The Equity Margin Calculator is a simple, intuitive tool that calculates the margin required for your positions based on account equity, leverage, and position size. With just a few inputs, you can instantly know how much capital is tied up, your free margin, and whether your trade meets risk management requirements.

Whether you’re a professional trader, beginner, or risk-conscious investor, this calculator helps you trade smarter, safer, and more profitably.

💡 What Is Equity Margin?

Equity margin refers to the portion of your account equity used to open and maintain leveraged trading positions.

It is calculated based on:

Account equity: Total capital in your trading account.
Position size: The total value of the trade you want to enter.
Leverage applied: The multiplier that amplifies your position.

Equity margin ensures that your account has sufficient funds to cover potential losses. If your equity drops below the required margin, brokers may issue a margin call or liquidate your positions.

🧮 Formula for Equity Margin Calculation

The equity margin calculation generally uses the following formula: Liquidation Price=Entry Price×[1−(1Leverage)+(Maintenance Margin Rate+Account EquityPosition Size)]\text{Liquidation Price} = \text{Entry Price} \times \left[1 – \left(\frac{1}{\text{Leverage}}\right) + \left(\text{Maintenance Margin Rate} + \frac{\text{Account Equity}}{\text{Position Size}}\right) \right]Liquidation Price=Entry Price×[1−(Leverage1)+(Maintenance Margin Rate+Position SizeAccount Equity)]

Where:

Entry Price = price at which the position is opened
Leverage = borrowed funds multiplier
Maintenance Margin Rate = broker-defined requirement
Account Equity / Position Size = available capital proportion

This formula helps determine the price at which your position would be liquidated if the market moves against you.

📊 Example: Equity Margin Calculation for Stock Trading

Suppose you want to trade $10,000 worth of a stock with your account equity of $1,500, leverage of 10x, and a maintenance margin rate of 0.5% (0.005).

Step 1: Input Values

Account Equity = $1,500
Position Size = $10,000
Entry Price = $100
Maintenance Margin Rate = 0.005
Leverage = 10x

Step 2: Calculation Using Formula Liquidation Price=100×[1−110+(0.005+150010000)]\text{Liquidation Price} = 100 \times \left[1 – \frac{1}{10} + \left(0.005 + \frac{1500}{10000}\right)\right]Liquidation Price=100×[1−101+(0.005+100001500)] =100×[0.9+(0.005+0.15)]=100×1.055=105.50= 100 \times \left[0.9 + (0.005 + 0.15)\right] = 100 \times 1.055 = 105.50=100×[0.9+(0.005+0.15)]=100×1.055=105.50

✅ Liquidation Price = $105.50

This means if the stock price moves to $105.50 in the opposite direction of your leveraged position, your broker may automatically liquidate it to prevent further losses.
