Reverse Percent Increase

Understanding how to reverse a percentage increase is crucial when analyzing original values before a change occurred. The Reverse Percent Increase Calculator helps you find the original amount before a known percentage increase was applied. This is especially useful in financial contexts such as calculating the original price before a markup, undoing tax or inflation effects, or estimating pre-growth values.

Let’s say you know the final price after a 20% increase, but you want to know the price before the increase. Instead of guessing, this calculator does the math instantly using a simple formula. Whether you're a student, a business owner, or someone managing expenses, this tool saves time and avoids manual errors.

Reverse Percent Increase Formula

Original Value = Final Value / (1 + Percentage Increase / 100)

Example

Suppose a product now costs $120 after a 20% increase. What was the original price?

Original Value = 120 / (1 + 20/100) = 120 / 1.2 = $100

So, the original price before the 20% increase was $100.
