Math & Conversion
Discount Calculator
Calculate the savings and final price from a list price and discount rate, or work out the actual discount rate from two prices.
How to use
Choose whether to calculate from a discount rate or reverse-calculate from the sale price. Discount amounts are rounded to the nearest won.
Formula
Discount = list price × rate ÷ 100 · Final price = list price − discount · Actual rate = (list price − sale price) ÷ list price × 100
Example
What is the price after 20% off ₩50,000?
You save ₩10,000 and pay ₩40,000.
Frequently asked questions
- Can I find the discount rate if I know the sale price?
- Yes. Choose the reverse calculation and enter the list price and sale price.
- Can the sale price be higher than the list price?
- No. That is a price increase rather than a discount.
