What Is Dividend Yield? (And When a High One Is a Trap)
Dividend yield tells you how much income a stock pays out each year relative to its price. It sounds simple - higher is better, right? - but a very high yield is one of the most common traps for new investors.
How dividend yield is calculated
A dividend is a cash payment a company makes to shareholders, usually each quarter. The dividend yield expresses the total annual dividend as a percentage of the current share price:
Dividend yield = Annual dividend per share ÷ Share price
Yield = $4 ÷ $100 = 4%.
If the same $4 dividend came on a $50 stock, the yield would be 8%.
Because it is a ratio, yield lets you compare the income from stocks at very different prices on an equal footing - much as the P/E ratio does for valuation.
Yield moves opposite to price
Here is the part that trips people up: for a fixed dividend, yield rises as the share price falls. The math is unavoidable - a smaller denominator makes the ratio bigger.
The "yield trap"
A yield trap (or dividend trap) is a stock whose yield looks unusually attractive - say, 12% when its peers pay 3% - precisely because the price has collapsed on bad news. The danger is twofold:
- The dividend may be cut. A payout the company can no longer afford often gets reduced or eliminated, and the price frequently falls further when that happens.
- The high yield is temporary. Once the dividend is cut, the yield you were chasing disappears.
This is why an eye-catching yield is a reason to ask questions, not a reason to celebrate. The obvious question: can the company actually keep paying it?
The payout ratio: a reality check
To judge whether a dividend is sustainable, many investors look at the payout ratio - the share of a company's earnings paid out as dividends:
Payout ratio = Dividends ÷ Net income (often expressed per share using EPS).
- A moderate payout ratio suggests the company keeps enough profit to sustain and grow the dividend.
- A payout ratio above 100% means the company is paying out more than it earns - a situation that generally cannot last indefinitely.
What a "good" yield depends on
There is no universal right number. Yield varies a lot by industry - mature utilities and real estate companies typically pay higher yields, while fast-growing firms often pay little or nothing, choosing to reinvest profits instead. A yield only becomes meaningful compared with a company's own history and its sector peers.
The bottom line
Dividend yield is a clean, comparable measure of the income a stock pays relative to its price. But because it moves opposite to price, an unusually high yield can reflect a falling stock and a shaky dividend rather than a bargain. Pairing yield with the payout ratio and the company's broader health turns it from a number that can mislead into one that genuinely informs. As always, this is descriptive context - not a signal to buy or avoid anything.

Frequently asked
How is dividend yield calculated?
Dividend yield is the annual dividend per share divided by the current share price, expressed as a percentage. A stock trading at $100 that pays $4 a year has a yield of 4%, while the same $4 dividend on a $50 stock is an 8% yield. Because it is a ratio, yield lets you compare income from stocks at very different prices on an equal footing.
Why does dividend yield go up when a stock price falls?
For a fixed dividend, yield rises as the price falls because a smaller denominator makes the ratio bigger. So a rising yield is not always good news; if the price is dropping because the business is struggling, the yield climbs purely because of that fall. A very high yield can be the market signalling trouble rather than generosity.

How can I tell if a dividend is sustainable?
Many investors check the payout ratio, the share of a company's earnings paid out as dividends. A moderate ratio suggests the company keeps enough profit to sustain and grow the dividend, while a ratio above 100% means it is paying out more than it earns, which generally cannot last.
