## How To Calculate Reverse Percentage?

To calculate the reverse percentage (original value) we need to know the final number and percentage. There are two types by which you can calculate the reverse percentage. First type when you know the final number, percentage, and percentage changes (increase/decrease). We classified them as reverse percentage type 1 and reverse percentage type 2. Let's look at them one by one.

### A.Reverse Percentage Calculator 1

Before calculating the reverse percentage (original price), let's look at the percentage increase/decrease.

Final Number | ||||

Original Number | = | |||

Percentage | ||||

1 | (+/-) | |||

100 |

**+ve for percentage increase and -ve percentage decrease.**

Let's take some examples of a reverse percentage 1.

**Example a**. Price of bike reduced by 10% to $10,000. What was the original price of the bike?

Solution:

The final number: $10,000

Percentage: 10%

Percentage change: Decrease

Original Number:?

**We know the formula to calculate the reverse percentage (original value),**

Final Number | ||||

Original Number | = | |||

Percentage | ||||

1 | - | |||

100 |

*Substituting values in the formula,*10000 | ||||

Original Number | = | |||

10 | ||||

1 | - | |||

100 |

10000 | ||

Original Number | = | |

1 - 0.1 |

10000 | ||

Original Number | = | |

0.9000 |

**Original Number = 11111.1111**

**Original price of the bike = $ 11111.11**

__Use reverse percentage calculator 1 to solve such type of problem.__### B.Reverse Percentage Calculator 2

Let's get to know about the basic formula to calculate a percentage.

final Number × 100 | ||

Percentage | = | |

Original Number |

Now, we reverse it to understand the reverse percentage.

Final Number × 100 | ||

Percentage | = | |

Original Number |

Let's take some examples of a reverse percentage.

**Example a.**101 is 5% of what?

Solution:

The final number: 101

Percentage: 5%

Original Number:?

We know the formula to calculate the reverse percentage (original value),

Final Number × 100 | ||

Percentage | = | |

Original Number |

101 × 100 | ||

Percentage | = | |

5 |

10100 | ||

Percentage | = | |

5 |

**Original number = 2020**

**101 is 5 % of 2020.**

**Example b.**Two months ago Mike brought an iPhone. He forgot the exact amount of an iPhone but he knows he got 5% off and saved $50 on that deal. Now Mike wants to know the original amount of that iPhone.

Solution:

The final number: $50

Percentage: 5%

Original Number:?

We know the formula to calculate the reverse percentage (original value),

Final Number × 100 | ||

Percentage | = | |

Original Number |

50 × 100 | ||

Percentage | = | |

5 |

5000 | ||

Percentage | = | |

5 |

**Original number = 1000**

50 is 5 % of 1000.
