Dividend yield is one of the most-quoted numbers in investing, but it's also one of the most misunderstood. Because it's a ratio of dividend to price, it changes every time the stock price moves, even if the company hasn't changed its payout at all. Understanding that relationship is key to using yield correctly when comparing stocks.
The Formula
Worked Example
Suppose Stock A trades at $50 per share and pays $2.00 per year in dividends: Dividend Yield = (2.00 ÷ 50) × 100 = 4%. Now suppose Stock B trades at $120 and pays $3.60 per year: Dividend Yield = (3.60 ÷ 120) × 100 = 3%. Even though Stock B pays a larger dollar amount per share, Stock A actually delivers more income relative to what you invested.
| Stock | Price | Annual Dividend | Yield |
|---|---|---|---|
| Stock A | $50 | $2.00 | 4.0% |
| Stock B | $120 | $3.60 | 3.0% |
| Stock A (price drops to $40) | $40 | $2.00 | 5.0% |
Notice the third row: if Stock A's price falls to $40 while the dividend stays at $2.00, the yield jumps to 5% — not because the company is paying more, but purely because the price fell. A sharply rising yield can be a genuine bargain, or a warning sign that the market expects a dividend cut.
Yield vs. Total Return
Dividend yield only captures cash income. A stock could have a modest 1% yield but still be an excellent investment if its share price grows 15% a year. Conversely, a stock with an 8% yield that's losing 20% a year in price is a poor investment overall. Always look at yield alongside price trend, payout ratio, and earnings stability.
