Forex trading costs: Spreads, commission, and swaps

Trading costs can include spreads, commissions, and swaps, depending on your account type and how long you hold a position. While many traders focus on the spread, it's only one part of the total cost.

At Exness, trading costs can vary depending on your account type. Standard and Pro accounts include costs in the spread, with no trading commission. Raw Spread and Zero accounts offer tighter or near-zero spreads on selected instruments, with commissions charged separately. However, overnight swaps may also apply.

This guide explains the main components of trading costs—from spreads and commissions to swaps and account-related fees—so traders can compare costs more accurately before trading. 

Why understanding the full cost of a forex trade matters

Trading costs can add up quickly, especially for traders who trade frequently, use larger position sizes, or hold positions for longer.

That's why it's important to compare the total cost of the same trade, instrument, position size, and holding period. The Exness calculator can help estimate margin, pip value, spread costs, swaps, commissions, and potential profit or loss before you trade.

Cost component 1: Spread 

The spread is the difference between the bid (sell) and ask (buy) price.

It's also one of the first trading costs you'll encounter. If EURUSD has a bid of 1.0840 and an ask of 1.0841, the spread is one pip. Before the trade can move into profit, the price must first cover that cost.

How spreads are expressed

Forex spreads are usually expressed in pips. For most major forex pairs, one pip is the fourth decimal place. For JPY pairs such as USDJPY, the pip is usually the second decimal place.

How to calculate the spread cost

The basic formula is: spread cost = spread in pips × pip value × lot size

The Exness calculator can estimate pip value, spread, margin, commission, swap, and other values based on instrument, account type, lot size, and leverage.

What moves the spread?

Spreads fluctuate with market conditions, including liquidity, volatility, the trading session, and the instrument.

Major pairs such as EURUSD, GBPUSD, and USDJPY often have tighter spreads because they are traded more heavily. Less liquid pairs typically have wider spreads.

Spreads can also widen during quieter trading periods, market opens and closes, holidays, or major economic releases. Traders can use the Exness economic calendar to keep track of upcoming events.

Spreads on Pro accounts at Exness

The Pro account is designed for traders who prefer commission-free pricing. On Pro, trading costs are primarily reflected in the spread, with swaps applying only to positions held overnight. That said, at Exness, top-traded instruments are available completely swap-free.

According to Exness market-comparison data, spreads on major and minor forex pairs are 50% lower than the industry average.1

Cost component 2: Commission 

Commission is a fixed fee charged separately from the spread. It is common on raw spread accounts, where spreads may be tighter, but commission applies.

At Exness, Standard and Pro accounts are commission-free, while Raw Spread and Zero accounts charge commission. That’s why traders should compare the total cost, not the spread alone.

When Exness applies commissions

Commissions apply to Raw Spread and Zero accounts, but not Standard or Pro accounts.

As a result, traders should compare total trading costs rather than spreads alone.

• Pro: Spread + swap (if held overnight)
• Raw Spread / Zero: Spread + commission + swap (if held overnight)

How to calculate commission cost

The basic formula is:

Commission cost = commission per lot × lot size × 2

For example, if the commission is USD 3.50 per lot per side, the total commission is 7 USD for one lot, 3.50 USD for 0.5 lots, and 14 USD for two lots.

How to compare commission accounts with spread-only accounts

To compare account types accurately, traders should look at the total cost of the same trade. A tighter spread may appear more cost-effective at first glance, but you must also include commission.

The right account depends on trading style, trade size, frequency, and holding period. Traders can review Exness Standard accounts and Pro accounts, then use the calculator to estimate costs.

Cost component 3: The overnight swap 

A swap is a charge or credit applied when a leveraged position is held overnight. It is based on the interest rate difference between the currencies in a forex pair, along with the applicable trading conditions.

What is a swap in forex?

When trading forex, you're buying one currency and selling another. Because each currency has its own interest rate, holding a leveraged position overnight can result in a swap charge or credit.

How swap is applied

The swap is typically applied at daily rollover and may be charged or credited depending on the instrument and trade direction.

To account for the weekend, a triple swap is often applied on a specific day of the week—usually Wednesday for forex pairs. Positions closed before rollover generally do not incur swap charges.

When does swap matter?

Swap is most relevant for trades held overnight. While it may have little impact on short-term trades, it can become more significant for larger positions, longer holding periods, or trades that pass through a triple-swap rollover.

Can swap be positive?

Yes. Depending on the trade’s direction and interest rate differential, traders may receive a swap credit for holding a position overnight.

Where to check the swap costs at Exness

Traders can check swap costs in each instrument’s contract specifications and by using the Exness calculator. The calculator can estimate swap short and swap long rates before opening a trade.

For traders comparing account types, the swap should be considered with the spread and commission. A low entry cost can still become more expensive if held over several rollover periods.

Cost component 4: Other costs

Beyond spreads, commissions, and swaps, traders should also consider possible currency conversion costs or third-party payment provider fees. 

At Exness, deposits and withdrawals are completely free from any in-house costs. That said, funding conditions can vary by region, account currency, and payment method, so traders should check the latest details in their Personal Area before depositing or withdrawing.

How to calculate the full cost of a forex trade at Exness

The total cost of a trade depends on your account type and whether the position is held overnight.

• Pro: Spread + swap (if held overnight)
• Raw Spread / Zero: Spread + commission + swap (if held overnight)
• Standard: Spread + swap (if held overnight)

For short-term trades, spreads and commissions are usually the main costs. For positions held overnight, the swap should also be included. As position size increases, pip value and commission become more significant.

The Exness calculator can help estimate these costs when comparing instruments like DXY, EURUSD, USDJPY, and GBPJPY.

How account types change the cost structure

Standard and Pro accounts are commission-free, with trading costs built into the spread. Raw Spread and Zero accounts use a commission-based model, offering tighter spreads with commission charged separately.

The right account depends on your trading style. Traders who prefer simple pricing may choose commission-free accounts, while those focused on cost per trade may prefer raw spread accounts. For overnight positions, always consider the swap.
