What Is Percentage Change?

Percentage change measures the relative change between two values. It is widely used in finance, economics, and mathematics to track changes over time, such as stock prices, product prices, or other quantities.

How to Calculate Percentage Change?

The formula for percentage change is:

\[ \text{Percentage Change} = \frac{\text{Final Value} - \text{Initial Value}}{|\text{Initial Value}|} \times 100 \]

This calculator simplifies finding the percentage increase or decrease of any quantity.

Example 1: Percentage Increase

Suppose the price of a mobile increases from $1000 to $1200.

Initial price = $1000
Final price = $1200

Calculation:

\[ \text{Percentage Change} = \frac{1200 - 1000}{1000} \times 100 = 20\% \]

The price increased by 20%.

Example 2: Percentage Decrease

Suppose the price of a car decreases from $5000 to $4500.

Initial price = $5000
Final price = $4500

Calculation:

\[ \text{Percentage Change} = \frac{4500 - 5000}{5000} \times 100 = -10\% \]

The negative sign indicates a 10% decrease in price.

Example 3: Another Decrease

The price of a refrigerator drops from $2000 to $1800.

Calculation:

\[ \text{Percentage Change} = \frac{1800 - 2000}{2000} \times 100 = -10\% \]

The price decreased by 10% over the fiscal year.

FAQs

What does percentage change tell you?

It shows the relative increase or decrease of a value compared to its initial value. It is commonly used to track price changes, investments, or other quantities over time.

Example: Calculating percentage change when 25 increases to 45

Initial Value = 25

Final Value = 45

Change = 45 - 25 = 20

Percentage Change = (20 / 25) × 100 = 80%
