What do you need to calculate?

Display currency

The symbol changes presentation only. DiscountCalc never converts currency or infers a country.

Prices and rates

The fixed coupon cannot exceed the original price.

DiscountCalc performs price arithmetic from your inputs. It does not know coupon eligibility, official tax rules, item-level rounding, fees, or whether an offer is genuine.
