How much money do you need to start trading stocks in India?

There is no legal minimum. You can open a demat account and buy a single share. The real question is how small an account can be and still trade a plan properly, and that depends on charges and position size.

Charges weigh most on small trades

Most delivery charges grow with the trade: STT is 0.1% of the buy and 0.1% of the sell, and stamp duty, exchange and SEBI fees are small percentages too. One charge does not grow. The DP charge, ₹15.34 at Zerodha each time you sell a stock, is the same on ₹5,000 as on ₹5 lakh.

Here is what a delivery round trip costs at Zerodha, buying and selling at the same price:

A ₹5,000 trade has to rise more than half a percent just to break even. The charges calculator works this out for any delivery, intraday or margin trade.

Risk per trade sets your position sizes

Many traders risk a small, fixed share of the account on each trade, often between 0.25% and 1%. That share, and the distance to your stop, decide how big each position can be (the position sizing guide shows the formula).

Take a stock at ₹200 with a stop at ₹184, 8% below, and 1% risk per trade:

On the ₹50,000 account, every trade starts about 0.06R behind before the price moves, twice the drag of the larger accounts. On a strategy that earns 0.2R a trade, that is almost a third of the profit.

Small accounts are tempted to cheat on size

The bigger danger for a small account is the temptation to risk 5% or 10% a trade so the rupee gains feel worth the effort. At 5% a trade, ten losses in a row take 40% of the account, which then needs a 67% gain to recover (the drawdown tables have the full list). Losing streaks of that length are ordinary for many strategies.

A sensible way to think about it

Start with an amount you could lose without it changing your life, because the first year of trading often costs money. Size every trade from its stop at a risk you could sustain through twenty losses. If the positions that leaves you are so small that charges eat the edge, the honest answer is to trade less often, or to keep practising on paper while the account grows from savings, not from bigger bets.
