To calculate percent off, multiply the original price by the discount percentage (as a decimal) to get the discount amount, then subtract that from the original price. For example, 20% off $279 means: 0.20 × $279 = $55.80 discount, so the final price is $279 − $55.80 = $223.20.
A stackable discount is a second percentage discount applied to the price after the first discount has already been applied — not to the original price. For example, if an item is 20% off and you have a 15% coupon, the coupon applies to the already-discounted price, not the original. This means the total savings are less than simply adding the two percentages together.
20% off $100 is $20 in savings, bringing the final price to $80. You calculate this by multiplying $100 × 0.20 = $20 and subtracting from the original: $100 − $20 = $80.
10% off any price means you pay 90% of the original. Simply multiply the original price by 0.10 to find the discount, then subtract it. For example, 10% off $50 = $5 off, so you pay $45.
15% off means you save 15 cents for every dollar of the original price. Multiply the price by 0.15 to get the savings, then subtract. For instance, 15% off $200 = $30 savings, leaving a final price of $170.
30% off means you pay only 70% of the original price. Multiply the original price by 0.30 to find your savings. For example, 30% off $150 = $45 off, so the final price is $105.
A percent off discount scales with the price — the higher the original price, the larger the dollar savings. A fixed dollar discount (e.g. $10 off) is a flat reduction regardless of the original price. Percent off discounts are more common in retail promotions and sales events.
Black Friday discounts vary widely by category. Electronics and appliances may see 20–40% off, while clothing and accessories can be discounted 30–70%. Doorbusters sometimes exceed 50% off, though those deals are limited in quantity. Using a percent off calculator helps you verify whether a deal is as good as advertised.
