Growth Rate Formula:
| From: | To: |
The growth rate formula calculates the compound annual growth rate (CAGR) between two values over a specified number of periods. It provides the constant rate of return that would be required for an investment to grow from its beginning value to its ending value.
The calculator uses the growth rate formula:
Where:
Explanation: The formula calculates the geometric progression ratio that provides a constant rate of return each period over the entire time span.
Details: Growth rate calculation is essential for investment analysis, business planning, economic forecasting, and comparing the performance of different investments or business units over time.
Tips: Enter the starting value, ending value, and number of periods. All values must be positive numbers. The result will be displayed as a percentage representing the compound annual growth rate.
Q1: What is the difference between simple and compound growth rate?
A: Simple growth rate calculates linear growth, while compound growth rate accounts for the effect of compounding over multiple periods.
Q2: Can this formula be used for negative growth?
A: Yes, the formula works for negative growth (decline) as well. The result will be a negative percentage.
Q3: What time periods can be used?
A: The formula works for any time period (days, months, years) as long as the period count is consistent.
Q4: How accurate is this growth rate calculation?
A: This provides the smoothed annual growth rate assuming constant compounding, which is ideal for comparing investments with different time horizons.
Q5: What are common applications of growth rate calculation?
A: Investment analysis, revenue growth tracking, population growth studies, economic indicator analysis, and business performance evaluation.
