Margin Calculator

About the Margin Calculator

A margin calculator tells you exactly how much capital you need to set aside to open a leveraged trading position, based on your position size, leverage, and the asset's price. Instead of guessing whether you have enough free margin for a trade, enter your numbers and see the required margin instantly.

Why This Tool Exists

Getting caught with insufficient margin mid-trade, or worse, hitting a margin call, is a frustrating and avoidable problem. This tool exists so you know exactly how much of your account balance a trade will tie up before you actually place it.

How to Use It

1. Step 1. Enter your intended position size.
2. Step 2. Enter the leverage ratio you're using.
3. Step 3. Enter the current asset price, if required for the calculation.
4. Step 4. Click Calculate to see your required margin.

Key Features & Benefits

• Shows required margin instantly from position size and leverage
• Helps prevent overcommitting account balance to a single trade
• Useful for planning multiple simultaneous positions
• Simple inputs matched to what brokers and exchanges display
• Free, fast, and broker-agnostic

How It Works

Required margin is calculated as Position Size ÷ Leverage. So a $50,000 position at 50x leverage requires just $1,000 in margin, while the same position at 10x leverage would require $5,000. Understanding this relationship helps you plan how many trades you can realistically run at once without stretching your account balance too thin across multiple open positions.
