What is a Margin Calculator?
This calculator is a leverage-sizing illustration: enter a leverage multiple that your broker currently shows for an eligible equity trade to see the implied trade value and funds required. It is not an exchange/SEBI regulatory-margin engine and does not calculate stock-specific VaR, ELM, MTM, delivery or special margins.
NSE's current margin FAQ states that trading members in the capital-market segment must collect at least 20% upfront margin in lieu of VaR and ELM, while other margins can also apply. Margin Trading Facility (MTF) has its own VaR/ELM-based framework. Therefore a simple 4x or 5x multiple is only a sizing shorthand and may not be available for a particular stock or trade. Always use the live margin shown by your broker/exchange system before placing an order.
How margin is calculated
This converts an assumed leverage multiple into a position-size illustration. It is not the regulatory margin requirement for a security. Actual cash-market and MTF requirements can depend on VaR/ELM and other margins; F&O uses its own exchange margin framework.
Worked example: how leverage changes what ₹50,000 can buy
With ₹50,000 available and a ₹500 stock, no leverage (1x) buys 100 shares — a ₹50,000 position. At an illustrative 2x multiple it corresponds to 200 shares (₹1,00,000 exposure); at 4x, 400 shares (₹2,00,000 exposure); and at 5x, 500 shares (₹2,50,000 exposure). These are arithmetic illustrations, not a statement that the exchange or your broker will permit those multiples for the selected stock.
Leverage scales both potential profit and potential loss. A 2% adverse move on an illustrative ₹2,50,000 position is ₹5,000 before charges — 10% of the original ₹50,000 funds. Actual margin calls and square-off rules depend on the applicable regulatory, exchange and broker framework.
Why leverage changes risk faster than it changes the arithmetic
A leverage multiple does not improve the probability that a trade will be profitable. It increases the exposure controlled by the same amount of funds, so both gains and losses are magnified relative to the capital committed. Regulatory and broker margin requirements can also change as risk parameters change. Use this page to understand position-size arithmetic only; it is not a recommendation to use leverage or to use the maximum multiple shown by a broker.
Frequently asked questions
Does this apply to F&O trading?
No — F&O margins are computed by the exchange using SPAN and exposure margin methodology, which varies by contract and market volatility, not a flat leverage multiple. This calculator is for equity intraday trades only.
What happens if a leveraged position moves against me?
Additional margin can become payable and the broker may have rights to square off positions under the applicable agreement and exchange/broker rules. Leverage magnifies losses as well as gains, so verify the live margin and risk policy before trading.
Is the leverage multiple the same for every stock?
No. Actual margin can depend on the security, VaR/ELM and other applicable margins as well as broker risk controls. Confirm the live requirement for the specific security and segment before placing the trade.
What’s the difference between margin and exposure?
Margin is the funds you must have available to enter and hold a leveraged position. Exposure is the total value of the position you control — in a 5x leveraged trade, your margin is one-fifth of your exposure.
Do I pay interest on the leveraged (borrowed) portion?
Funding charges depend on the product and broker terms. Margin Trading Facility and other funded positions can carry explicit funding costs; do not infer the cost from the leverage multiple. Check the broker tariff and agreement for the product you are using.
Can leverage on a stock change during market hours?
The live margin or broker risk limit can change when applicable risk parameters or broker controls change. Do not rely on a multiple observed earlier; check the current order-screen margin before each leveraged trade.
Does this calculator recommend using the maximum available leverage?
No. It only illustrates the arithmetic of a leverage multiple. Maximum available leverage can leave less buffer for adverse price moves and margin changes; the appropriate risk level is a separate decision and this calculator does not provide trading advice.
