How Forex Commission Is Calculated

Forex trading involves various costs, and commission is a significant one, particularly with ECN (Electronic Communication Network) brokers. Understanding how commissions are calculated is crucial for managing your trading expenses and evaluating the true cost of your trades. Unlike spread-only models, commission-based trading offers transparency regarding one component of your transaction costs.

What is Forex Commission?

Forex commission is a fee charged by a broker for executing a trade. It is typically applied in addition to the spread, which is the difference between the bid and ask price of a currency pair. Commissions are common in ECN or raw spread accounts, where brokers offer very tight, often near-zero, spreads directly from liquidity providers and charge a separate commission for their services.

This model contrasts with dealing desk or standard accounts, where the broker often widens the spread to include their profit margin, making the spread the primary cost.

How Commission is Calculated

Forex commission is most commonly calculated based on the volume of currency traded. This means the larger the trade size, the higher the commission. The calculation can be expressed in several ways, often as a fixed amount per standard lot, per million traded, or as a percentage of the notional value of the trade.

• Per Standard Lot: Many brokers quote commission as a specific dollar amount (or equivalent in other currencies) per standard lot (100,000 units of the base currency) traded. For example, a broker might charge $7 per round turn lot. A "round turn" refers to both opening and closing a position. So, $3.50 might be charged for opening and $3.50 for closing.
• Per Million Dollars Traded: This is a common method, especially among institutional traders or for quoting average costs. The commission is stated as a dollar amount per million units of the base currency traded. For instance, a commission of $40 per million means for every $1,000,000 in notional value traded, $40 is charged. This can be easily converted to a per-lot cost: $40 per million is equivalent to $4 per standard lot ($1,000,000 / 100,000 units = 10 lots, so $40 / 10 lots = $4 per lot).
• As a Percentage: Less common in retail Forex but sometimes seen, commission could be a small percentage of the total trade value.

Example Calculation

Let's consider a common scenario: a broker charges $7 per standard lot, round turn.

• If you trade 1 standard lot (100,000 units), the commission for opening and closing the trade will be $7.
• If you trade 0.1 standard lots (10,000 units, a mini lot), the commission would be $0.70.
• If you trade 0.01 standard lots (1,000 units, a micro lot), the commission would be $0.07.

These amounts are typically debited from your trading account when the position is opened and/or closed.

Factors Influencing Commission Rates

Several factors can influence the commission rates offered by a broker:

• Account Type: Different account types (e.g., ECN, standard, VIP) often come with varying commission structures. ECN accounts typically feature lower spreads and higher commissions, while standard accounts might have wider spreads and no explicit commission.
• Trading Volume: Some brokers offer tiered commission structures, where higher trading volumes qualify for lower per-lot commission rates.
• Currency Pair: While less common for commissions, some brokers might have slight variations for exotic pairs compared to major currency pairs.
• Broker Model: As mentioned, brokers operating with a pure ECN model tend to charge commissions, as their primary revenue comes from these fees rather than spread markups. RannForex, for example, operates on an ECN model and aims to provide competitive costs to clients. Some statistics show that RannForex clients can earn more compared to industry averages for brokers.
• Promotions and Rebates: Occasionally, brokers may offer temporary commission discounts or rebates as part of promotional campaigns.

Commission vs. Spread

It's important to understand the interplay between commission and spread when evaluating overall trading costs. A broker offering a very tight spread (e.g., 0.1 pips) but a high commission (e.g., $10 per lot) might be more expensive than a broker with a slightly wider spread (e.g., 0.8 pips) and a lower commission (e.g., $4 per lot) or no commission at all. Traders should always consider the total cost per trade.

Conclusion

Forex commission is a direct cost associated with executing trades, primarily found with ECN brokers. It is typically calculated based on the volume traded, often quoted per standard lot or per million dollars. Understanding this calculation is key to accurately assessing your trading expenses and choosing a broker that aligns with your trading strategy and cost preferences.
