Margin Calculator
About the Margin Calculator
Margin is the upfront capital you need to take a leveraged position — buying or selling more than your cash alone would allow. With leverage, a fraction of the trade's value funds the whole position, magnifying both gains and losses.
Enter the price, quantity and leverage, and this calculator shows the margin required to take the position.
Frequently asked questions
How is margin calculated?
Margin = (price × quantity) ÷ leverage. At 5× leverage, a ₹5,00,000 position needs ₹1,00,000 of margin; the broker funds the rest. Higher leverage means less margin but more risk.
What is leverage?
Leverage lets you control a position larger than your capital. 5× leverage means ₹1 of margin supports ₹5 of position. It multiplies returns on the margin — and losses just as much.
Why is margin trading risky?
Because losses are calculated on the full position, not just your margin. A small adverse move can wipe out your margin and trigger a margin call for more funds, or a forced square-off of your position.
What is a margin call?
A demand from your broker to add funds when losses erode your margin below the required level. If you do not top up, the broker may close your position automatically to limit further loss.
How much leverage do brokers allow?
It varies by segment and by regulation — intraday equity, F&O and commodities each have different margin rules set by SEBI and the exchanges. Available leverage has been tightened in recent years, so check your broker's current limits.
Disclaimer: This calculator is for information and education only. It is not investment advice and not a recommendation or a tip, and it does not predict prices. Trading in shares and derivatives carries a risk of loss: futures and sold options are leveraged, and a loss on them can exceed the margin paid. Brokerage differs by broker, and brokerage, taxes and exchange charges change over time. SEBI’s studies found that 93% of individual traders in equity futures and options made losses between FY22 and FY24, and 87.7% did in FY26. Every figure is computed solely by applying the formula and assumptions stated on this page to the inputs you entered.
