A single large chicken egg contains about 71 calories and 6.3 grams of protein. That number shifts depending on how you cook it, what you add, and even which type of egg you’re eating. Here’s a full breakdown so you can count with confidence.
Yolk vs. White: Where the Calories Live
Most of an egg’s calories are packed into the yolk. One large egg white has roughly 17 calories and 3.6 grams of protein. The yolk carries the remaining 54 calories along with the other half of the protein, plus nearly all the fat, cholesterol, and fat-soluble vitamins. If you’re trimming calories but still want the protein, swapping to egg whites cuts the count by about 75% per egg. The tradeoff is losing most of the nutrients that make eggs nutritionally dense in the first place, including vitamin D, choline, and B12.
Calories by Cooking Method
A plain boiled or poached egg stays close to that baseline of 71 calories because you’re not adding any fat during cooking. Frying an egg in a teaspoon of butter adds roughly 34 calories. A tablespoon of oil pushes it higher, around 40 extra calories.
Scrambled eggs climb faster because most recipes call for added dairy. Using two tablespoons of low-fat milk adds about 13 calories on top of each egg. Switch that to two tablespoons of heavy cream and you’re adding 52 calories instead. Multiply that across a two- or three-egg scramble, plus the butter in the pan, and a plate of scrambled eggs can easily land between 200 and 300 calories.
For quick reference per large egg:
- Boiled or poached: ~71 calories
- Fried in a teaspoon of butter: ~105 calories
- Scrambled with low-fat milk: ~85 calories
- Scrambled with heavy cream: ~100 calories
Calories per 100 Grams
If you’re weighing food rather than counting individual eggs, raw whole chicken egg comes in at 131 calories per 100 grams. A large egg weighs about 50 grams without its shell, which is how you arrive at roughly 65 to 72 calories per egg depending on exact size. Medium eggs run slightly smaller (around 44 grams), putting them closer to 58 calories, while jumbo eggs (56 grams or more) push toward 80.
Duck, Quail, and Other Egg Types
Not all eggs are chicken eggs, and size differences make the calorie counts vary widely. Duck eggs are significantly larger and richer, coming in at about 120 calories each. They also have more fat and a creamier yolk, which is why bakers favor them. Quail eggs sit at the opposite end: tiny, at roughly 14 calories per egg. You’d need about five quail eggs to match the calories of a single chicken egg.
Turkey and goose eggs are less common in grocery stores but follow the same pattern: bigger egg, more calories. A turkey egg is roughly 50% larger than a chicken egg, and a goose egg can be nearly three times the size.
How Eggs Compare to Other Breakfast Foods
Calories alone don’t tell you how full a food will keep you. Researchers have measured how satisfying common foods are using a satiety index, where plain white bread scores 100. Eggs score 150, meaning they keep you feeling full about 50% longer than the same calorie amount of white bread. Oatmeal scores even higher at 209. On the other end, a croissant scores just 47, making it one of the least filling breakfast options calorie for calorie.
This matters practically. Two eggs (142 calories) will likely hold off hunger longer than a croissant (about 230 calories), so the lower-calorie option may actually lead to less snacking later in the morning. Pairing eggs with a high-fiber food like oatmeal or whole grain toast gives you both a protein and a fiber source, which is about as filling as a breakfast gets.
Liquid Egg Products
Carton egg whites are pasteurized and convenient for high-protein, low-calorie cooking. A single egg white from the carton (about 2 tablespoons) provides roughly 17 calories and 3.6 grams of protein, matching what you’d get from separating a fresh egg yourself. A standard serving listed on most cartons is 3 tablespoons (equivalent to about 1.5 egg whites), landing around 25 calories.
Liquid whole-egg products are also available and typically match the calorie profile of fresh eggs, though some brands add small amounts of preservatives or coloring that can shift the count by a calorie or two. Always check the nutrition label, since formulations vary between brands.
