Every 100 kcal of egg brings 8.4 g of protein. On that measure it ranks 5th of the 20 eggs in this database and 287th of all 796 foods on the site. Measured by weight instead, its 12.4 g per 100 g ranks 13th in its group.
Protein accounts for roughly 34% of the calories in egg, making it moderately protein-dense. The rest comes from fat and carbohydrate, so it adds a solid amount of protein while still carrying real energy - useful when you are eating to a calorie target rather than under one.
Weight for weight, egg has 1.2 g of protein for each gram of fat (12.4 g against 9.96 g per 100 g).
Set against fried egg, another egg entry in the database, a serving carries about 0.1 g less protein (fried egg has 6.3 g per 1 large).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving quoted here is counted by piece at 50 g, and it covers about 12% of the 50 g FDA Daily Value for protein.
Rich in leucine, the amino acid that most strongly triggers muscle-protein synthesis. Eggs are a benchmark reference for protein quality.

Per-100 g values are the amino acid analysis on the USDA record. The serving and per-gram-of-protein columns are arithmetic on those values; they are not a protein quality score.

Poached egg - 8.7 g per 100 kcal, 6.3 g per 1 large
12.4 g. The 1 large serving used on this page weighs 50 g and so carries 6.2 g.
How much protein do you get per 100 calories of egg?
8.4 g. That figure divides its 12.4 g of protein per 100 g by its 148 kcal per 100 g, so it does not depend on serving size.
Is the protein in egg complete?
Yes. The protein in egg supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own.
What share of the protein Daily Value is one serving of egg?
About 12%. One 1 large serving has 6.2 g, and the FDA Daily Value for protein is 50 g.
