How to Calculate Earnings Per Share (EPS) Growth Rate

Earnings Per Share (EPS) growth rate is one of the most critical metrics used by fundamental investors and equity analysts to evaluate a company's financial health. It measures the percentage increase or decrease in a company's profit allocated to each outstanding share of common stock over a specific period.

The Simple EPS Growth Formula

To calculate the basic Year-over-Year (YoY) growth rate, use the following formula:

EPS Growth Rate = ((Current EPS – Prior EPS) / Prior EPS) × 100

The CAGR Formula for Multi-Year Analysis

When analyzing growth over several years, the Compound Annual Growth Rate (CAGR) provides a more accurate picture by smoothing out volatility. The formula is:

CAGR = [(Ending EPS / Beginning EPS)^(1 / n)] – 1

Where n represents the number of years in the period.

Step-by-Step Calculation Example

Let's assume "TechCore Inc." reported the following earnings:

  • EPS in 2021: $2.00 (Beginning EPS)
  • EPS in 2023: $2.88 (Ending EPS)
  • Period: 2 Years

1. Calculate Total Growth

Total Growth = (($2.88 – $2.00) / $2.00) = 0.44 or 44%.

2. Calculate CAGR

CAGR = [($2.88 / $2.00)^(1 / 2)] – 1
CAGR = [1.44^0.5] – 1
CAGR = 1.20 – 1 = 0.20 or 20% per year.

Why EPS Growth Matters

Investors prioritize EPS growth because it is a primary driver of stock prices over the long term. A company that consistently grows its earnings is typically more valuable than one with stagnant or declining profits. It indicates:

  • Operational Efficiency: The company is managing costs effectively.
  • Revenue Expansion: The company is successfully selling more products or services.
  • Share Buybacks: If the net income stays flat but shares outstanding decrease, EPS will rise.

Limitations of the Metric

While EPS growth is powerful, it shouldn't be used in isolation. Be aware of:

  • Accounting Maneuvers: Non-recurring gains or changes in tax rates can artificially inflate EPS.
  • Dilution: Issuing more shares can lower EPS even if total net income increases.
  • Negative Starting Point: If a company was losing money (negative EPS) in the prior period, the standard percentage growth formula becomes mathematically distorted.
