How to use the discount calculator

Enter the original price of the item, choose whether your discount is a percentage or dollar amount, and add the discount value. If a store gives you a second discount, such as an extra 10% off clearance, add it as the optional second discount. The calculator applies discounts in order, which is how many online stores handle stacked markdowns. For example, 20% off followed by 10% off is not the same as 30% off.

Example

If a jacket costs $100 and the store offers 25% off, the discount is $25 and the final price is $75. If you add an extra 10% off after that, the second discount applies to $75, not the original $100.

When this tool is useful

Use this tool before shopping categories like Fashion & Apparel, Electronics & Gadgets, Home & Garden, and Beauty & Personal Care where percentage discounts are common. If you also need to add shipping or tax, use the final price calculator next.

Discount Calculator FAQ

Direct answers to common shopper questions.

How do I calculate 20% off?

Multiply the original price by 0.20 to find the discount amount, then subtract it from the original price. For example, 20% off $50 saves $10, so the final price is $40.

Is 20% off plus 10% off the same as 30% off?

Usually no. If discounts are applied one after another, 20% off followed by 10% off gives an effective discount of 28%, not 30%.

Does this calculator include tax and shipping?

This discount calculator focuses on the item discount. Use the final price calculator if you want to include tax, shipping, or extra fees.
