How do I calculate a percentage discount?

Multiply the original price by the discount percentage divided by 100. For example, a 25% discount on $120: $120 × 0.25 = $30 discount, so the sale price is $120 − $30 = $90. Alternatively, multiply by (1 − 0.25) = 0.75: $120 × 0.75 = $90.

How do I find the original price from a discounted price?

If you know the sale price and discount percentage, the original price = Sale Price ÷ (1 − Discount%/100). For example, if a $75 item is 25% off, the original price = $75 ÷ 0.75 = $100.

What does 'buy one get one 50% off' mean?

BOGO 50% off means you pay full price for the first item and half price for the second. The effective discount on the pair is 25%. For example, two $40 items: $40 + $20 = $60 total (vs. $80 full price), saving $20 or 25%.

How do stacked discounts work?

Stacked discounts are applied sequentially, not added together. A 20% discount followed by a 10% discount gives: $100 × 0.80 × 0.90 = $72, which is a 28% total discount - not 30%. The order of application does not matter for the final result.

Is a higher discount always a better deal?

Not necessarily. A 50% discount on an overpriced item may still be more expensive than a competitor's regular price. Always compare the final sale price against market prices, not just the discount percentage. The absolute savings amount is often more meaningful than the percentage.

Explanation

A discount reduces the original price by a percentage. The sale price is what you pay before tax. The final price includes any applicable sales tax. Knowing both the savings amount and the percentage helps you evaluate whether a deal is genuinely good value.

Common Mistakes to Avoid

A common mistake is forgetting to account for sales tax when budgeting. A $90 item after 25% off sounds great, but with 10% sales tax, you actually pay $99. Always calculate the final after-tax price to avoid budget surprises at checkout.
