How do you calculate difference between a negative percentage and positive percentage?
You calculate the change in percentage points. Thus, the change from -5% to 7% is a change (increase) of 12 percentage points.Do not try to calculate it as a percentage change. The change from -50 to 50 is 100*100/(-50) works out as -200% while the change from 50 to -50 is 100*(-100)/50 = -200%. One goes up, the other goes down but the % change is the same!

How do you calculate percentage growth if the previous amount is a negative amount?
You do not. Percentage change (increase or decrease) makes sense only if both numbers are positive or both are negative. Consider the change from -50 to +50. You could calculate the percentage change as 100*(new-old)/old = -200% Now consider the percentage change from +50 to -50. -200% again! So, in percentage terms a change from +50 to -50 is the same as from -50 to +50.
