Discount Calculator
Enter the original price and discount percentage to see exactly how much you save and what the final price will be. Useful for sales, promotions, and comparing deals.
Formula
Discount Amount = Original Price × (Discount % ÷ 100) Final Price = Original Price − Discount Amount
Multiply the original price by the discount rate to find the savings amount. Subtract that from the original price to get the final price you pay.
Worked Examples
Frequently Asked Questions
How do I calculate a percentage discount?▾
Multiply the original price by the discount percentage divided by 100. For 30% off $80: $80 × 0.30 = $24 discount. Final price = $80 − $24 = $56.
Do multiple discounts stack?▾
Successive discounts are applied one after another, not added together. A 20% discount followed by a 10% discount on $100 gives $72 — not $70. Each discount applies to the reduced price.
How do I find the original price from a discounted price?▾
Divide the final price by (1 − discount rate). If you paid $75 after a 25% discount: $75 ÷ 0.75 = $100 original price.
What is 20 percent off a price?▾
To find 20% off, multiply the original price by 0.20 to get the discount amount, then subtract. For example, 20% off $80 = $80 × 0.20 = $16 discount. Final price = $80 − $16 = $64.
