How do I calculate a percentage manually?

To find a percentage, you typically divide the "part" by the "whole" and then multiply the result by 100. For example, to find what percentage 20 is of 80, you calculate (20 / 80) \times 100 = 25\%.

Can this tool help me calculate discounts while shopping?

Absolutely! To find a discount, enter the original price as Y and the discount percentage (like 20\% or 30\%) as X. The result will tell you exactly how much money you are saving.

What is the difference between percentage and percentage points?

A percentage refers to the rate of change, while percentage points refer to the arithmetic difference between two percentages. For example, a move from 10\% to 15\% is a 5 percentage point increase, but a 50\% increase.
