Percentage Calculator – Calculate Percentages Online

Introduction

Percentages are used in almost every area of daily life, including education, shopping, banking, business, salary calculations and financial planning. Whether you want to calculate exam marks, find a discount, check a salary increase or compare two values, understanding percentages is important.

A Percentage Calculator is an online tool that helps you calculate percentages quickly and accurately. Instead of solving mathematical formulas manually, you can enter the required numbers and get instant results.

Whether you need to find 20% of a number, calculate what percentage one value represents of another, or determine the percentage increase or decrease, an online Percentage Calculator makes the process simple.

What Is a Percentage Calculator?

A Percentage Calculator is a mathematical tool that calculates the relationship between a part and a whole in terms of 100.

The word percentage means "per hundred." The symbol used to represent a percentage is %.

For example:

• 10% means 10 out of 100.

• 25% means 25 out of 100.

• 50% means 50 out of 100.

• 100% represents the complete value.

A Percentage Calculator can perform several types of calculations, such as:

• Finding a percentage of a number.

• Finding what percentage one number is of another.

• Calculating percentage increases.

• Calculating percentage decreases.

• Finding the original value after a percentage change.

• Comparing two values using percentage differences.

Percentage Calculator Formulas

The calculator uses different mathematical formulas depending on the type of calculation.

1. Calculate Percentage of a Number

To find a percentage of any number, use:

Percentage Value = (Percentage ÷ 100) × Total Number

Example:

Calculate 20% of 500.

= (20 ÷ 100) × 500

= 0.20 × 500

Result = 100

Therefore, 20% of 500 is 100.

2. Calculate What Percentage One Number Is of Another

To find what percentage one number represents of another, use:

Percentage = (Part ÷ Total) × 100

Example:

A student scores 360 marks out of 500.

Percentage = (360 ÷ 500) × 100

= 0.72 × 100

Result = 72%

The student has scored 72% marks.

3. Calculate Percentage Increase

Percentage increase measures how much a value has increased compared with its original value.

Formula:

Percentage Increase = [(New Value − Original Value) ÷ Original Value] × 100

Example:

Suppose a salary increases from ₹30,000 to ₹36,000.

Increase = ₹36,000 − ₹30,000 = ₹6,000

Percentage Increase = (6,000 ÷ 30,000) × 100

Result = 20%

The salary has increased by 20%.

4. Calculate Percentage Decrease

Percentage decrease measures how much a value has reduced compared with its original value.

Formula:

Percentage Decrease = [(Original Value − New Value) ÷ Original Value] × 100

Example:

Suppose a product's price decreases from ₹2,000 to ₹1,600.

Decrease = ₹2,000 − ₹1,600 = ₹400

Percentage Decrease = (400 ÷ 2,000) × 100

Result = 20%

The product price has decreased by 20%.

5. Find the Original Value

Sometimes you know the final value and the percentage change but want to calculate the original amount.

After a percentage increase:

Original Value = Final Value × 100 ÷ (100 + Increase%)

After a percentage decrease:

Original Value = Final Value × 100 ÷ (100 − Decrease%)

Example:

A product costs ₹800 after a 20% discount.

Original Price = 800 × 100 ÷ 80

Result = ₹1,000

Therefore, the original price was ₹1,000.

How to Use the Online Percentage Calculator

Using an online Percentage Calculator is simple and does not require advanced mathematical knowledge.

Follow these steps:

1. Open the Percentage Calculator tool.

2. Select the type of percentage calculation you want to perform.

3. Enter the required numerical values.

4. Check that the entered numbers are correct.

5. Click the Calculate button, if required.

6. View the percentage result displayed by the calculator.

For example, if you want to calculate 15% of 2,000, enter 15 as the percentage and 2,000 as the total value. The calculator will display 300 as the result.

You can change the input values whenever you need to perform another calculation.

Frequently Asked Questions (FAQs)

1. What is a Percentage Calculator?

A Percentage Calculator is an online tool that calculates percentages, percentage increases, percentage decreases and the relationship between two numbers.

2. How do I calculate a percentage manually?

Divide the part by the total and multiply the result by 100. For example, 40 out of 200 equals 20%.

3. How do I calculate 10% of a number?

Divide the number by 10. For example, 10% of 500 is 50.

4. How do I calculate percentage increase?

Subtract the original value from the new value, divide the difference by the original value and multiply by 100.

5. How do I calculate percentage decrease?

Subtract the new value from the original value, divide the difference by the original value and multiply by 100.

6. Can I use a Percentage Calculator for exam marks?

Yes. Enter your obtained marks and total marks to calculate your examination percentage.

7. Is percentage the same as percentage points?

No. Percentage points measure the direct difference between two percentage values. For example, an increase from 40% to 50% is a rise of 10 percentage points, but a 25% relative increase.
