How to calculate margin call

Margin trading has become increasingly popular among investors looking to amplify their gains in the financial markets. However, it also comes with higher risks, with margin calls being one of them. In this article, we’ll guide you through understanding and calculating margin call, so you can manage your investments more effectively.
What is a Margin Call?
A margin call occurs when the value of an investor’s margin account falls below the broker’s maintenance margin requirement. It requires the investor to either add more funds to their account or sell off some assets to meet the minimum balance requirements. If this doesn’t happen, the broker has the right to sell assets without any prior notice.
Understanding Key Terms
Before calculating a margin call, let’s go over several key terms that are crucial to understanding how it works:
1. Initial Margin Requirement (IMR): The amount you have to deposit as collateral when you open a new position on margin.
2. Maintenance Margin Requirement (MMR): The minimum percentage of equity that must be maintained in your margin account.
3. Margin Equity: The total value of your investment plus borrowed funds.
4. Margin Maintenance Level: The minimum equity-to-margin ratio required in your account.
Steps to Calculate Margin Call
Now that you understand these basic terms, calculating a margin call follows these steps:
1. Determine your Initial Margin Requirement (IMR)
IMR varies from broker to broker but is generally around 50% of the total investment value.
2. Calculate your Maintenance Margin Requirement (MMR)
Maintenance margins often range between 25% and 40%, but this depends on your broker and the asset(s) invested in.
3. Assess your position’s current market value
Add up the current market value of all securities in your margin account.
4. Find your account’s total equity
Total Equity = Your Contribution + Borrowed Funds
5. Calculate the Margin Maintenance Level
Margin Maintenance Level = (Total Equity / Current Market Value) * 100
6. Compare the Margin Maintenance Level to MMR
If your Margin Maintenance Level falls below the MMR, you will receive a margin call.
Example
Let’s go through an example to understand the margin call calculation better:
1. Initial investment: 10,000
2. Borrowed funds: 10,000
3. Total investment: 20,000
4. Current market value: 16,000
5. Initial Margin Requirement (IMR): 50%
6. Maintenance Margin Requirement (MMR): 30%
First, calculate your total equity:
Total Equity = Your Contribution + Borrowed Funds
Total Equity = 10,000 + (-2,000) [Market value dropped by 4,000]
Total Equity = 8,000
Next, calculate the Margin Maintenance Level:
Margin Maintenance Level = (Total Equity / Current Market Value) * 100
Margin Maintenance Level = (8,000 / 16,000) * 100
Margin Maintenance Level = 50%
Since our Margin Maintenance Level is higher than the MMR of 30%, there is no margin call in this instance.
Conclusion
Understanding and calculating margin calls in advance can help you manage your investments more efficiently and avoid unexpected liquidation of your positions. Be sure to keep an eye on your account’s maintenance margin level and stay ahead of potential risks. Remember that while trading on margin might increase your potential returns, it also exposes you to higher risks; always invest responsibly and maintain a well-diversified portfolio.
