Eggs are a nutrient-dense food, and potassium is one of the key minerals they provide. This calculator helps you quickly estimate the potassium content in eggs based on the number of eggs, their size, and whether you’re eating the whole egg, just the white, or just the yolk. Whether you’re tracking potassium for kidney health, managing blood pressure, or simply curious about your micronutrient intake, this tool gives you accurate estimates in seconds.
Simply enter the number of eggs, select the size (small, medium, large, extra large, or jumbo), and choose the part of the egg you’re consuming. The calculator will show total potassium, per-egg values, per-100g values, and the percentage of the daily value (based on 4,700 mg for adults). It also breaks down the contribution from white and yolk when you select whole egg.
This tool is ideal for dietitians, fitness enthusiasts, and anyone following a potassium-conscious diet. Use it to plan meals, compare egg sizes, or log your daily intake with confidence.

How to Use This Tool
Enter the number of eggs you plan to eat, select the egg size from the dropdown, and choose whether you're consuming the whole egg, just the white, or just the yolk. Click Calculate to see the total potassium, per-egg value, per-100g value, and the percentage of the daily value (based on 4,700 mg for adults). The preset buttons (1, 2, 3, 6) let you quickly set common serving sizes.
For whole eggs, the calculator also shows the separate contribution from the white and yolk, which can be useful if you're tracking specific parts for dietary reasons. For example, if you're on a low-potassium diet and prefer egg whites, you can see exactly how much potassium you're getting from the white alone.
You can also use the calculator to compare different egg sizes. Try switching from a large to a jumbo egg to see how much more potassium you'd get. This can help you plan meals more precisely.
How It Works
The calculator uses standard USDA nutrient data. Potassium values are based on the weight of the edible portion. For whole eggs, we use the total egg weight (including shell but adjusted for edible portion). For egg whites and yolks, we apply typical weight ratios: white ≈ 66% of the edible portion, yolk ≈ 34%.
The potassium content per 100g is approximately:
- Whole egg: 140 mg
- Egg white: 163 mg
- Egg yolk: 109 mg
These values are multiplied by the weight of the selected part to get per-egg potassium, then multiplied by the number of eggs to get the total. The daily value (DV) is based on the FDA's reference of 4,700 mg for adults, which is the recommended adequate intake for potassium. This percentage helps you understand how a serving fits into your overall daily needs.
It's important to note that these are estimates. Actual potassium content can vary by a few percent depending on the hen's diet, the season, and how the egg is cooked. However, for most practical purposes, these values are accurate enough for meal planning and dietary tracking.
Worked Examples
Example 1: 2 large eggs, whole. Each large egg weighs 50g, so potassium per egg = (50/100) × 140 = 70 mg. Total = 2 × 70 = 140 mg. That's about 3% of the daily value.
Example 2: 3 egg whites from medium eggs. Medium egg weight = 44g, white weight ≈ 44 × 0.66 = 29g. Potassium per white = (29/100) × 163 ≈ 47.3 mg. Total = 3 × 47.3 ≈ 142 mg.
Example 3: 1 jumbo egg yolk. Jumbo egg weight = 63g, yolk weight ≈ 63 × 0.34 = 21.4g. Potassium per yolk = (21.4/100) × 109 ≈ 23.3 mg. This shows that yolks are relatively low in potassium compared to whites.
These examples illustrate how the calculator works and how you can use it to estimate potassium for different scenarios. The breakdown for whole eggs is particularly useful if you're trying to understand the contribution of each part.
Tips & Best Practices
- For precise tracking, weigh your eggs after cooking, as water loss can concentrate minerals. A boiled egg may weigh slightly less than a raw one, which can affect the potassium per gram.
- Boiled eggs retain potassium well; frying may add oil but doesn't significantly change potassium content. However, if you're watching sodium, avoid adding salt.
- If you're on a potassium-restricted diet, consult your healthcare provider before making changes. This calculator is for educational purposes and should not replace professional medical advice.
- Remember that eggs are not a high-potassium food. A large egg provides about 70 mg, which is only 1.5% of the daily value. They are a good source of protein and other nutrients, but if you need to increase potassium, you'd look to bananas, potatoes, or leafy greens.
- Use the per-100g value to compare eggs with other foods. This standardized measure makes it easy to see relative potassium density.
Frequently Asked Questions
Q: Are these values accurate for all eggs? A: They are based on USDA averages. Actual values can vary slightly by feed, season, and cooking method. For most purposes, the estimates are within 5-10% of actual values.
Q: Does cooking affect potassium? A: Cooking can cause some loss of water-soluble minerals, but the change is usually minor. Boiling or poaching retains most potassium. Frying may cause a slight loss if the egg is overcooked, but the difference is not significant for dietary tracking.
Q: How does egg potassium compare to other foods? A: Eggs are moderate in potassium. A large egg provides about 70 mg, while a banana provides around 422 mg. Eggs are not a high-potassium food but contribute to overall intake. For comparison, a medium potato has about 900 mg, and a cup of spinach has about 840 mg.
Q: Should I eat egg whites or yolks for potassium? A: Egg whites contain more potassium per gram (163 mg/100g) than yolks (109 mg/100g), but because yolks are smaller, the total potassium per yolk is lower. If you're trying to increase potassium, eating whole eggs gives you a balanced mix of nutrients.
Q: Can I use this calculator for other bird eggs? A: The values are specific to chicken eggs. Duck, quail, and other eggs have different nutrient profiles. If you're eating those, you'd need to adjust the weight and potassium values accordingly.
