Discount Calculator
A discount calculator helps you quickly determine how much you save and what you actually pay when an item is on sale. Discounts are everywhere in retail, from seasonal sales and clearance events to promo codes and bulk purchase deals, and understanding the actual savings helps you make smarter buying decisions. This calculator takes two inputs: the original price of the item and the discount percentage being offered. It then shows the discount amount (how much money you save) and the final price you pay after the discount. Retailers often use psychological pricing and stacked discounts to make deals look better than they are, so being able to calculate the actual savings is essential. For example, a 'Buy 2 Get 1 Free' offer is effectively a 33% discount, not 50%. Similarly, a successive discount of 50% plus 50% is not 100% off, but 75% off. This calculator handles single percentage discounts, and for stacked discounts you can calculate each one in sequence. Knowing the real discount helps you compare offers across different stores and avoid impulse purchases that are not actually a good deal.
Formula
Discount Amount = Price x (Discount% / 100) Final Price = Price - Discount Amount Where: Price = Original price before discount Discount% = Discount percentage (e.g. 20 for 20%)
Example
Example 1 - Single discount: Original price = $100 Discount = 20% Discount amount = 100 x 0.20 = $20 Final price = 100 - 20 = $80 Example 2 - Stacked discounts: Original price = $100 First discount = 50% Second discount = 50% After 1st: 100 - 50 = $50 After 2nd: 50 - 25 = $25 Total savings = $75 (75% off, not 100% off) Result: A 20% discount on $100 saves you $20, final price $80. Stacked 50% + 50% = 75% off, not 100%.

Frequently Asked Questions
How do I calculate a discount?
To calculate a discount, multiply the original price by the discount percentage divided by 100. For example, a 20% discount on a $100 item is 100 x 0.20 = $20 off, so the final price is $80. To find the final price directly, multiply the original price by (1 - discount/100).
How do stacked or successive discounts work?
Successive discounts are applied one after another, not added together. For example, two successive 50% discounts on $100 give: first 50% off brings it to $50, then 50% off that brings it to $25. The total discount is 75%, not 100%. Always apply each discount to the new price, not the original.
What is the difference between discount and markup?
A discount reduces the price from the original, while a markup increases the price above the cost. A 20% discount on $100 gives $80. A 20% markup on $100 gives $120. Discounts are used in retail sales, while markups are used by businesses to set selling prices above their cost.
Is a bigger discount percentage always a better deal?
Not necessarily. A 50% discount on an overpriced item may still cost more than the same item at full price at another store. Always compare the final price, not just the discount percentage. Also watch for fake discounts where the original price is inflated to make the discount look bigger.
How do I calculate the original price from a discounted price?
If you know the final price and the discount percentage, the original price is Final Price / (1 - Discount/100). For example, if you paid $80 after a 20% discount, the original price was 80 / (1 - 0.20) = 80 / 0.80 = $100.
What is a good discount percentage?
It depends on the product category. For clothing and seasonal items, 40-70% off is common during sales. For electronics, 10-30% is typical. For groceries, discounts are usually smaller (5-20%). A discount of 50% or more on a non-perishable item you were already planning to buy is generally a good deal.
