How do I calculate a discount?

Multiply the price by the discount percentage divided by 100. Subtract that from the original price.

Can I stack two discounts?

Apply them one after another, not by adding them. 20% off then 10% off is 28% off, not 30%.

Divide the amount saved by the original price and multiply by 100.

Enter the original price and the discount percentage to see the sale price and your saving.

Original Price

Discount: 20% off

Calculate the final sale price and total savings from a discount percentage — for shopping, budgeting, and retail.

Sale price = original × (1 - discount%). Savings = original × discount%.
