Track potassium from meals, snacks, drinks, and supplements. See deficits, surpluses, targets, and serving impact. Export reports and visualize intake patterns for smarter choices.
Tip: choose a listed food to auto-fill potassium per serving, then adjust servings for your actual intake.
The calculator adds potassium across all food items using:
Total Potassium (mg) = Σ [Potassium per Serving (mg) × Number of Servings]
It then compares your total with the chosen daily target:
Percent of Target = (Total Potassium ÷ Daily Target) × 100
Difference versus target is calculated as total potassium minus target. Remaining potassium needed is the positive shortfall only.
| Food | Potassium per Serving (mg) | Servings | Daily Contribution (mg) |
|---|---|---|---|
| Banana (1 medium) | 422 | 1.00 | 422 |
| Spinach cooked (1 cup) | 839 | 1.00 | 839 |
| Orange juice (1 cup) | 496 | 1.50 | 744 |
| Yogurt plain (1 cup) | 573 | 1.00 | 573 |
It estimates total potassium consumed from selected foods and serving amounts. It also compares the result with a daily target and shows contribution patterns visually.
No. Food values vary by brand, cooking method, ripeness, and serving size. Use package labels or trusted nutrition references when you need tighter accuracy.
Yes. Enter any custom daily target in milligrams. When provided, the custom target overrides the selected preset for percentage and difference calculations.
Targets can differ due to age, sex, pregnancy, lactation, activity level, health conditions, or clinician guidance. This tool provides planning support, not personalized medical treatment.
Not always. Some people must limit potassium, especially with kidney disease or certain medications. Excess intake can be risky in those situations.
The chart shows each food item’s potassium contribution to your total intake. That makes it easier to identify the largest sources in your daily pattern.
Yes. Use the CSV button for spreadsheet use and the PDF button for a printable summary. Both export the current calculation table.
No. It is best for education and meal planning. For diagnosis, kidney disease, blood pressure concerns, or supplement advice, consult a qualified clinician.
