How to calculate a discount
Multiply the price by the discount percentage to get the savings, then subtract: a $100 item at 25% off saves $25 and costs $75. The shortcut is to multiply by what you still pay: price × (1 − discount), so 100 × 0.75 = 75.
Stacked discounts do not add up
"25% off plus an extra 10%" is not 35% off. The second discount applies to the already-reduced price. $100 at −25% is $75; another −10% is $67.50 — an effective 32.5% off, not 35%. Coupons that stack always come out a little less than the sum.
Discount before or after tax
Discounts are applied to the pre-tax price, and sales tax is then charged on the reduced amount — so a discount also trims the tax a little. To see the final out-the-door price, run the sale price through the sales tax calculator.
