What is EPS Growth?

Earnings per share (EPS) growth measures how a company’s earnings attributable to each share change over time. Analysts often use CAGR to understand the long‑term, compounded growth rate between a starting EPS and an ending EPS.

CAGR Formula

CAGR = (End / Start)^(1 / Years) − 1

CAGR smooths volatility and shows the steady rate required to grow from Start to End over a given number of years.

Year‑over‑Year (YoY) EPS Growth

YoY Growth = (Current EPS − Prior EPS) / Prior EPS

Use YoY to evaluate short‑term momentum, and CAGR for multi‑year trends.

How to Calculate EPS Growth (Example)

Suppose EPS grew from 2.00 to 3.50 over 5 years.

  1. Compute the ratio End / Start = 3.50 / 2.00 = 1.75
  2. Take the 5th root: 1.75^(1/5) ≈ 1.1185
  3. Subtract 1 and convert to %: (1.1185 − 1) × 100% ≈ 11.85%

CAGR ≈ 11.85% per year.

When to use CAGR

  • • Compare long‑term performance across companies
  • • Remove noise from cyclical earnings swings
  • • Align with multi‑year investment horizons

When to use YoY

  • • Track recent momentum or inflection points
  • • Assess the impact of product launches or cycles
  • • Monitor quarterly or annual reporting periods

Interpreting EPS Growth

Context Matters

  • • Revenue growth and margin expansion support durable EPS growth
  • • Buybacks can boost EPS without improving fundamentals
  • • Cyclical industries may show volatile YoY figures

Rule‑of‑Thumb Ranges

  • • 0–5%: Mature or low‑growth businesses
  • • 5–15%: Healthy growth
  • • 15%+: High growth (verify sustainability)

Frequently Asked Questions

Is EPS growth always good?

Not necessarily. Growth driven by one‑offs or heavy buybacks without cash‑flow support can be low quality. Cross‑check with margins, free cash flow, and leverage.

CAGR vs average YoY?

CAGR shows the compounded rate over a period; average YoY can be skewed by volatility. Use CAGR for long‑term perspective.

What if EPS is negative?

CAGR is not defined across negative values. Consider normalizing periods, using operating metrics, or waiting until EPS turns positive.
