Frequently Asked Questions
What percentage calculations does this tool support?
Five modes are available: find X% of Y, determine what percent X is of Y, compute percentage increase or decrease between old and new values, calculate tips with bill splitting, and find the percentage difference between any two values.
How is percentage difference calculated?
Percentage difference measures how far apart two values are relative to their average. The formula is |A - B| / ((A + B) / 2) x 100. Unlike percentage change, this is symmetric: the result is the same regardless of which value you enter first.
What is the difference between percentage change and percentage difference?
Percentage change measures the relative shift from an old value to a new value and has direction (increase or decrease). Percentage difference measures the gap between two values without assigning one as the baseline, useful when neither value is the starting point.
