# Understanding all about Futures and Options margin calculation What is the margin payable on one lot of futures? Frankly, it will depend on a lot of factors. For example, whether the contract is for near month, mid-month or far month will make an impact. Secondly, the margins will also depend on whether the stock in question is volatile or flat. A volatile stock will attract more margins. Thirdly, margins are also impacted by whether the trade is normal trade, intraday (MIS) trade or cover order. Let us simulate different situations and see the impact of margin simulation in all these situations. Let us also understand how to calculate initial margins for futures and types of margins in future contract with distinct futures margin examples. Here is how to go about it.

In the above case, the Normal Margin is a combination of VAR margin and the Extreme Loss Margins (ELM). The ELM margin is also known as the exposure margin. IN the past, only the VAR margin was mandatory but now SEBI has made it mandatory to collect the VAR and ELM margins as part of the normal margins. However, if you want to pay lower margins, then you can opt for an intraday trade. This intraday has to strictly closed intraday and if the trader does not close the trade then the broker RMS will close the trade automatically around 3.15 pm. If you want still more leverage, then you can opt for Cover Order. In a cover order, you put the stop loss as part of the order and in that case since your risk is limited still further, you get higher leverage. In the above instance, the trader can move from buying just 6 lots in normal order to buying 21 lots in the intraday order and right up to 62 lots in case of cover order. Of course, while the Normal margins are fixed by the exchange, the amount of leverage to be given on intraday orders and on cover orders is something the broker has the discretion to decide.
