Introducing the Reverse Percentage Calculator – an ingenious tool that takes the guesswork out of these tricky calculations. 

Whether you’re trying to figure out the original amount after a discount or determine the percentage increase from one value to another, this calculator will save you time and frustration. 

Say goodbye to complicated formulas and hello to simple solutions with the Reverse Percentage Calculator.

Basic Example To Use The Reverse Percentage Calculator

Certainly! Here’s a basic example of how to use the Inverse percentage calculator with some dummy values:

  • Enter 20 in the first field.
  • Enter 100 in the second field.

The problem we are solving is:

20% of ? is 100.

So 1% of ? = 100 ÷ 20 = 5

So 100% of ? = 5 x 100 = 500.

So the original number is 500.

Answer: 20% of 500 = 100.

So, in this example, you’ve used the Inverse percentage calculator to find the original.

You can follow a similar process with any percentage and total value you want to calculate.

The Formula Of The Reverse Percentage Calculator

The formula for the Inverse percentage calculator, which calculates the original value before a percentage increase or decrease, is as follows:

Original Value = Total Value / (1 + (Percentage / 100))


  • “Original Value” is the value you want to find.
  • “Total Value” is the final value after the percentage increase or decrease.
  • “Percentage” is the percentage change. If it’s a percentage decrease, make sure to use a negative value.

This formula takes the total value and divides it by (1 + (Percentage / 100)) to find the original value. 

If the percentage is positive, it represents an increase, and if it’s negative, it represents a decrease.

Final Thoughts

A reverse percentage calculator is a valuable tool for anyone who needs to quickly and accurately determine the original value when given a percentage increase or decrease.

Whether you are a student trying to solve math problems, a business owner calculating discounts or markups, or simply someone who wants to better understand percentages, this calculator can save you time and frustration.
