An increase or decrease percentage of two numbers can be very useful. Let's say you are a shop that sold 8791 t-shirts in January, and then sold 4640 t-shirts in February. What is the percentage increase or decrease there? Knowing the answer allows you to compare and track numbers to look for trends or reasons for the change.

Working out a percentage increase or decrease between two numbers is pretty simple. The resulting number (the second input) is 4640 and what we need to do first is subtract the old number, 8791, from it:

Once we've done that we need to divide the result, -4151, by the original number, 8791. We do this because we need to compare the difference between the new number and the original:

-4151 / 8791 = -0.47218746445228

We now have our answer in decimal format. How do we get this into percentage format? Multiply -0.47218746445228 by 100? Ding ding ding! We have a winner:
