Leverage & Margin Quick Reference

For a simple position where the notional value is known, the approximate margin percentage is the reciprocal of leverage.

1:10 10% approximate margin
1:20 5% approximate margin
1:50 2% approximate margin
1:100 1% approximate margin

What Is Trading Margin?

Trading margin is the amount of funds a broker requires as collateral when a trader opens a leveraged position. Margin allows traders to control a position whose total market value is larger than the amount of capital committed as margin.

Margin should not be confused with a trading fee or a maximum possible loss. The margin requirement is related to the size of the position and the leverage available on the account.

Basic Margin Formula

A simplified margin calculation can be represented as:

Required Margin = Notional Position Value ÷ Leverage

The approximate margin percentage can also be expressed as:

Margin Percentage = 1 ÷ Leverage × 100

Example: 1:100 Leverage

Suppose a position has a notional value of $100,000 and the applicable leverage is 1:100.

$100,000 ÷ 100 = $1,000 estimated margin

This is a simplified example. Actual broker margin requirements may differ depending on the instrument, account currency, contract specifications, regulatory requirements and broker policies.

Margin vs. Leverage

Leverage determines how much market exposure can be controlled relative to the required margin. When leverage increases, the theoretical margin percentage required for the same notional position decreases.

However, higher leverage does not automatically make a trade less risky. A larger position can still generate large gains or losses from relatively small market movements.

What Can Affect Required Margin?

  • Position size
  • Contract size
  • Current market price
  • Account leverage
  • Instrument specifications
  • Account currency
  • Currency conversion rates
  • Broker margin policies
  • Tiered or dynamic margin requirements
  • Applicable regulatory restrictions

What Is Free Margin?

Free margin generally refers to the portion of available account equity that is not currently being used as required margin for open positions. It can be affected by open trade profits and losses, existing margin requirements and account equity.

What Is a Margin Call?

A margin call can occur when account equity falls to a level where the broker's margin requirements are no longer adequately covered. Brokers may have specific margin-call and stop-out rules.

Traders should always check their broker's current margin, liquidation and stop-out policies rather than relying solely on a calculator estimate.

Example Margin Requirements

The examples below assume a $100,000 notional position and a simple fixed-leverage calculation.

Leverage Approx. Margin % Approx. Margin on $100,000
1:10 10% $10,000
1:20 5% $5,000
1:50 2% $2,000
1:100 1% $1,000
1:200 0.5% $500
1:500 0.2% $200

Margin Calculator FAQ

What is trading margin?
Trading margin is the amount of funds a broker requires as collateral to support a leveraged position.
How is forex margin calculated?
A simplified calculation divides the notional position value by the applicable leverage. The exact calculation can vary according to the broker and instrument.
Does higher leverage mean lower margin?
For the same notional position under a simple fixed-leverage model, higher leverage generally results in a lower theoretical margin requirement.
Is margin the same as my potential loss?
No. Margin is collateral used to support a leveraged position. Potential trading loss depends on the position size and the market's price movement.
Can I use this calculator for gold and cryptocurrencies?
The calculator can be used as a simplified estimate when the correct contract size, price and applicable leverage are known. However, gold, cryptocurrencies, indices and other instruments can have different margin rules. Always verify the broker's specifications.
Can my broker require more margin than this calculator shows?
Yes. Brokers can apply instrument-specific, account-specific or tiered margin requirements. Regulatory restrictions and market conditions can also affect the applicable requirement.
Does margin protect me from losing more money?
No. Margin is not a maximum-loss limit. A leveraged position can lose substantially more than the initial margin requirement. Traders should understand their broker's risk controls and liquidation policies.
