The most obvious cost is the fee charged by the broker or exchange.

Futures operate in an all-to-all market structure. The exchange acts as a central meeting place where all participants – from retail traders to the largest banks – trade on equal terms. To maintain this infrastructure, the exchange charges a transaction fee. Brokers supporting customers trading futures will also charge a commission fee for their services. In our TCA, the total direct transaction fee for futures across the trade lifecycle was $6.47.

CFDs are “over-the-counter” (OTC) instruments. The broker is the marketplace. To attract users, many CFD brokers offer “commission-free” trading or very low entry fees. Our analysis showed a lower average direct fee of $1.91 for CFDs.

The bid-ask spread is the difference between where you can buy from the market (the ask) and where you can sell to the market (the bid). If you buy and immediately sell, the money you “lose” is the spread.

In futures, the spread is determined by the aggregate of all market participants. Because thousands of traders are competing to offer the best price, the spread is typically very tight. Our TCA calculated the bid-ask cost for futures at $7.50.

In CFDs, the broker sets the spread. They must compensate themselves for the risk of taking the other side of your trade. Consequently, CFD spreads are almost always wider than those on a centralized exchange. Our analysis found an average spread cost of $8.71 across major retail brokers.

There is a critical strategic difference here. In the all-to-all futures market, an investor can be a “price maker” rather than a “price taker.” Instead of buying at the current ask, you can place a limit order at the bid. If the market comes to you, you avoid paying the spread entirely and may even “earn” it. In our analysis, this would mean receiving $7.50 rather than paying it, and reducing the overall cost substantially.

With CFDs, the market rules are set by the broker – passive trading is only possible if they permit it.  This would be equivalent to the broker paying the customer for their transaction – any rules that indicate that passive trading is possible should be studied carefully.

Because both futures and CFDs are leveraged, you are essentially trading with borrowed capital. This incurs an interest cost, often called “carry” or “financing.”

CFDs treat this as an explicit daily charge. If you hold a position past the daily “roll” (usually 5:00 p.m. ET), the broker applies a “swap” fee to your account. This rate is determined by the broker and often includes a markup or administrative margin. The precise calculation process varies from broker to broker, and is pretty obaque. 

In contrast, futures handle this implicitly. The cost of carry is baked into the price of the contract itself. Because futures represent a price at a future date, the difference between the “spot” price and the “futures” price naturally reflects the interest rate differential between the two currencies.

Our TCA revealed a staggering difference in efficiency:

• FX futures holding cost: $8.65 per day.
• CFD holding cost: $12.59 per day.

The CFD holding cost was nearly 50% higher than the futures equivalent. For a trader holding a position for a week or more, this “leakage” becomes the most significant cost factor in their entire strategy.

When we aggregate these three pillars: direct fees, spreads and holding costs, a clear trend emerges.

While CFDs appear cheaper at the moment of execution due to lower direct transaction fees, the advantage quickly evaporates.

1. For day traders: If you can utilize “passive” limit orders in the futures market, futures are cheaper from the very first minute.
2. For swing traders: For any position held for one day or longer, the superior financing rates of the futures market make them the more economical choice. The 50% premium paid on CFD financing acts as a heavy drag on long-term portfolio growth.

Ultimately, the centralized structure of a futures exchange offers a level of transparency and competitive pricing that provides a distinct advantage over the CFD dealer model. For the non-professional investor, futures represent a highly efficient vehicle where lower ongoing costs allow more capital to remain at work in the market.
