How Discount Calculation Works

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

Discounts reduce the original price by a percentage. The final price equals the original price minus the discount amount. You can also reverse-calculate to find what discount percentage was applied given the original and final prices. Worked example: an $80 jacket discounted 25% costs $80 × 0.75 = $60, saving you $20. Stack a further 10% off at the register and you pay $54.00, because sequential discounts multiply (0.75 × 0.90 = 0.675), they never simply add to 35%.

FAQs

How do I calculate the discount percentage?

Discount % = ((Original Price - Sale Price) / Original Price) × 100. For example, $80 sale price on $100 original = 20% discount.

How do stacked discounts work?

Apply discounts sequentially. A $100 item with 20% off then 10% off: $100 × 0.80 = $80, then $80 × 0.90 = $72 (28% total discount).

What's a good discount to look for?

It depends on the product. Electronics: 15-30% is good. Clothing: 30-50% during sales. Luxury items: even 10-15% is significant.

Is 'Buy One Get One 50% Off' better than 25% off?

They're equivalent if you buy two items at the same price. BOGO 50% off two $100 items = $150 total (25% off each item effectively).

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

Original Price = Sale Price / (1 - Discount%/100). A $60 item at 25% off: $60 / 0.75 = $80 original price.
