Lowell Miller's "The Single Best Investment" is the classic text on dividend-growth investing — a book repeatedly cited by DRIP Investor, Seeking Alpha contributors, and the dividend community as the foundation of their philosophy. Miller's thesis is simple: the single best investment is a high-quality, financially strong company with a moderate starting yield and a long record of steadily raising its dividend. Over time, the compounding of a growing dividend stream produces income, capital appreciation, and lower volatility simultaneously. Miller lays out his "High Quality + High Current Yield + High Growth of Yield" formula, shows how to screen for candidates, and explains the behavioral discipline that makes dividend-growth investors among the most resilient in any market cycle.

Key Concepts from The Single Best Investment
The Yield-on-Cost Compounding Engine: Imagine buying a stock that pays you a 3% dividend today, but in 20 years, that same investment is paying you over 20% annually based on what you originally paid. This is the magic of what Lowell Miller calls the "Yield-on-Cost Compounding Engine" – one of the most powerful yet overlooked wealth-building mechanisms in investing.
Here's how this wealth machine works: When you buy a dividend-growing stock, your yield isn't fixed at the initial rate. Instead, it's calculated based on your original purchase price, not the current stock price. If you bought a stock for $100 that paid a $3 annual dividend (3% yield), and that company increases its dividend by 10% each year, something remarkable happens over time.
Let's walk through a practical example. After year one, your dividend grows to $3.30, making your yield-on-cost 3.3%. By year five, you're receiving $4.83 annually – a 4.8% yield on your original investment. Fast-forward to year 15, and you're collecting $12.55 per year, representing a 12.6% yield on your initial $100. By year 20, that dividend has grown to $20.18 annually – a stunning 20.2% return on your original cost, even though the stock might still appear to yield only 3% to new buyers at current prices.
This concept matters because it transforms how you think about dividend investing. While other investors chase high-yield stocks that often cut their dividends, you're building a portfolio of compounding income streams that grow stronger each year. Companies like Coca-Cola, Johnson & Johnson, and Microsoft have delivered this type of dividend growth for decades, quietly enriching long-term shareholders.
The key takeaway is patience and selectivity. This wealth machine only works with high-quality companies that can sustain dividend growth over many years. Miller's insight reveals why the best dividend investments might not be the highest-yielding stocks today, but rather solid companies with modest current yields and strong dividend growth potential. Your future self will thank you for starting this quiet wealth engine as early as possible.
High Quality + High Yield + High Growth: Imagine trying to balance on a three-legged stool where one leg is shorter than the others – you'd quickly topple over. Lowell Miller's investment philosophy works the same way: he argues that truly exceptional dividend-paying stocks must excel in three specific areas simultaneously. His "three-legged test" requires companies to demonstrate high balance-sheet quality, offer a dividend yield above the market average, and maintain a proven track record of consistently raising their dividends over many years.
The beauty of this approach lies in its built-in safety mechanisms and growth potential. High-quality balance sheets mean companies have manageable debt levels, strong cash flows, and financial stability to weather economic storms. The above-market yield requirement ensures you're getting paid well for your patience while you wait for the stock to appreciate. Meanwhile, a long history of dividend increases signals management's confidence in the business and provides a hedge against inflation, as your income stream grows over time.
Consider Johnson & Johnson as a classic example of Miller's ideal investment. The healthcare giant maintains a rock-solid balance sheet with minimal debt relative to its assets, typically offers a dividend yield above the broader market, and has raised its dividend for over 60 consecutive years. During market downturns, investors often flock to such reliable dividend payers, providing downside protection while the growing dividend payments compound your returns.
Miller insists that missing any single leg immediately disqualifies a stock, no matter how attractive the other qualities might be. A high-yielding stock with poor financials could cut its dividend during tough times. A financially strong company with a microscopic yield offers little current income. Even a high-quality, high-yielding stock without a history of raises suggests management may not prioritize shareholder returns or the business may lack growth prospects.
The key takeaway is that exceptional dividend investing requires patience and discipline to find stocks that truly excel in all three areas. While such companies may seem expensive at first glance, Miller argues that paying a fair price for a business that can compound your wealth through both rising share prices and growing dividend payments will ultimately deliver superior long-term returns with lower risk than chasing flashier investments.
Dividend Coverage and Payout Ratio: When you're evaluating dividend-paying stocks, one of the most critical questions you need to ask is: "Can this company actually afford to keep paying me?" This is where dividend coverage and payout ratios become your best friends. These metrics help you separate the truly sustainable dividend payers from the companies that might be living beyond their means and setting you up for disappointment.
The payout ratio is beautifully simple to understand – it's the percentage of a company's earnings (or free cash flow) that gets paid out as dividends. For example, if a company earns $2 per share and pays a $1 dividend, that's a 50% payout ratio. The coverage ratio flips this around, showing you how many times over the company could pay its current dividend with available cash flow. A coverage ratio of 2.0 means the company earns twice what it needs to cover the dividend, providing a comfortable cushion.
As Lowell Miller emphasizes, payout ratios above 80% should raise red flags for most companies. When a business is paying out nearly all its earnings as dividends, there's little room for error if business conditions deteriorate. Consider a hypothetical tech company with a 90% payout ratio – if their earnings drop by just 20% due to market conditions, they're suddenly paying out more than they earn, which is unsustainable.
There are important exceptions to watch for, particularly with REITs and utilities. These sectors often operate with higher payout ratios by design – REITs are legally required to distribute most of their income, while utilities typically maintain stable, predictable cash flows that allow for higher payouts. However, even within these sectors, ratios consistently above 100% should concern you.
The key takeaway is to always look under the hood before falling in love with a high dividend yield. A 8% yield might look attractive, but if the company is paying out 95% of its earnings to maintain that dividend, you're likely looking at a dividend cut waiting to happen. Focus on companies with payout ratios between 40-70% – they offer the sweet spot of attractive current income while retaining enough earnings to grow the business and weather inevitable storms.
Reinvestment Discipline: Reinvestment discipline is the practice of automatically reinvesting your dividend payments back into the same stocks, especially during market downturns when share prices are depressed. In "The Single Best Investment," Lowell Miller argues that this seemingly simple strategy is one of the most powerful wealth-building tools available to individual investors. The key insight is that when you reinvest dividends during market crashes or bear markets, you're essentially buying more shares at bargain prices, which supercharges your long-term returns through compound growth.
The magic happens because of basic math and human psychology working in your favor. When stock prices fall, your dividend dollars purchase more shares than they would during bull markets. Miller emphasizes that this creates a "snowball effect" – you own more shares, which generate more dividends, which buy even more shares at low prices. Most investors do the opposite, panicking and selling during downturns, but reinvestment discipline forces you to do the mathematically optimal thing: buy more when prices are cheap.
Consider Johnson & Johnson during the 2008 financial crisis. While the stock price dropped nearly 20%, investors who maintained their dividend reinvestment plans (DRIPs) were automatically purchasing additional shares at steep discounts. Those reinvested dividends bought significantly more shares than they would have in 2007, and when the market recovered, these investors owned substantially more shares generating even higher dividend income. This demonstrates why Miller advocates for automatic DRIPs – they remove emotion and timing decisions from the equation.
The practical application is straightforward: set up automatic dividend reinvestment plans through your broker or directly with companies. Miller specifically recommends sticking with this strategy "through thick and thin" because the biggest gains come from reinvesting during the worst market conditions. Many investors make the mistake of turning off DRIPs during downturns, precisely when they should be most aggressive about reinvestment.
The key takeaway is that reinvestment discipline transforms you from someone who merely collects dividends to someone who systematically accumulates wealth-building assets. By automating this process, you remove the temptation to spend dividends or time the market, instead letting mathematical compounding work in your favor over decades. As Miller demonstrates, this patient, disciplined approach often outperforms more complex investment strategies simply by harnessing the power of buying low consistently over time.
The Behavioral Edge: Picture this: You've invested $10,000 in two different stocks. Stock A pays you $300 in dividends each year, while Stock B pays nothing but promises growth. When the market crashes 30%, which investment are you more likely to panic-sell? Most investors hold onto the dividend-paying stock because those quarterly checks provide psychological comfort and tangible proof that their investment is "working," even when share prices fall.
This psychological phenomenon is what Lowell Miller calls "The Behavioral Edge" – the powerful way that regular dividend payments help investors overcome their worst enemy: themselves. While market volatility can trigger our fight-or-flight responses and lead to costly emotional decisions, dividend checks arriving like clockwork create a mental anchor. They transform abstract market movements into concrete, spendable returns that exist regardless of whether your portfolio statement shows red or green.
The numbers tell a compelling story about why this behavioral advantage matters so much. Studies show that the average investor significantly underperforms the market – not because they pick bad investments, but because they buy high during euphoric periods and sell low during panic. However, dividend-focused investors tend to exhibit much more disciplined behavior. When you receive $75 every quarter from a reliable dividend payer, you're less likely to obsess over daily price swings or make rash decisions based on market noise.
Consider Johnson & Johnson, which has increased its dividend for 60 consecutive years. During the 2008 financial crisis, while the stock price fell over 20%, shareholders still received their quarterly payments – and many used those dividends to buy more shares at lower prices. Those who stayed the course and reinvested dividends saw their wealth compound significantly as the market recovered, while investors who sold in panic locked in permanent losses.
The behavioral edge isn't just about feeling good – it's about creating the psychological conditions that allow compound interest to work its magic. By providing regular, tangible returns that don't depend on market sentiment, dividend stocks help investors develop the most crucial skill in wealth building: the ability to stay invested through inevitable periods of volatility and uncertainty.

Frequently Asked Questions
What is The Single Best Investment book by Lowell Miller about?
The Single Best Investment by Lowell Miller is a classic text on dividend-growth investing that argues high-quality companies with moderate yields and long records of raising dividends are the best investments. Miller presents his formula of High Quality + High Current Yield + High Growth of Yield to help investors identify stocks that can provide income, capital appreciation, and lower volatility over time.
What is Lowell Miller's dividend growth investing strategy?
Miller's strategy focuses on investing in financially strong companies that have a history of steadily raising their dividends year after year. The approach relies on the compounding effect of growing dividend streams, which simultaneously produces increasing income, capital appreciation, and reduced portfolio volatility compared to other investment strategies.
How do you screen for dividend growth stocks according to The Single Best Investment?
According to Miller, investors should screen for companies that meet three criteria: high quality (strong financials), high current yield (reasonable starting dividend), and high growth of yield (consistent history of dividend increases). The book provides specific guidance on evaluating dividend coverage ratios, payout ratios, and company fundamentals to identify suitable candidates.
What is yield on cost in dividend investing?
Yield-on-cost is the annual dividend payment divided by your original purchase price, which increases over time as companies raise their dividends. Miller describes this as the "compounding engine" of dividend growth investing, where your effective yield on the original investment grows substantially over the years, even if the stock price doesn't appreciate significantly.
Is The Single Best Investment by Lowell Miller worth reading?
Yes, the book is widely regarded as a foundational text in dividend growth investing and is frequently cited by investment publications like DRIP Investor and contributors on Seeking Alpha. It provides a clear, disciplined framework for dividend investing that has helped many investors build resilient portfolios across different market cycles.
What is dividend coverage ratio and why is it important?
Dividend coverage ratio measures how easily a company can pay its dividends from its earnings, calculated by dividing earnings per share by dividends per share. Miller emphasizes this metric as crucial for identifying sustainable dividend payments and avoiding companies that might cut their dividends during tough times.
How does dividend reinvestment work according to Lowell Miller?
Miller advocates for disciplined dividend reinvestment, where investors automatically use their dividend payments to purchase additional shares of the same stock. This reinvestment discipline amplifies the compounding effect over time, as investors acquire more shares that generate even more dividends in a virtuous cycle.
What are the best dividend growth stocks according to The Single Best Investment?
While Miller doesn't recommend specific stocks, he outlines criteria for identifying quality dividend growers: companies with strong balance sheets, consistent earnings growth, reasonable payout ratios, and long histories of annual dividend increases. The book teaches readers how to evaluate and screen for these characteristics rather than providing a list of recommendations.
What is the behavioral advantage of dividend growth investing?
Miller explains that dividend growth investors tend to be more disciplined and less emotional during market volatility because they focus on growing income streams rather than stock price fluctuations. This behavioral edge helps investors avoid panic selling during market downturns and stick to their long-term investment strategy.
How does dividend growth investing reduce portfolio volatility?
Dividend growth stocks typically experience lower price volatility because they attract income-focused investors who are less likely to trade based on market sentiment. Additionally, the steady income stream from dividends provides a cushion during market declines and reduces the overall portfolio's dependence on capital appreciation alone.
