Discount Calculator
Sale price and savings for percentage or fixed discounts.
How it works
Enter your numbers and the results update instantly. Fields marked * are required; the rest can stay at zero. Nothing you type is saved or sent anywhere.
Formula
Sale price = original_price - discount_amount
Discount amount = discount_type=='percentage' ? original_price*discount_value/100 : discount_value
Customer saves = discount_amount / original_price * 100
Tips: what your result means
- Re-run the numbers whenever your price, courier rate, fees or offer changes.
- If your margin is under 10%, small changes in ad cost or returns can wipe out profit.
