## The Backwards Percentage Calculator Formula

Before diving into the practical applications, let’s first understand the components of the backwards percentage calculator formula:

**Original Value = Final Value / (1 + (Percentage Change / 100))**

Here, the formula has three main components:

- Original Value: The value before the percentage increase or decrease was applied.
- Final Value: The value after the percentage change.
- Percentage Change: The increase or decrease percentage.

Let’s break down the formula using an example:

Suppose you purchased an item for $120 after a 20% discount. What was the original price of the item?

**Original Value = 120 / (1 + (-20 / 100)) = 120 / 0.8 = 150**

The original price of the item was $150.

## How to Use a Backwards Percentage Calculator

There are several ways to use a backwards percentage calculator:

**Manual calculations:** You can manually calculate the original value using the formula provided above.

**Online and mobile calculator applications:** There are various online and mobile calculator applications available that can easily calculate the original value for you.

## Practical Applications of Backwards Percentage Calculators
