How to Calculate Discounts Manually
To compute a retail discount by hand:
- Divide the percentage discount rate by 100 to get a decimal (e.g., 20% / 100 = 0.20).
- Multiply the original item price by the decimal to find your total dollar savings.
- Subtract the total dollar savings from the original price to find the final sale price.
