What is margin in trading, and how can you take a position worth ₹25,000 without paying ₹25,000? In the last lesson, What Is Slippage in Trading?, you learned about the price you actually get. Now we look at the money you pay it with. Margin is one of the most useful ideas in trading, and also the one that has hurt the most beginners, so we will go slowly and use numbers.

1. What Is Margin in Trading?
Margin is the amount of money (or collateral) your broker blocks in your trading account as security before you take a trade. It is not a fee and it is not spent. It is a deposit that is held while your position is open and released when the position is closed.
Think of renting a house. You pay a security deposit to the owner. The deposit is not the rent, and you get it back when you leave, unless you have caused damage. Margin works the same way. The exchange and your broker want to be sure you can cover your losses, so they hold some of your money against the trade.
You manage this money from your trading account. If you want to refresh how the two accounts differ, revisit What Is a Trading Account?. A general definition is also given in Investopedia’s explanation of margin.
2. Margin vs Full Payment: A Simple Example
Say a share costs ₹250 and you want 100 shares. The value of the position is ₹25,000.
- Delivery (you buy and keep the shares): you pay the full ₹25,000.
- Intraday (you buy and sell the same day): your broker may ask you to keep only a part of the value as margin. For example, if the broker’s requirement for that share is 20%, ₹5,000 is blocked and the other ₹20,000 is not needed in cash.
The 20% above is only an example. The actual margin depends on the stock, the broker and the rules at that time, and your broker’s platform shows the exact figure before you place the order. Intraday trades must be closed the same day, as explained in What Is Intraday Trading?. If you do not close, many brokers close the position automatically shortly before the market ends. The exact time is set by your broker.
Pro Tip: Always look at the “margin required” figure shown on the order window before you confirm. It tells you how much money will be blocked for that exact trade.
3. Types of Margin You Will Hear About
You will see several margin terms in your trading app:
| Type | Where it applies | In simple words |
|---|---|---|
| Delivery margin | Buying shares to hold | Practically the full amount of the purchase |
| Intraday margin | Buying and selling within the same day | A fraction of the position value, set by the broker and exchange rules |
| SPAN + Exposure margin | Futures and options | Margin set by the exchange’s clearing system based on how risky the position is |
| Margin pledge | Using your holdings as collateral | Shares you already own count towards your margin (see next section) |
Some brokers also offer MTF (Margin Trading Facility), where the broker funds a part of a delivery purchase and charges interest on the amount lent. It increases your buying power but adds interest cost and risk, so read the terms carefully before using it.
SEBI also requires brokers to collect the required margin upfront for these positions, so the very high “10x or 20x” style leverage that some traders used years ago is no longer allowed in the same way. You can read about investor rules on the SEBI Investor portal. Margin rules are revised from time to time, so confirm the latest details with your broker.
4. Margin Pledge: Using Your Shares as Margin
If you already own shares in your Demat account, you may not need to add cash to get margin. You can pledge them. In What Is a Demat Account? you learned that your shares are stored there. Pledging puts a lien (a hold) on those shares in favour of your broker, while the shares stay in your own Demat account and remain yours.
To pledge shares, you select them in your broker’s app and confirm through an authorisation sent by the depository (CDSL or NSDL), usually with an OTP.
Not the full value of the shares counts as margin. The exchange applies a haircut, a percentage reduction to allow for price changes:
- Shares worth ₹1,00,000
- Haircut 20% (example)
- Margin you receive = ₹1,00,000 − ₹20,000 = ₹80,000
Stable large companies usually have a smaller haircut than volatile ones. The actual haircut for each share is published and can change. You also keep corporate benefits such as dividends on pledged shares, but you must clear margin dues before you can unpledge them.
5. What Happens If Your Margin Falls Short
When a trade goes against you, the loss is deducted from your available funds. If the available money drops below what the position needs, you have a margin shortfall. Usually this leads to:
- A warning from your broker.
- A chance to add funds or close some positions yourself.
- If you do nothing, the broker may square off (close) your positions without asking you. The loss is then fixed.
Brokers can also charge a penalty for a shortfall under the exchange rules. This is why you should never use every rupee of your available margin. Keep a buffer.
6. Why Margin Is Powerful and Risky
Margin lets you control a bigger position than your cash alone allows. That works in both directions.
Using our example (100 shares at ₹250, ₹5,000 margin blocked):
- If the price rises by ₹5 (2%), you earn ₹500. That is 10% of the ₹5,000 margin.
- If the price falls by ₹5 (2%), you lose ₹500. That is also 10% of the margin.
A 2% move in the share became a 10% move in your money. A bigger fall hurts much more. And remember that brokerage, taxes and slippage, which we covered in the brokerage lesson and the previous lesson, are paid on the full position value, not just on the margin.
In some derivative trades, the loss can even be larger than the margin blocked. That is why we will treat risk management as a full category later. Until then, remember: margin is borrowed buying power, not extra money.
7. Common Beginner Mistakes
- Thinking margin is profit or free money. It is a deposit that protects the broker and exchange.
- Using the maximum margin available. One bad trade can then end your day or your account.
- Ignoring the margin required figure before placing an order.
- Forgetting to square off intraday positions, then being closed out at a price you did not choose.
- Treating pledged shares as untouchable. If losses grow, the broker can sell them.
- Forgetting the haircut, then being surprised by a smaller margin limit.
8. Key Points to Remember
- Margin is a deposit blocked against your trade, not a cost.
- Delivery needs the full amount. Intraday and F&O need a fraction.
- Pledged shares can give you margin, but a haircut reduces their value.
- A shortfall can lead to forced closure of your positions.
- Margin magnifies both profit and loss. Keep a buffer and trade small.
9. Frequently Asked Questions
Is margin a fee that I lose?
No. Margin is blocked while your position is open and released when you close it. You lose it only to the extent your trade loses money.
Can I trade without any margin?
Delivery purchases need the full payment, and derivatives need margin. Every position needs money or collateral behind it.
What is the difference between margin and brokerage?
Brokerage is a fee you pay your broker for each order. Margin is a deposit held against your position. Brokerage is spent, margin is returned.
Why does margin change from stock to stock?
Riskier or more volatile stocks need higher margin, because the chance of a big loss is bigger. The exchange and broker set the requirement.
What is a margin call?
It is a demand to add funds when your margin falls short of the requirement. In many Indian brokers this appears as an alert or a forced square-off rather than a phone call.
Can I lose more than the margin I put in?
In some trades, yes, especially certain derivative positions where the loss can exceed the margin blocked. This is why position size matters so much.
Do pledged shares still earn dividends?
Yes, the shares remain yours, so benefits like dividends continue.
Should a beginner use margin?
Margin is not necessary to learn. Many beginners are safer starting with small delivery trades or very small intraday sizes while they learn how losses feel.
