Discount Calculator
$
%
A discount calculator determines the sale price, savings amount, and original price in discount scenarios. Understanding discounts prevents confusion between "25% off" and "you pay 25% of the price" — very different!

Fun Fact
Research shows shoppers perceive "50% extra free" as better value than "33% off" — even though they are mathematically identical (50 extra of 100 = 150 total = 33% discount).
