How the dividend cluster fits together

Dividend yield answers how much annual cash distribution a share currently represents relative to price. Payout ratio and cash-flow coverage help test whether that distribution appears supportable. Dividend growth measures the pace at which distributions have changed, while reinvestment models show how additional shares can compound future income under a set of assumptions.

None of those measures is useful in isolation. A high yield can be created by a falling share price, a long dividend-growth record does not guarantee future increases, and a reinvestment projection is only as realistic as the assumptions entered.
