Yield on Cost: Why Dividend Growth Beats High Yield Over Time
The most powerful force in dividend investing is not the yield you buy at — it is the yield you earn five, ten, and twenty years later. That number is called yield on cost, and it is the primary reason dividend growth investors consistently outperform yield-chasing investors over long holding periods.
The math works like this: If you buy a stock yielding 2.5% today and its dividend grows at 12% annually, your yield on cost after ten years is not 2.5% — it is approximately 7.75% on your original investment. Meanwhile, the stock price has also risen to reflect the higher dividend, adding substantial capital gains on top of the growing income stream.
| Starting Yield | Div Growth Rate | YOC Year 5 | YOC Year 10 | YOC Year 15 |
|---|---|---|---|---|
| 2.5% | 12% / yr | 4.4% | 7.8% | 13.7% |
| 3.0% | 10% / yr | 4.8% | 7.8% | 12.5% |
| 7.0% | 0% / yr | 7.0% | 7.0% | 7.0% |
| 5.0% | 3% / yr (inflation only) | 5.8% | 6.7% | 7.8% |
The growth compounder (2.5% at 12%) matches the static high-yield stock (7%) by year 8. By year 15, it yields nearly twice as much on original cost. And it has also appreciated significantly in price, which the high-yield stock typically has not.
Why growth wins: Companies growing dividends at 10%+ are typically also growing revenues, earnings, and free cash flow at meaningful rates. The dividend growth is a signal of business health. High-yield stocks, particularly those yielding 6–8%, often carry that yield because the market is discounting future cut risk — meaning the price is suppressed, not the dividend elevated. The yield trap is invisible until the cut arrives.
