Dividend yield

Dividend per share divided by share price. A ₹18 dividend on a ₹1,200 share yields 1.5%.

In India the trap is that companies often declare dividends as a percentage of face value, and price doesn't enter the figure. So a 900% dividend on a ₹2 face value share is ₹18, and the yield is 1.5%, not 900%.

A high yield is ambiguous. It can mean a mature business returning cash, and it can mean a price that has fallen because the market expects the dividend to be cut. Check the payout ratio and the cash flow to tell which.

For an Indian investor the tax treatment changes what the yield is worth. Dividends are taxed in your hands at your slab rate, so a 3% gross yield is meaningfully less after tax if you're in the highest bracket, and a buyback returning the same cash can be worth more depending on the rules in force.

Convert to rupees per share first, always. A percentage on face value isn't a yield.
