Discount Calculator

This discount calculator determines the final price of an item or service after implementing a discount. The discount percentage calculator can also be used reversely to determine the discount percentage and original cost of the products.

What Is The Formula To Calculate Discount?

Discount = List Price - Selling Price

Discount (%)= Discount List Price x 100

Where:

  • D = Discount Percentage
  • L = List Price
  • S = Sale Price

How To Calculate A Discount?

Percent OFF:

  • Add all the prices to get the total price 
  • Convert the discount percentage into decimal
  • Multiply the decimal value by the total price to get the saving amount
  • Now subtract the saving amount from the total price to get the discounted price 

Example:

Imagine you purchased three items priced at $35, $50, and $70, respectively. You got a 20 % price discount on this purchase. Find the price after the discount.

Solution:

Now instead of finding the 20% off 35, 20% off 25, and 20% off 70, we will calculate the total amount which is:

= $35 + $25 + $70 = $130 

Convert discount (%) into decimal value:

= 20/100 = 0.2 

Discounted Amount = 130 x 0.2 = $26

Price After Discount = 130 - 26 = $104

Fixed Amount OFF:

  • Formula: Discounted Price = Original Price - Fixed Amount
  • Example: If a $50 item is $10 off, the discounted price is $50 - $10 = $40

Percent Off on 2nd Product/3rd Product:

  • Determine the percentage off 
  • Divide the percentage by the number of products to get the discount on each product
  • Convert the price discount of the second product into decimal 
  • Now take this decimal value and multiply it by the price of the second product to get the savings

2 for 1, 3 for 2, or 4 for 3 Offers:

  • List down the products in descending order by price
  • Choose the prices of expensive products and pay for them
  • The price of the cheapest product is your saving in all cases

Double or Triple Discounts:

  • Apply discounts in a reverse sequence
  • For example, if a 30% off coupon is followed by a 10% off sale, calculate the 10% discount first, then the 30% discount to the discounted price
  • Add both discounted amounts and subtract the sum from the original price

On Multiple Units:

  • Multiply the price of each unit by the total number of units to get the original price of all the units
  • Subtract the fixed price for multiple units from the original price

To streamline the process of finding discounts and avoid human errors, it is recommended that the online discount calculator with tax be used. It will let you find the final prices of products after applying the discount and sales tax.
