Yield on cost (YOC) measures how much dividend income you are earning relative to what you originally paid for your shares — not their current market price. It is a metric used almost exclusively by long-term, buy-and-hold dividend investors to track how their income has grown over time. For patient investors who hold dividend-growth stocks for decades, YOC can reach levels that seem remarkable compared to what the stock currently yields to new buyers.
The yield on cost formula
The key difference from standard dividend yield is the denominator: yield on cost uses your cost basis — what you actually paid — not today's market price. This makes YOC a personal metric; it will be different for every investor who bought at a different price.
A concrete example
You buy shares of a dividend-growth company in 2015 at $40 per share. At the time, it pays $1.20 per share annually — a yield of 3%. Over the next decade the company steadily raises its dividend. By 2025, it is paying $2.80 per share annually. The stock now trades at $90, so its current yield on that price is about 3.1% — roughly the same as when you bought it.
But your yield on cost is very different:
A new investor buying this stock today gets 3.1% yield. You have been compounding for a decade and your effective income rate is 7%. This gap widens further every year that the company continues raising its dividend — a powerful demonstration of why long-term dividend growth investing rewards patience.
Why yield on cost matters
YOC serves as a personal income scorecard. Tracking it over time tells you whether a long-term holding is delivering the dividend income growth you expected when you bought it. A consistently rising YOC is one of the clearest signals that a dividend-growth investment strategy is working as intended.
It also provides psychological anchoring — knowing your real effective yield helps long-term investors stay the course during market volatility. If you bought a stock at $40 and it is now at $75, you might be tempted to sell. But if your YOC has risen from 3% to 6% and the company continues raising its dividend reliably, selling means giving up an income stream that would be very expensive to replace at today's prices.
Where yield on cost can mislead
YOC reflects the past — it does not predict the future. This creates a cognitive trap some investors fall into: holding a deteriorating company partly because their "YOC is 12%" sounds impressive, when in reality the business fundamentals have weakened and a dividend cut may be coming.
A high YOC built over many years does not protect you from a dividend cut. The relevant question is always whether the company can sustain and grow its dividend from today forward — not what it has done in the past. Regularly checking the payout ratio and earnings trend is more important than admiring a high YOC figure.
YOC is also not a useful comparison metric between stocks. Telling someone your YOC on Company A is 8% means nothing without knowing your purchase price, holding period, and how dividends have grown. It is a metric about your relationship with a specific investment, not a universal quality rating.
YOC and DRIP compounding together
When you combine a DRIP with a dividend-growth stock, YOC grows even faster than the dividend alone. Here is why: each reinvested dividend purchases more shares at the prevailing market price. Those additional shares then receive all future (and growing) dividends. Your total cost basis rises with each reinvestment, but so does your total share count and income.
Over time, the compounding effect of both rising dividends and a growing share count through DRIP creates what many call the "dividend snowball" — where income growth accelerates far beyond what simple dividend growth alone would produce.
This is why the DRIP breakdown in DivSprout's DRIP Calculator shows effective yield on cost for each projected year — so you can see how rapidly your personal income rate grows relative to what you originally invested, as both the dividend and your share count increase simultaneously.
Real-world YOC examples from dividend growth investing
Among the most cited examples of extreme long-term YOC are investors who purchased shares of companies like Johnson & Johnson, Coca-Cola, or Procter & Gamble in the 1980s or 1990s. Investors who bought Coca-Cola in the early 1990s at prices below $5 per split-adjusted share and held through decades of dividend growth are estimated to be earning YOC rates well above 50% on their original investment — meaning the company pays them back more than half their original investment in dividends every year.
These are extreme examples from exceptional holding periods, but they illustrate the underlying principle: dividend growth compounded over long time horizons produces income rates that appear impossible when viewed through the lens of today's market price.
How to calculate your own yield on cost
To calculate YOC for any holding in your portfolio:
- Find your average cost basis per share — this is your purchase price, or if you bought multiple times, the weighted average of all purchase prices.
- Find the current annual dividend per share — check the investor relations page of the company or your brokerage's dividend information.
- Divide the current annual dividend by your cost basis and multiply by 100.
Example: You bought 50 shares at $55 each (total cost $2,750). The stock now pays $2.20 per share annually. Your YOC = ($2.20 ÷ $55) × 100 = 4.0%.
How to think about a good yield on cost
There is no universal benchmark — YOC depends entirely on how long you have held the investment, what the starting yield was, and how fast dividends have grown. As a rough frame of reference: if you bought a stock at a 3–4% yield and hold it for 10–15 years in a company growing dividends at 6–8% per year, a YOC of 7–12% is achievable. YOC in the double digits over very long holding periods is common in the best-known dividend growth stories.
For investors just starting out, the most actionable takeaway is this: buy quality dividend-growth companies at reasonable yields, enable DRIP, and let time do the heavy lifting. The YOC you will have in 15 years is largely determined by the quality and consistency of the dividend growth you select today.
Frequently asked questions
There is no universal benchmark — it depends on your holding period and starting yield. As a rough guide, a YOC of 7–10% after 10–15 years of holding a quality dividend-growth stock represents strong performance. Many long-term dividend investors aim to see YOC double or triple their original purchase yield within a decade.
Standard dividend yield uses the current market price as the denominator. Yield on cost uses your original purchase price. The two numbers are the same at the moment you buy; they diverge as the stock price changes and the dividend grows over time. YOC is a personal metric — it is different for every investor who bought at a different price.
Yes. When you reinvest dividends through a DRIP, you acquire more shares at the current market price. Each new lot of shares has its own cost basis. Your overall portfolio yield on cost is the weighted average across all your purchase lots — including DRIP purchases. DRIP accelerates the growth of your total income even as it gradually adjusts your blended cost basis upward.
Not necessarily. A high YOC means you are receiving excellent income relative to your original investment. If the company remains fundamentally sound and continues growing its dividend, holding is often the right choice. However, high YOC should not be a reason to avoid selling if the business has deteriorated — assess the company's current fundamentals, not just your historical return.
