discount calculator applies a percentage off an original price to give you the final sale price and the amount you save. The saving is the price multiplied by the discount percent and divided by 100; the sale price is what remains after subtracting it. Add a second discount or a tax rate under advanced options to see the true checkout price. If you add a second 10% coupon, it comes off the already-reduced 60 — not the original — giving 60 × 0.90 = 54. That's why stacked discounts
