Discount Calculator
Sale price and savings
About This Calculator
A discount reduces the original price of an item by a percentage or fixed amount. Knowing how to calculate discounts quickly helps you compare deals, budget for purchases, and understand how much you actually save. This calculator shows both the savings amount and the final sale price.
Formula
Discount Amount = Original Price × (Rate / 100)
Sale Price = Original Price − Discount Amount
Example Calculation
A jacket originally priced at $120 is on sale for 30% off.
- Discount = $120 × 0.30 = $36.00
- Sale Price = $120 − $36 = $84.00
You save $36.00 and pay $84.00

Frequently Asked Questions
How do I calculate the sale price from a discount percentage?
Multiply the original price by (1 − discount/100). For a 30% discount: Sale Price = Original × 0.70.
How do I find the discount percentage if I know the sale price?
Divide the discount amount by the original price and multiply by 100. Discount % = (Savings ÷ Original) × 100.
What is a stackable discount?
Stackable discounts are applied one after another, not added together. A 20% off then 10% off on $100 gives $100 × 0.80 × 0.90 = $72, not $70.
