How to Calculate Dividend Yield: Which Dividend and Share Price to Use
Calculate dividend yield by matching annual dividends per share with the appropriate share price. Hypothetical examples show how historical and expected dividends, current prices, and purchase costs change the result.
Dividend yield is annual cash dividends per share divided by a reference share price. Record both the period covered by the dividend and the date of the share price alongside the figure so you can compare stocks. A yield calculated from dividends received in the past does not guarantee future returns.
Use a full year of dividends in the numerator
For a company that pays quarterly dividends, add the four per-share payments covering the same period. Automatically multiplying the latest payment by four can misrepresent special dividends or increases made during the year. Distinguish a display showing only the year-end dividend from one showing the annual total. First check the payment rounds and share class in the company’s IR dividend history, and keep confirmed amounts separate from estimates that have not yet been decided.
Current yield and yield on cost answer different questions
Yield based on the current price helps compare the dividends available from investing the same amount today. Yield based on the purchase price describes the dividend stream relative to the capital originally invested. Buying cheaply a long time ago does not reduce the opportunity cost of the capital tied up today. When deciding whether to hold, compare alternatives using the current market value; when planning account cash flows, use the actual number of shares entitled to the dividend.
Distinguish the pretax ratio from cash actually received
The dividend per share disclosed by a company is not the amount credited after an individual investor’s taxes and transaction costs. For foreign stocks, align the dividend currency with the purchase currency; changes in the exchange rate at payment also change the cash received in won. Even if you receive a dividend, a larger share-price decline leaves the overall investment return negative. This is why dividend yield should be assessed alongside price changes rather than treated as a guaranteed deposit interest rate.
If you made several purchases at different prices, use the quantity-weighted average acquisition cost as the denominator for a cost-based calculation. Recently purchased shares do not acquire entitlement to dividends whose eligibility dates have already passed. Multiplying annual dividends per share by the current holding can therefore differ from the cash actually received. Keep a supplementary record of eligible shares for each payment.
Worked example
Hypothetical example: If dividends per share for the four quarters are 200 won, 200 won, 250 won, and 250 won, the annual total is 900 won. At a current share price of 18,000 won, pretax dividend yield is 900÷18,000×100=5%. An existing shareholder who paid 15,000 won has a yield on cost of 6%. If all 100 shares are eligible, pretax cash is 90,000 won. The two yields differ because the denominators differ, not because the company pays different dividends.
What to check
- Are any payments missing from or counted twice in the annual total?
- Do the dividend and price refer to the same share class?
- Have you labeled the dividend as confirmed or estimated?
- Have you distinguished current yield from yield on cost?
