This discount calculator helps you quickly determine the final price after a discount, the amount saved, or the original price before a discount was applied.
A discount calculator, whether a physical device, an app, or a set of formulas, is a powerful tool that empowers you to quickly compute various aspects of a discount. It can calculate the final price after applying a discount, the amount saved, the original price before the discount, or even the discount percentage. This tool simplifies the math involved in discount-related calculations, making it a must-have for shoppers, businesses, or anyone dealing with price reductions.
Such tools are designed to make shopping (and selling) easier, especially when multiple discounts or complicated offers are involved.
A discount is a fundamental concept in the world of shopping and business. It's a reduction in the price of an item or service, whether it's a percentage or a fixed amount deducted from the original price. This makes the item more affordable for customers and can attract buyers, encourage purchases, clear inventory, or reward loyal customers.
Discounts are usually expressed as:
For example, a store might reduce a $50 item by 20% or by $10, depending on the discount offered.
To calculate the discounted price and savings, you need to know the original price, discount percentage, or discount amount.
a. Discounted Price
The discounted price (or final price) is the amount you pay after the discount is applied. It depends on whether the discount is a percentage or a fixed amount.
Formula:
Final Price = P × (1 - d/100)
Formula:
Final Price = P - D
b. Savings
The savings is the amount you don’t pay due to the discount, equal to the discount amount.
Savings = (d/100) × P

Discounts come in a variety of forms, each with its own unique benefits and calculations. Below are common types with examples and detailed calculations to keep you intrigued and engaged:
Find concrete examples and detailed calculations on how to handle each of these discounts:
A percentage off the original price.
Example: A store offers 30% off a $40 shirt during a sale.
Discount Calculation:
A specific dollar amount off.
Example: A $50 book has a $10 off coupon.
Discount calculation:
Pay for one item, get another free (effectively 50% off two items of equal price).
Example: Two $20 mugs, buy one get one free.
Discount calculation:
Pay the full price for one and a half times the price for the second.
Example: Two $20 shirts, second at half price.
Discount Calculation:
Discounts on items at season’s end.
For example: 30% off $40 summer clothes.
Discount Calculation: Same as percentage discount above: Final Price = $28, Savings = $12.
Discount for loyal customers.
Real-Life Example: 10% off a $100 grocery bill with a loyalty card.
Discount calculation for this case:
Discount for early purchases.
Real example: Conference fee is $200 if paid early, $250 regular.
Discount Calculation:
Discount for buying in bulk.
Example: 10 items at $5 each without discount, or $4 each if you buy 10 with discount.
Discount calculation:
Money returned after purchase, similar to a discount.
For example: 5% cashback on a $100 purchase.
Calculation:
Discount via a coupon code. Especially popular for retail stores both physically and online.
For example: $5 off a $20 purchase.
Discount calculation:
Percentage Discount = (Original Price − Discounted Price)/ Original Price×100
Formula:
Discount Amount = Original Price× (Discount% / 100 )
Example:
Original price = $120, Discount = 25%
Discount amount = $120 × 0.25 = $30
Formula:
Final Price = Original Price−(Original Price×Discount %/100)
Example:
Original price = $200, Discount = 40%
Final price = $200 – ($200 × 0.40) = $200 – $80 = $120
Formula:
Original Price = Discounted Price/(1−Discount %/100)
Example:
Discounted price = $70, Discount = 30%
Original price = $70 / (1 – 0.30) = $70 / 0.70 = $100
Formula:
Percentage Discount=(Original Price−Discounted Price)/Original Price×100
Example:
Original price = $245, Discounted price = $225
Percentage discount = ($245 – $225) / $245 × 100 = $20 / $245 × 100 ≈ 8.16%
To calculate a 10% discount from a price, follow these steps:
Formulas:
Example:
If the original price is 100, then we have
Let’s see again the steps to calculate the discount amount and the final price:
Formulas:
Example:
Consider the original price is 400 for a product
Same as above, we will use the three steps to calculate the required values:
Formulas:
Example:
Let's take a service with the original price is $100.
Therefore, a service with a cost of $100 with a 30% off, then the final price will be $70, and a discount of $30.
