What Is a Discount Calculator?

A Discount Calculator helps you find how much money you save and what the final price is after applying a discount. This is helpful for online shoppers, in-store buyers, students, and even business owners trying to understand margins and savings.

This calculator supports three popular types of discounts:

  • Percentage discounts
  • Fixed amount discounts
  • Stacked (multi-level) discounts

You can also add sales tax if needed, which is useful for U.S. shoppers where tax is applied after discount.

Types of Discount Calculator

1. Percentage Discount

This is the most common form of discount. It subtracts a percentage from the original price.

Example:

Original Price = $1,000

Discount = 25%

You save $250 and pay $750.

Use this when:

  • A product has a flat % off (e.g., "20% Off Today Only")
  • You're shopping during sales events like Black Friday or Diwali deals

2. Fixed Amount Discount

A specific amount is deducted from the total price, regardless of the original price.

Example:

Original Price = $1,200

Discount = $200

You pay $1,000.

Use this when:

  • You have a coupon for $100 off
  • A store offers "$500 off on orders over $2,000"

3. Stacked Discounts

Sometimes you get more than one discount like 10% off + an additional 5% at checkout. This calculator applies them sequentially, just like shop keepers do.

Example:

Original Price = $2,000

1st Discount = 10% is $1,800

2nd Discount = 5% of $1,800 is $1,710

Total savings = $290

Use this when:

  • You're using promo codes or loyalty offers along with sale discounts
  • Online stores stack offers automatically or during checkout

Optional: Add Sales Tax

After discounts are applied, many stores add sales tax. This calculator lets you input your regional tax rate, ensuring your total reflects the actual amount you'll pay

Example Calculations

Example 1: Simple Percentage Discount

Let's say you are buying a shirt that costs $50 and there's a 20% discount available. The calculator shows your savings: $10 off, so you'll only pay $40.

Example 2: Stacked Discounts

A product worth $100 is on sale with a 15% discount, and you also have a coupon for an additional 10% off. The calculator first applies 15% off, bringing the price down to $85. Then it applies 10% off the $85, reducing it to $76.50.

Example 3: Fixed Discount + Sales Tax

You're purchasing a $25 item and have a $5 off coupon. After discount, the price becomes $20. If your local sales tax is 8%, the final amount comes to $21.60.

Frequently Asked Questions

How do I calculate 20% off a price?

To calculate 20% off a price, multiply the original price by 0.20 (or divide by 5). For example, 20% off $100 = $100 × 0.20 = $20 discount. The final price would be $100 - $20 = $80.

Is the discount applied before or after sales tax?

In most jurisdictions, discounts are applied before sales tax. The tax is calculated on the discounted price, not the original price. However, tax laws vary by location, so always check your local regulations.

How do "stackable" discounts work?

Stackable discounts are applied sequentially. The first discount is applied to the original price, and then the second discount is applied to the already discounted price. For example, with a 20% discount followed by a 10% discount on a $100 item: first discount = $20 (leaving $80), second discount = $8 (10% of $80), final price = $72.
