Percentage Increase Calculator

The simple difference is just the final value minus the initial value (e.g., 150 - 100 = 50). Percentage growth puts that difference into context relative to the starting point. A growth of 50 is a 50% increase if you start at 100, but only a 5% increase if you start at 1000.

A negative percentage growth indicates a decrease or decline. If your initial value is 100 and your final value is 80, the calculator will show a -20% growth, meaning the value has decreased by 20%.

Mathematically, you cannot calculate percentage growth from an initial value of zero, as it involves division by zero. In such a case, the growth is considered infinite. This calculator will show a result of 0% and you should assess the absolute increase instead.

You can use it for almost anything! Common uses include: tracking business revenue or user growth, analyzing stock market performance, measuring social media follower increase, monitoring website traffic changes, or even tracking personal fitness goals like weight loss.

Functionally, they are the same. "Percentage growth" is often used when an increase is expected, while "percentage change" is a more neutral term that can refer to either an increase or a decrease. This tool calculates both positive (growth) and negative (decline) changes.

Yes. For example, if your company's profit went from a loss of -$500 to a profit of $200, this calculator would correctly show a 140% growth. The formula uses the absolute value of the initial number as the base to ensure the percentage is calculated correctly.
