Dividend Yield - What is it? How to calculate?

Dividend yield is the metric most dividend investors reach for first, because it converts a dividend payment into a percentage that can be compared across companies, across sectors and against a bond yield. It is also the metric most often misread, because a high yield can signal a generous company or a falling share price, and the number alone does not say which.

Key takeaways

• Dividend yield is a stock's annual dividend per share divided by its current share price, expressed as a percentage.
• Dividend yield is calculated as annual dividend per share divided by current share price, so a $2 annual dividend on a $40 stock is a 5% dividend yield.
• Dividend yield moves inversely with share price: if the dividend is unchanged and the price falls, dividend yield rises, which is why an unusually high yield often reflects a falling price rather than a generous payout.
• Trailing dividend yield uses the dividends actually paid over the past 12 months, so it is backward-looking and does not promise the same income next year.
• Dividend yield measures income against today's market price, while yield on cost measures the same dividend against what you originally paid, and the payout ratio measures the dividend against company earnings.

What is dividend yield?

Dividend yield is a financial ratio that measures a company's annual dividend as a percentage of its current share price. It tells you what income rate you would earn on money invested at today's price, assuming the dividend stays the same.

Dividend yield is quoted as a percentage so that income can be compared across investments of very different share prices. A $500 stock paying $10 a year and a $50 stock paying $1 a year both yield 2%, so the dollar amount of the dividend on its own says nothing useful.

Dividend yield changes every time the share price moves, even when the company has not changed its dividend at all. That is the single most important property of the ratio: the dividend sets the numerator and the market sets the denominator.

How is dividend yield calculated?

Dividend yield is calculated by dividing the annual dividend per share by the current market price per share, then multiplying by 100 to express the result as a percentage.

Dividend Yield = (Annual Dividend Per Share / Current Share Price) x 100

You need exactly two inputs:

1. Annual dividend per share. The total dividend paid on one share over a year. For a company paying quarterly, add the four quarterly payments together; do not use a single quarter.
2. Current share price. The market price of one share right now.

For example, a company that pays an annual dividend of $2 per share while its stock trades at $40 has a dividend yield of $2 / $40 = 5%. Buy at $40 and, if the dividend holds, each share returns $2 of income a year.

Now hold the dividend constant and let the price fall to $25. The dividend yield becomes $2 / $25 = 8%. Nothing improved about the business; the yield rose only because the denominator shrank. Doing this arithmetic across a whole portfolio, in several currencies and at more than one broker, is where it becomes tedious. Portseido tracks dividends for every holding and reports dividend yield and yield on cost automatically from your transaction history, so the figures stay current without a spreadsheet.

What is a good dividend yield?

A dividend yield between roughly 2% and 5% is the range most established dividend payers fall into, and it is generally treated as healthy. Anything much above that band deserves a look at why, and anything below it usually means the company is retaining earnings rather than distributing them.

There is no universal good number, because dividend yield varies systematically by sector and by interest rates. Utilities and consumer staples habitually yield more than software companies, and when government bond yields rise, investors demand higher dividend yields from stocks to compensate for the extra risk.

Is a high dividend yield good?

A high dividend yield is not automatically good, because dividend yield rises both when a company increases its dividend and when its share price falls. The second cause is far more common at the extreme end of the range.

Two things determine whether a high dividend yield is worth having:

• Sustainability. A dividend is only income if it keeps being paid. Check the company's profit margins, free cash flow and dividend payout ratio, which measures what share of earnings the dividend consumes. A payout ratio above 100% means the company is paying out more than it earns, which cannot continue indefinitely.
• Reinvestment. A company distributing most of its profit is not funding future growth with it. That can be perfectly rational for a mature business, but it caps how fast the dividend itself can grow.

The trap has a name: a yield trap is a stock whose dividend yield looks generous only because the market has already marked the price down in anticipation of a dividend cut. When the cut arrives, the investor is left with both a lower income and a capital loss.

Is dividend yield backward-looking or forward-looking?

Dividend yield as published by most financial websites and dividend trackers is backward-looking, because it uses the dividends actually paid over the previous 12 months. That figure describes what a holder received last year, not what a buyer will receive next year.

Two versions of the ratio are in common use:

• Trailing dividend yield. The sum of dividends paid over the past 12 months divided by the current share price. Factual, but stale if the company has just changed its dividend.
• Forward dividend yield. The expected dividend over the next 12 months, usually the most recent declared payment annualised, divided by the current share price. More relevant to a buyer, but it rests on an estimate.

Neither version is a promise. A company can cut, suspend or raise its dividend at any time, so treat dividend yield as a starting point for research rather than a rate of return you have been guaranteed.

Dividend yield vs yield on cost vs payout ratio

Dividend yield, yield on cost and the dividend payout ratio all involve the same dividend, but each divides it by something different, so each answers a different question.

A worked comparison makes the difference concrete. Suppose you bought shares several years ago at $50, when the company paid $1.50 a share, a 3% dividend yield at the time. The company has since raised the dividend to $3.50 a share and the price has risen to $100.

• Dividend yield today is $3.50 / $100 = 3.5%. That is what a new buyer gets.
• Your yield on cost is $3.50 / $50 = 7%. That is what your original $50 now earns.
• If the company's earnings per share are $7, the payout ratio is $3.50 / $7 = 50%, telling you the dividend uses half of profits.

Dividend yield is the metric for deciding what to buy. Yield on cost is the metric for seeing how a long-held position's income has grown. The payout ratio is the metric for judging whether the dividend can survive.

Frequently asked questions

How often is dividend yield updated?

Dividend yield changes continuously during market hours, because the current share price in the denominator changes with every trade. The dividend in the numerator changes only when the company declares a different payment, typically once a quarter or once a year. A quoted dividend yield is therefore a snapshot tied to a specific share price.

Do I need to own a stock on a particular date to receive the dividend?

Yes. You must own the shares before the ex-dividend date to receive the upcoming payment. Buying on or after the ex-dividend date means the dividend goes to the previous owner. Dividend yield says nothing about eligibility; it is only the ratio of annual dividend to price.

Can dividend yield be negative?

No. Dividend yield cannot be negative, because neither a dividend payment nor a share price can be negative. The lowest possible dividend yield is 0%, which is what a company that pays no dividend has. Total return can be negative when the share price falls further than the dividend income received, but the yield ratio itself cannot.

Do ETFs and funds have a dividend yield?

Yes. An ETF or mutual fund distributes the dividends it collects from its underlying holdings, and its dividend yield is those distributions over the past 12 months divided by the fund's current price. Fund yields are quoted net of the fund's expense ratio, so the yield you receive is slightly lower than the weighted average yield of the holdings.

Should I pick stocks by dividend yield alone?

No. Dividend yield ignores dividend growth, payout sustainability and total return. A 2% yield growing 10% a year overtakes a static 5% yield within roughly a decade, and a high yield frequently precedes a dividend cut. Read dividend yield alongside the payout ratio, the dividend growth record and the company's cash flow.
