How many calories are in an egg?
One large egg has about 72 calories. That's 50 g of egg without the shell, with 6.3 g of protein, 4.8 g of fat and almost no carbs (0.4 g). A medium egg has about 63 calories and an extra-large one about 80. Hard-boiled, it's about 78.
Poaching keeps an egg at roughly the same number. Frying and scrambling add calories, because something goes into the pan with it.
Eggs are a cheap, easy source of protein. The yolk accounts for about 55 of those 72 calories, as the white vs. yolk table below shows.
How many calories are in a small, medium or large egg?
USDA FoodData Central lists a whole raw egg at 143 calories per 100 g and gives a standard weight for each size (USDA FoodData Central, Egg, whole, raw).
| Size | Weight | Calories | Protein | Fat |
|---|---|---|---|---|
| Small | 38 g | 54 | 4.8 g | 3.6 g |
| Medium | 44 g | 63 | 5.5 g | 4.2 g |
| Large | 50 g | 72 | 6.3 g | 4.8 g |
| Extra large | 56 g | 80 | 7.0 g | 5.3 g |
| Jumbo | 63 g | 90 | 7.9 g | 6.0 g |
Eating more than one? Two large eggs come to about 144 calories and 12.6 g of protein. Three land at about 216 calories, which is roughly a 150 g portion.
Boiled, poached, fried or scrambled: which has the most calories?
Here is one large egg cooked four ways, using USDA's entries for hard-boiled, poached, fried and scrambled eggs. The last column is the same food per 100 g, handy if you weigh your portion.
| One large egg | Weight as served | Calories | Protein | Fat | Calories per 100 g |
|---|---|---|---|---|---|
| Poached | 50 g | 72 | 6.3 g | 4.7 g | 143 |
| Hard-boiled | 50 g | 78 | 6.3 g | 5.3 g | 155 |
| Fried | 46 g | 90 | 6.3 g | 6.8 g | 196 |
| Scrambled | 61 g | 91 | 6.1 g | 6.7 g | 149 |
Protein barely changes between methods, while fat climbs once butter or oil gets involved. USDA's fried and scrambled numbers already include some fat from the pan, and the scrambled egg weighs more because other ingredients went in. Your own pan can land higher or lower, depending on how much butter or oil you use.
How many calories are in an egg white?
The white of one large egg has about 17 calories. Split the egg and the two parts look very different (egg white, egg yolk):
| Part of one large egg | Weight | Calories | Protein | Fat |
|---|---|---|---|---|
| White | 33 g | 17 | 3.6 g | 0.1 g |
| Yolk | 17 g | 55 | 2.7 g | 4.5 g |
The yolk carries about three quarters of the calories and nearly all the fat. The white is almost pure protein. That's why egg-white omelets are so light, and why most of an egg's calories come from fat. If you want to see how protein, carbs and fat turn into calories, read what macros are.
Buying liquid egg whites by weight? USDA puts raw egg white at 52 calories and 10.9 g of protein per 100 g.
How much protein and cholesterol is in an egg?
A large egg gives you about 6.3 g of protein. Per 100 g that's 12.6 g, less than half of what cooked chicken breast has, though eggs are much easier to fit into breakfast. A cup of nonfat Greek yogurt is another easy morning option with more protein.
USDA lists 372 mg of cholesterol per 100 g of whole raw egg, which works out to about 186 mg in one large egg (whole egg). Almost all of it sits in the yolk. The white has none (egg white).
Does cooking oil change the count?
Cooking adds calories fast. USDA lists a tablespoon of olive oil at about 119 calories and a tablespoon of butter at about 102. An egg won't soak up all of it, but whatever it does absorb counts. See the olive oil page for how quickly a tablespoon adds up.
Track it the easy way
No need to look this up every morning. With Calorie AI, just say what you ate, for example "two fried eggs," and the app estimates the calories and macros for you. It's an estimate, not a lab result, so mention the butter or oil too if you used a lot.
