Frequently Asked Questions

What does a negative percentage change mean?
A negative percentage change indicates a decrease from the initial value to the final value. For example, -15% change means the value decreased by 15%.
What is the difference between percentage change and percentage point change?
Percentage change measures the relative growth or drop of a number. Percentage point change is the simple arithmetic difference between two percentages. For instance, if interest rates rise from 4% to 5%, that is a 1 percentage point increase, but a 25% relative percentage change.
