Select Try the example in the form to load these values and calculate them again. This replaces the current form inputs. Compare the result with the method and worked explanation below.
The method, explained
Savings = original price × discount ÷ 100. Sale price = original price − savings.
A 25% discount on 120 saves 30 and leaves a sale price of 90.
What to keep in mind
The result excludes tax and shipping. Multiple discounts should be applied one after another; two 20% discounts do not equal 40%.
Common questions
Can I use any currency?
Yes. Both price and savings use whichever currency you entered. No currency conversion occurs.
How do I handle two discounts?
Apply the first discount, then use its sale price as the original price for the second discount.
