Spread vs Commission: Which Account Type Costs Less for Your Trading Style

Forex accounts charge in two main ways. Some take only a spread. Others take a tighter spread plus a commission. Which one costs less depends on how you trade.

This guide gives you one formula to compare them, with hypothetical numbers. Use your broker's real figures when you do it for yourself.

What is the difference between a spread and a commission?

The spread is the gap between the buy and sell price, and a commission is a separate fee per trade. You pay the spread on every trade, and a commission only on accounts that charge one.

The Exness Help Center defines the spread as "the difference between a trading instrument's bid and ask prices" (checked 3 Nov 2026). You buy at the higher ask price and sell at the lower bid price.

A commission is often a fixed amount per lot. Many accounts quote it "per side", which means you pay it once to open and once to close.

The US regulator CFTC notes that a dealer "makes money when you trade more frequently, lose money, or pay fees, spreads, or commissions". Both are real costs.

See spread and commission in our glossary.

How do I calculate the cost of one trade?

Add the spread cost and the commission for a full round trip, open and close. Here is the formula for forex:

• Spread cost = spread in pips × pip value of 1 lot × lots
• Commission = commission per lot per side × 2 × lots
• Total cost = spread cost + commission

On EUR/USD, one pip on 1 lot is worth 10 USD. Our guide What is a pip? shows why. The pip value calculator gives it for other pairs.

Swap is a third cost if you keep a trade open overnight. This guide leaves it out, but it can matter for longer trades.

Which account costs less on one trade?

On the numbers below, the commission account costs less per lot. These are hypothetical figures, not any broker's real prices.

Both costs scale with lot size. At 0.1 lot, A costs 1.00 USD and B costs 0.70 USD. At 2 lots, A costs 20.00 USD and B costs 14.00 USD.

Where is the break-even point?

The commission account is cheaper only when its spread saving is bigger than its commission. Divide the round-trip commission by the pip value to find the point.

In our hypothetical example: 6.00 USD ÷ 10 USD per pip = 0.6 pips.

So Account B is cheaper when its spread is more than 0.6 pips tighter than Account A's spread. If A's spread fell to 0.5 pips, A would cost 5.00 USD per lot and B would still cost 7.00 USD.

Spreads move during the day. Compare the spreads you actually see at the times you trade.

How does my trading style change the answer?

Your style matters because the gap between the two accounts adds up with every trade. The more round trips you make, the more the per-trade difference counts.

Hypothetical example: 10 trades of 0.5 lot in a month, with the numbers above.

• Account A: 10 × 5.00 = 50.00 USD
• Account B: 10 × 3.50 = 35.00 USD
• Difference: 15.00 USD

For someone who makes many short trades, that gap repeats often. For someone who makes a few long trades, the spread and commission are paid less often. Swap may matter more to them.

None of this means you should trade more. Fewer trades cost less on either account.

What happens to spreads around news and quiet hours?

Spreads can widen sharply at certain times, while a commission stays fixed. That can change which account is cheaper on a given trade.

CMC Markets notes that "major economic news announcements could cause the spread to widen" (checked 3 Nov 2026). CME Group writes that around the daily rollover, "a spread of a fraction of a pip during liquid hours can expand to several pips".

Hypothetical example at a news release: A's spread widens to 2.0 pips and B's to 1.1 pips. A then costs 20.00 USD per lot and B costs 17.00 USD.

Our guide to forex market hours explains when spreads are usually widest.

Where does a rebate fit in?

A rebate lowers your total cost after the trade, on top of either account's normal pricing. It does not change the spread or commission you pay when you trade.

Rebates can differ by account type. A rebate can be counted per lot, or as a share of the spread or fee. So compare accounts on cost after rebate, not before.

The Exness page lists the account types we cover. It shows their rebates once rates are checked, and until then it says the rates are being verified. The rebate calculator then estimates your monthly amount from your lots. How it works explains who pays.

Crypto exchanges use maker and taker fees instead. Read maker vs taker fees for that side.

What else do traders ask about spreads and commissions?

Is a zero-commission account free? No. You still pay the spread, and often swap. The cost is inside the price.

Is the spread the same all day? No. Floating spreads change with market activity and news. Check them at the times you trade.

Where do I find my real costs? In your broker's contract specification and your trade history. Use the profit and loss calculator to see a trade before costs, then add them.

What is the short version?

Total cost per trade = spread cost + round-trip commission. A commission account is cheaper only when its spread saving beats its commission.

Run the numbers with your broker's real spreads at your trading times. Once rates are checked, compare cost after rebate on the Exness page.
