Percentage Change Calculator
This calculator can calculate how many percent one number changed compared to another number.
Please enter a number in the Number 1 box and what that number changed to in the Number 2 box:
The formula to calculate percentage change is as follows:
((N2-N1)/N1)*100 = PC
N1 = Number 1 (Original)
N2 = Number 2 (Changed to)
PC = Percentage Change
Note that if the change is more, then the percentage change will be positive, and if the change is less, then the percentage change will be a negative percentage change.
Here is the math to show you how we calculated the percentage change:
