Every time you open a forex trade, you start slightly in the red. That is not a glitch. It is the cost of doing business, and it comes from the forex spread. The spread is the small gap between the price you can buy at and the price you can sell at. It is how most brokers earn their money. If you ignore it, you can lose a surprising amount to costs alone, especially with frequent trades.

This guide explains what a forex spread is, how to calculate its cost, and how to keep it low.
What Is a Forex Spread?
Every currency pair has two prices at any moment. The bid is the price at which you can sell the base currency. The ask is the price at which you can buy it. The ask is always a little higher than the bid. The difference between them is the forex spread.
For example, say EUR/USD shows a bid of 1.0850 and an ask of 1.0852. The spread is 0.0002. In forex terms, that is 2 pips. If you are new to this unit, read our explanation of what a pip is in forex trading.
The same idea exists in every market. You can find a general explanation of it on Wikipedia’s bid-ask spread page and in Investopedia’s definition of a spread.
Why You Start Every Trade “Behind”
Imagine you buy EUR/USD at the ask price of 1.0852. Right after entry, you could only sell at the bid price of 1.0850. So your position is already down 2 pips before the market has moved at all.
To break even, the market must move in your favor by at least the size of the spread. The tighter the spread, the sooner you break even.
How to Calculate the Cost of a Forex Spread
You can turn the spread into a dollar cost with a simple formula:
Spread Cost = Spread in Pips × Pip Value × Number of Lots
Here is an example. The spread on EUR/USD is 1.5 pips. You trade one standard lot, where a pip is worth about $10. The cost is 1.5 × $10 = $15. You pay $15 just to enter and exit that trade.
Now compare a smaller trade. With one micro lot, a pip is worth about $0.10. The same 1.5-pip spread costs only $0.15.
The cost scales with your size. If you trade often, these small amounts add up quickly.
Fixed Spreads vs. Variable Spreads
Brokers usually offer one of two types of spread.
Fixed Spreads
A fixed spread stays the same regardless of market conditions. It is easy to plan around. However, brokers offering fixed spreads may requote or reject orders during fast markets.
Variable Spreads
A variable spread changes with market conditions. It is often tighter when the market is calm and liquid. It can widen sharply during news events or thin trading hours. Most modern brokers use variable spreads.
Neither type is always better. What matters is the actual cost you pay at the time you trade.
Spreads vs. Commissions
Some brokers charge no commission and build their fee into the spread. Others offer very tight “raw” spreads and charge a small commission per lot instead.
To compare accounts, add both costs together. Suppose Account A has a 1.6-pip spread and no commission. Account B has a 0.2-pip spread and a commission equal to about 0.7 pips. Account B costs about 0.9 pips in total, so it is cheaper for frequent traders. Always compare the total cost, not just one number.
What Makes Forex Spreads Widen or Narrow?
Several factors move the spread throughout the day.
- Liquidity. When many buyers and sellers are active, competition tightens the spread. Major pairs like EUR/USD usually have the lowest spreads.
- Currency pair. Exotic pairs have less trading volume, so their spreads are wider. Our guide on currency pairs explains the difference between majors, minors, and exotics.
- Time of day. Spreads are tight during busy hours and wide during quiet ones. See our guide to forex trading sessions for the best windows.
- News events. Around major announcements, spreads can jump suddenly as liquidity providers pull back.
- Volatility. Fast, choppy markets tend to widen spreads.
- Rollover. Near the daily market rollover, spreads often spike for a short time.
How the Forex Spread Affects Your Trading Style
Scalpers and Day Traders
If you make many trades for small gains, the spread matters a lot. A 2-pip spread on a 5-pip target eats 40% of your potential profit. Our guide to day trading vs swing trading explains why costs weigh more on short-term traders.
Swing Traders
If you hold trades for days and target 100 pips or more, a 1-pip spread is a small share of your profit. Spreads still matter, but they are less important than they are for scalpers.
The Spread and Your Risk Management
The spread affects more than your entry. It also affects where your orders trigger.
A buy trade closes on the bid price. If the spread widens suddenly, your stop-loss can be hit even if the chart price barely moved. This is a common surprise for beginners during news events.
The spread also cuts into your risk-reward ratio. If your stop is 10 pips away and the spread is 2 pips, your true risk is closer to 12 pips. Always include the spread when you plan a trade.
How to Reduce Your Forex Spread Costs
- Trade major pairs. EUR/USD, USD/JPY, and GBP/USD usually have the tightest spreads.
- Trade during liquid hours. Use the London session or the London–New York overlap.
- Avoid trading right before or after big news. Wait until spreads settle.
- Compare brokers. Look at average spreads over time, not just the lowest advertised figure.
- Consider a raw-spread account. If you trade often, the total cost with commission may be lower.
- Trade less often. Fewer, better trades mean fewer times paying the spread.
Higher leverage does not change the spread, but it can magnify what a small cost means to your account. Review leverage and margin before you size up.
Common Forex Spread Mistakes
- Choosing a broker on “zero spread” claims. Zero-spread accounts often charge commissions or have other costs. Check the full fee list.
- Ignoring spreads on exotic pairs. A pair that looks attractive may cost several times more to trade than a major.
- Trading during rollover or thin hours. You may pay far more than usual.
- Forgetting the spread in your targets. Short targets and stops are especially vulnerable.
- Over trading. Every extra trade is another spread paid.
FAQ: Forex Spreads
What is a good spread in forex? For major pairs such as EUR/USD, spreads under about 1 to 1.5 pips during liquid hours are considered competitive. Raw spread accounts may be much lower, plus commission.
Why did my spread suddenly widen? The most common causes are news releases, market open or close, rollover, and low liquidity.
Do brokers make money from the spread? Yes. For many brokers, the spread is the main source of revenue, along with commissions and other fees.
Is a lower spread always better? Not always. Look at total cost, execution quality, and reliability. A tiny spread means little if orders are slow or frequently rejected.
Final Thoughts
The forex spread is a small number with a big effect over time. It decides how far the market must move before you break even. Learn to calculate it, trade when it is tight, and include it in every plan. Once you treat the spread as a real cost, you will make cleaner, better-priced decisions.
