What is the correct answer for percent change when the start amount is zero dollars $0?
I'd personally display "n/a" The only other answer that makes sense to me other is "infinity" (phone keyboard doesn't allow me to input the symbol). This would at least allow you to show direction by using positive and negative  infinity and mathematical as the the initial value approaches zero the percentage change approaches infinity which is the closet you can get to a meaningful value
