Potassium Intake Calculator

Track potassium from meals, snacks, drinks, and supplements. See deficits, surpluses, targets, and serving impact. Export reports and visualize intake patterns for smarter choices.

Calculator

Food Entries

Tip: choose a listed food to auto-fill potassium per serving, then adjust servings for your actual intake.

Formula Used

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.

How to Use This Calculator

  1. Choose a daily potassium preset or enter a custom target.
  2. Add each food item you consumed during the day.
  3. Enter potassium per serving or select a listed food.
  4. Type the number of servings for each item.
  5. Click calculate to see totals, adequacy, and contribution charts.
  6. Export the result table as CSV or PDF for records.

Example Data Table

Food Potassium per Serving (mg) Servings Daily Contribution (mg)

Spinach cooked (1 cup) 839 1.00 839
Orange juice (1 cup) 496 1.50 744

FAQs

1. What does this potassium intake calculator measure?

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.

2. Are the potassium values exact for every food brand?

No. Food values vary by brand, cooking method, ripeness, and serving size. Use package labels or trusted nutrition references when you need tighter accuracy.

3. Can I use a custom target instead of a preset?

Yes. Enter any custom daily target in milligrams. When provided, the custom target overrides the selected preset for percentage and difference calculations.

4. Why might my target differ from someone else’s?

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.

5. Is more potassium always better?

Not always. Some people must limit potassium, especially with kidney disease or certain medications. Excess intake can be risky in those situations.

6. Does the chart show total intake or food contribution?

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.

7. Can I export the results for meal tracking?

Yes. Use the CSV button for spreadsheet use and the PDF button for a printable summary. Both export the current calculation table.

8. Should I rely on this tool for medical decisions?

No. It is best for education and meal planning. For diagnosis, kidney disease, blood pressure concerns, or supplement advice, consult a qualified clinician.
