FAQ
What is a discount? How do you calculate the discounted price?
A discount is a reduction in the price of a product, usually expressed as a percentage or a fixed amount. The formula for calculating the discounted price is: Original Price × (1 − Discount Percentage ÷ 100) = Discounted Price. For example, if the original price is 100 and the discount is 20%, the discounted price is 100 × 0.8 = 80. This tool calculates automatically and displays the result instantly as soon as you enter the numbers.
What’s the difference between percentage discounts and fixed-amount discounts?
A percentage discount is calculated based on a percentage of the original price. For example, an “80% price” means a 20% discount, and the discount rate stays the same regardless of the original price. A fixed-amount discount directly subtracts a fixed amount, such as “$50 off.” In this case, the discount amount is fixed, but the discount rate changes with the original price. Percentage discounts are useful for comparing deals across different prices, while fixed-amount discounts are better for knowing the exact amount saved.
When should you use the reverse calculation feature?
You can use the reverse calculation feature when you know the discounted price and the discount percentage but need to find the original price. Common scenarios include checking the original price when you see a label like “Now $80, 20% off,” verifying whether a merchant’s discount is accurate, or comparing the actual original prices of different discount offers. Simply enter the discounted price and the discount percentage, and the tool will automatically calculate the original price for you.
Can a discount percentage exceed 100%? Why?
A discount percentage cannot be equal to or greater than 100%. A 100% discount means the item is free, while a discount greater than 100% would result in a negative price, which is not reasonable in real-world commercial situations. Therefore, this tool limits the maximum discount percentage to 100%. If a higher value is entered, an error message will be shown to ensure the result remains valid.
How do you calculate the actual amount saved?
The amount saved is the original price minus the discounted price. For example, if the original price is 100 and the discounted price is 80, then you save 20. When using a percentage discount, you can also calculate it with “Original Price × Discount Percentage ÷ 100.” In fixed-amount discount mode, this tool shows both the discounted price and the discount percentage, making it easy to understand the savings and the discount rate.
What calculation modes does this calculator support?
This tool offers three modes: Percentage Discount mode, where you enter the original price and discount percentage to calculate the discounted price; Fixed Amount Discount mode, where you enter the original price and discount amount to calculate both the discounted price and discount percentage; and Reverse Calculation mode, where you enter the discounted price and discount percentage to calculate the original price. These three modes cover different calculation needs.
