Frequently Asked Questions

What's the difference between "Basic %" and "Find the Whole"?

"Basic %" answers "what is X% of Y" (you know the whole, want the part). "Find the Whole" answers "X is P% of what number" (you know the part and the percentage, want the whole) โ€” the reverse direction.

Can the increase/decrease calculator handle negative changes?

Yes โ€” if the new value is lower than the original, it will correctly show a percentage decrease rather than an increase.
