🔍 What Is Maintenance Margin?

The maintenance margin is the minimum percentage of equity you must maintain in your margin account after buying securities with borrowed money.

If the value of your securities falls below this threshold, your broker may issue a margin call, requiring you to deposit more funds or sell some assets to meet the requirement.

For example, if your broker’s maintenance margin requirement is 25%, and your account’s equity falls below that level, you’ll need to act immediately to avoid liquidation.

⚙️ How the Maintenance Margin Calculator Works

This calculator helps you estimate the equity required to maintain your open margin positions safely. It uses a simple formula to ensure you understand how much of your own capital must stay in the account.

Formula Used: Maintenance Margin=Current Market Value×Maintenance Margin Requirement (%)\text{Maintenance Margin} = \text{Current Market Value} \times \text{Maintenance Margin Requirement (\%)}Maintenance Margin=Current Market Value×Maintenance Margin Requirement (%)

The calculator takes three main inputs:

• Total Market Value of Securities (USD): The total current value of the stocks or assets in your account.
• Maintenance Margin Requirement (%): The percentage required by your broker (commonly 25% to 30%).
• Loan Amount (USD): The borrowed funds you used to buy the securities.

It then calculates how much equity you must maintain and alerts you if your balance falls below the threshold.

💡 Practical Example

Let’s understand this with an example:

• Total Market Value: $20,000
• Loan Amount: $10,000
• Maintenance Margin Requirement: 25%

Step 1: Calculate current equity: Equity=20,000−10,000=10,000\text{Equity} = 20,000 – 10,000 = 10,000Equity=20,000−10,000=10,000

Step 2: Calculate required maintenance margin: Required Margin=20,000×0.25=5,000\text{Required Margin} = 20,000 \times 0.25 = 5,000Required Margin=20,000×0.25=5,000

Step 3: Compare equity to required margin:
Since $10,000 > $5,000, you are safe from a margin call.

But if your total market value drops to $12,000: Equity=12,000−10,000=2,000\text{Equity} = 12,000 – 10,000 = 2,000Equity=12,000−10,000=2,000

Now your equity ($2,000) is below the required maintenance margin ($3,000). You’ll get a margin call.
