Curry is a global favorite, but its potassium content can swing dramatically depending on what is in the pot. A light Thai curry made mostly with coconut milk might deliver far less potassium than a lentil dal, while a potato- and spinach-heavy vegetable curry can push your intake much higher. This calculator gives you a practical estimate of the potassium in your serving so you can plan meals for balanced nutrition, athletic recovery, or a kidney-friendly eating pattern.
To get your estimate, pick the curry style closest to your meal, enter how much curry you ate (in grams, ounces, or cups), and optionally list any high-potassium add-ons like cooked spinach, potatoes, chickpeas, or lentils. The tool then calculates total potassium, potassium per 100 grams, and the percentage of the Daily Value (DV).
It is built for home cooks, meal preppers, students, and anyone tracking micronutrients. Because recipes vary, treat the result as a useful planning number rather than a laboratory measurement.

How to Use This Calculator
Start with the amount of curry in your bowl. If you are using a food scale, enter grams directly; for takeout or cooked-from-home portions, you can use ounces or cups. One cup of cooked curry weighs close to 240 g, but dense curries with chickpeas or lentils can be heavier, so weighing is always more accurate.
- Enter the curry serving amount and choose the unit (g, oz, or cups).
- Select the closest curry type from the dropdown. If you have nutrition information for a specific recipe, choose Custom and enter potassium per 100 g.
- Optionally add the weight of any high-potassium extras you put on top, such as a handful of cooked spinach, extra potatoes, or a scoop of chickpeas or dal.
- Click Calculate Potassium to see total potassium, per-100g density, and % Daily Value.
Meal-prep tip: If you made a big batch, weigh the whole cooked curry and divide by the number of servings. Then enter one serving size in the calculator, or multiply the potassium result by the fraction of the batch you actually ate.
Reference Potassium Values
The dropdown values are rounded estimates based on common home-style recipes and USDA ingredient data. Potassium is highly recipe-sensitive, so use the value closest to your actual dish.
| Curry type | Potassium (mg / 100 g) |
|---|---|
| Average mixed curry | 260 |
| Vegetable curry | 240 |
| Lentil dal | 360 |
| Chickpea chana masala | 280 |
| Chicken curry | 230 |
| Beef curry | 260 |
| Thai green curry | 220 |
| Japanese curry (roux) | 190 |
| Butter chicken | 250 |
The optional add-ons use these per-100g values: cooked spinach 466 mg, boiled potato 421 mg, cooked chickpeas 291 mg, and cooked lentils 369 mg. These are sourced from the USDA FoodData Central database.
How the Calculation Works
The calculator sums the potassium from the base curry and any added ingredients:
Total potassium (mg) = (curry K per 100g × curry weight in g / 100) + sum(ingredient K per 100g × ingredient weight in g / 100)
It then expresses the result per 100 g of the total eaten weight and as a percentage of the Daily Value:
- Potassium per 100g = total potassium ÷ total weight × 100
- % DV = total potassium ÷ 4700 mg × 100
Example: You eat 250 g of chicken curry (230 mg/100g) with 50 g of cooked spinach. Base potassium = 2.5 × 230 = 575 mg. Spinach adds 0.5 × 466 = 233 mg. Total = 808 mg, and total weight = 300 g. Per 100 g = 808 ÷ 300 × 100 = 269 mg. % DV = 808 ÷ 4700 × 100 = 17.2%.
Factors That Affect Accuracy
Restaurant curries vary even more than homemade ones. A sauce-heavy curry with extra coconut milk or cream will be less potassium-dense, while extra tomato purée, potatoes, spinach, or lentils push it higher. Salt does not change potassium content, but it does change sodium, so keep them separate in your tracking.
- Cooking method matters: if vegetables are boiled and the water is drained, some potassium is lost to the water.
- Whole spices contribute negligible potassium compared with the main ingredients.
- Portion estimation is the biggest error source; weighing your serving is much more reliable than using volume.
- Prepared curry products and restaurant dishes can vary by 20–30% from the estimates.
Important: If you have chronic kidney disease, take potassium-sparing diuretics, or have been told to limit potassium, check with your doctor or a registered dietitian. This tool is for nutrition education and meal planning, not medical advice.
Frequently Asked Questions
Is curry high in potassium?
It depends on the base. Chickpea and lentil curries are genuinely high-potassium foods, and a vegetable curry with potatoes or spinach also delivers a significant amount. Dairy- or coconut-heavy curries tend to be lower. Use the dropdown to compare.
What Daily Value should I use for potassium?
The FDA sets the Daily Value for potassium at 4700 mg for adults. This is the reference value used on Nutrition Facts labels and by this calculator. Individual needs can vary, especially for athletes or people on certain medications.
Can I use this for restaurant takeout?
As a rough estimate, yes. Choose the closest curry type and be conservative with portion size. If a restaurant provides nutrition info, choose Custom and enter their potassium-per-100g or per-serving value instead. For another fruit high in potassium, try our kiwi potassium calculator.
