Eggs are one of the most popular low-carb breakfasts, but the carb count is easy to over- or under-estimate — especially if you're eating only whites or yolks, or adding milk and vegetables to an omelet. This egg carbs calculator gives you a quick, reliable estimate of the total carbohydrates in your eggs based on the number of eggs, their size, the portion you eat, and any common add-ins you include.
Whether you're following a keto diet, tracking macros for bodybuilding, or just trying to understand what's on your plate, this tool simplifies the math. Enter your values, press calculate, and see the carb total broken down per egg and by source. No more guessing whether your three-egg omelet fits your daily carb budget.
Use it for meal planning, blood-sugar management, or everyday nutrition tracking, and combine it with our other food calculators for a complete macro picture.
🥚 Egg Carbs Calculator
Estimate total and net carbs in whole eggs, egg whites, or yolks — optional add-ins included.
📊 Results
Eggs have no fiber, so total carbs = net carbs.
How This Calculator Works
Eggs are naturally very low in carbohydrate. A single large egg contains roughly 0.6 g of total carbohydrate, and almost none of that is sugar or fiber. Because eggs contain no fiber, the total carb count is effectively the same as the net carb count for low-carb and keto tracking.
This calculator starts with a base carb value for the egg size you select, then applies a portion factor: 1.00 for the whole egg, 0.33 for egg whites only, and 1.00 for yolks only. That factor is multiplied by the number of eggs. Finally, any checked add-ins are added to give your total.
Carb Values by Egg Size
The table below shows the approximate carbohydrate content for one egg of each common size. These are reference values; individual eggs vary slightly with breed, diet, and weight.
| Egg size | Whole egg | Egg white only | Yolk only |
|---|---|---|---|
| Small (~38 g) | 0.4 g | 0.1 g | 0.4 g |
| Medium (~44 g) | 0.5 g | 0.2 g | 0.5 g |
| Large (~50 g) | 0.6 g | 0.2 g | 0.6 g |
| Extra large (~56 g) | 0.7 g | 0.2 g | 0.7 g |
| Jumbo (~63 g) | 0.8 g | 0.3 g | 0.8 g |
Yolk-only values use the same estimate as the whole egg because nearly all of the carbohydrate found in an egg is concentrated in the yolk; the white contributes only a trace. If you eat both the white and the yolk, count the whole-egg value.
Step-by-Step Guide
- Enter the number of eggs in the “Number of eggs” field. You can use decimals such as 1.5 if you are tracking a partial serving like one egg plus one extra white.
- Choose the egg size closest to what you actually use. Most recipes call for large eggs unless stated otherwise.
- Select the portion you plan to eat: whole egg, whites only, or yolks only.
- Check any add-ins you include. The calculator adds their carb counts to the egg base.
- Click “Calculate Carbs” to see your total, plus the carbs per egg and a breakdown of the math.
Tips for Low-Carb Egg Meals
Plain eggs are a dieter’s best friend — almost zero carbs, high-quality protein, and plenty of satiety. The carbs usually come from what you add. Keep these points in mind:
- Milk, half-and-half, and cream add lactose; a splash can add 1–2 g of carbs. Use unsweetened almond milk if you want a lower-carb alternative.
- Vegetables like onion, peppers, and tomatoes add carbs but also fiber and micronutrients. Measure them if you’re strict about your carb target.
- Sauces, ketchup, salsa, and syrup can turn a low-carb egg dish into a moderate-carb one. Check labels and log condiments.
- If you use a tortilla, English muffin, or toast, that one item usually contributes far more carbs than the eggs themselves.
Frequently Asked Questions
Are eggs keto-friendly?
Yes. Even three large whole eggs contain barely 1.8 g of total carbs. They’re a staple in most ketogenic diets because they pack protein and fat with negligible carbohydrates.
How many carbs are in an egg white vs. a yolk?
A large egg white contains roughly 0.2 g of carbohydrates. The yolk contains most of the egg’s carbs — about 0.6 g — along with nearly all the fat and many vitamins. For strict low-carb purposes, whites are even closer to zero, but whole eggs are still very low-carb.
Does cooking add carbs to eggs?
No. Frying, hard-boiling, scrambling, or poaching does not change the carbohydrate content unless you add carb-containing ingredients such as milk, flour, breadcrumbs, or a sugary sauce. Butter and oil are essentially carb-free.
Why do egg cartons sometimes list 0 g of carbs?
Nutrition labels in some countries allow “0 g” when a serving contains less than 0.5 g. Since a single large egg has about 0.6 g, it can round to 0 g or 1 g depending on the label and serving size. That’s why tracking by gram weight can be more consistent.
For a broader view of breakfast and meal carbs, you can use the bean carbs calculator for plant-based protein options or the bread nutrition calculator to see how a slice of toast fits into your meal.

Remember that eggs are one small piece of your overall diet. The best approach is to track consistently, prioritize whole foods, and use calculators like this one to make informed choices, not obsessive ones.
