How it works
This answers “A is what percent more (or less) than B?” — not the same as “A is what percent of B.” The base is always B, so 120 is 20% more than 100 (not 120% of 100).
Frequently asked questions
What is the difference between “percent more than” and “percent of”?
“120 is what percent of 100?” is 120%. “120 is what percent more than 100?” is 20%. Percent more/less measures the change relative to the base, not the full ratio.
How do I calculate percentage manually?
Divide the part by the whole and multiply by 100. For “X% of Y”, multiply X by Y and divide by 100. Always check that you are using the correct base value.
What do negative percentages mean?
A negative percentage usually indicates a decrease or loss relative to the original value. For example, a −20% change means the new value is 20% lower.
