How does the Discount Calculator work?
Calculating a discount is a straightforward process. The basic formula to find the discount amount is to multiply the original price by the discount percentage represented as a decimal. Then, subtract that amount from the original price to get the final sale price.
Formula: Original Price - (Original Price * Discount / 100)
For example, if a shirt costs $50 and is 20% off: $50 * 0.20 = $10 discount. $50 - $10 = $40 final price.
Discount Formula Examples
| Original Price | Discount | You Save | Final Price |
|---|---|---|---|
| 100 | 10% | 10 | 90 |
| 500 | 20% | 100 | 400 |
| 1000 | 50% | 500 | 500 |
