Every 100 kcal of puffed rice brings 1.6 g of protein. On that measure it ranks 111th of the 111 grains in this database and 731st of all 796 foods on the site. Measured by weight instead, its 6.3 g per 100 g ranks 75th in its group.
Only about 6% of the calories in puffed rice come from protein, so it is more of an energy food than a protein food. It is worth eating for other reasons; the protein it adds to a day is incidental.
Weight for weight, puffed rice has 12.6 g of protein for each gram of fat (6.3 g against 0.5 g per 100 g).
Set against raisin bread, another grain entry in the database, a serving carries about 1.2 g less protein (raisin bread has 2.1 g per 1 slice).
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 14 g, and it covers about 2% 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.

How much protein do you get per 100 calories of puffed rice?
1.6 g. That figure divides its 6.3 g of protein per 100 g by its 402 kcal per 100 g, so it does not depend on serving size.
Is the protein in puffed rice complete?
No. On its own, the protein in puffed rice 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 puffed rice?
About 2%. One 1 cup serving has 0.9 g, and the FDA Daily Value for protein is 50 g.
