Every 100 kcal of boiled peanuts brings 4.2 g of protein. On that measure it ranks 48th of the 54 legumes in this database and 510th of all 796 foods on the site. Measured by weight instead, its 13.5 g per 100 g ranks 10th in its group.
Around 17% of the calories in boiled peanuts come from protein, so it is more of an energy food than a protein food. 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.
By weight, fat outweighs protein in boiled peanuts: 22 g of fat per 100 g against 13.5 g of protein, a ratio of 0.6 to 1.
Set against chickpea flour (besan), another legume entry in the database, a serving carries about 1.4 g less protein (chickpea flour (besan) has 5.2 g per 1/4 cup).
It is an incomplete protein on its own; pairing it with other plant foods across the day covers the full range of essential amino acids. The serving quoted here is measured by weight at 28 g, and it covers about 8% of the 50 g FDA Daily Value for protein.
Boiling leaves the peanuts far higher in water, so a given weight carries much less protein than roasted.

13.5 g. The 1 oz serving used on this page weighs 28 g and so carries 3.8 g.
How much protein do you get per 100 calories of boiled peanuts?
4.2 g. That figure divides its 13.5 g of protein per 100 g by its 318 kcal per 100 g, so it does not depend on serving size.
Is the protein in boiled peanuts complete?
No. On its own, the protein in boiled peanuts is short of at least one essential amino acid; other protein sources across the day fill the gap.
What share of the protein Daily Value is one serving of boiled peanuts?
About 8%. One 1 oz serving has 3.8 g, and the FDA Daily Value for protein is 50 g.
