Forex spreads get the homepage treatment. The other two trading costs do not. That is not an oversight. It is the business model. Commissions and swaps get a footnote in the fee schedule that almost nobody opens.
Here is the fix. Every forex trade carries up to three charges. A simple formula reveals the true cost per trade in under a minute. This article gives you that formula and the real numbers behind each forex commission, forex spread, and forex swap. It also gives you a direct answer on which account model fits how you trade.
| Cost | What it is | When it applies |
|---|---|---|
| Spread | The gap between the bid and ask price, built into the quote | Every trade, every time, win or lose |
| Commission | A flat fee per lot, charged separately from the spread | Trades on raw-spread and some hybrid accounts |
| Swap | Daily interest charged or credited for holding past rollover | Any position open past the daily cutoff, typically 21:00 to 22:00 GMT |
Most retail traders pay at least one of these costs on every trade, and usually two or three. The broker decides which one to advertise, based on where it is most competitive. The other two sit quietly in the account specs. Comparing brokers on the headline number alone means comparing brokers on the one number they chose to show you.
Forex Spreads: The Built-In Markup
Forex spreads are the cost every trader sees first, and the cost most never question. Spread is the difference between the bid price and the ask price. If EUR/USD quotes 1.08500 bid and 1.08512 ask, the spread is 1.2 pips. You buy at the ask and sell at the bid. Every round-trip trade pays the spread once, whether it wins or loses.
Brokers source pricing from liquidity providers, mostly large banks and non-bank market makers. They add a markup before quoting clients, and that markup is the broker’s revenue. On a commission-free account, the markup sits entirely inside the spread. On a raw-spread account, the broker extracts that markup as a separate commission instead. The spread then sits close to the real interbank rate.
Three spread types show up in retail accounts. Variable spreads move in real time with market liquidity. They tighten during the London-New York overlap and widen around news and during the Asian session. Raw spreads start near zero and pair with a separate commission. Fixed spreads stay constant regardless of conditions, but they typically run higher than variable spreads at peak liquidity. Brokers often reserve the right to requote fixed-spread accounts during fast markets.
Commission: The Honest Fee
Commission is a separate, flat fee charged per trade. Brokers usually quote it per standard lot, per side, or per million currency units traded. A common structure runs 3 to 7 dollars per standard lot per side. That puts the round-trip cost at 6 to 14 dollars per lot. The fee is fixed and predictable, which is exactly why active traders often prefer it to spread-based pricing.
Here is the part the marketing skips. An account labeled commission is often cheaper in total than one labeled commission-free. A commission-free account with a 1.2 pip spread costs 12 dollars per round-trip lot. A raw-spread account with a 0.1 pip spread, plus a 7 dollar commission, costs 8 dollars per lot. Same trade, same broker family, 4 dollars different. Multiply that across hundreds of trades a year, and the gap between these forex spreads compounds into thousands of dollars.
Swap: The Overnight Tax Nobody Calculates
Swap is the interest charge or credit applied to any position held past rollover. That cutoff typically sits around 21:00 to 22:00 GMT, depending on the time of year. The amount comes from the interest-rate differential between the two currencies in the pair. Hold the higher-rate currency, and you receive a credit. Hold the lower-rate currency, and you pay a debit. Brokers add their own margin on top of that differential. Most retail positions therefore pay a small daily debit regardless of direction.
The numbers look small per night and turn ugly per month. A typical EUR/USD position might cost 3 to 7 dollars per night per standard lot. Held for a week, that runs 21 to 49 dollars. Held for a month, it climbs to roughly 90 to 210 dollars. For a swing trader running multiple positions, swap can exceed the entire spread cost for the period. For a position trader holding for months, swap can exceed the whole profit on a modest move. Almost nobody calculates this in advance, which is exactly why brokers rarely feature swap rates in marketing.
The Three Account Models, Side by Side
Forex spreads alone do not tell you which account model wins. The headline numbers across account types look very different. The total costs sit much closer together than the marketing suggests. The right pick depends entirely on how you trade.
| Account model | Typical EUR/USD spread | Commission | Round-trip cost, 1 lot | Best fit |
|---|---|---|---|---|
| Commission-free | 1.0 to 1.5 pips | None | $10 to $15 | Swing traders, lower frequency, simplicity |
| Raw spread plus commission | 0.0 to 0.3 pips | $3 to $7 per side | $6 to $14 | Scalpers and active day traders |
| Fixed spread | 1.5 to 2.0 pips | None | $15 to $20 | Traders who specifically trade around news, for predictability |
A scalper running standard lots saves real money on raw spread plus commission. A swing trader running smaller size and fewer trades sees only a minor difference either way. Commission-free stays simpler to track at that lower volume. A fixed-spread account only earns its higher base cost during news releases. That is where variable spreads widen far more than the fixed rate does.
How to Calculate the True Cost of a Trade
The formula is short. Total cost equals spread cost, plus commission, plus swap multiplied by nights held. Run it before you pick a broker, on a raw spread account or any other model. It takes thirty seconds and reveals the true cost per trade more reliably than any marketing page.
Take a typical EUR/USD position on a raw-spread account, held 3 nights. The spread costs 2 dollars. Commission adds 7 dollars. Swap adds 16.50 dollars across the 3 nights. Total cost lands at 25.50 dollars per round-trip trade. Run the identical trade on a commission-free account with a 1.2 pip spread and a similar swap profile. That total comes to 12 dollars plus 16.50 dollars, or 28.50 dollars. The raw-spread model wins by 3 dollars on this trade.
That gap looks small until you scale it. Multiply 3 dollars across 200 trades a year, and the difference reaches 600 dollars. On a 5,000-dollar account, that is a 12 percent annual headwind from account choice alone. Neither trader has made a single directional decision yet. The math is not exciting. The compounding is.
Forex Spreads Behavior Across the Trading Day
Forex spreads are not fixed in practice, even on accounts marketed as stable. Headline spreads describe peak liquidity, nothing more. The same pair, on the same broker, on the same day, can swing through an order of magnitude in spread. It all depends on when you trade.
| Window | What happens to spreads | Why |
|---|---|---|
| Asian session | Wider than average | European and US banks are mostly closed, liquidity comes from a smaller pool |
| London open | Compressing | European liquidity arrives and depth increases |
| London-New York overlap | Tightest of the day | Maximum liquidity from both regions at once |
| Rollover, 21:00-22:00 GMT | Brief widening | Banks square positions for the daily cutoff |
| Major news releases | Dramatic widening | Liquidity providers pull quotes ahead of volatility |
A trader who systematically works the overlap pays meaningfully less than one running the identical strategy at low-liquidity hours. That holds true even on the identical account. The strategy does not change. The bill does.
Which Cost Structure Fits Which Trader
There is no universally best account model. The best account produces the lowest total cost for how you actually trade. It does not produce the lowest cost for how the marketing assumes you trade.
| Trader type | Best-fit structure | Why |
|---|---|---|
| Scalper, high trade frequency | Raw spread plus commission | Tight spreads dominate at high volume; the fixed commission becomes the smaller line item |
| Swing trader, moderate frequency | Commission-free | Simpler tracking, the cost gap versus raw spread is minor at lower volume |
| News-event trader | Fixed spread | Predictable cost when variable spreads would otherwise blow out |
| Position trader, multi-week holds | Swap-free or low-swap account | Cumulative overnight charges often exceed any spread premium on long holds |
The right answer changes with the trader, not the broker. The same broker can run cheap for one client and expensive for another on the identical pricing sheet. The honest comparison takes your last 100 trades. Model each one against a candidate broker’s full pricing, swap included, then compare the total. Anyone claiming a broker is universally cheapest is selling, not advising.
A note on choosing where to test this. TradeSetGoBrokers.com, an FSA Seychelles-licensed broker under Securities Dealer Licence No. SD249, publishes both a commission-free and a raw-spread tier. That makes it a reasonable place to run the same 100-trade comparison yourself. Whatever broker you use, verify the published spread, commission, and swap figures against your own trade history. Never just trust the marketing page.
The Zero Spread Marketing Trap
Few forex spreads claims get less scrutiny than the 0.0 pip headline. Brokers advertising 0.0 pip spreads are not lying outright. They are making a narrow technical claim that often disconnects from your real trading experience.
| Check | The question to ask | Why it matters |
|---|---|---|
| Account tier | Which account actually offers the 0.0 pip rate? | The headline tier is often the highest minimum deposit, not your account |
| Time window | During which hours does that spread really apply? | 0.0 pips at 3 am London time means little if you trade the overlap |
| Attached commission | What commission comes with this spread? | The 0.0 pip number frequently hides the real cost one line down |
Once those three answers are clear, calculate the actual total cost. Compare it against alternatives on equal terms. The 0.0 pip headline is not deceptive by itself. It becomes deceptive only when a trader treats it as the complete picture.
Swap-Free Accounts: When They Make Sense
Swap-free accounts, sometimes called Islamic accounts, remove the overnight interest charge. A swap-free account exists for traders whose religious observance prohibits paying or receiving interest. The same structure helps any position trader holding for weeks, regardless of religious considerations. It removes the cumulative drag that swap creates on long-duration trades.
The tradeoffs are real, not hidden. Brokers typically replace swap with one of three alternatives. A wider spread on the swap-free account is the most common alternative. Some brokers instead charge an administrative fee or restrict the instrument list. Some brokers offer genuinely free swap-free accounts in specific jurisdictions. Others apply the structure only conditionally. Always check the full fee schedule before assuming the account removes cost rather than relocating it.
For position traders, the math is direct. Hold positions for more than 5 nights, and the math flips. Cumulative swap on a standard account often exceeds any spread premium on the swap-free version. That makes the swap-free option cheaper overall for that holding period. Day traders who exit before rollover get no benefit from swap-free accounts. Any wider spread there is pure added cost.
Frequently Asked Questions
What is the spread in forex?
The spread in forex is the difference between the bid price and the ask price for a currency pair. You buy at the ask and sell at the bid, so every round-trip trade pays the spread once. It is the most visible cost on a retail platform. Traders quote it in pips, the smallest standard price increment for that pair.
What are good forex spreads?
Competitive forex spreads depend on the pair and the hour, not a single universal number. For EUR/USD during peak liquidity, a typical commission-free spread runs 0.8 to 1.5 pips. On a raw-spread account, it runs 0.0 to 0.3 pips before commission. Anything above 2 pips on EUR/USD during peak hours counts as uncompetitive. Minor and exotic pairs carry wider expected spreads, and the right benchmark depends on the specific pair.
How are forex spreads calculated?
The spread is the ask price minus the bid price. EUR/USD quoted at 1.08500 bid and 1.08512 ask gives a spread of 1.2 pips. To convert that into a dollar cost, multiply the spread in pips by the pip value of your trade size. On a standard lot of EUR/USD, the pip value is 10 dollars. A 1.2 pip spread costs 12 dollars per round-trip trade.
How does spread affect profit in forex?
Spread is a starting deficit on every trade. Price has to move in your favor by at least the spread distance before the position breaks even. For a scalper targeting a 5 pip move, a 1.2 pip spread consumes 24 percent of the target. For a swing trader targeting 100 pips, that same spread is just 1.2 percent. Spread matters in direct proportion to how small your target move is.
What is a swap in forex trading?
A swap is the daily interest charge or credit applied to any position held past rollover. That cutoff typically sits around 21:00 to 22:00 GMT. It reflects the interest-rate differential between the two currencies, plus a margin the broker adds on top. Most retail positions pay a small daily debit regardless of direction. Held for weeks or months, the cumulative effect can exceed the spread cost.
How are overnight swaps calculated?
Brokers publish swap rates per standard lot per night, separately for long and short positions on each pair. Multiply the published rate by your position size relative to a standard lot, then by nights held. Wednesday rollover typically triples the swap to cover the weekend in advance. Always check your broker’s published rates before holding a position overnight.
What is the difference between commission and spread?
Spread sits built into the price shown on the platform. Commission is a separate, flat fee charged per trade. A commission-free account recovers its cost entirely through a wider spread. A raw-spread account keeps spreads tight and charges a separate commission instead. The total cost is what matters, not which piece is easier to see.
How do raw-spread accounts work?
Raw-spread accounts pass the interbank market spread through to the trader with little or no markup. A separate commission then applies per trade. Typical raw spreads on major pairs run 0.0 to 0.3 pips. Commissions add 3 to 7 dollars per standard lot per side. Total cost usually beats a commission-free account for active traders. The per-trade fee can discourage very small or infrequent trading.
Are zero-spread accounts actually zero?
Sometimes, during peak liquidity, on specific account tiers, with a separate commission attached. The 0.0 pip headline is technically accurate within a narrow definition. It rarely captures the full cost a trader actually pays. Always calculate total cost including commission. Check what spreads actually look like during the hours you trade, not just the marketed best case.
How do I avoid high spreads in forex?
Avoiding wide forex spreads is mostly a matter of timing, not broker choice. Trade during the London-New York overlap, roughly 12:30 to 16:00 GMT. Avoid the Asian session, the minutes around major scheduled news, and the rollover window. Choose major currency pairs over minors and exotics for tighter spreads. A raw-spread account gives frequent traders a structurally tighter spread than a typical commission-free account.
