A dividend is cash a company pays to its shareholders out of its profits, expressed per share. If SBI declares a dividend of ₹13.70 per share and you hold 100 shares, you receive ₹1,370 in your bank account. Companies are not required to pay dividends; many growth companies reinvest everything, while mature companies often pay regularly. Key dates matter: you must own the shares before the ex-dividend date to receive it, and on that date the share price usually drops by roughly the dividend amount, since that cash leaves the company. Dividends are taxed as income at your slab rate, and TDS may be deducted above a threshold. Dividend yield is dividend divided by price. A high yield can signal a stable payer or a company whose price has collapsed, so look at why. Dividends are one part of returns, not a reason alone to buy.
