Discount Calculator

About Discount Calculator

Calculate how much you save and the final price after a percentage discount.

How to use this calculator

1. Enter the original price of the item.
2. Enter the discount rate as a percent or decimal.
3. Calculate the discount amount by multiplying the original price by the discount rate.
4. Subtract the discount amount from the original price to get the final price.

The formula explained

• \(\text{final price}\) = the amount paid after the discount
• \(\text{original price}\) = the item price before the discount
• \(\text{discount rate}\) = the discount written as a decimal or percent

Step by step method

1. Start with the original price shown before any discount is applied.
2. Convert the discount rate into a usable form, such as 20 percent or 0.20.
3. Multiply the original price by the discount rate to find the amount taken off.
4. Subtract that amount from the original price to get the final price.

Worked example

Suppose a jacket costs 80 dollars and is discounted by 25 percent.

1. Find the discount amount: \(80 \times 0.25 = 20\).
2. Subtract the discount from the original price: \(80 - 20 = 60\).

Tips and common mistakes

• Make sure the discount rate is entered correctly as a percent or decimal.
• Remember to subtract the discount amount, not add it.
• If there are multiple discounts, calculate them one at a time if needed.
• Check whether taxes or shipping should be included, since this calculator only finds the discounted price.
