What is EPS Growth?

EPS Growth measures the rate at which a company's earnings per share are increasing year over year. Consistent 10-15%+ EPS growth signals a compounding business. Value investors pair EPS growth with the PEG ratio to assess whether growth is priced fairly.

Formula

EPS Growth = (Current EPS - Prior EPS) / |Prior EPS| x 100

EPS Growth as a Compounder Signal

The most powerful wealth-building stocks share a common trait: they compound earnings per share at above-average rates for extended periods. A company growing EPS at 15% annually doubles its earnings every 5 years. Over a 20-year holding period, that is 16x earnings growth -- which tends to drive 16x stock price appreciation if the valuation multiple stays constant.

The PEG ratio (P/E divided by EPS growth rate) bridges the gap between growth and valuation. A stock trading at 20x earnings with 20% EPS growth has a PEG of 1.0 -- often considered fair value. A stock at 20x earnings with only 5% EPS growth has a PEG of 4.0 -- expensive relative to its growth. Investors use PEG to compare growth businesses on a valuation-adjusted basis.

Calculate the PEG Ratio

The PEG ratio combines EPS growth with P/E to assess whether a growth stock is fairly valued. Explore our DCF Calculator to model future earnings streams.

Frequently Asked Questions

What is EPS growth and why does it matter for stock valuation?+
EPS Growth is the year-over-year percentage increase in earnings per share. It matters because stock prices ultimately follow earnings over the long term -- a company compounding EPS at 15% annually will double its earnings roughly every 5 years. Investors use EPS growth to identify compounders: businesses capable of sustained earnings expansion that rewards patient shareholders.
What constitutes strong EPS growth?+
10%+ annually is considered solid and broadly outpaces nominal GDP growth. 20%+ is strong growth, typical of high-quality businesses with pricing power or expanding margins. Negative EPS growth is a value trap risk -- falling earnings combined with a low P/E ratio may look cheap but is often cheaper still after further earnings deterioration. Context matters: cyclical businesses will show volatile EPS growth, while steady-state businesses should show consistent trends.
How does EPS growth differ from revenue growth?+
EPS can grow faster than revenue through margin expansion (cutting costs or raising prices) or share buybacks (reducing share count). It can also grow slower if margins compress even as revenue rises. Investors should check whether EPS growth is organic (driven by genuine business improvement) or financial engineering (buybacks, one-time items, tax changes). Sustained margin expansion alongside revenue growth is the highest-quality form of EPS growth.
Why is consistent EPS growth more valuable than sporadic growth?+
Predictability allows compounding to work reliably. Warren Buffett looks for 15+ years of consistent EPS growth as a signal of a durable competitive moat -- a business that can reliably grow earnings through recessions, competitive attacks, and management changes. Sporadic EPS growth, where earnings spike and collapse, suggests a cyclical business or one dependent on one-time factors rather than a structural competitive advantage.
