Discount Calculator

how to calculate after-discount price?

To calculate the after-discount price of an item, you need to follow these steps:

1. Determine the original price of the item.
2. Determine the discount rate as a percentage.
3. Multiply the original price by the discount rate as a decimal (divide the discount rate by 100). This will give you the discount amount.
4. Subtract the discount amount from the original price. This will give you the after-discount price.

Here's an example:

Let's say the original price of an item is 100 and it's discounted at 20%.

1. Original price = 100
2. Discount rate = 20%
3. Discount amount = 0.20 x 100 = 20
4. After-discount price = 100 - 20 = 80
5. So the after-discount price of the item is 80.
