What is the Discount Calculator?

A discount calculator works out the final sale price of an item after applying a percentage reduction, and also shows you the exact amount saved. It is handy for shoppers comparing deals, retailers pricing promotions, and e-commerce managers planning sale events. Enter the original price and the discount percentage, and the tool instantly calculates the discounted price and total saving. You can also reverse the calculation input a sale price and original price to find out what percentage discount was applied, which is useful for auditing supplier pricing.

How to use the Discount Calculator

Choose a calculation mode using the tabs at the top: % Off calculates the discounted price from a percentage, Fixed Amount Off subtracts a specific dollar value, and Final Price → % Off works backwards to tell you what percentage discount was applied to reach a given final price. Enter your original price and the relevant discount value. The result panel shows the final price, the saving amount, and the discount badge. The bulk buying table below automatically scales up the saving for 1, 2, 3, 5, 10, and 25 units useful for wholesale pricing decisions.

Frequently asked questions

Percentage discount = ((Original Price − Final Price) ÷ Original Price) × 100. For example, if an item costs $80 originally and sells for $60: discount = ((80 − 60) ÷ 80) × 100 = 25%. Use the Final Price → % Off tab to calculate this automatically.
A discount is a temporary price reduction offered to a customer (e.g., a coupon or sale). A markdown is a permanent reduction in the retail price the item's new regular price. Mathematically they are calculated the same way, but markdowns are permanent inventory repricing while discounts are promotional.
Stacked discounts are not additive. A 20% discount followed by a 10% discount is NOT a 30% discount. After 20% off, you pay 80% of the original. Then 10% off that means you pay 90% × 80% = 72% of the original effectively a 28% total discount. Apply each discount sequentially for accurate results.
Yes. The Fixed Amount Off tab is useful for trade discounts applied as a flat fee, while the % Off tab works for standard trade discount percentages. The bulk buying table makes it easy to see total savings across multiple units, which is especially helpful for wholesale order planning.
If you know the final price and the discount percentage, the original price = Final Price ÷ (1 − discount%). For example, a $75 item after 25% off: Original = 75 ÷ (1 − 0.25) = 75 ÷ 0.75 = $100. Use the Final Price → % Off tab and enter both values to verify.
