Percentage Calculator Help

Welcome to the help page for our Percentage Calculator! This guide will walk you through how to use each section of the calculator to quickly and accurately perform various percentage calculations.

How to Use the Calculator

Our calculator is divided into three main sections, each designed for a specific type of percentage problem. Simply enter your numbers into the fields, and the result will update automatically.

1. What is X% of Y? (Percentage of a Number)

This section helps you find a specific percentage of a given number.

  • When to use it:

    • Calculating a discount amount (e.g., 20% off a $100 item).

    • Finding the tax amount on a purchase.

    • Determining a tip amount.

  • How to use it:

    1. Percentage (%): Enter the percentage you want to find. For example, if you want to find 20%, enter 20.

    2. Number: Enter the total number or base value. For example, if you want 20% of 150, enter 150.

    3. Result: The calculator will instantly display what that percentage of the number is.

    Example: If you enter 20 in “Percentage (%)” and 150 in “Number”, the result will be 30.00 (because 20% of 150 is 30).

2. X is what percent of Y? (Percentage Value)

Use this section to determine what percentage one number is of another.

  • When to use it:

    • Calculating your grade on a test (e.g., 25 correct answers out of 30 questions).

    • Finding the percentage of completed tasks.

    • Understanding what portion of a budget has been spent.

  • How to use it:

    1. Number (X): Enter the part of the total you are interested in. For example, if you want to know what percentage 25 is of 200, enter 25.

    2. Total (Y): Enter the total or whole number. For example, if the total is 200, enter 200.

    3. Result: The calculator will show you what percentage X is of Y.

    Example: If you enter 25 in “Number (X)” and 200 in “Total (Y)”, the result will be 12.50% (because 25 is 12.5% of 200).

3. Percentage change from… (Percentage Increase/Decrease)

This section calculates the percentage increase or decrease between two values.

  • When to use it:

    • Analyzing sales growth or decline.

    • Tracking changes in population or prices.

    • Calculating profit or loss percentages.

  • How to use it:

    1. Original Value: Enter the starting number. For example, if a price went from 50 to 75, enter 50.

    2. New Value: Enter the ending number. For example, if the price went from 50 to 75, enter 75.

    3. Result: The calculator will display the percentage change. A positive number indicates an increase, and a negative number indicates a decrease.

    Example: If you enter 50 in “Original Value” and 75 in “New Value”, the result will be 50.00% (indicating a 50% increase). If you entered 75 as the Original Value and 50 as the New Value, the result would be -33.33% (indicating a 33.33% decrease).
