Frequently Asked Questions
- How do I calculate a discount?
- Multiply the original price by the discount percentage (as a decimal), then subtract from the original price. For example, 20% off $80: $80 × 0.20 = $16 discount, sale price = $64.
- How do I calculate the original price from a discounted price?
- Divide the sale price by (1 − discount rate). For a $64 item after a 20% discount: $64 ÷ 0.80 = $80 original price. Use the Reverse mode above.
- Do stacked discounts add up?
- No. Stacked discounts are applied sequentially, not added. A 20% discount followed by a 10% discount equals a 28% total discount, not 30%. Each discount is applied to the already-reduced price.
- What is the difference between discount and rebate?
- A discount reduces the price at point of sale. A rebate is a partial refund after purchase, usually requiring proof of purchase submission. Discounts are immediate; rebates are delayed.
- How do I calculate percentage savings?
- Savings % = ((Original Price − Sale Price) ÷ Original Price) × 100. For example, saving $20 on a $100 item: (20 ÷ 100) × 100 = 20% savings.
