Trade planning begins before an order is placed. A trader needs to understand how much capital is required, the funds available and the cost of the position. A margin calculator can help you with this.
It estimates margin needed for a planned trade. Calculation may also include trader contribution, broker funded amount, interest and holding period for MTF trading. Looking at these numbers before ordering helps make good capital planning easier.
1. Pick the Best Calculator
First check what trade you want to make.
A margin calculator could be built into the futures and options as standard. It can show SPAN margin, exposure margin and total margin. Another use of an MTF calculator is . . . It estimates interest and funding associated with a Margin Trading Facility.
This is important because MTF trading applies to eligible equity delivery transactions while futures and options have different margin rules.
2. Fill in the Right Trade Details
The calculation is done according to entered data.
Check stock or contract name, qty, market price, segment and type of trade. A slight mistake in the input may alter the margin estimate.
Remember the stock price and number of shares in an MTF trade. Suppose a share costs ₹500 and you want to buy 100 shares. The trade value is Rs. 50,000. Then the calculator can determine your contribution and the amount that is funded by using the desired margin percentage.
3. Verify Your Required Margin
Then you need to look at how much has to come from your available capital.
For derivatives, a margin calculator may have SPAN and exposure requirements. The required contribution for MTF depends on the security and rules for the margin.
As per NSE, the eligible MTF securities are Group I equity shares and Group I Equity ETFs units. Margin requirements are also determined by the security category and prescribed risk measures.
Do not regard the output of the calculator as loose cash. Leave it at the desired location.
4. Calculate Funded Amount
With MTF the broker funds some part of the trade value.
Let’s assume a trade value of ₹50,000. If your required contribution is ₹15,000, the remaining ₹35,000 could be the funded portion depending on the broker’s terms and eligible security limits.
That matters because it costs money to fund.
5. Add The Holding Period
Interest under the MTF is calculated on the amount funded and the time for which funding is utilised.
The Bajaj Broking MTF calculator lets traders input a holding period and interest rate. Then it estimates the amount of funding, margin required, and the interest amount.
Perform the calculation for the holding period you intend to use. You can also see how the funding cost changes with different holding periods.
6. Review Interest and Other Fees
Margin is one figure to look at, but there are others, of course.
Interest may be charged on the broker funded amount for MTF positions. Other charges like broking, statutory, taxes and depository charges may also be charged as per transaction and broker terms.
A simple formula for the interest funding is:
Interest = Amount Funded x Interest Rate x Number of Days/365
This gives an estimate of the interest part. The broker’s pricing structure will determine the final costs.
7. Verify Margin Risk
The margin requirements may change as the position value changes.
In MTF, the traders have to meet the margin requirements. Market movement can cause a shortfall in margins. If you lack the margin required, broker terms may permit action on the position.
Therefore, review the margin requirement and the Capital in the account.
8. Compare the calculation with your trading plan
Before you order, look at four figures:
- Total value of trade
- Required margin or contribution
- Total from broker
- Interest & Charges (Estimate)
Then compare these with your trading capital available and your intended holding period.
The calculator has to back the trade plan. It doesn’t tell you whether the trade will be profitable or result in a loss.
