Understanding the Basics

Before diving into the calculation, let's define some terms:

  • Original Number: The starting value, representing 100%.
  • Percentage Used/Removed: The portion that has been subtracted from the original number.
  • Remaining Percentage: The portion left after the subtraction.

Steps to Calculate the Remaining Percentage

  1. Start with 100%: Since the original number represents the whole, it's equivalent to 100%.
  2. Subtract the Used Percentage: Subtract the percentage that has been used or removed from 100%.
  3. The Result is the Remaining Percentage: The answer you get after subtraction is the remaining percentage.

Formula

The formula for finding the remaining percentage is simple:

Remaining Percentage = 100% - Used Percentage

Examples

Let's illustrate with a few examples:

Example 1: Discount

A store offers a 30% discount on an item. What percentage of the original price are you paying?

Remaining Percentage = 100% - 30% = 70%

You are paying 70% of the original price.

Example 2: Project Completion

A project is 75% complete. What percentage remains to be done?

Remaining Percentage = 100% - 75% = 25%

25% of the project remains.

Example 3: Battery Life

Your phone battery is at 92%. What percentage has been used?

Remaining Percentage = 100% - 92% = 8%

Only 8% of the battery has been used.

Why Use a Percentage Calculator?

While the formula is straightforward, manual calculations can be prone to errors. A percentage calculator, like the one available on this page, provides a quick and accurate solution. Simply input the percentage you want to find the remainder of, and the calculator will instantly display the remaining percentage.

For instance, if you are given a value (e.g., a discounted price) and want to work backwards to find the remaining percentage related to the original price or total budget, our calculator handles these inverse calculations with ease.
