What is a margin Calculator?
Margin trading lets you take a larger position than your available funds would normally allow, by putting down only a fraction of the trade value upfront — the broker effectively funds the rest for the day. This is common for intraday equity trades, where brokers commonly offer 4x–5x leverage (sometimes more), though the exact multiple is set by the broker and can change based on the stock and market conditions.
Enter the stock price, quantity, and the leverage your broker offers to see the margin required, and how much quantity your available funds could support at that leverage.
How margin is calculated
This is a simplified view for equity intraday trades with flat leverage. F&O margin requirements (SPAN + exposure margin) are set by the exchange per contract and aren’t a simple multiple — this calculator doesn’t model those.
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?
Your broker may issue a margin call or square off your position automatically if losses erode your margin below the required maintenance level — leverage magnifies losses exactly as much as it magnifies gains.
Is the leverage multiple the same for every stock?
No — brokers typically offer lower leverage (or none) on illiquid or highly volatile stocks, and this can change without much notice, so always confirm the current leverage for a specific stock on your broker’s app before placing the trade.
