What Is the Zerodha Margin Calculator?
The Zerodha Margin Calculator is an estimation tool that helps traders understand how much capital may be required before placing a trade. It calculates the total trade value, estimated margin requirement, implied leverage and remaining funds.
You can use it for equity intraday, equity delivery, futures and options calculations. Since actual margin requirements may change throughout the trading day, this calculator allows you to enter the current margin value yourself rather than relying on a fixed rate.
Check whether your available balance may be sufficient for the planned position.
Change the price, quantity or margin percentage to compare multiple trade scenarios.
See how much of your available capital the estimated margin could consume.

Understanding Common Trading Modes
The margin structure depends on the selected product, instrument and current exchange requirements.
| Trading Mode | Typical Purpose | Calculator Input | Important Note |
|---|---|---|---|
| Equity Intraday | Positions opened and closed on the same trading day | Price, quantity and current margin percentage | Leverage can differ by stock and broker policy |
| Equity Delivery | Shares held beyond the trading day | Price, quantity and normally the full trade value | Delivery commonly requires the complete purchase amount |
| Futures | Trading standardised derivative contracts | SPAN margin plus exposure margin | Requirements change with volatility and exchange updates |
| Option Buying | Purchasing call or put option contracts | Option premium multiplied by lot quantity | The buyer generally pays the applicable premium |
| Option Selling | Writing call or put option contracts | SPAN, exposure and any additional applicable margin | Margin can be significantly higher than option buying |
