Reading a discount correctly

A percentage discount always applies to the original price, not to any price that's already been reduced — which matters when a sale is stacked ("25% off, plus an extra 10%"). Two sequential discounts don't add together; 25% off followed by 10% off the new price works out to about 32.5% off the original, not 35%. When in doubt, calculate each step separately rather than adding the percentages.

Smarter shopping around a sale

Compare unit price, not sticker price

A "50% off" bulk pack can still cost more per unit than a smaller full-price item. Check the price per ounce, per item, or per use before assuming a discount is the better deal.

Watch for inflated "original" prices

Some retailers briefly raise a price before discounting it, so the sale looks bigger than it is. If a deal seems unusually large, a quick price-history check is worth the minute it takes.

Stack the calculator with a coupon

If you also have a coupon code, run the discount calculator first to get the sale price, then apply the coupon percentage to that new number — not the original price.

Factor in shipping and returns

A steep discount can be erased by shipping costs or a restrictive return policy. Add those into your real "final price" before deciding a deal is worth it.

A worked example

A $150 jacket with 30% off comes to $105 — a $45 saving. Stack a further 10% off that new $105 price (not the original $150), and the final price drops to $94.50 — a combined effective discount of 37%, not the 40% simple addition might suggest.

Why stacked discounts don't simply add together

Each additional discount in a "stack" applies to the already-reduced price, not the original — which is why two 20% discounts combine to a 36% total reduction, not 40%. Calculating each step separately, as this tool does, avoids the common mistake of adding discount percentages directly.

Frequently asked questions

How do I calculate a discounted price?

Multiply the original price by the discount percentage divided by 100 to find how much you save, then subtract that from the original price. For example, 25% off $80 saves $20, for a final price of $60.

How do I work out what percentage off a sale price is?

Subtract the sale price from the original price, divide by the original price, and multiply by 100. This calculator focuses on finding the final price from a known discount — for the reverse calculation, the percentage calculator's "% change" mode will get you there.

Does this include tax?

No — this calculates the discount only. Add your local sales tax to the final price separately if needed.
