For savings: Savings = Original - Sale Price. For discount rate: Rate = ((Original - Sale) / Original) × 100
Frequently Asked Questions
How do I calculate discounted price?
Multiply the original price by (100 - discount percentage) / 100. For example, $1,000 with 20% off: $1,000 × 0.80 = $800. Or find the discount amount ($1,000 × 0.20 = $200) and subtract it.
Why don't stacked discounts add up?
Each discount applies to the remaining price, not the original. 20% + 10% = 0.80 × 0.90 = 0.72, meaning 28% total discount. The second discount applies to a smaller amount, reducing its impact.
How do I find the discount percentage?
Formula: ((Original Price - Sale Price) / Original Price) × 100. For example, $500 to $375: ((500-375)/500) × 100 = 25% discount.
How do I find the original price?
Divide the sale price by (100 - discount) / 100. If it's $700 after 30% off: $700 / 0.70 = $1,000 original price.
