The Annual Growth Rate (AGR) is a measure used to express the average rate of growth of an investment, company, or economy over a specific period, typically one year. It helps investors and analysts understand how quickly an entity is expanding or contracting. AGR is often calculated using the formula: (\textEnding Value - \textBeginning Value) / \textBeginning Value \times 100\%. AGR can be applied to various contexts, such as the growth of a business's revenue, the increase in a country's Gross Domestic Product (GDP), or the appreciation of an investment's value. Understanding AGR is essential for making informed financial decisions and assessing performance over time.
