How to Calculate Dividend Yield and What Makes a Good One
Dividend yield tells you how much income a share pays relative to its price — but a high yield can be a warning sign as often as a reward. Here's how to calculate it and what to look for.
Dividend yield is one of the most-quoted metrics in income investing — but raw yield figures without context can be misleading. Here's how to calculate it correctly and interpret what you find.
The Formula
Dividend Yield % = (Annual Dividend per Share ÷ Share Price) × 100
Example: Vodafone pays 9p dividend per share, price is 75p
Yield = (9 ÷ 75) × 100 = 12%
Example: Unilever pays 52p dividend, price is 3,800p
Yield = (52 ÷ 3,800) × 100 = 1.37%
Forward vs Trailing Yield
Trailing yield: uses last 12 months' actual dividends (historical)
Forward yield: uses next 12 months' forecast dividends (predictive)
Trailing yield is fact; forward yield is an estimate.
Financial data sites may show either — always check which one.
What Makes a Good Yield?
Yield RangeTypical ContextWhat It Often Signals
Below 1%Growth stocksCompany reinvests most profit; no income focus
1–3%Quality dividend payersDividend sustainable; modest income
3–5%Income investing sweet spotSolid yield; worth investigating
5–8%High yield — investigateMay be sustainable or may be distressed
Above 8%Very high — cautionOften a yield trap — see below
The Yield Trap: Why High Yield Is Often a Warning
When a company's share price falls sharply, the yield rises even if the dividend stays the same — because yield = dividend ÷ price. A stock with a 15% yield may look attractive, but the price has often fallen because the market anticipates a dividend cut. If the cut materialises, the investor suffers both a capital loss and a lower dividend.
Company paid 20p dividend, share was 400p → yield 5%
Share price falls to 200p (bad earnings news)
Yield = 20p ÷ 200p = 10% — looks amazing
Then company cuts dividend to 8p
Yield = 8p ÷ 200p = 4% — now just average
Plus investor has a 50% capital loss
This is the yield trap.
Dividend Cover: Checking Sustainability
Dividend Cover = Earnings per Share (EPS) ÷ Dividend per Share
Cover of 2× = company earns twice what it pays in dividends (comfortable)
Cover of 1× = paying out all earnings (risky — no buffer)
Cover below 1× = paying more than it earns (unsustainable)
Example: EPS = 30p, dividend = 15p
Cover = 30 ÷ 15 = 2× ✓
Example: EPS = 12p, dividend = 15p
Cover = 12 ÷ 15 = 0.8× ⚠️ unsustainable
Total Return vs Yield
Dividend yield is just one component of total return. A share yielding 2% that appreciates 10% per year produces a better total return than a share yielding 8% that falls 5% per year. For long-term investors, dividend reinvestment (DRIP) compounds the income component significantly:
£10,000 invested at 4% yield + 4% price growth, reinvested:
Year 10: ~£21,600 (total return ~116%)
Year 20: ~£46,600 (total return ~366%)
Same without reinvesting dividends:
Year 20: ~£31,900 in shares + ~£8,000 in cash dividends
Reinvestment advantage: ~£6,700 over 20 years
