Yogurt is a nutrient-dense breakfast and snack food, but if you are tracking potassium for kidney health, blood pressure goals, or general meal planning, you need to know exactly how much is in your bowl. This yogurt potassium calculator gives you a fast, science-based estimate for any portion you choose — cups, ounces, grams, or tablespoons.
Select from common yogurt types including plain whole-milk, low-fat, nonfat, and Greek varieties, or enter the exact potassium value from the nutrition label of your favorite brand with the “Other” option. The calculator converts your serving size to grams, applies the potassium density (mg per 100g), and reports total potassium in milligrams, percent of the 4,700 mg Daily Value, and a banana-equivalent comparison.
Whether you use it for diet planning, nutrition tracking apps, or simply curious about your macros, this tool turns vague “good source” labels into numbers you can use.
🥛 Yogurt Potassium Calculator
Estimate the potassium in any serving of yogurt — from whole-milk cups to Greek singles.
1. Enter the Amount
2. Choose the Yogurt Type
How to Use This Calculator
Using the calculator takes four steps:
- Enter the portion — type the number into the Amount field.
- Pick a unit — choose grams, ounces, cups, or tablespoons from the dropdown.
- Select the yogurt type — choose a preset type or “Other” to enter the exact mg per 100g from your brand’s nutrition label.
- Press Calculate — view potassium in milligrams, % Daily Value, and banana equivalents.
Potassium in Common Yogurt Types
Values vary by brand, milk source, straining method, and added ingredients. The table below shows central USDA-style estimates:
| Yogurt type | Potassium (mg/100g) | Potassium (mg per 1 cup/245g) |
|---|---|---|
| Plain whole milk | 155 | 380 |
| Plain low-fat 1% | 180 | 441 |
| Plain nonfat | 190 | 466 |
| Greek nonfat | 141 | 345 |
| Greek low-fat 2% | 141 | 345 |
| Greek whole milk | 133 | 326 |
Greek yogurts are strained, removing some whey — and along with it, some potassium. That’s why a Greek cup often contains less potassium than a regular nonfat cup even though it has more protein.
How the Calculation Works
The math is simple:
Potassium (mg) = serving weight (g) × (potassium per 100g / 100)
Weight conversions used:
- 1 cup ≈ 245 g
- 1 tablespoon ≈ 15.3 g
- 1 ounce = 28.35 g
Percent Daily Value is based on the FDA’s adult DV of 4,700 mg:
%DV = potassium (mg) ÷ 4700 × 100
Worked example
You eat ¾ cup of plain whole-milk yogurt. Convert: 0.75 × 245 ≈ 184 g. Potassium = 184 × (155/100) ≈ 285 mg. %DV = 285/4700 × 100 ≈ 6.1%. That’s about 0.68 of a medium banana (422 mg).
Another example
A 170g container of Greek nonfat yogurt: 170 × 1.41 = 240 mg, which is about 5.1% of the Daily Value.
Factors That Affect Accuracy
Brands differ. Some add milk solids, thickeners, or whey protein, which shift the potassium density. Flavored yogurts usually contain more sugar and less yogurt per gram, so their potassium per 100g can be lower than plain yogurt. If precision matters — for kidney disease meal planning or clinical diet documentation — use the exact number from the brand’s label lab analysis, not a general estimate.
Tips for Potassium Tracking
- Aim for 4,700 mg/day from food; most adults fall short.
- Yogurt is a useful but moderate source — a full cup of regular nonfat yogurt provides roughly 10% of the DV.
- To boost potassium, pair yogurt with potassium-rich fruit: a medium banana (422 mg), half an avocado (~487 mg), or apricots.
- If you are also eating leafy greens, the collard potassium calculator can help you log another common source. [Note: replace with internal link syntax if needed]
- Read the label’s serving size: a 5.3-oz Greek cup weighs ~150g, while a “single-serve” tub may be 170g.
Frequently Asked Questions
Is Greek yogurt high in potassium? Not especially. Greek yogurt is often lower in potassium per cup than regular yogurt because straining removes some whey. A 170g Greek nonfat serving has around 240 mg, while 170g regular nonfat may have around 320 mg.
What counts as a high-potassium food? The FDA defines 20% DV or more per serving as an “excellent source” and 10–19% as a “good source”. A single serving of plain nonfat yogurt is typically around 10%, while a 1-cup serving of cooked collard greens is much higher.
Can I trust the nutrition label over the calculator? Yes. The label reflects the exact product recipe. Enter that value via “Other” for the most accurate result. If your label shows potassium only in a percent (e.g., 6%), you can estimate mg as % × 4700.
Where do the type averages come from? They are standard food-composition approximations consistent with USDA FoodData Central and common brand labels. Real-world values vary. For full data, see USDA FoodData Central and the NIH Office of Dietary Supplements potassium fact sheet.
