What payout ratio is measuring
Dividend payout ratio measures how much of a company’s earnings are being paid out as dividends over the same period. A payout ratio of 40% means the company paid 40 cents in dividends for every 1.00 of earnings, leaving the remaining 60% as retained earnings.
This metric is widely used because it connects the dividend directly to reported profitability. Even so, it is only one signal. A payout ratio can look comfortable while cash flow is weak, or it can look high in a mature sector where distributions are intentionally larger.
