comment Why is “a 100% increase” the same amount as “a two-fold increase”?
@jim: yes, and in that case you'd be thinking in terms of multiples. But you could also want to refer to the difference between final and initial amount, and then you would use percentage. That could happen, for instance, if the final amount is not a whole number multiple (like 2, 3, ...) of the initial amount.
