Percentage of change of 12 to 0 = 100%
% change = |original value - new value|/original value * 100%
= |12 - 0|/12 * 100%
= 12/12 * 100%
= 1 * 100%
= 100%
-12%
(12/5 x 100) - 100 = 140 percent. The percentage change between 5 and 12 is a 140 percent increase.
6%
devide 9 by 12
300% increase.
You cannot. The starting value must be positive for a percentage change to make sense.

Price goes from 12 to 9 means the change is -3 -3 as a percentage of 12 is 100*(-3)/12 = -25 %
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!
18/20 as a percentage is 90%
Percentage change from V1 = 12 to V2 = 18:[ ((V2 - V1) / |V1|) * 100 ]= ((18 - 12) / |12|) * 100= (6 / 12) * 100= 0.5 * 100= 50% change= 50% increase
If the value changes from fraction1 (F1) to fraction 2 (F2), then the percentage change is 100*(F2/F1 - 1) provided F1 > 0. If F1 is 0 then the value is not defined, and if F1 <0 you get nonsense results.
