A Percentage Calculator is a useful tool that helps you quickly find percentages, percentage increase or decrease, and original values. Whether you're working on finances, academics, business, or daily calculations, this tool simplifies percentage-based math effortlessly.

What is a Percentage Calculator?

A Percentage Calculator is an online tool that calculates percentage-related values in an instant. It allows users to perform percentage-based operations without manual calculations. Instead of solving equations, you simply input values, and the calculator does the work for you, like our mean calculator.

How Our Percentage Calculator Works

• Select the type of calculation: Choose from the available options.
• Enter the percentage (X) and value (Y): Input your required values.
• Get the result: The calculator instantly provides the answer.

What is X% of Y?

Formula: \( \text{Result} = \left( \frac{X}{100} \right) \times Y \)

Example: What is 20% of 150?

\( \left( \frac{20}{100} \right) \times 150 = 30 \)

Percentage Increase

Formula: \( \text{Increased Value} = Y + \left( \frac{X}{100} \right) \times Y \)

Example: Increase 50 by 10%

\( 50 + \left( \frac{10}{100} \right) \times 50 = 55 \)

Percentage Decrease

Formula: \( \text{Decreased Value} = Y - \left( \frac{X}{100} \right) \times Y \)

Example: Decrease 80 by 25%

\( 80 - \left( \frac{25}{100} \right) \times 80 = 60 \)

Find Original Value

Formula: \( \text{Original Value} = \frac{Y}{1 \pm \frac{X}{100}} \)

Example: After a 20% increase, the value is 120. Find the original value.

\( \frac{120}{1 + \frac{20}{100}} = 100 \)

Percentage Calculation Formula

General formula: \( \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 \)
