Dividend yield shows the income a share pays relative to its price; the payout ratio shows how much of a company's profit funds that dividend. This guide explains how to calculate both and what counts as sustainable.
A company can pay a generous-looking dividend and still be a poor investment — and a modest dividend can be a sign of real strength. To tell the difference, two simple measures do most of the work: the dividend yield and the payout ratio. One tells you how much income you are getting for the price; the other tells you whether that income is built to last. Here is how to calculate and read both. This is general information, not financial advice.
Dividend yield is the annual dividend a share pays, expressed as a percentage of its current price. It answers a direct question: for every pound I put in, how much income do I get back each year?
The formula is straightforward:
Dividend yield = (annual dividend per share ÷ share price) × 100
A worked example makes it concrete. If a share costs 1000p and pays 50p in dividends over a year, the yield is (50 ÷ 1000) × 100 = 5%. If that same 50p dividend were paid on a 2000p share, the yield would be only 2.5%.
Yield lets you compare the income of different shares on a like-for-like basis, regardless of their price. It is the headline figure income investors reach for first.
Here is the most important lesson for beginners: a very high yield is not automatically a good deal. Look again at the formula. Yield rises if the dividend goes up — but it also rises if the share price falls.
A share price often falls because the market has doubts about the company. So a strikingly high yield can be a symptom of trouble rather than a bargain: the price has dropped because investors fear the dividend will be cut, which mechanically inflates the yield in the meantime. This is sometimes called a value trap.
The practical rule: treat an unusually high yield as a prompt to investigate why, not as a signal to buy. Which is exactly where the second measure comes in.
The payout ratio is the proportion of a company's earnings (profit) that it pays out as dividends. Where yield looks at the dividend relative to the price, the payout ratio looks at it relative to the profit funding it.
Payout ratio = (dividends ÷ earnings) × 100
If a company earns 100p per share and pays 40p as dividends, its payout ratio is 40%. The other 60% is retained — kept in the business to reinvest in growth or held as a buffer.
The payout ratio is, in effect, a sustainability check. It tells you how much room the company has: how comfortably the profit covers the dividend, and how much is left over.
There is no single magic number, but the principles are clear.
| Payout ratio | What it often suggests |
|---|---|
| Low (e.g. under 35%) | Plenty retained; room to grow or raise the dividend |
| Moderate (e.g. 35–60%) | A balance of income now and reinvestment |
| High (e.g. 60–90%) | Generous, but less cushion if profits dip |
| Very high (90%+ or over 100%) | Possibly unsustainable; investigate carefully |
Yield and payout ratio are most powerful side by side, because each covers the other's blind spot:
A healthy income share typically shows a reasonable yield backed by a sustainable payout ratio. A high yield paired with a sky-high payout ratio is a classic red flag — a generous payment the company may struggle to maintain. To see how those payments are scheduled and who qualifies, see our guide to dividend dates, and to understand the different types of payment, read what an interim dividend is.
The same retain-versus-distribute tension that the payout ratio measures sits at the heart of company finance generally — it is closely tied to a firm's share capital and how it chooses to fund itself. And the broader point, that reinvested profit compounds over time, is one reason long-term investors care so much about it; our explainer on how compound interest works shows why.
Companies announce dividends routinely as part of normal reporting. London consultancy CM Beyer, for example, published a notice when it declared an interim dividend for a recent financial period — the kind of disclosure that gives shareholders the figures they need to work out yield and judge the payout for themselves.
Dividend yield shows the income a share pays for its price; the payout ratio shows whether that income is sustainable out of profit. A high yield is not automatically good — it may flag a falling price and a dividend at risk — which is why you read it alongside the payout ratio. A reasonable yield supported by a sustainable payout is the combination that tends to reward patient income investors.
