How the Discount Calculator works

This calculator finds the sale price after a percentage discount and shows how much you save. It also handles stacked discounts and helps you compare deals — including the classic question of whether a bigger percentage off a higher price actually beats a smaller one.

Formula

Sale price = Original × (1 − Discount%); Savings = Original × Discount%

Original is the pre-discount price and discount% is the reduction as a decimal. For two stacked discounts, apply them in sequence — multiply by (1 − first) then (1 − second) — not by adding the percentages.

Worked example: a $120 item at 30% off

  1. Original = 120; discount = 30% = 0.30.
  2. Savings = 120 × 0.30 = $36.
  3. Sale price = 120 × (1 − 0.30) = 120 × 0.70 = $84.
  4. Stacking another 10% off: 84 × 0.90 = $75.60 — not the same as 40% off ($72).

How to read the result

Stacked discounts apply to the already-reduced price, so two discounts never add up to their simple sum. '30% then 10% off' is a 37% total reduction, not 40% — knowing this helps you compare offers accurately.

Common mistakes to avoid

  • Adding stacked percentages together instead of applying them in sequence.
  • Comparing percentages without checking the starting prices.
  • Forgetting that tax is usually applied after the discount.

Frequently Asked Questions — Discount Calculator

Multiply the original price by the discount as a decimal to get the savings, or by (1 − discount) to get the sale price directly.
No. A second discount applies to the already-reduced price, so 30% then 10% off equals 37% total, not 40%.
Not necessarily — it depends on the starting price. Always compare the final prices rather than the discount percentages.
