Discount calculator
Enter the original price and the discount percent — see the dollar savings, the final sale price, and what share of the original price you're paying.
Formula
A discount is a reduction from the listed price, usually expressed as a percent. The math is the same whether you're looking at a 25% off coupon, a Black Friday banner, or a friends-and-family code.
Watch out for stacked discounts — they compound, they don't add. A 20% off coupon on top of a 30% off sale is not 50% off. It's 1 − (0.80 × 0.70) = 44% off. This calculator handles one discount at a time; for stacked deals, apply each one in sequence using the previous sale price as the new original.
Also beware of inflated 'list prices' — some retailers raise the MSRP just before a sale so a 40% discount lands you near the regular street price. Cross-check with price-history tools before celebrating.
Examples
- 01$199 jacket at 25% off→ Savings $49.75 · Sale price $149.25 (75% of original)
- 02$899 laptop at 15% off→ Savings $134.85 · Sale price $764.15 (85% of original)
- 03Stacked: $100 → 30% off → 20% off→ After 30%: $70. Then 20% off $70 = $14. Final $56. Effective 44% off, not 50%.
FAQ
- No. 25% off means you save 25% — you pay 75%. 25% of means you pay 25% (a 75% discount). 'Of' is way deeper. Always read carefully and double-check by computing the dollar figure.
