How to Calculate Discounts and Savings
A discount calculator is an essential everyday tool for shoppers, retailers, and anyone who wants to quickly determine how much they will save or pay after a percentage discount. The basic formula is simple: Savings = Original Price x (Discount Percentage / 100), and Final Price = Original Price - Savings. This calculator automates both directions of the calculation.
In the standard mode, enter the original price and discount percentage to find the savings amount and final price. In reverse mode, enter the final price you paid and the discount percentage to discover what the original price was before the discount. This is useful when a store only shows the sale price and you want to know the true value of the deal.
The double discount feature handles stacked promotions, where two percentage discounts are applied in succession. A common misconception is that a 20% discount plus a 10% discount equals 30% off. In reality, the second discount applies to the already-reduced price: 20% off 100 gives 80, then 10% off 80 gives 72, which is only a 28% effective discount. This calculator shows both the individual and combined effective discount so you can evaluate promotional offers accurately. No currency symbol is used, making it compatible with any currency.
Frequently Asked Questions
How do you calculate a discount?
To calculate a discount: Savings = Original Price x (Discount % / 100). Final Price = Original Price - Savings. For example, a 20% discount on an item priced at 80 gives savings of 16, so the final price is 64.
How do stacking (double) discounts work?
Stacking discounts means applying two discounts sequentially, not by adding them. A 20% discount followed by a 10% discount does not equal 30%. The first discount reduces the price, then the second discount is applied to the already-reduced price. For example, 100 with 20% off becomes 80, then 10% off 80 gives 72 — equivalent to a 28% total discount.
What is the difference between a discount and a sale price?
A discount is the percentage or amount reduced from the original price. The sale price (or final price) is the amount you actually pay after the discount is applied. If an item originally costs 50 and has a 30% discount, the discount amount is 15 and the sale price is 35.
How do I find the original price from a discounted price?
To find the original price: Original Price = Final Price / (1 - Discount % / 100). For example, if you paid 70 after a 30% discount, the original price was 70 / 0.70 = 100. Use the "Find Original Price" mode in this calculator for instant results.
