Enter the Discount Percentage you want to apply (0–100%).

Formula

Discount Amount = Original Price × (Discount% / 100)
Final Price = Original Price − Discount Amount

The discount amount is the portion of the original price that is removed. The final price is what you actually pay after the discount is applied.

Understanding Discount Types

Percentage Discount: The most common type. A 20% discount on a $100 item saves you $20, and you pay $80.

Fixed Amount Discount: A flat dollar amount off, such as $15 off any purchase. This is equivalent to a percentage that varies by item price.

Buy One Get One (BOGO): Often advertised as “50% off” when buying two items. The effective discount per item depends on the promotion terms.

Reverse Discount (Finding Original Price): If you know the final price and discount rate, calculate the original price as: Original = Final / (1 − Rate/100). For example, $80 after 20% off means Original = $80 / 0.80 = $100.

Examples

Flash Sale: Laptop originally $1,200, 15% off. Discount = $180. Final price = $1,020. You save $180.

Coupon Code: Shoes originally $85, 30% off coupon. Discount = $25.50. Final price = $59.50. You save $25.50.

Clearance Rack: Jacket originally $200, 50% off. Discount = $100. Final price = $100. You save $100.

Frequently Asked Questions

How do I calculate a percentage discount?

Multiply the original price by the discount percentage divided by 100. For example, a 25% discount on a $200 item: $200 × 0.25 = $50 discount. Final price = $200 − $50 = $150.

How do I find the original price from a discounted price?

Divide the discounted price by (1 minus the discount rate as a decimal). For example, if you paid $75 after a 25% discount: Original = $75 / (1 − 0.25) = $75 / 0.75 = $100.

What is a stackable discount?

A stackable discount means multiple discounts can be applied one after another. For example, 20% off followed by an extra 10% off. Note: this is not the same as a flat 30% off. Each discount applies to the already-reduced price, so the effective total is 28% off.
