What is the Percentage Increase Calculator?

The Percentage Increase Calculator determines the exact percentage growth between two numbers. It is heavily utilized in finance, economics, and business to track stock portfolio gains, revenue growth, and inflation rates.

How It Works (Formula)

To find the percentage increase, you subtract the initial starting value from the final value to find the absolute difference. You then divide that difference by the original starting value and multiply by 100 to convert the decimal to a percent.

$$ \text{% Increase} = \frac{\text{Final} - \text{Initial}}{\text{Initial}} \times 100 $$

The fundamental formula for calculating relative growth.
