Percentage increase/decrease from 391 to 412?
An increase or decrease percentage of two numbers can be very useful. Let's say you are a shop that sold 391 t-shirts in January, and then sold 412 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.
