Frequently Asked Questions
What three questions does this answer?
What is X% of Y; X is what percent of Y; and the percentage increase or decrease going from X to Y — the three forms almost every percentage question takes.
Is the increase calculation signed?
Yes, a decrease is reported as a negative change so you can tell the direction at a glance instead of reading an absolute difference.
