(New salary - old salary)/(old salary) * 100 = percent change
For example, if salary changes from 100,000 to 110,000, the percentage change is (110,000 - 100,000)/(100,000) * 100 = 10%
New Salary minus Old Salary equals Change. (N-O=C) Change divided by Old Salary times 100 equals Percent Increase. ((C/O)x100=P)
you ask someone
Half the number = total number divided by 2, and their percentage, by definition, is 50.
You cannot. The starting value must be positive for a percentage change to make sense.

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!
you ask someone
This is an increase of 16.67%
Half the number = total number divided by 2, and their percentage, by definition, is 50.
Do not calculate percentage changes when the numbers are negative since they are extremely difficult to interpret. The change from +100 to -100 is -200% The change from -100 to +100 is also -200%. The percentage changes are the same but the underlying change is completely different.
You cannot. The starting value must be positive for a percentage change to make sense.

what is the percentage of tds on salary ?
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.
Percentage change in QD = (QD2 - QD1) / QD1 For Example: QD1 = 100 QD2 = 120 then % change in QD = .2 or 20%
