What is Percentage Increase?

Percentage increase measures how much a value has grown compared to its original amount. It is commonly used to measure salary hikes, business growth, investment returns, population growth, and product price increases.

For example, if a product's price increases from ₹1,000 to ₹1,250, the calculator determines the exact percentage increase.

What is Percentage Decrease?

Percentage decrease indicates how much a value has reduced from its original amount. It is commonly used to calculate shopping discounts, depreciation, business losses, reduced expenses, and price drops.

For example, if an item originally costs ₹2,000 and is now available for ₹1,600, the calculator quickly determines the percentage decrease.

How Does This Calculator Work?

The calculator compares two values:

• Original Value – The starting or previous value.
• New Value – The updated or current value.

It calculates the numerical difference between the two values and then expresses that difference as a percentage of the original value. The result automatically identifies whether it is an increase or a decrease.

Formula Used

The calculator uses the internationally accepted percentage change formula:

Percentage Change = ((New Value − Original Value) ÷ Original Value) × 100

If the result is positive, it represents a percentage increase. If the result is negative, it represents a percentage decrease.

Practical Examples

Example 1: Salary Increase

Your previous salary was ₹40,000 and your new salary is ₹48,000.

Percentage Increase = ((48,000 − 40,000) ÷ 40,000) × 100 = 20%

Example 2: Shopping Discount

An item originally costs ₹2,500 and is now available for ₹2,000.

Percentage Decrease = ((2,000 − 2,500) ÷ 2,500) × 100 = 20% Decrease

Example 3: Investment Growth

An investment grows from ₹1,50,000 to ₹1,80,000.

Percentage Increase = 20%

Example 4: Monthly Expenses
