What Is a Rate of Increase?

The rate of increase measures how much a value has grown compared to its original amount. It is usually expressed as a percentage.

In simple terms, it tells you:

“How much bigger something has become compared to where it started.”

For example:

If a product price increases from $100 to $120, the increase is 20%.
If a company’s revenue grows from $50,000 to $75,000, the growth rate is 50%.

Knowing the rate of increase helps you understand growth trends, profitability, and financial progress.
