Potassium is an essential mineral that supports nerve function, muscle contraction, and fluid balance. If you're tracking your daily intake for kidney health, hypertension management, or athletic performance, knowing how much potassium is in a mixed dish can be tricky. This calculator helps you estimate the total potassium content of any recipe or meal by summing the contributions of individual ingredients.
Simply enter the potassium per 100 grams (or per serving) for each ingredient along with the amount you're using, and the tool will compute the total potassium, the percentage of your daily value (based on a 4,700 mg reference), and a per-serving breakdown. It's perfect for meal preppers, dietitians, and anyone following a potassium-conscious diet.
Use the quick-add presets for common foods, or enter your own values for full flexibility. The step-by-step breakdown shows exactly how each ingredient contributes, so you can adjust portions to hit your targets.

How to Use This Tool
Start by entering the potassium content for each ingredient in your mix. You can specify it either per 100 grams or per serving, and then enter the amount you're using in grams or servings. The calculator sums up all contributions to give you the total potassium in the entire mix.
For example, if you're making a trail mix with almonds, raisins, and dark chocolate, look up the potassium values (e.g., almonds ~733 mg per 100g, raisins ~749 mg per 100g, dark chocolate ~715 mg per 100g). Enter each with its weight, and the tool will compute the total.
You can add as many ingredients as you like using the "+ Add Ingredient" button. The step-by-step breakdown shows each ingredient's contribution, making it easy to see which items are driving your potassium total.
Formula Explained
The calculation is straightforward: for each ingredient, the potassium contribution is calculated as:
Contribution (mg) = (Potassium per 100g × Amount in grams) / 100
If you're using per-serving values, the contribution is simply the per-serving potassium multiplied by the number of servings.
The total potassium is the sum of all contributions. The % Daily Value is based on the FDA's reference of 4,700 mg per day for adults. This helps you gauge how a single serving of your mix fits into your daily needs.
Worked Examples
Example 1: Simple Fruit Salad
Ingredients: 150g banana (358 mg/100g), 100g strawberries (153 mg/100g), 50g orange (181 mg/100g).
Contributions: Banana = 358 × 150/100 = 537 mg; Strawberries = 153 × 100/100 = 153 mg; Orange = 181 × 50/100 = 90.5 mg. Total = 780.5 mg. That's about 16.6% of your daily value.
Example 2: Homemade Electrolyte Drink
Mix 200ml coconut water (250 mg/100ml) with 100ml orange juice (200 mg/100ml). Total potassium = 250×2 + 200×1 = 700 mg. This is a great post-workout replenisher.
Tips & Best Practices
- Always check nutrition labels for accurate potassium values, as they can vary by brand and preparation method.
- For whole foods, use reliable databases like the USDA FoodData Central for standard values.
- If you're tracking for kidney disease, consult your healthcare provider, as potassium needs may be restricted.
- Remember that cooking methods (boiling, roasting) can alter potassium content—water-soluble potassium can leach into cooking water.
Factors Affecting Accuracy
The accuracy of your result depends on the precision of the input values. Potassium content can vary due to soil conditions, ripeness, and processing. For packaged foods, the label is your best source. For fresh produce, use average values from reputable databases.
Also, be mindful of serving sizes. If you enter per-serving values, ensure the serving size matches what you actually use. The calculator assumes a serving is equivalent to 100g when mixing units, so adjust accordingly if your serving size differs.
Frequently Asked Questions
Q: How much potassium do I need per day?
A: The FDA sets the Daily Value at 4,700 mg for adults. However, individual needs vary based on age, health status, and medications. Always consult a professional for personalized advice.
Q: Can I use this for meal planning?
A: Absolutely. This tool is ideal for meal preppers who want to balance potassium across multiple dishes. Just enter each component of your meal and see the total.
Q: What if I don't know the potassium content?
A: Use the USDA FoodData Central database or check the nutrition label. Many apps also provide this information. For common foods, you can also use our other calculators like the bulgur potassium calculator or cabbage potassium calculator for specific items.
