plan to consume. You can choose between milliliters (ml), fluid ounces (fl oz), or shots (where one shot equals 1.5 fl oz). Next, select the proof of your vodka from the dropdown. The proof is twice the alcohol by volume (ABV), so 80 proof equals 40% ABV, 100 proof equals 50% ABV, and so on. If you are unsure, check the label on the bottle — most standard vodkas are 80 proof, but higher-proof varieties are common for mixing or sipping.
After clicking the Calculate button, the tool displays the estimated potassium content in milligrams, along with the total calories and the volume of pure alcohol and water in your drink. The step-by-step breakdown shows the exact calculations used, so you can verify the numbers or adjust them for your own tracking.
For quick reference, the preset buttons let you instantly fill in common serving sizes: a single shot (44 ml), a double shot (89 ml), or a standard cocktail pour (5 fl oz). This is handy when you are estimating a drink at a bar or a party.
How It Works
Vodka is a distilled spirit, which means it is primarily a mixture of ethanol and water. During distillation, most minerals and other compounds are removed, leaving only trace amounts. According to the USDA FoodData Central, an 80-proof vodka contains approximately 1 milligram of potassium per 100 milliliters. This is an extremely small amount — for context, a medium banana provides about 422 mg of potassium, which is over 400,000 times more per serving.
The calculator uses this baseline value and scales it linearly with volume. So, for 50 ml of vodka, the potassium is 0.5 mg; for 250 ml, it is 2.5 mg. The calorie calculation is based on the alcohol content: each gram of pure alcohol provides about 7 calories. Since the density of ethanol is 0.789 g/ml, the formula becomes: calories = volume (ml) × (ABV/100) × 0.789 × 7. This gives a close approximation, though actual calorie counts can vary slightly due to other trace compounds.
The water content is simply the total volume minus the alcohol volume. This is useful for understanding hydration, though it is important to note that alcohol has a diuretic effect, so the net hydration impact is negative.
Worked Examples
Example 1: Standard shot
You pour a 44 ml shot of 80-proof vodka. The calculator computes:
Potassium = 44 × 0.001 = 0.044 mg
Alcohol = 44 × 0.40 = 17.6 ml
Calories = 17.6 × 0.789 × 7 ≈ 97 kcal
Water = 44 − 17.6 = 26.4 ml
Example 2: Cocktail with 2 fl oz vodka
2 fl oz equals 59.15 ml. If you use 100-proof vodka (50% ABV):
Potassium = 59.15 × 0.001 = 0.059 mg
Alcohol = 59.15 × 0.50 = 29.57 ml
Calories = 29.57 × 0.789 × 7 ≈ 163 kcal
Water = 59.15 − 29.57 = 29.57 ml
Tips & Best Practices
- Check your bottle: Always verify the proof on the label. Many flavored vodkas have added sugars and other ingredients that can alter the potassium and calorie content.
- Use standard measurements: A standard shot in the US is 1.5 fl oz (44 ml), but in some countries it can be 1 oz or 2 oz. Adjust the volume accordingly.
- Consider mixers: If you are mixing vodka with juice or soda, remember that the mixer adds its own potassium and calories. Use the cocktail calorie calculator to get a full picture.
- Track your intake: For those on a low-potassium diet, the amount in vodka is negligible, but the alcohol itself can affect kidney function and blood pressure. Always consult your healthcare provider.
Factors Affecting Accuracy
The potassium value used in this calculator is an average from USDA data. Actual levels can vary slightly between brands due to differences in water source and distillation processes. However, the variation is so small that it is unlikely to have any meaningful impact on your dietary tracking.
Calorie estimates are also approximate. The 7 kcal per gram of alcohol is a standard figure, but the actual energy yield can vary slightly. Additionally, if you drink vodka on the rocks or with a splash of water, the total volume changes, which affects the calculations. Always measure your pour accurately for the best results.
Frequently Asked Questions
Does vodka contain any potassium? Yes, but only in trace amounts. A typical serving of vodka (44 ml) contains less than 0.1 mg of potassium, which is negligible compared to the recommended daily intake of 3,500–4,700 mg for adults.
Is vodka keto-friendly? Yes, pure vodka contains no carbohydrates, so it fits into a ketogenic diet. However, the calories from alcohol still count, and excessive consumption can hinder weight loss.
Can I use this calculator for other spirits? The potassium content is similar for most distilled spirits like gin, rum, and whiskey, but the calorie content varies with proof. For a more general tool, see the sports nutrition calculator or the protein calculator.
Why is the potassium so low? Distillation removes almost all minerals. The small amount that remains comes from the water used to dilute the spirit to bottling strength.
