Eggs are naturally low in sodium — a large chicken egg contains only about 63 mg, and nearly all of that is in the white. The real sodium surprise comes from what you add: a pinch of table salt or a splash of soy sauce can add hundreds of milligrams in an instant. This calculator estimates the total sodium in your egg dish based on egg size, how many eggs you eat, which part of the egg you consume, and any salt or seasoning you add.
Whether you're managing blood pressure, following a low-sodium diet for kidney health, or just keeping an eye on your daily sodium target, this tool gives you a fast, clear answer. It also breaks down the total into sodium from the eggs themselves and sodium from added seasonings, so you can see exactly where the numbers come from.
🥚 Egg Sodium Calculator
How to Use This Calculator
- Select the size of the eggs you're using — small, medium, large, extra large, or jumbo — from the dropdown.
- Enter how many eggs are in your serving or recipe. The default is one.
- Choose whether you eat the whole egg, just the white, or just the yolk. Most of an egg's sodium is in the white.
- Pick a seasoning from the dropdown and type in the amount, choosing teaspoons, tablespoons, or grams as the unit.
- Press Calculate Sodium to see the full breakdown, and use Reset to clear the form.
Preset buttons apply common amounts instantly — ¼ teaspoon of table salt, ½ teaspoon of table salt, or a tablespoon of soy sauce — so you can compare your usual eating habits without typing anything.
How the Sodium Is Calculated
The baseline values come from USDA FoodData Central, which lists a large raw whole egg (about 50 g) at roughly 63 mg of sodium. Nearly all of that sodium is in the white, so the calculator applies a fraction based on the part you eat: 100% for a whole egg, about 85% for whites only, and about 15% for yolks only. Smaller sizes scale down proportionally, so a small egg (38 g) lands around 50 mg and a jumbo egg (63 g) around 79 mg.
Seasoning values use standard averages: table salt contains about 2,325 mg of sodium per teaspoon, kosher salt about 1,920 mg per teaspoon, and soy sauce about 879 mg per tablespoon. The daily value percentage in the results uses the FDA's 2,300 mg reference amount for sodium.
Worked Example
Two-egg omelet with soy sauce: Using large eggs, the eggs themselves contribute 63 mg × 2 = 126 mg. Adding 1 tablespoon of regular soy sauce brings about 879 mg. The total lands at roughly 1,005 mg — about 44% of a 2,300 mg daily sodium budget. Switch to a reduced-sodium soy sauce (about half the sodium) and the total drops to roughly 566 mg.
Standard Sodium Values for Eggs
| Egg size | Whole egg | White only | Yolk only |
|---|---|---|---|
| Small (38 g) | 50 mg | 43 mg | 8 mg |
| Medium (44 g) | 58 mg | 49 mg | 9 mg |
| Large (50 g) | 63 mg | 54 mg | 9 mg |
| Extra large (56 g) | 70 mg | 60 mg | 11 mg |
| Jumbo (63 g) | 79 mg | 67 mg | 12 mg |
Values are rounded and may vary slightly with brand, hen diet, and exact egg weight.
Tips for Lower-Sodium Egg Meals
The American Heart Association recommends most adults keep sodium under 2,300 mg per day, with an ideal limit of 1,500 mg for people at higher risk. Eggs themselves are a low-sodium food — it's the seasoning that usually adds up.
Frequently Asked Questions
Are eggs naturally high in sodium? No. A whole large egg has only about 63 mg of sodium, roughly 3% of a 2,300 mg daily value. Added salt, soy sauce, bacon, or cheese is what typically turns an egg dish into a high-sodium meal.
Why does the egg white have more sodium than the yolk? Sodium occurs naturally in egg white as part of its mineral makeup. The white of a large egg holds most of the roughly 63 mg, while the yolk contributes only about 9 mg. That's why eating only whites still delivers most of the egg's sodium.
Do salted boiling water and egg substitutes count? Salt in boiling water does not measurably increase the sodium inside the shell. Egg substitutes and liquid egg products, however, are often salted during processing — check the nutrition label, as a single serving can contain 100–150 mg or more.
