Use this percent discount calculator to easily calculate the final price after applying a percentage discount.
How to calculate discount?
A discount is a reduction of the basic price of a good or a service. It can occur on any stage in the process of production or sale - suppliers can put a commercial discount on material prices, or retailers can put a bright red tag that says 15% OFF! on a piece of clothing.
Discounts are often made to prompt sales of outdated stock, reward customers, attract attention or increase profits in the short term.
Oftentimes, we as customers fall into the trap of impulse buying tempted by a discount percent. However, more often than not we lose money, rather than save when we indulge in shopping by buying unnecessary goods prompted by the promise of a lower price.
Have you ever wondered how much a discount is actually worth? Maybe you have a few deals in mind, or have a percent off coupon in hand and want to know exactly what that discount percent equals in dollars. The easiest way to learn the answer is to use this discount calculator, but if you want to do the calculation by hand, use the formula:
Discounted price = Original price - Discount,
where the discount is equal to the product of the original price and the discount rate, unless it is a fixed sum discount. Therefore, the final equation for applying a percent discount is as follows:
Discounted price = Original price - Original price x Discount rate.
The discount rate is sometimes referred to as a discount ratio. This straightforward formula is behind the inner-workings of our discount calculator above.
Types of discounts
There are different types of discounts that you may come across that may invoke the need for a discount calculator.
Some are seasonal - often when seasons change big clothing stores announce 50+ % discounts. Major shoe brands like Adidas, Nike, Asics, Skechers, Fila, and Bata have established outlets for such inventory where you can get a bargain on your new shoes. The same goes for clothing companies such as Gucci, Luis Vuitton, Hermes, Prada, Chanel, Ralph Lauren, and Versace who often offer clothes on sale.
Specific social groups are given discounts based on their characteristics - these include students, military officers, the elderly, and disabled people. Individuals identified as in need of supplementing their income may be offered coupons. Usually, these people have a specific document to testify them being of a certain status. However, documents allowing discount are not exclusive to those cases - coupons also are a form of discount . Coupon or otherwise, our discount calculator can help you find out the sale price after discount.
Importantly, most companies offer special discounts to their employees, too (employee discounts).  Using these is a great option to ease the stress on your budget.
Certain dates of the calendar year like Black Friday and Cyber Monday have (rightfully or not) become synonymous with "huge discounts". Black Friday is when you can expect significant savings on purchases from brick-and-mortar stores, while Cyber Monday is when Amazon and other online retailers make generous discounts on their regular prices. Not surprisingly, our discount calculator is used most around these dates each year.
Finally, discounts may be related to a specific type of payment - many retailers prefer to be paid in cash, rather than with a bank card (credit or debit) in order to avoid transaction fees and receive the money immediately.  However, this discount practice is banned from certain contracts and contradicts the legal policy of multiple payment providers, so many merchants are forced to list the same price regardless of the payment method.
Let’s look into a few situations where you may come across a discount (and might be in need of a percentage discount calculator).
- Say you walk into a store, and see a watch worth $300 being sold with a 15% discount. You now want to know what the new price of the watch is.
Discounted price = 300 - 300 x 15% = 300 - 300 x 0.15 = 300 - 45 = $255.
Therefore, the discount is $45, and the new sales price to pay is $255.
- Cinemas often offer discounts on Halloween. This year, you see an ad for a 50% discount on the second horror movie you buy a ticket for. Movie tickets in this cinema cost $10, but you are a student and use a discount of 20%. If you decide to see two horror flicks on Halloween, your discount for the first one will be 20%, as you can only use your student’s discount.
Discounted price = 10 - 10 x 20% = 10 - 2 = $8.
However, you can buy a ticket for the second movie with a 70% discount:
Discounted price = 10 - 10 x 70% = 10 - 7 = $3.
So, seeing both films will cost you only $11 if you take advantage of the discounts. While it's not rocket science, the above math can easily be outsourced to our easy-to-use discount calculator.
Brief history of price discounts
Interestingly, discounts are a fairly recent phenomena. Percent discount calculators like this one would not be needed throughout most of human history as even the invention of money is itself only several thousand years old. Prior to that, trade deals were made in kind - a bushel of apples for a stack of hay, etc. Haggling over prices was how you got a good "discount" in the olden days. This custom is still present and even mandatory in many parts of the globe.
Without a fixed price, however, a discount doesn't really make sense. Many readers may fascinated to discover this, but fixed prices and the practice of openly displaying the price tag of a good or service is a fairly recent Western development. Price labels were introduced first by the Quakers (religious group, part of Christianity) who, among other things, believed that the fixed pricing system would promote honesty and eliminate the greed that was pervasive in their communities . It later gained wider adoption until it finally became law in most developed countries (consumer laws regarding discounts to follow).
It was partly the desire to be transparent and fair in their dealings, but it was also the industrialization of manufacturing that helped nudge this process. It wasn't until that moment that a discount on the price actually got its meaning, and so the need for a discount calculation arose.
