Calories in egg yolk (raw)
Calories, protein, carbohydrate and fat per 100 g and per serving, from the USDA reference database — plus what actually changes the number on your plate.
Short answer
100 g of egg yolk (raw) contains 322 kcal, with 15.9 g of protein, 3.6 g of carbohydrate and 26.5 g of fat.
A typical serving — 1 large egg, about 17 g — is roughly 55 kcal.
That is a fairly calorie-dense food, so portion size matters.

Where the calories come from
Calories come from three macronutrients: protein and carbohydrate at 4 kcal per gram, fat at 9 kcal per gram. For egg yolk (raw) the split is:
- Protein: 15.9 g × 4 = 63 kcal — 20% of calories
- Carbohydrates: 3.6 g × 4 = 14 kcal — 5% of calories
- Fat: 26.5 g × 9 = 239 kcal — 75% of calories
- Most of the energy in egg yolk (raw) comes from fat (75% of calories).
- With 15.9 g of protein per 100 g it counts as a high-protein food.
- That is 4.9 g of protein per 100 kcal — a useful number when protein is your target.
- For 200 kcal you can eat about 60 g.
Compare preparations
The same food, prepared differently. Cooking removes water (so calories per 100 g rise), adds fat (so they rise further), or both.
| Preparation | Calories | Protein | Carbohydrates | Fat |
|---|---|---|---|---|
| Egg (hard-boiled) | 155 | 12.6 g | 1.1 g | 10.6 g |
| Egg (fried) | 196 | 13.6 g | 0.8 g | 14.8 g |
| Egg (scrambled) | 149 | 10 g | 1.6 g | 11 g |
| Egg (raw) | 143 | 12.6 g | 0.7 g | 9.5 g |
| Egg white (raw) | 52 | 10.9 g | 0.7 g | 0.2 g |
| Egg yolk (raw)this page | 322 | 15.9 g | 3.6 g | 26.5 g |
| Omelette (plain omelette) | 154 | 10.6 g | 0.6 g | 11.7 g |
What actually changes the number
One large yolk is 55 kcal — about three quarters of the egg's total energy in a third of its weight. It carries nearly all the fat and most of the vitamins A, D and B12.
How accurate are these numbers?
The values on this page are reference averages from the USDA FoodData Central database (SR Legacy release), measured on samples of egg yolk as sold and prepared in the United States. Your portion will differ: produce varies by variety and ripeness, meat by cut and trim, and anything cooked by the fat and water it gained or lost.
For most foods the per-100 g figure is reliable to within about 10%. The larger uncertainty is almost always the weight of what is on your plate and the cooking fat you cannot see — the two things worth checking before you worry about the database.

Can I track egg yolk by taking a photo?
