Percentage increase/decrease from 81 to 2900?
An increase or decrease percentage of two numbers can be very useful. Let's say you are a shop that sold 81 t-shirts in January, and then sold 2900 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 2900 and what we need to do first is subtract the old number, 81, from it:
