About this calculator

What Is a Discount Calculator?

A discount calculator shows you what you will actually pay when something is on sale. Enter the original price and the percentage off, and it returns the sale price and how much you save. Working the other way, if you know the original and sale prices, you can find the discount percentage — which helps you tell a real bargain from a headline number.

How to Calculate a Discount

Savings = Original price × (Discount % ÷ 100) and Sale price = Original price − Savings. A shortcut is to multiply by what you keep: a 30% discount means you pay 70%, so a $45 item at 30% off costs 45 × 0.70 = $31.50, and you save $13.50.

To find the discount percentage from two prices, use Discount % = (Original − Sale) ÷ Original × 100.

Worked Example

An $80 item at 25% off saves $20, bringing the final price to $60.

Two Common Kinds of Discounts

  • Percent off — a share of the price is removed. A 10% discount on $45 saves $4.50, so you pay $40.50.
  • Fixed amount off — a set sum comes off, such as a $20 coupon on a $95 service, leaving $75.

Which one is better depends on the price. On a small purchase a fixed $10 coupon beats 10% off; on a large purchase the percentage usually wins.

Stacked Discounts Are Not Added Together

When two percentage discounts apply one after another, they multiply instead of adding. Taking 20% off and then another 15% does not equal 35% off: you pay 80% × 85% = 68% of the original, which is a 32% total discount. Apply each discount to the already-reduced price to get the right answer.

Shopping Tips

  • Compare the final price, not the size of the percentage — a larger "discount" on an inflated starting price is not a deal.
  • Remember that sales tax is usually added after the discount; check it with the Sales Tax Calculator.
  • For general percentage questions, the Percentage Calculator covers more cases.

Worked example

An $80 item with a 25% discount saves $20, bringing the final price to $60.

Frequently asked questions

How do I calculate a discount by hand?

Multiply the price by the discount rate (as a decimal), then subtract that from the original price: 80 × 0.25 = $20 off, so $80 − $20 = $60.

What if I have two discounts stacked?

Apply them one after another, not added together — a 20% then 10% discount isn't 30% off, it's 0.8 × 0.9 = 0.72, i.e. 28% off.

How do I find the original price from a sale price?

Divide the sale price by (1 − discount rate). A $60 item at 25% off started at 60 / 0.75 = $80.

Does this include tax?

No — this only applies the discount. Add sales tax separately on the discounted price if your total needs to include it.
