Pomegranates are prized for their vibrant arils and rich antioxidant profile, but they also pack a significant potassium punch — essential for heart function, muscle contraction, and fluid balance. This calculator helps you quickly determine the potassium content in any amount of pomegranate, whether you're tracking micronutrients for a diet plan, managing kidney health, or simply curious about your daily intake.
Simply enter the weight of pomegranate (in grams or ounces) and the calculator will estimate the potassium in milligrams, based on USDA data for raw pomegranate arils. You can also adjust for whole fruit vs. arils only. Perfect for nutritionists, fitness enthusiasts, and anyone monitoring their potassium levels.
🥜 Pomegranate Potassium Calculator
How to Use This Tool
Using the Pomegranate Potassium Calculator is straightforward. Enter the weight of your pomegranate (either in grams or ounces) using the number input. Then select whether you are measuring arils only (the edible seeds) or the whole fruit (including the inedible rind). The calculator automatically adjusts for the edible portion — whole pomegranates yield roughly 55% edible arils by weight. Click the blue Calculate button to see the estimated potassium content in milligrams, along with a breakdown of the weight used and the per-100g equivalent. Use the preset buttons (100 g, 150 g, 200 g, 3.5 oz, 5 oz) for quick common portions. The Reset button clears all fields and results.
Formula Explained
The calculation is based on USDA National Nutrient Database data for raw pomegranate arils. The standard potassium value is 236 mg per 100 grams of arils. The formula is:
Potassium (mg) = (Weight in grams / 100) × 236
If you select "Whole fruit," the calculator multiplies the result by 0.55 (55% edible portion) to account for the rind and membrane that are not consumed. For ounce inputs, the weight is first converted to grams using the conversion factor 1 oz = 28.3495 g.
Worked Examples
Potassium = (150 / 100) × 236 = 354 mg.
This is roughly 7.5% of the Daily Value.
Edible weight = 200 × 0.55 = 110 g.
Potassium = (110 / 100) × 236 = 259.6 mg.
This is about 5.5% of the Daily Value.
Convert to grams: 5 × 28.3495 = 141.75 g.
Potassium = (141.75 / 100) × 236 = 334.5 mg.
This is about 7.1% of the Daily Value.
Factors Affecting Accuracy
While the USDA value of 236 mg per 100 g is a reliable average, actual potassium content can vary due to several factors:
- Variety: Different pomegranate cultivars (e.g., Wonderful, Hicaz, Ganesh) may have slightly different mineral profiles.
- Ripeness: Potassium levels can increase slightly as the fruit ripens.
- Growing conditions: Soil potassium content, irrigation, and fertilization practices affect the fruit's mineral uptake.
- Measurement method: Weighing accuracy and whether you include small bits of membrane with the arils will affect the result.
For clinical or medical purposes, always consult a registered dietitian or use laboratory analysis for precise values.
Frequently Asked Questions
Q: Is pomegranate high in potassium?
A: Yes, pomegranate is considered a good source of potassium. A 100 g serving of arils provides 236 mg, which is about 5% of the Daily Value. For comparison, a banana (118 g) provides about 422 mg of potassium.
Q: Can I use this calculator for pomegranate juice?
A: No, this calculator is designed for whole arils or whole fruit. Pomegranate juice has a different potassium concentration (typically around 200-250 mg per 100 ml, depending on the brand and whether it's diluted). For juice, look for a separate tool or check the nutrition label.
Q: How does pomegranate potassium compare to other fruits?
A: Pomegranate is moderate in potassium. For reference, 100 g of banana has about 358 mg, orange has 181 mg, apple has 107 mg, and avocado has 485 mg. Pomegranate sits in the middle range.
Q: Is this tool suitable for people with kidney disease?
A: This calculator provides estimates for general nutrition tracking. If you have chronic kidney disease or are on a potassium-restricted diet, consult your healthcare provider for personalized guidance. The values here are based on average data and may not be precise enough for medical decisions.

Real-World Applications
Tracking potassium intake is important for athletes, individuals with hypertension, and those on specific dietary plans like the DASH diet (Dietary Approaches to Stop Hypertension). Pomegranate can be a flavorful addition to salads, smoothies, yogurt, or eaten on its own. Use this calculator to log your potassium intake from pomegranate in your daily food diary or nutrition app. For more detailed dietary planning, you may also find our Pomegranate Sodium Calculator useful for tracking both minerals together.
