Every 100 kcal of rye crispbread brings 2.2 g of protein. On that measure it ranks 91st of the 111 grains in this database and 684th of all 796 foods on the site. Measured by weight instead, its 7.9 g per 100 g ranks 67th in its group.
Only about 9% of the calories in rye crispbread 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, rye crispbread has 6.1 g of protein for each gram of fat (7.9 g against 1.3 g per 100 g).
Set against corn tortilla, another grain entry in the database, a serving carries about 0.6 g less protein (corn tortilla has 1.4 g per 1 tortilla).
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 counted by piece at 10 g, and it covers about 2% 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.
7.9 g. The 1 crispbread serving used on this page weighs 10 g and so carries 0.8 g.
How much protein do you get per 100 calories of rye crispbread?
2.2 g. That figure divides its 7.9 g of protein per 100 g by its 366 kcal per 100 g, so it does not depend on serving size.
Is the protein in rye crispbread complete?
No. On its own, the protein in rye crispbread 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 rye crispbread?
About 2%. One 1 crispbread serving has 0.8 g, and the FDA Daily Value for protein is 50 g.
