Calculate the final sale price and total savings after applying one or two successive discounts.
A discount calculator figures out the final sale price and total savings after applying one or two successive percentage discounts to an original price. This is especially useful for "stacked" discounts — such as a storewide sale percentage combined with an additional coupon — where the second discount applies to the already-reduced price, not the original price, resulting in a total discount that's less than simply adding the two percentages together.
Each discount is applied to the price as it stands after any prior discount — not to the original price. This means two discounts don't simply add together; the combined effect is always less than their sum.
Formula: Price After First Discount = Original Price × (1 − Discount 1 ÷ 100). Final Price = Price After First Discount × (1 − Discount 2 ÷ 100). Total Savings = Original Price − Final Price.
Example: For a $100 item with a 20% discount followed by an additional 10% discount, the price after the first discount is $80, and the final price after the second discount is $80 × 0.90 = $72 — a total discount of 28%, not the 30% you might expect from simply adding 20% + 10%. (Note: all figures in this example are for illustration purposes only.)
Stacked or "double" discounts are common during major sales events — a storewide percentage off, combined with an additional coupon code or loyalty discount applied at checkout. Because each discount compounds on the reduced price rather than the original, retailers can advertise large-sounding combined discounts (like "20% off plus an extra 10% off") that actually total less than the sum suggests — in this example, 28% rather than 30%. Understanding this distinction can help you evaluate whether a "deal" is as good as it sounds, and compare offers from different retailers on an apples-to-apples basis.
No. The second discount applies to the already-discounted price, not the original price. For a $100 item, 20% off brings it to $80, then an additional 10% off brings it to $72 — a total discount of 28%, not 30%.
Calculate the final price after applying both discounts in sequence, then find the total savings (original price minus final price) as a percentage of the original price. This calculator does this automatically and shows the total discount percentage.
No — mathematically, applying two percentage discounts in either order results in the same final price, since multiplication is commutative (Price × (1-d1) × (1-d2) gives the same result regardless of order).
No. This calculator shows the price after discounts only. Sales tax, if applicable, would be calculated separately based on the final discounted price (or sometimes the original price, depending on local tax rules) — check the Sales Tax Calculator for that calculation.
Yes — leave the additional discount field at 0%, and the calculator will show the result of applying just the first discount to the original price.
Advertising discounts separately (like "20% off, plus an extra 10% off with code") can make a deal sound larger than the actual combined percentage, since shoppers might mentally add the percentages together. This calculator helps you see the true total discount.
