How to compare forex broker spreads (without getting fooled by the headline number)

The spread is the price of trading — and the number is rigged

The spread is the gap between the price you can buy at and the price you can sell at. It's how most brokers earn, and on every trade you pay it twice — once getting in, once getting out. So a tighter spread genuinely saves you money. The problem is that broker spread tables are marketing documents. The "from 0.0 pips" headline is real but rare, and comparing two brokers on their advertised numbers will mislead you almost every time. Here's how to compare them properly.

Minimum spread vs typical spread

The first trick is the word "from". "Spreads from 0.0 pips" means the best spread the broker has ever shown, on its tightest account, on the most liquid pair, at the calmest moment. You will almost never trade at it.

What you actually pay is the typical or average spread — the one you get most of the time. A serious comparison uses typical spreads, not minimums. If a broker only publishes "from" numbers and won't show typical spreads, that itself is a signal. Where you can, look for an average spread measured over a period, ideally during the hours you'll trade.

Spread plus commission — the real cost

The second trick is comparing a commission-free account against a commission account on spread alone. A raw or ECN account shows a tiny spread but charges a separate commission per trade; a standard account shows a wider spread and no commission. Compare them on spread alone and the raw account always "wins" — wrongly.

To compare fairly, convert everything to one number: total cost per trade. Take the spread, add the commission expressed in the same units, and compare the totals. A common rule of thumb is that a round-turn commission of about $6 per standard lot equals roughly 0.6 pips on a major pair — so a "0.0 pip + commission" account is really costing you around 0.6 pips, which may or may not beat a standard account's 0.8–1.0 pip all-in spread. Do the addition; don't trust the headline.

Compare the same pair at the same time

Spreads vary by pair and by time of day. EUR/USD is the tightest market in the world; exotic pairs can be ten or twenty times wider. And every pair widens when liquidity is thin — around major news releases, and at the daily rollover when the market briefly thins out.

So compare like with like: the same currency pair, ideally during the active trading session you'll use (the London–New York overlap is the most liquid for major pairs). A broker that looks cheap on EUR/USD at midday London may be expensive on the pairs and hours you actually trade.

Fixed vs variable spreads

Most brokers offer variable spreads that move with the market — tight when liquidity is high, wider when it's thin. A few offer fixed spreads that stay constant. Fixed spreads are predictable and can be reassuring for beginners, but you usually pay for that certainty with a wider average. Variable spreads are cheaper most of the time but blow out during news. Neither is "better" — it depends on whether you trade around news (avoid fixed's premium) or want predictable costs (accept it).

Watch the cost around news and rollover

If your strategy holds positions through news or overnight, the average spread tells only half the story. Spreads can widen dramatically for a few seconds around a major release, and the overnight swap (the interest charge for holding a leveraged position past rollover) is a separate cost entirely. A broker with a great average spread but punishing swaps can be the wrong choice for a swing trader. Check the swap rates on the pairs you'll hold, not just the spread.

A simple way to compare two brokers

Put them side by side on a single realistic scenario. Pick the pair you trade most, your usual position size, and your typical session. For each broker, work out: typical spread cost for that size, plus commission if any, plus swap if you'll hold overnight. That single total cost per round-turn trade is your comparison number. Repeat it for one or two other pairs you trade, and the genuinely cheaper broker — for your trading — becomes obvious. It's often not the one with the flashiest "from 0.0" banner.

What "good" looks like

As a rough guide for a major pair like EUR/USD, an all-in cost (spread plus any commission) of around 0.6–1.0 pips is competitive for retail; consistently below that is excellent; consistently above it on the majors is expensive. But the number that matters is always your all-in cost on your pairs at your times — not the broker's best-case headline.

This is precisely how we compare brokers at CompareFX: typical spreads on real pairs, spread plus commission as one all-in figure, and swaps for traders who hold overnight — on top of the regulation and protections that come first.
