## Percentage increase/decrease from 11 to 9000?

An increase or decrease percentage of two numbers can be very useful. Let's say you are a shop that sold 11 t-shirts in January, and then sold 9000 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 9000 and what we need to do first is subtract the old number, 11, from it:

9000 - 11 = 8989

Once we've done that we need to divide the result, 8989, by the original number, 11. We do this because we need to compare the difference between the new number and the original:

8989 / 11 = 817.18181818182

We now have our answer in decimal format. How do we get this into percentage format? Multiply 817.18181818182 by 100? Ding ding ding! We have a winner:

817.18181818182 x 100 = 81718.18%

We're done! You just successfully calculated the percentage difference from 11 to 9000. You can now go forth and use this method to work out and calculate the increase/decrease in percentage of any numbers.
