About this calculator
This calculator applies the basic percentage formula, result = (X / 100) × N, converting a percentage into a decimal fraction of the base number N. It's the same arithmetic whether you're finding 15% of 200 or 7.5% of 4,300 — divide the percentage by 100, then multiply.
Shoppers use it to work out a discount or sales tax at checkout, tippers use it to calculate a restaurant gratuity, and it underlies far more specialized calculations too — commission rates, interest amounts and grade weightings are all, at their core, just a percentage of a number.
