Margin trading (also called Margin Trading Facility, or MTF) is a way to buy more stocks than you could afford with just your own cash. Essentially, your broker lends you money to complete a trade. You pay only a fraction of the total cost upfront (this is called the “margin”), and the broker funds the rest. Over time, you pay interest on what you borrow.
This might sound risky, but it gives you more buying power. For example, if you spot a stock you believe will rise and don’t have enough funds, margin trading lets you grab that opportunity without waiting to save up the entire amount.
How Does Margin Trading Actually Work?
1. You put in your margin
To begin, you deposit a margin amount — this could be in cash or by pledging the shares you already own. Some brokers let you use your existing stocks (or ETFs) as collateral instead of cash.
2. Broker lends the rest
Once your margin is in, your broker funds the remaining amount needed for the trade. Suppose you want to buy ₹4,00,000 worth of a stock but only have ₹1,00,000 — with margin trading, the broker might give you the extra ₹3,00,000.
3. You pay interest
Yes — interest is charged on the part of money borrowed. For example:
With Kotak Securities, you can get up to 5× leverage on 1,300+ stocks, and they charge around 9.69% p.a. under certain plans. Kotak Securities
On Groww, the interest might be about 14.95% p.a. or 0.041% per day (this varies).
4. Holding period
Depending on the broker, you may hold the leveraged position for a longer duration. For Kotak Securities, there’s no fixed time limit — you can “hold your position as long as you wish.”
What Are the Benefits of Margin Trading?
Bigger bite from a small budget: Because you only need partial money upfront, you can buy more shares than usual. This gives you leverage to potentially amplify profits.
Use your existing investments: Rather than keeping money idle, you can pledge shares as margin to generate more buying power.
Flexible holding: Depending on broker, there may be no strict time limit. As with Kotak, you can “buy now, pay later” and hold your positions.
Research help: Brokers like Kotak Securities provide research-backed stock picks specifically for MTF users, which can guide your margin-funded trades.
The Risks You Need to Watch Out For
Leverage cuts both ways: While margin can magnify gains, it also magnifies losses. If share prices fall, your loss will be larger compared to investing only your own money.
Interest costs eat into profit: The longer you hold a margin trade, the more interest you pay — this can significantly reduce your returns if not managed.
Margin shortfall or call: If the value of your pledged shares drops or your margin position weakens, the broker may ask for more money (or sell part of your holding) to cover the shortfall.
Complexity for beginners: Margin trading isn't just “free extra money” — understanding how interest, pledging, and conversion to delivery works is important. Without that, you may land in a risky spot.
Is Margin Trading Right for You?
Margin trading appeals mostly to active or experienced investors who:
- Have a reasonable understanding of risk
- Are confident about short- or medium-term price movements
- Can afford to keep a buffer for interest payments or potential margin calls
If you’re just starting out, it’s good to be cautious. Use the margin facility only when you clearly understand how much you’re borrowing, how interest will build up, and what will happen if the market moves against you.
Final Thoughts
Margin trading (MTF) can be a powerful tool in your investing toolbox. It allows you to enhance your buying capacity and potentially scale your gains — but it's not free leverage. Every broker has its own terms, interest rates, and rules about how you pledge and convert shares.
If you’re considering using MTF, do your homework: calculate how much interest will cost you, understand how much time you’re comfortable holding a leveraged position, and keep a close eye on your trades. When used judiciously, margin trading can open up opportunities that would otherwise be beyond your immediate reach. But if used recklessly, it can amplify risk. So, treat it like a tool — and use it smartly.
