Forex Trading Costs: Spreads, Commissions, Swaps and More

Trader reviewing forex pricing at workstation

Forex trading costs come from five places: the spread, the commission, the swap (overnight financing), slippage, and account-level fees such as currency conversion, inactivity, deposits and withdrawals. The first three are the ones you can calculate before you click. The last two only show up in your statement. This guide shows how each one works, how to add them into a single round-trip figure, and how to compare a spread-only account with a raw-spread-plus-commission account without being fooled by headline numbers.

TL;DR

  • Total cost of a trade = spread cost + commission + swap, plus slippage and account fees you only see afterward. Put everything in one currency before adding.
  • Spread-only accounts bundle the broker’s fee into a wider spread. Raw-spread accounts show a tight spread and charge commission separately. Neither is cheaper by default: it depends on the spread you actually get and how often you trade.
  • Active traders feel spreads and commissions most. Traders who hold for days feel swaps most.
  • Leverage does not change the dollar cost of a trade, but it makes that cost a much larger share of your margin.
  • Compare brokers on the all-in cost of your own typical trade, not on the lowest advertised number.

The five costs of a forex trade

A retail forex trade is not free just because there is no “fee” line. In the US, the CFTC’s customer advisory on retail forex points out that you trade against the dealer, and the dealer earns money when you trade more often, lose, or pay fees, spreads or commissions (CFTC customer advisory). The same advisory reports that about two-thirds of customers at registered OTC forex dealers lost money once credits, financing charges, fees and other expenses were counted. That is a good reason to know exactly what you pay.

Here is the full list.

Cost When you pay it How it shows up
Spread Every trade Difference between bid and ask, built into your entry and exit prices
Commission Every trade, on commission-model accounts A separate charge per lot
Swap (rollover/financing) When a position stays open past the daily rollover Credit or debit on your account
Slippage When your fill differs from the price you clicked Better or worse entry or exit price
Account fees Occasionally Currency conversion, inactivity, deposit or withdrawal charges

Spreads: the cost you pay on every trade

The spread is the gap between the price you can buy at (ask) and the price you can sell at (bid). Buy and you pay the ask; close immediately and you receive the bid. That gap is what you give up.

The cost in dollars is the spread in pips times the pip value times the number of lots. On EUR/USD, one pip on a standard lot (100,000 units) is worth about $10, so a 1.0-pip spread on one lot costs about $10. On a mini lot (0.1) the same spread costs about $1.

Behind the scenes, brokers source wholesale prices from liquidity providers and then either pass them on with a small markup or add their own. An Australian industry association describes the model this way: providers source wholesale pricing from liquidity partners, mark it up, and let retail clients trade (submission to ASIC). The size of that markup, and whether it sits inside the spread or is billed as a commission, is the whole difference between account types.

Two things to remember about spreads:

  • They are not fixed. Spreads widen around news releases, at rollover and in thin markets, and tighten when liquidity is deep. A quoted “average” spread is not the spread you get at 8:30 a.m. on a jobs-report Friday.
  • They differ by pair. Major pairs are usually the tightest. Crosses and exotics cost more, sometimes several times more.

Commissions: a separate, visible fee

Commission-model accounts quote a raw or near-raw spread and charge a fixed fee per lot. The detail that trips people up is the charging basis:

  • Per side: the fee is charged when you open and again when you close.
  • Round turn: one fee covers the open and the close.

A “$3.50 per lot” commission per side equals $7 per lot round turn. A “$7 per lot” commission can mean either, so read the fee schedule before comparing two brokers. Quoting one broker’s per-side number against another’s round-turn number is the most common way to misjudge cost.

Commission scales with size. Ten lots cost ten times one lot. Spread cost scales the same way, so the comparison between account types does not change with position size, but the absolute dollars do.

Swaps: the cost of holding overnight

When you keep a position open past the daily rollover, you pay or receive a swap based on the interest-rate difference between the two currencies, plus the broker’s financing markup. Day traders who close before rollover never see it. Swing and position traders do, every night, and a Wednesday rollover usually carries a triple charge to cover the weekend.

CME Group’s analysis of FX trading costs makes the point that for positions held a week or more, holding costs can become the most significant cost factor (CME Group). A trader who obsesses over a 0.2-pip spread difference and ignores a swap that runs a few dollars per lot per night is optimizing the wrong line.

Swaps can be positive. If you are long the higher-yielding currency, you may be credited. Rates change with central-bank policy, so check the live swap table in your platform rather than a number from an article.

Slippage and execution quality

Slippage is the difference between the price you expected and the price you got. It can help you or hurt you, and it is not on any fee schedule, but it is real cost. The Bank for International Settlements notes that executable prices depend on order size, liquidity and volatility, and that executing faster and more aggressively can cut exposure to price moves but raise market impact, while slower execution does the reverse (BIS). The BIS framing is useful for a retail trader too: headline spread and commission are only part of execution cost, so you should also track the slippage you actually experience.

Factors shaping forex execution costs

How to measure it: for a week of trades, compare the price on your screen when you pressed the button with the fill price in your history. Average the difference in pips, with sign. That number, not a marketing claim, is your real slippage.

Execution speed matters most to scalpers and news traders, because a few hundred milliseconds in a fast market can move the fill by a pip or more. For a closer look at what speed does and does not buy, see our piece on low latency trading.

Other fees to check before you fund an account

The CFTC advisory tells traders to look for currency conversion fees when trading instruments not denominated in the account’s base currency, deposit or withdrawal fees, and inactivity fees on dormant accounts (CFTC). Add to your checklist:

  • Conversion: if your account is in USD and you trade a pair whose profit is in another currency, the profit is converted. Ask what rate and what markup applies.
  • Deposits and withdrawals: the broker may charge nothing while the bank, card network or crypto network does. Check both sides.
  • Inactivity: some brokers charge a monthly fee after a period without trades.
  • Market data and platform fees: rare for MetaTrader users, but ask.

How to calculate your total round-trip cost

Use one formula and one currency:

Round-trip cost = spread cost + commission for the open and close + swap for the nights held

Set any component that does not apply to zero, and convert everything to your account currency before adding.

What about the spread being “paid twice”? It is not. If the market midpoint does not move, you buy at the ask and sell at the bid, and the round trip costs one spread, because those two prices already contain it. Do not double the quoted spread; add only the separately billed items on top.

Worked example: one lot of EUR/USD

These figures are illustrative, chosen to show the arithmetic, and are not a quote from any broker.

Account A: spread-only. Spread 1.3 pips, no commission, closed the same day.

  • Spread cost: 1.3 × $10 × 1 lot = $13
  • Commission: $0
  • Swap: $0
  • Total: $13 (1.3 pips)

Account B: raw spread plus commission. Spread 0.2 pips, commission $7 per lot round turn, closed the same day.

  • Spread cost: 0.2 × $10 × 1 lot = $2
  • Commission: $7
  • Swap: $0
  • Total: $9 (0.9 pips)

Now change one assumption. If that $7 is charged per side, commission becomes $14 and Account B totals $16 (1.6 pips), which makes Account A cheaper. Same headline numbers, opposite answer. That is why the charging basis matters.

Break-even rule of thumb

Convert commission to pips: on a standard lot, $10 of commission equals 1 pip. Add it to the raw spread. Whichever account has the lower all-in pip figure on the pair you trade, during the hours you trade, is cheaper. Sample the spread at your own session times, not the broker’s best-case average.

Add a holding period

Take Account B and hold one lot for four nights at a hypothetical $3 per night debit. Swap adds $12, so the total rises from $9 to $21. Holding costs can dwarf the spread difference between accounts, which is why the right account for a scalper is often the wrong one for a swing trader.

Spread-only vs raw spread plus commission: which costs less?

There is no universal winner. The two models differ in where the broker’s fee sits:

Spread-only (standard) Raw spread + commission
Fee location Inside a wider spread Separate line per lot
Transparency Lower: you see one number Higher: market spread and fee are split
Tends to suit Occasional traders, small sizes, simplicity Scalpers and high-frequency traders, larger sizes
Main risk Wide spreads at volatile times Misreading per-side vs round-turn commission

For traders who open many positions a day, the raw-plus-commission model often comes out cheaper, because the market spread on major pairs can be a fraction of a pip. For a trader who places a handful of trades a week and values a single easy number, the spread-only account is perfectly sensible. We go deeper on this in raw spread vs standard account, and on what the “ECN” label does and does not guarantee in ECN forex brokers.

Leverage makes costs matter more

Leverage does not change what a trade costs in dollars. It changes how large that cost looks next to your margin. ESMA’s analysis confirms that high leverage magnifies costs such as spreads, commissions and financing charges relative to margin, and can deplete a large share of it (ESMA). A $9 round trip is trivial against a $50,000 account and a visible bite against $500.

That also answers the question people often ask about small accounts. You can open a position with $100, but a small balance means every cost is a bigger fraction of capital, and a single normal move against you can use up a large part of the account. Size the trade so that cost and a reasonable stop-loss are both a small percentage of your balance.

Our perspective: cost is a pricing and speed question together

We built Mitra Markets around a simple belief: retail traders should see how they are charged and should get execution that does not quietly add to it. A tight spread is only worth something if the price is there when your order arrives, which is why we focus on low-latency execution under 30 milliseconds through our MitraNet™ technology and on direct access to Tier-1 liquidity.

On pricing, we publish a commission of $7 per lot and a 1.0 pip markup on our accounts page, so you can run the math above with our real figures instead of guessing. We also do not require a minimum deposit and we process instant deposits, which removes two common friction points before you even place a trade.

Our advice is the same whether you trade with us or not: pick the account that matches your trading frequency, test spreads at your own hours, track your slippage for a week on a small size, and only then scale up.

Run the numbers on our accounts

If you trade often and care about tight pricing, compare the commission-based and markup-based options side by side on our trading accounts page. You can see which fee applies, test it with the formulas above, and pair it with MetaTrader 5 for charting and algorithmic trading. The markets we offer cover forex, commodities, indices and crypto CFDs, so the same cost method works across instruments.

Volume traders can also look at Mitra Ascent Rewards, which rewards trading activity and can offset part of your costs. Trading CFDs carries a high risk of losing money, so size positions you can afford to lose.

How to lower your trading costs

  1. Match the account to your style. Frequent, short trades favor raw spreads; infrequent trades favor simplicity.
  2. Trade liquid pairs in liquid hours. Majors during the London and New York overlap generally carry the tightest spreads.
  3. Avoid market orders into news. Spreads widen and slippage rises around major releases.
  4. Mind your holding time. If swaps are eating your edge, shorten the trade or choose positions with a favorable carry.
  5. Keep a cost log. Record spread, commission, swap and slippage per trade for a month. The total, as a percentage of your gains, tells you whether your strategy has room to breathe.
  6. Compare derivatives honestly. If you hold for long periods, check whether another product suits you better, as covered in futures vs CFDs.

FAQ

Is $100 enough to start forex?

You can open an account and place very small trades with $100, especially with no minimum deposit requirement. The catch is that spreads, commissions and a normal adverse move take a much larger share of a small balance. Trade micro sizes, keep risk per trade to a small fraction of the account, and treat it as a way to learn rather than earn.

Is $500 enough to trade forex?

It gives you more room than $100, but the same logic applies: cost and risk per trade must stay small relative to the balance. At $500, a position that costs $9 in a round trip would be nearly 2% of the account before any price move, so use smaller lots.

Can you make $100 a day on forex?

Some days, yes, but it is not a reliable income target. The CFTC advisory reports that about two-thirds of customers at registered retail forex dealers lost money once costs were counted (CFTC). A daily dollar goal also pushes people to oversize trades, which raises both risk and cost.

Do I pay the spread twice on a round trip?

No. If the midpoint stays unchanged, buying at the ask and selling at the bid costs one spread in total. Commissions, swaps and conversion charges are added on top, and per-side commissions are charged on both the open and the close.
