Dividend Yield Explained: What It Means and What It Hides
Updated: 2026-11-08
Dividend yield is the first number most people look at when choosing income shares. It is useful, but on its own it can mislead. Here is what it measures and what to check next to it.
How it is calculated
A share at 50 that pays 2 a year yields 4 %. If the price falls to 40 and the dividend stays at 2, the yield rises to 5 %. That is the catch: the yield goes up when the price goes down, often because investors expect trouble.
Yield on cost
Yield on cost compares today's dividend with the price you paid. Buy at 50 with a 2 dividend (4 %), and if the dividend grows to 4 over the years your yield on cost is 8 %, even though new buyers may only get 3 or 4 % at the higher price.
Check these too
- Payout ratio: dividends ÷ profit. Above about 80 % for most companies, there is little room to keep paying if profits dip.
- Dividend history: has it been paid, and raised, through recessions?
- Debt and cash flow: a dividend paid with borrowed money cannot last.
- Taxes: many countries tax dividends at source; foreign dividends can be taxed twice unless a treaty applies.
Why very high yields are a warning
When a yield is far above the market average, the market often expects the dividend to be cut. A 10 % yield that is halved leaves you with a 5 % yield and, usually, a lower share price as well. A steady 3 % that grows each year often pays more over time.
Example
Two shares cost 100. A yields 8 % and B yields 3 %, but B raises its dividend 8 % a year. After 13 years B pays about 8 a year on your original 100, and it keeps growing. If A had to cut its payout in a downturn, B would be ahead much sooner. Model it in the dividend calculator.
