When you open a leveraged forex position, your trading platform shows several numbers that can look confusing at first: Balance, Equity, Used Margin, Free Margin and Margin Level<\/strong>. Understanding the difference matters because these figures tell you how much of your account is committed to open trades and how much capacity remains for new positions or to absorb floating losses.<\/p>\n

For Indian traders, the simplest way to remember the concept is this: Used Margin is the amount tied up to support your open positions, while Free Margin is the equity that remains available after that margin requirement is accounted for.<\/strong> The exact margin requirement, leverage, conversion method and close-out rules depend on the broker, platform and instrument.<\/p>\n

Quick formula:<\/strong>
\nFree Margin = Equity \u2212 Used Margin<\/div>\n

What Is Margin in Forex Trading?<\/h2>\n

Margin is the amount of capital a broker requires you to commit as collateral when opening a leveraged position. You do not normally pay the full notional value of a leveraged forex position. Instead, a percentage of the exposure is reserved as margin.<\/p>\n

For example, if a broker requires 2% margin on a $100,000 position, the required margin would be approximately $2,000 before any applicable currency conversion, spread effects or broker-specific calculations.<\/p>\n

Margin is therefore not the same thing as a trading fee. It is better understood as capital allocated to support an open leveraged position. Brokers can also change margin requirements depending on the instrument, account type, position size, market conditions and their own risk rules.<\/p>\n

IG explains that margin is the deposit required to open a leveraged position and that brokers may increase margin requirements when they expect higher volatility. OANDA likewise describes margin as collateral used to maintain open positions.<\/p>\n

What Is Used Margin?<\/h2>\n

Used Margin<\/strong> is the portion of your account equity that is currently committed to support open leveraged positions. Think of it as capital reserved by the broker rather than money that you can freely allocate to another trade.<\/p>\n

The exact calculation varies. A simplified model is:<\/p>\n

Used Margin \u2248 Position Notional Value \u00d7 Margin Requirement<\/strong><\/div>\n

With 50:1 leverage, a simplified margin requirement is 2%. A $50,000 position would therefore require about $1,000 of margin. Actual broker calculations can involve the current price, account currency conversion, instrument-specific margin rates and tiered requirements.<\/p>\n

What Is Free Margin?<\/h2>\n

Free Margin<\/strong> is the portion of your equity that is not currently committed as margin for open positions. It is commonly the amount that can support additional positions or absorb floating losses, subject to the broker’s rules.<\/p>\n

The core formula is:<\/p>\n

Free Margin = Equity \u2212 Used Margin<\/strong><\/div>\n

OANDA uses the same basic relationship in its account examples: equity minus margin gives the available\/free margin. This means Free Margin can change continuously even when you do not open or close a trade, because floating profit and loss changes your equity.<\/p>\n

Balance, Equity, Used Margin and Free Margin Example<\/h2>\n

Suppose an Indian trader has a forex account with a balance of $5,000<\/strong>. After opening one or more positions, the trades are showing a floating loss of $150<\/strong>.<\/p>\n\n\n\n\n\n\n\n\n\n
Account Metric<\/th>\nExample<\/th>\n<\/tr>\n<\/thead>\n
Balance<\/td>\n$5,000<\/td>\n<\/tr>\n
Floating P\/L<\/td>\n\u2212$150<\/td>\n<\/tr>\n
Equity<\/td>\n$4,850<\/td>\n<\/tr>\n
Used Margin<\/td>\n$1,200<\/td>\n<\/tr>\n
Free Margin<\/td>\n$3,650<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The calculation is:<\/p>\n

Equity = $5,000 \u2212 $150 = $4,850<\/strong><\/p>\n

Free Margin = $4,850 \u2212 $1,200 = $3,650<\/strong><\/p>\n

So although the account balance still displays $5,000, the trader’s actual equity is $4,850 because of the floating loss. The amount available after the existing margin requirement is $3,650.<\/p>\n

Why Free Margin Changes During an Open Trade<\/h2>\n

One of the most important points is that Free Margin is dynamic. It is not necessarily a fixed amount that remains unchanged after opening a trade.<\/p>\n

If an open position moves into profit, equity can increase and Free Margin can rise. If the position moves into loss, equity falls and Free Margin can decline.<\/p>\n

That is why watching only your balance can give you a false sense of security. Your balance may remain unchanged while an open position accumulates a significant floating loss.<\/p>\n

What Is Margin Level?<\/h2>\n

Many forex platforms, including MetaTrader-style platforms, also display Margin Level<\/strong>. A commonly used formula is:<\/p>\n

Margin Level % = (Equity \u00f7 Used Margin) \u00d7 100<\/strong><\/div>\n

Using the example above:<\/p>\n

Margin Level = ($4,850 \u00f7 $1,200) \u00d7 100 = 404.17%<\/strong><\/p>\n

A higher margin level generally indicates more equity relative to the margin committed to open trades. A falling margin level means the account is becoming more heavily stressed by losses, additional exposure or changing margin requirements.<\/p>\n

However, do not assume that one universal margin-level percentage applies to every broker. Margin-call and forced-liquidation thresholds are broker-specific. OANDA, for example, documents its own margin close-out methodology, while other brokers can use different thresholds and terminology.<\/p>\n

How Leverage Affects Used Margin<\/h2>\n

Leverage and margin are closely related. In a simplified example, 50:1 leverage corresponds to a 2% margin requirement, while 20:1 leverage corresponds to a 5% margin requirement.<\/p>\n\n\n\n\n\n\n\n\n
Leverage<\/th>\nSimplified Margin Requirement<\/th>\nMargin on $100,000 Exposure<\/th>\n<\/tr>\n<\/thead>\n
10:1<\/td>\n10%<\/td>\n$10,000<\/td>\n<\/tr>\n
20:1<\/td>\n5%<\/td>\n$5,000<\/td>\n<\/tr>\n
50:1<\/td>\n2%<\/td>\n$2,000<\/td>\n<\/tr>\n
100:1<\/td>\n1%<\/td>\n$1,000<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

These are simplified illustrations, not universal broker rates. The actual margin requirement for a particular account and instrument must be checked with the broker.<\/p>\n

Higher leverage can reduce the margin needed to control a given notional position, but it does not make the underlying market exposure safer. A small amount of capital can control a large position, meaning relatively small market moves can create significant gains or losses.<\/p>\n
