Commission vs spread describes the two different ways forex brokers charge for trade execution: a flat per-lot fee versus a built-in markup on the buy and sell price. Choosing between account types built around one or the other affects total cost differently depending on trading style, as this FXM680 guide explains.

What Is The Commission vs Spread Difference? An Overview
Commission is a fixed fee a broker charges per lot traded, billed separately from the market price. Spread is the gap between the bid and ask price, built directly into the quote itself. Brokers generally choose one primary model per account type: a wider spread with no commission, or a much tighter spread paired with an explicit commission charge.
Both models generate revenue for the broker, but they distribute cost differently across a trade. Spread cost is invisible in the sense that it is baked into the price a trader sees, while commission appears as a clear, separate line item in trade history.
Neither model is universally cheaper. The better choice depends on trade frequency, position size, and how a trader prefers to see cost represented.
Why This Difference Matters for Traders
High-frequency traders and scalpers often prefer commission-based accounts with raw, near-zero spreads, since predictable flat fees are easier to calculate across many small trades. Traders who place fewer, larger trades may find a standard spread-only account simpler, since there is no separate commission to track.
Understanding both models also matters when comparing brokers, since a broker advertising an extremely low spread may still be more expensive overall once commission is added, and vice versa.
Detailed Analysis of Commission and Spread Models
Spread-Only Accounts
Standard accounts typically widen the spread slightly to cover the broker’s cost, meaning the trader pays entirely through the price gap with no additional per-lot charge, and no separate line item to track.
Commission-Based Accounts
Raw spread and ECN accounts pass through spreads close to the true interbank rate, often close to 0.0 pips on major pairs, and instead charge a fixed commission per lot, typically a few dollars per side.
Blended Cost Comparison
To compare fairly, a trader must add the spread cost and commission together for each model and compare the combined total, not just one number in isolation.
| Model | Spread Size | Commission | Best Suited For |
|---|---|---|---|
| Standard Account | Wider, built-in cost | None | Occasional, longer-term traders |
| Raw/ECN Account | Very tight, near-market | Fixed per lot | Scalpers, high-frequency traders |
Step-by-Step Guide to Comparing the Two Models
- Note the standard account’s average spread for the currency pair being traded.
- Note the raw/ECN account’s spread for the same pair, plus its per-lot commission.
- Convert both totals into the same unit, typically dollars per standard lot round-turn.
- Multiply by expected monthly trade volume to see which model is cheaper at that frequency.
- Re-check the comparison periodically, since spreads and commission rates can change over time.
Common Pitfalls to Avoid
A common pitfall is judging a broker purely by a headline “0.0 pip spread” claim without checking the accompanying commission, which can make the account far more expensive than it first appears. Another is assuming commission is always worse than spread, when for high-volume traders a tight commission-based account is frequently the cheaper option overall.
Frequently Asked Questions
Is commission always more expensive than spread? Not necessarily; the cheaper option depends on trade frequency and size, and must be calculated as a combined total rather than compared in isolation.
Can an account charge both spread and commission? Yes, most raw spread and ECN accounts still carry a small residual spread on top of the commission, just much tighter than a standard account.
Which model is better for beginners? Standard spread-only accounts are often simpler for beginners since there is one visible cost to track rather than two separate figures.
