EPS Growth Rate Calculator (5-Year CAGR)
Understanding 5-Year EPS Growth
Earnings Per Share (EPS) growth is one of the most critical metrics for stock investors. It represents the portion of a company's profit allocated to each outstanding share of common stock, and its growth indicates the company's ability to generate value for shareholders over time.
The Formula for 5-Year CAGR
To find the average annual growth rate (Compound Annual Growth Rate) between two periods, we use the following mathematical formula:
Where n is the number of growth intervals (which is 4 intervals to get from the start of Year 1 to the end of Year 5).
Why Use a 5-Year Period?
One year of earnings growth can be an anomaly caused by a one-time tax credit or a singular massive sale. A 5-year period is widely considered the "sweet spot" for fundamental analysis because:
- It smoothes out short-term economic fluctuations.
- It covers a typical business cycle.
- It demonstrates a management team's ability to sustain performance.
- It provides enough data to establish a reliable trend for valuation models like the PEGY ratio.
Example Calculation
Suppose a company had the following performance:
- Year 1 EPS: $2.00
- Year 5 EPS: $3.50
The total growth is 75%. However, the CAGR (Annualized Growth) is calculated as:
(3.50 / 2.00)^(1/4) – 1 = 15.02%
This means the company grew its earnings by approximately 15% every year for four consecutive years to reach the final result.
