Every 100 kcal of chunky peanut butter brings 4.1 g of protein. On that measure it ranks 50th of the 54 legumes in this database and 516th of all 796 foods on the site. Measured by weight instead, its 24.1 g per 100 g ranks 6th in its group.
Around 16% of the calories in chunky peanut butter 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 chunky peanut butter: 49.9 g of fat per 100 g against 24.1 g of protein, a ratio of 0.5 to 1.
Set against sprouted lentils, another legume entry in the database, a serving carries about 0.8 g more protein (sprouted lentils has 6.9 g per 1 cup raw).
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 volume at 32 g, and it covers about 15% of the 50 g FDA Daily Value for protein.

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.
How much protein is in 100 g of chunky peanut butter?
24.1 g. The 2 tbsp serving used on this page weighs 32 g and so carries 7.7 g.
How much protein do you get per 100 calories of chunky peanut butter?
4.1 g. That figure divides its 24.1 g of protein per 100 g by its 589 kcal per 100 g, so it does not depend on serving size.
Is the protein in chunky peanut butter complete?
No. On its own, the protein in chunky peanut butter 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 chunky peanut butter?
About 15%. One 2 tbsp serving has 7.7 g, and the FDA Daily Value for protein is 50 g.
