Quick Answer: What Is %% Used For?

What is a 100 percent increase?

An increase of 100% in a quantity means that the final amount is 200% of the initial amount (100% of initial + 100% of increase = 200% of initial); in other words, the quantity has doubled.

An increase of 800% means the final amount is 9 times the original (100% + 800% = 900% = 9 times as large)..
