About Finance Calculators

A discount calculator is a free online tool that helps you quickly determine the final price of a product or service after a discount is applied. It saves you time compared to manual calculations and ensures accuracy every time.

Our calculator supports two types of discounts: percentage-based discounts (e.g., 20% off) and fixed-amount discounts (e.g., $50 off). You can switch between these modes with a single click.

Discount calculators are commonly used for online shopping, retail sales, coupon codes, and any situation where you need to know the exact price after a reduction.

Discounts are one of the most common pricing strategies used by retailers worldwide.

Retailers use discounts to clear inventory, reward loyalty, and attract new customers. Understanding how different discount types work helps you make smarter purchasing decisions and recognize the true value of a sale.

How to Calculate a Discount

A discount is a reduction applied to the original price of a product or service. The two most common types are percentage discounts and fixed amount discounts.

Percentage Discount:

Sale Price = Original Price × (1 − Discount % / 100)

Multiply the original price by the discount percentage (divided by 100), then subtract from the original price.

Fixed Amount Discount:

Sale Price = Original Price − Discount Amount

Subtract the fixed discount amount directly from the original price.

Example:

A $120 jacket is 25% off.

  1. Discount amount: $120 × 25 / 100 = $30
  2. Sale price: $120 − $30 = $90

Frequently Asked Questions

How do I calculate a discount?
To calculate a percentage discount, multiply the original price by the discount percentage and divide by 100. Subtract that amount from the original price. For example, a 20% discount on $100: $100 × 20/100 = $20 off, so the final price is $80.
What is the formula for discount price?
The formula is: Sale Price = Original Price − (Original Price × Discount % / 100). Alternatively: Sale Price = Original Price × (1 − Discount % / 100). For fixed discounts: Sale Price = Original Price − Discount Amount.
How do I calculate the discount percentage?
To find the discount percentage: Discount % = (Original Price − Sale Price) / Original Price × 100. For example, if a $50 item sells for $35: ($50 − $35) / $50 × 100 = 30% discount.
How do I find the original price from a discounted price?
Original Price = Sale Price / (1 − Discount % / 100). For example, if you paid $80 after a 20% discount: $80 / (1 − 0.20) = $80 / 0.80 = $100 original price.
What is the difference between percent off and fixed amount off?
A percent off discount reduces the price by a percentage of the original value (e.g., 20% off $100 saves $20). A fixed amount off subtracts a specific dollar amount regardless of the price (e.g., $20 off any item saves $20). Percentage discounts scale with price, while fixed discounts are constant.
