5-Year Growth Rate Calculator
This calculator helps you determine the average annual growth rate over a 5-year period. This metric is crucial for understanding the performance of investments, business revenue, or any metric that is expected to increase over time.
Understanding the 5-Year Growth Rate
The 5-year growth rate is a way to measure how much a value has increased over a specific five-year period, expressed as an average annual percentage. It's a fundamental metric used in finance, economics, and business to assess performance and project future trends.
How it's Calculated:
The formula used is the Compound Annual Growth Rate (CAGR) formula, simplified for a fixed 5-year period:
CAGR = [ (Ending Value / Starting Value) ^ (1 / Number of Years) ] – 1
Where:
- Ending Value is the value of the investment or metric at the end of the period.
- Starting Value is the value at the beginning of the period.
- Number of Years is the duration of the period (in this case, fixed at 5).
A positive growth rate indicates an increase in value, while a negative growth rate signifies a decrease.
Why it's Important:
The 5-year growth rate provides a smoothed-out view of growth, ignoring volatility within the period. This makes it easier to compare performance across different investments or businesses over the same timeframe.
Example:
Let's say you invested $10,000 (Starting Value) in a stock, and after 5 years, its value grew to $18,000 (Ending Value).
Using the calculator with these values would show the average annual growth rate. Plugging into the formula:
CAGR = [ ($18,000 / $10,000) ^ (1 / 5) ] – 1
CAGR = [ (1.8) ^ 0.2 ] – 1
CAGR = [ 1.1247 ] – 1
CAGR ≈ 0.1247 or 12.47%
This means your investment grew by an average of approximately 12.47% each year over the 5-year period.
