Every forex trader needs to understand how to calculate margin, free margin and margin level in forex trading.

Understanding these fundamental principles helps traders manage risk effectively and avoid forced liquidation from a lack of sufficient margin.

We will explore the fundamental aspects of margin usage in forex trading. By learning to use and manage margin, you can create more effective forex strategies and increase your profit margin.

Basic Margin Formula in Forex Trading

To calculate forex margin correctly traders must first understand the basic margin formula. Margin describes the necessary capital that traders need to start and uphold a forex trading position.

Brokers set minimum margin requirements as a method to reduce trading risk. Making a correct margin calculation also helps traders in their risk management processes.

The basic formula for calculating margin is:

Margin = Position Size x Pip Value

Let's break this down:

  • The Position Size represents how many units or lots of a currency pair you have in your trade. A standard lot represents 100,000 units of base currency.
  • The pip value represents the monetary worth of one pip point which depends on both the size of your position and the specific currency pair you are trading. A pip represents the smallest price movement possible in the quote currency. The pip value results from dividing the position size by the pip distance of the currency pair. With a standard lot of EUR/USD having 100,000 units and a pip distance of 0.0001 the pip value amounts to:

A position of 100,000 units divided by the pip distance of 0.0001 equals a pip value of $10.

The minimum margin requirement for a 1 standard lot long position in EUR/USD amounts to:

Calculating margin for one lot results in $100 when pip value is $10 for each lot.

Several adjustments exist from this basic principle which depend on factors such as leverage. Let's explore some advanced margin calculations.

How to Calculate Used Margin in Forex Trading?

Used margin represents the portion of your account equity that serves as collateral for your existing open trades. The calculation of used margin requires multiplying the size of each open position by the current market price.

For example, say you have:

  • The trader holds one standard lot long position in EUR/USD at the trading price of 1.1200.
  • The trading account holds a short position of 0.5 lots in GBP/USD at the exchange rate of 1.2500

To calculate the used margin:

EUR/USD Position:

  • Position Size: 1 Lot
  • Current Price: 1.1200
  • Position Value: 1.1200 x 100,000 units = $112,000

GBP/USD Position:

  • Position Size: 0.5 Lots
  • Current Price: 1.2500
  • Position Value: 1.2500 x 50,000 units = $62,500
  • Total Used Margin = $112,000 + $62,500 = $174,500

This figure indicates the portion of your account equity that serves as collateral to maintain your open trading positions.

What is Free Margin in Forex Trading and How to Calculate It?

After we understand how much margin we have used we can determine our free margin. Free margin represents the funds in your forex trading account that you can use to open new trades or support existing trades against market movements.

The free margin amount equals the total equity balance when you remove the used margin from it.

Free Margin = Total Equity - Used Margin

For example, if your account has:

Total Equity: $200,000

Used Margin (from above): $174,500

Free Margin = Total Equity - Used Margin

= $200,000 - $174,500

= $25,500

The trader possesses $25,500 of available free margin to invest in new positions or sustain existing accounts through market changes prior to receiving a margin call or liquidation order.

What Is a Good Margin Level in the Forex Trading Market?

Now that we can calculate free margin, the next question is: what is considered a "good" margin level in the forex trading market?

The margin level represents the percentage of your account equity that is currently utilized for margin purposes. It is calculated as:

Margin Level represents the percentage of Total Equity that has been allocated as Used Margin which is calculated by dividing Used Margin by Total Equity and then multiplying the result by 100.

A margin level below 50% represents a healthy account status whereas exceeding 80-90% becomes risky due to limited capacity to absorb negative market movements before encountering margin calls or liquidation.

Using the example numbers above:

  • Used Margin: $174,500
  • Total Equity: $200,000

The Margin Level percentage is obtained by dividing Used Margin by Total Equity and multiplying the result by 100.

= ($174,500 / $200,000) x 100

= 87.25%

This trader faces increased risk because their margin level is above 80% and should decrease their position sizes to reduce margin usage and maintain strong capitalization.

Margin calculation may vary depending on each currency and is not required for every trader. For example, it is recommended that traders who want to trade with major currency pairs in the forex market make margin calculations to avoid possible risks and losses.

Most Common Margin Calculation Mistakes in Forex Trading

Margin calculations appear simple but traders frequently make several typical mistakes while determining them.

Here are the most common margin calculation mistakes made by traders:

  • Forgetting Leverage: Leverage expands the necessary margin requirements so that with 1:100 leverage you only need to deposit 1% of the total position value.
  • Ignoring Fees: If you don't account for commission fees and overnight holding costs they can decrease your usable margin.
  • Relying on Estimates: Manual margin calculations may overlook minor discrepancies therefore traders should consistently use their broker's live margin calculator for exact results.
  • Not Including All Positions: Total margin requirements must reflect the sum of impacts from all open trading positions.
  • Using Incorrect Units: Trading errors occur when traders mix up standard margin requirements with those for mini lots which results in incorrect calculations.
  • Not Updating for Price Changes: Margin requirements need updates whenever price fluctuations occur and trading positions adjust.

You can minimize expensive margin-related trading errors by understanding frequent mistakes and thoroughly reviewing your work. BlueSuisse calculators remove all chances of error.
