# Percent Off Calculator

Use this calculator to easily calculate the **final price** you need to pay after applying a percent off **discount** for products on **sale** or by using a **percent off coupon**.

## How to calculate percent off?

Percent off calculations are usually needed when there is an item or service on sale, or when you have a percent off coupon and you want to know how much that would save you in absolute terms, or how much you would need to pay in the end, after the discount has been applied. That is, if there is a 20% sale of an item that costs $100 (or €100), how much is that in USD/EUR, etc. In this case those 20 percent off means 20 bucks will remain in your pocket when you purchase.

The calculation is really straightforward:

Final price = *Original Price x ((100 - %Off) / 100)*

To calculate using our **percent off calculator**, enter the original price (base price) in the "Original price" field. Then enter the discount as percentage in the "Percent off" field, and click "Calculate".

The calculator will output the final price you need to pay and the savings you are making in absolute terms (in USD, EUR, etc.).

In many countries and jurisdictions, it is **mandatory** to display the original price, the discount percent and the final price, but that is not always the case. Furthermore, some consumer laws require retailers and other merchants that the item was sold at the original price for some minimum amount of time, for example 2-4 weeks, before a discount can be announced on it. For example, in the UK there was a 28-day price establishment recommendation, but it was recently dropped ^{[1]}. A full reference list of U.S. state regulations is available on the NIST website under the title "U.S. Retail Pricing Laws and Regulations by State".

## Practical example

Let's say there is a flat screen TV you want to buy, and it is on sale with a discount of 25% off the original price of $2,000, due to a promotion or a coupon that you have. Plugging the numbers into the above formula, we get:

*$2000 x ((100 - 25) / 100) = $2000 x (75 / 100) = $2000 x 0.75 = $1500 final price.*

The savings are then $2000 - $1500 = **$500**, so with a discount of 25% you save $500 on a $2,000 TV. Here is a brief table showing how much you would save on that same TV with different levels of discounts.

Original Price | Percent Off | Final Price | You Save |
---|---|---|---|

$2,000 | 5% | $1,900 | $100 |

$2,000 | 10% | $1,800 | $200 |

$2,000 | 20% | $1,600 | $400 |

$2,000 | 30% | $1,400 | $600 |

$2,000 | 40% | $1,200 | $800 |

$2,000 | 50% | $1,000 | $1,000 |

$2,000 | 60% | $800 | $1,200 |

$2,000 | 70% | $600 | $1,400 |

$2,000 | 80% | $400 | $1,600 |

$2,000 | 90% | $200 | $1,800 |

All numbers in the table are computed using this percent off calculator.

## Percent-Off vs Discount

Usually there is no difference, except that you can have a certain percentage off as a part of a **sale or liquidation**, and not a single product discount, but this is a minor point. For most practical purposes the two are exactly the same. In all cases, consider carefully whether you need the item, before purchasing it - you don't have to buy it just because it is some percentage off a higher price, it might still be overpriced, or it might simply not be the best fit for your needs.
