Calculadora de Economia com Cupons — Formula

How Coupon Savings Are Calculated

Coupons come in two forms: a percentage off the total, or a fixed dollar amount. This calculator handles both and shows the effective discount rate.

Percentage Coupon

Savings = Cart Total x Coupon % / 100

Fixed Dollar Coupon

Savings = Coupon Dollar Amount

Exemplo Resolvido

You have an $85 cart and a 15% off coupon.

  1. Coupon type: Percentage off
  2. Savings = $85.00 x 15 / 100 = $12.75
  3. Final total = $85.00 - $12.75 = $72.25
  4. Effective discount = 15.0%
