Dividend Yield Explained: How to Calculate It (UK)

What dividend yield means

Dividend yield is a company's annual dividend per share divided by its share price, expressed as a percentage. It shows the income return an investor receives relative to the price paid for the share. A share priced at 400p that pays 20p a year in dividends has a yield of 5%.

Dividend yield is a way of comparing the cash income a company pays out with the cost of buying its shares. It is useful because it puts dividends on a common scale: a 20p dividend means something very different on a 100p share than on a 1,000p share, but the yield makes the two directly comparable. Investors often use yield to screen for income-producing shares, to compare a company against its peers, or to judge whether a share offers a reasonable income relative to alternatives such as cash savings or bonds. Yield is not a measure of quality or safety on its own, and it says nothing about whether the dividend will be maintained.

There are two common versions of the figure. A trailing yield uses the dividends actually paid over the last 12 months, divided by the current share price. It is based on facts that have already happened, so it is reliable as a record but backward looking. A forward yield uses a forecast of the next 12 months of dividends, divided by the current price. It is more relevant to what an investor might receive going forward, but it depends on estimates that can prove wrong. Forecasts may be revised, and companies can cut dividends with little warning, so a forward yield should be treated as an expectation rather than a promise.

How to calculate dividend yield

The formula is: dividend yield = annual dividend per share / share price x 100. For example, a 20p annual dividend divided by a 400p share price gives 0.05, which is a 5% yield. The calculation is simple, but the result changes whenever either the dividend or the share price moves.

To calculate the yield, first establish the annual dividend per share. For a trailing yield, add up the dividends paid over the past 12 months. For a forward yield, use the forecast for the coming year. Then divide that figure by the current share price and multiply by 100 to convert the decimal into a percentage. Both figures should be in the same units, so if the dividend is quoted in pence, the share price should also be in pence. The worked example is straightforward: 20p divided by 400p equals 0.05, or 5%. That means an investor buying at 400p would receive income equal to 5% of the purchase price each year, assuming the dividend is maintained.

The second example shows how sensitive the figure is to price. If the share price falls to 250p while the dividend stays at 20p, the yield becomes 20p divided by 250p, which is 0.08, or 8%. The dividend has not changed, but the yield has risen because the price has fallen. This is an important point: a rising yield does not always mean a company is paying more. It can simply mean the market has marked the shares down. Investors comparing yields should check whether a change comes from the dividend or from the price, because the two tell very different stories about a company's prospects.

Why a high yield can be a warning sign

A high yield can be a warning sign because a falling share price inflates the yield even when the dividend is unchanged. If the market expects a dividend cut, the price often falls first, pushing the yield up. This is sometimes called a yield trap: the income looks attractive, but it may not last.

The yield trap arises because the formula divides by the share price. When investors lose confidence in a company, they sell, the price drops, and the yield rises mechanically. A yield that looks unusually high compared with similar companies may therefore reflect doubt about whether the dividend can be sustained. The market is often pricing in a cut before it is announced. Buying purely on the basis of a high yield, without checking why the yield is high, can lead to disappointment if the dividend is reduced or suspended. Cuts are common in downturns, when profits fall and companies choose to preserve cash rather than keep paying out.

One way to test whether a dividend looks sustainable is dividend cover, calculated as earnings divided by the dividend. A cover of 2 means the company earns twice what it pays out, leaving a cushion. A cover below 1 means the company is paying more than it earns, which is generally unsustainable unless it has large cash reserves or a one-off reason. Cover is not a guarantee, because earnings can fall, but it gives a sense of how much room a company has. Investors should also look at the trend in dividends over several years, the strength of the balance sheet, and whether the business generates consistent cash. A high yield backed by solid cover and stable cash flow is very different from a high yield on a struggling company.

Dividend yield vs total return

Total return combines the change in share price with the dividends received, while dividend yield measures only the income component. A share with a 5% yield that falls 10% in price has delivered a negative total return. Reinvesting dividends can compound returns over time.

Dividend yield tells an investor about income, but it does not capture the full picture of what an investment has delivered. Total return adds capital growth or loss to the dividends received, giving a more complete measure of performance. A company might pay a modest dividend but see its share price rise strongly, producing a good total return. Another might pay a high yield while its share price declines, leaving the investor worse off overall. For anyone saving for a goal, total return is usually the more relevant figure, because it reflects the change in the value of the holding as well as the cash it produces.

Reinvesting dividends is a way to build returns over time. When dividends are used to buy more shares, those additional shares can themselves pay dividends, which can then be reinvested again. Over long periods this compounding effect can be significant, although it depends on the returns of the underlying investment and is not guaranteed. Many funds offer accumulation units, which automatically reinvest income rather than paying it out, making the process straightforward. Investors who need income, such as those drawing on a portfolio in retirement, may prefer to take the dividends as cash. The choice between income and accumulation depends on whether the goal is to spend the yield or to grow the pot.

How UK dividends are taxed

In the UK, dividends above the annual dividend allowance are taxable unless the shares are held in an ISA or pension. The dividend allowance is £500 per tax year. The rate paid on dividends above the allowance depends on the investor's income tax band, and HMRC publishes the current rates.

The dividend allowance lets an investor receive up to £500 of dividends in a tax year without paying tax on them. Dividends above that amount are taxed at rates that depend on whether the investor is a basic, higher or additional rate taxpayer. The rates can change, so it is worth checking the current figures on GOV.UK rather than relying on older information. Dividends received inside an Individual Savings Account (ISA) or a pension are not taxed, which makes these wrappers attractive for income investors. The tax treatment depends on individual circumstances and may change in future, so anyone unsure about their position should seek professional advice.

For many investors, holding dividend-paying shares inside an ISA or pension removes the tax question entirely. ISAs have an annual subscription limit, and pensions have their own rules on contributions and access, so the right wrapper depends on the investor's circumstances and goals. Outside these wrappers, dividends count towards the investor's income for tax purposes, and the tax is usually collected through self assessment. Keeping records of dividends received is therefore important for anyone who holds shares outside a tax wrapper. The allowance is per person, so couples can each use their own allowance. Because thresholds and rates are set by government and can be revised, the figures should be confirmed each tax year.

Yield on funds and ETFs

Funds and exchange traded funds (ETFs) publish a yield in their factsheet, usually based on the income distributed over the past 12 months. Investors can choose income units, which pay out the dividends, or accumulation units, which reinvest them. The choice affects cash flow, not the underlying return.

A fund's yield is calculated from the income it receives from the shares or bonds it holds, after costs, relative to the fund's price. Because a fund holds many investments, its yield is usually more diversified than that of a single company, which reduces the risk that one dividend cut derails the income. The figure is published in the fund's factsheet, along with other details such as charges and holdings. Yields on funds can vary over time as the underlying holdings change and as markets move. Investors should check whether the published yield is trailing or forward looking, and whether it is based on distributions actually paid or on an estimate.

The choice between income and accumulation units is mainly about how the investor wants to receive returns. Income units pay out the fund's dividends, providing cash that can be spent or reinvested elsewhere. Accumulation units keep the income inside the fund and reinvest it, which can simplify administration and support compounding. The underlying investments are the same, so the total return before tax is broadly similar, although the timing of any tax liability can differ. For investors using an ISA or pension, the wrapper shelters the income either way. For those holding funds outside a wrapper, accumulation units can create a tax liability on income that has not been received in cash, so it is worth understanding how the units work before choosing.

Frequently asked questions

What is a good dividend yield in the UK?

There is no single good figure. A very high yield can reflect a falling share price or a dividend at risk of being cut, so yield is usually read alongside dividend cover and company results.

How do you calculate dividend yield?

Divide the annual dividend per share by the current share price and multiply by 100. A 20p dividend on a 400p share gives a 5% yield.

Is dividend yield the same as return?

No. Dividend yield measures income only. Total return also includes any rise or fall in the share price.

Are dividends taxed in the UK?

Dividends above the £500 dividend allowance are taxed at rates that depend on your income tax band. Dividends inside an ISA or pension are not taxed.

Why does dividend yield go up when share prices fall?

The yield is the dividend divided by the price. If the price falls and the dividend stays the same, the percentage yield rises.
