Every 100 kcal of miso brings 6.5 g of protein. On that measure it ranks 25th of the 31 soy foods in this database and 381st of all 796 foods on the site. Measured by weight instead, its 12.8 g per 100 g ranks 16th in its group.
Around 26% of the calories in miso come from protein, so it is moderately protein-dense. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
Weight for weight, miso has 2.1 g of protein for each gram of fat (12.8 g against 6.01 g per 100 g).
Set against meatless bacon, another soy food entry in the database, a serving carries about 1 g more protein (meatless bacon has 1.2 g per 2 strips).
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 measured by volume at 17 g, and it covers about 4% of the 50 g FDA Daily Value for protein.

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.

Sample figures for one made-up week against a 110 g goal, not your data. Red bars met the goal. Your own log fills this in with Premium.
12.8 g. The 1 tbsp serving used on this page weighs 17 g and so carries 2.2 g.
How much protein do you get per 100 calories of miso?
6.5 g. That figure divides its 12.8 g of protein per 100 g by its 198 kcal per 100 g, so it does not depend on serving size.
Is the protein in miso complete?
Yes. The protein in miso 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 miso?
About 4%. One 1 tbsp serving has 2.2 g, and the FDA Daily Value for protein is 50 g.
