A discount calculator computes the sale price after applying a percentage discount, the discount amount, or the original price from a sale price and discount percentage. Essential for retail pricing, coupon calculations, and negotiation.
단계별 가이드
- 1Sale price = Original price × (1 − discount%)
- 2Discount amount = Original price × discount%
- 3Original price = Sale price / (1 − discount%)
- 4Successive discounts are NOT additive: 20% + 30% off ≠ 50% off
풀어진 예시
입력
$120 item, 25% off
결과
$90 sale price, $30 saved
$120 × 0.75 = $90
입력
Two successive discounts: 20% then 30%
결과
Effective discount = 44%
0.80 × 0.70 = 0.56 → 44% off, not 50%
