The 10/10 Rule: Why Dividend Growth Rates Beat High Starting Yields

Income investing has an obvious trap built into it. Sort any list of dividend stocks by yield, and the top of the screen looks like free money: 6%, 7%, 8% payouts, on offer today. Meanwhile, some of the most decorated dividend payers in the market — companies with fifty- and sixty-year records of annual raises — sit near the bottom of that sort, yielding less than 1%.

The 10/10 Rule is the mental model that explains why experienced income investors so often buy from the bottom of that list. In its simplest form, the rule says: a dividend growing at roughly 10% a year, sustained for roughly 10 years, will multiply itself about 2.6 times — and the compounding doesn't stop at year ten. The stream a stock pays a decade from now matters more than the yield printed on it today.

Dividend Velocity: The Formula Behind the Rule

The engine underneath the rule is a single expression:

Dₙ = D₀ × (1 + r)ⁿ

where D₀ is today's dividend per share, r is the annual growth rate, and n is the number of years. It is the same compound-interest math that governs everything else in finance, applied to the payout itself. (For the formal definition of a dividend and related terms, the investor.gov dividend glossary is the primary reference.)

What makes this formula powerful for income investors is that the purchase price is fixed at the moment of purchase, while the dividend keeps moving. That ratio — this year's dividend divided by the original purchase price — is Yield on Cost, and it is the number the 10/10 Rule is really about.

A Worked Example: Watching Yield on Cost Compound

Consider a purely illustrative scenario. (The growth rate here is an assumption chosen to demonstrate the arithmetic, not a figure attributed to any specific company.)

An investor puts $10,000 into a stock at $100 per share — 100 shares — paying $2.50 per share annually. Starting yield: 2.5%. Assume, for illustration, that the company raises the dividend 10% every year.

• Year 1: $2.50/share → $250 of income → yield on cost 2.5%
• Year 5: $2.50 × 1.10⁴ ≈ $3.66/share → $366 → YOC 3.66%
• Year 10: $2.50 × 1.10⁹ ≈ $5.90/share → $590 → YOC 5.9%
• Year 11: $2.50 × 1.10¹⁰ ≈ $6.48/share → $648 → YOC 6.5%
• Year 15: $2.50 × 1.10¹⁴ ≈ $9.49/share → $949 → YOC 9.5%

The investor never bought another share. The 2.5% position quietly became a nearly 9.5% yielder — measured against the original cost — because the payout itself compounded. Push the same illustrative assumption one more year and yield on cost crosses 10%: the "10/10" destination.

Against this, place a flat payer: a stock yielding 5% at purchase that never raises its dividend. Same $10,000, $500 a year, every year, forever.

The Counter-Intuitive Part: The Grower Loses for Over a Decade

Here is what most presentations of this rule skip, and it is the single most important thing to understand about it.

Run the two streams side by side under the illustrative assumptions above. The flat 5% payer delivers more income every single year until roughly year nine, when the grower's annual payment finally overtakes it ($2.50 × 1.10⁸ ≈ $5.36 vs. $5.00 per share). And on a cumulative basis — total dollars collected since day one — the flat payer stays ahead until around year fourteen.

In other words, the dividend-growth strategy is a wager that spends more than a decade behind before it wins. That is the counter-intuitive core of the 10/10 Rule: choosing growth over yield is not a clever arithmetic trick that pays off immediately; it is a deliberate trade of the first decade's income for every decade after it. Past year fourteen in this illustration, the gap flips and then widens relentlessly — the grower's payment keeps compounding while the flat payer's stays frozen, and inflation erodes the purchasing power of that frozen check a little more each year. A high yield that never grows is, in real terms, a slowly shrinking one.

This also reframes why very low current yields on elite dividend stocks are often a sign of success rather than stinginess. A durable raiser tends to see its share price bid up alongside its dividend, which mechanically presses the current yield down even as long-term holders' yield on cost climbs.

The Archetypes: Dover and Cintas

Theory needs names attached. Two companies in Asset Trend Reports coverage embody the low-yield, high-durability profile the rule favors.

Dover carries a 68-year raise streak — the longest in Asset Trend Reports coverage — which places it deep inside the Dividend Kings, the club of companies with 50+ consecutive annual increases. Its 0.98% current yield looks unremarkable until it is read alongside the payout ratio: at 25.9%, Dover distributes barely a quarter of its earnings. That is an enormous cushion. A company paying out so little of what it earns has decades of room to keep raising the dividend even through earnings downturns, which is precisely how a streak survives 68 years of recessions, oil shocks, and rate cycles. Its Dividend Safety Score of 100/100 — a 0–100 scale built from the raise streak (up to 50 points) and payout coverage (up to 50 points) — reflects both halves of that durability.

Cintas tells a similar story with a different engine. Its 42-year streak and 37.3% payout ratio earn it a 92/100 Safety Score, and the business behind the dividend is unusually well-suited to compounding: recurring, contract-based revenue from uniform rental and facility services. Customers sign up and keep paying, quarter after quarter, which is exactly the kind of cash-flow visibility that lets a board approve raise number forty-three without losing sleep.

Neither stock will ever top a yield-sorted screen at under 1%. Both are exactly what the 10/10 Rule tells investors to look for: long verified streaks, low payout ratios, and business models built for repetition.

What the Rule Actually Screens For

Stripped to its essentials, the 10/10 Rule is less a formula than a filter with three questions:

1. Is the streak long? A multi-decade record of raises is evidence of management commitment and business resilience that no single year's numbers can fake.
2. Is the payout ratio low? Dover's 25.9% and Cintas's 37.3% are the fuel gauge. A low ratio means future raises can come from expanding the payout, not just growing earnings.
3. Is the revenue durable? Contract-based, recurring, essential — the qualities that let the compounding run uninterrupted.

A dividend screener sorted by Safety Score rather than by yield surfaces exactly this profile, inverting the trap described at the top of this piece. The highest scores cluster where streaks are long and payouts are conservative — and, not coincidentally, where current yields often look small.

The rule's final lesson is temperamental rather than mathematical. The arithmetic of Dₙ = D₀ × (1 + r)ⁿ is available to anyone; the fourteen years of patience in the worked example above is what most income investors are actually short of.
