Formula
Sale price = original × (1 − discount%). Amount saved = original − sale price. Stacked discounts multiply, not add: a 20% + 10% stack is 1 − (0.8 × 0.9) = 28%, not 30%.
Worked Example
A $120 item with a 25% discount.
- Original price
- $120
- Discount
- 25%
- Result
- $90 (save $30)
$120 × (1 − 0.25) = $90.
When to Use This Calculator
- Decide between two offers quickly without spreadsheet math.
- Stack coupons, discounts, and tax correctly.
- Spot fake "sales", a higher price with a discount isn't always the deal.
Limitations & Common Mistakes
- Results are estimates, real-world outcomes depend on factors not captured in a simplified calculation.
- Always verify critical numbers against an authoritative source or domain expert before acting on them.
