How much fat is there? It says 13 grams, but this can any where 12.51 to 13.49 grams, since they are rounded to 13.

If you plug that information into the calculator, and get negative results, this is because of this type of rounding on the manufacturers part. So getting -1, or +1 is possible, the calculator is intended to catch false lables, when the difference in carbs can 4-10 grams!
