A margin call occurs when your equity falls below the maintenance margin requirement. You will need to deposit additional funds or sell securities to meet the margin requirement. This calculator assumes a simple margin structure; actual margin requirements may vary by broker and security type. Not financial advice.

How It Works
This calculator helps you determine the stock price at which your brokerage will issue a margin call, forcing you to deposit more funds or sell assets. Understanding this threshold is crucial for managing risk in your leveraged investments, especially with potential market volatility anticipated in 2026.
The margin call price is calculated using the formula: Loan Amount / (Number of Shares * (1 - Maintenance Margin Percentage)). We determine your current margin and cushion by comparing your equity to the total market value and the maintenance margin requirement.
A common mistake is forgetting to account for commissions or other trading fees, which can subtly reduce your equity. Always be aware of your specific brokerage's maintenance margin requirements, as these can vary and impact your margin call trigger.
Example: Tech Stock Investment
- 1 Imagine you purchased 1,000 shares of 'Quantum Innovations Inc.' (QII) at $50 per share, for a total of $50,000. Your brokerage has an initial margin requirement of 50% and a maintenance margin of 30%. You borrowed $25,000.
- 2 Using the formula, your margin call price would be $25,000 (Loan Amount) / (1,000 shares * (1 - 0.30 maintenance margin)) = $35.71. If QII's price drops to $35.71, your equity would be $10,710, which is exactly 30% of the $35,710 market value, triggering a margin call.
- 3 In this scenario, if QII's stock price falls to $35.71, you will receive a margin call. Your current margin is the percentage of your equity relative to the market value, and your cushion is the dollar amount your equity exceeds the maintenance margin requirement.
- 4 To avoid a margin call, you would need to deposit additional funds to bring your equity above the maintenance margin, or sell some of your QII shares. Monitoring your margin cushion allows you to proactively manage your risk before a margin call is issued.
