Discount Calculator
Calculate the final price and the amount you save from a percentage discount.
Final price: 80
You save: 20
About this tool
This calculator applies a percentage discount to a price, showing both the amount you save and the final price you'll actually pay — the same calculation retailers use to advertise a sale, and the one worth double-checking before you buy.
It's especially useful for comparing deals: a "30% off" sign sounds better than "$15 off", but which one actually saves you more money depends entirely on the original price, and this calculator makes that comparison instant.
The same math applies whether you're calculating a store discount, an early-payment discount on an invoice, or working out how much a coupon code is actually worth on your cart total.
Worked example
- 1Enter the original price and the discount percentage.
- 2The amount saved is the price multiplied by the discount percentage. Example: $80 at 25% off → $80 × 0.25 = $20 saved.
- 3Subtract the amount saved from the original price to get the final price: $80 − $20 = $60.
Formula
Amount saved = Price x (Discount % / 100). Final price = Price − Amount saved

Frequently asked questions
- How do I calculate a discounted price?
- Multiply the original price by the discount percentage to find the amount saved, then subtract that from the original price. Example: a $80 item at 25% off saves $20, for a final price of $60.
- How do I calculate the discount percentage from two prices?
- Subtract the sale price from the original price, divide by the original price, then multiply by 100. Example: an item dropping from $80 to $60 is a (20 / 80) × 100 = 25% discount.
- How do I calculate a discount followed by tax, or two discounts stacked?
- Apply each percentage one at a time, in order, using the result of the previous step as the new starting value — discounts and taxes are not simply additive. For example, a 20% discount followed by a 10% discount is not the same as a single 30% discount.
- What's the difference between a discount and a markdown?
- The terms are often used interchangeably in everyday language. In retail accounting, a "markdown" more specifically refers to a permanent reduction in a product's listed price, while "discount" can also refer to a temporary promotional reduction.
