Discount calculator
Calculate a claimed discount, savings amount and checkout subtotal. Then verify whether the starting price is meaningful.
How to interpret the result
A mathematically correct 25% discount does not mean the item is a good deal. You need to determine whether the reference price reflects a realistic purchase alternative, whether the listing matches the intended model, and whether membership, tax or subscription costs change the outcome.
