The formula
Annual dividends per share ÷ Current share price × 100 = Dividend yield
If a stock trades at $80 and pays $3.20 per year in dividends, the yield is 4%. If the price rises to $100, the yield drops to 3.2% even though the dividend payment itself didn't change.
What yield actually tells you
Yield is a snapshot of income relative to price — nothing more and nothing less. It tells you how much cash you collect per dollar invested today. It says nothing about whether that income is growing, sustainable, or likely to continue.
That distinction matters enormously in retirement planning. Two funds both yielding 4% can have almost nothing else in common. One might be a quality dividend growth fund where underlying companies raise payouts 8% per year. The other might be a struggling business with a rising yield caused entirely by its falling stock price.
The dividend trap
A suspiciously high yield — anything above 6 or 7% on an individual stock, especially during market stress — often signals that the market expects the dividend to be cut. When investors sell a stock because they doubt the dividend, the price falls and the yield rises. This creates a number that looks attractive but is often a warning.
This is called a dividend trap: chasing yield without checking whether it is sustainable.
Yield vs yield on cost
Once you've held a position for several years, the current yield matters less than your personal yield on cost — the dividend divided by what you actually paid. If you bought a stock at $40 and it now pays $3 per year, your yield on cost is 7.5% even if today's current yield at $80 is only 3.75%.
Yield on cost is the number that tells you how well your original investment is compounding over time. See yield on cost for more.
