What Is Spread in Forex? Beginner Guide to Costs (2026)

Introduction

If you are new to forex, one of the first questions you'll meet is: what is spread in forex? The spread is fundamental because it is an immediate trading cost that every retail trader pays. Understand it well and you'll control one of the biggest invisible drains on small accounts.

What exactly is the spread?

The spread is the difference between the bid price and the ask price for a currency pair. The bid is the price the market (or your broker) will pay to buy the base currency from you. The ask (sometimes called the offer) is the price you must pay to buy the base currency. The spread is measured in pips — the smallest standard price move for most currency pairs.

Example: EUR/USD shows a bid of 1.08500 and an ask of 1.08510. The spread is 0.00010 or 1 pip.

Quick definitions

Pip: the usual smallest price increment. For most pairs it's 0.0001. For JPY pairs it's 0.01.
Lot sizes: standard = 100,000 units; mini = 10,000 units (0.1 lots); micro = 1,000 units (0.01 lots).
Pip value (EUR/USD example): standard lot ≈ $10/pip; mini ≈ $1/pip; micro ≈ $0.10/pip. Pip values change slightly when the account currency is not USD.

How the spread becomes a cost — worked examples

When you open a market buy, you enter at the ask. Immediately after entry the market's bid is lower by the spread, so your position is already "in the red" by the spread amount. To get back to breakeven the market must move in your favour by at least the spread.

Example 1 — cost in pips and dollars

Pair: EUR/USD. Spread: 1 pip. Size: 0.1 lot (mini = 10,000 units). Pip value at this size: $1/pip.

Spread cost = 1 pip × $1 = $1. So your trade starts $1 below breakeven.

Example 2 — standard lot and commission

Pair: EUR/USD. Spread: 0.8 pips. Size: 1.0 lot (standard = 100,000 units). Pip value: $10/pip.

Spread cost = 0.8 × $10 = $8.
If your broker also charges $7 round-turn commission per lot, total round-turn cost = $8 + $7 = $15.

Note: some brokers quote "raw" spreads and add commission; others embed costs by widening the spread. Always calculate spread + commission as the true trade cost.

Fixed vs variable spreads — the difference

There are two common pricing models:

Fixed spreads: The broker advertises a constant spread (eg. 2 pips on EUR/USD). These are typical of market-maker brokers. Fixed spreads can be predictable in calm markets, but brokers can and do widen spreads behind the scenes in extreme volatility or restrict orders. Fixed spreads often come with no explicit commission.
Variable (floating) spreads: Spreads change with market liquidity and volatility. During the London/New York overlap, spreads on major pairs often tighten to 0.0–0.5 pips on ECN/STP pricing. At news releases or thin sessions, spreads widen. Many ECN/STP brokers charge a small commission but offer far tighter average spreads.

Which is better? It depends on your strategy. Scalpers often prefer raw variable spreads + commission for consistently low cost when the market is liquid. Longer-term traders may not notice spread differences as much, but wide spreads still increase required move to profitability.

How spreads affect profitability and break‑even calculations

Every trade must first recover the spread before producing a net profit. A simple break-even pip calculation:

Breakeven pips = spread (in pips) + expected slippage (pips)

If you add broker commission, convert it into pip-equivalent by dividing total round-turn cost by pip value for your lot size.

Worked break-even example

Account size: $1,000. Risk per trade: 1% = $10. Trading EUR/USD with a 20-pip stop-loss.

Lot size selection: pip value for 0.01 lots (micro) = $0.10/pip, 0.1 lots (mini) = $1/pip. Using the position-sizing formula:

Position size (lots) = Risk amount ÷ (stop-loss pips × pip value per lot)

If we aim to risk $10 with a 20-pip stop and use mini-lots (0.1): pip value = $1/pip → position = $10 ÷ (20 × $1) = 0.05 lots (half a mini)

Assume spread = 1 pip. Spread cost in pip-equivalent at 0.05 lots: pip value = $0.05/pip → cost = 1 × $0.05 = $0.05. That's small on this tiny position, but if you scaled to larger sizes the spread becomes material.

Practical tips to minimise spread-related expenses

These steps lower the impact of spread on small accounts and recurring costs over many trades.

Trade major pairs when possible. EUR/USD, USD/JPY, GBP/USD typically have the tightest spreads. Exotic pairs often carry several times wider spreads.
Trade during the most liquid hours. The London and New York overlap usually offers the lowest spreads. See the session guidance in our currency pairs explainer: Currency Pairs Explained: Majors, Minors & Exotics 2026.
Use limit orders when you're not racing the market. A limit buy placed at or just below the current bid can sometimes avoid paying the full ask; you may get filled at better price than a market order. This is especially useful for planned entries.
Avoid trading right before and after major news releases. Spreads can widen dramatically around high-impact economic data; the widening can blow out short-term strategies.
Compare overall trading costs, not just headline spreads. Add spread + round-turn commission to compute a like-for-like cost. For guidance on broker selection, read: How to Choose a Forex Broker in 2026: Step‑by‑Step Guide.
Match your strategy to pricing model. If you scalpe, a raw ECN model with commission and variable tight spreads often wins. If you make few longer-term trades, an inclusive fixed-spread account might be acceptable.
Control position size. Spreads scale with lot size. Smaller lots reduce absolute spread cost in dollars, helpful when preserving a small demo or live starter account.

How to test spread impact on your strategy

Before risking real capital, run your strategy on a demo account and measure how many trades were negatively affected by wide spreads. You can also use Monte Carlo or expectancy tests to see how different average spreads change your edge. Our Monte Carlo lesson covers that in depth: Monte Carlo Simulation Forex: Test Strategy Robustness 2026.

Where to practice these ideas

Open a free demo account and try entries, limit orders and session timing so you can see spreads in real time. We recommend practising on demo before live trading; you can open a free demo account with our partner broker here: open a free Exness demo account.

Platform settings and order types

Learn the basics of your trading platform so you can use limit, stop and pending orders correctly. The common platforms MT4/MT5 have built-in order types and execution modes — read our beginner-friendly guide for a quick walkthrough: MT4/MT5 Platform Operation Guide 2026 — Beginners and How MetaTrader Works in 2026 — MT4 & MT5 Explained.

When low spreads still cost you: slippage and execution

Even with low advertised spreads you can suffer slippage — the difference between the quoted price and the price at which your order fills — during fast moves. That's a separate but related cost to consider. The cure is good execution: use a reliable broker, test execution on demo, and avoid aggressive market orders during illiquid times.

Summary — key takeaways

The spread is the bid‑ask difference and is an immediate, unavoidable cost when you enter a trade.
Calculate spread cost in dollars: spread (pips) × pip value × lot size. Add commission to get true round‑turn cost.
Variable spreads usually give lower average cost during liquid sessions; fixed spreads are predictable but can widen in stress.
To reduce spread costs: trade majors, use liquid sessions, use limit orders where practical, control position size, and compare total costs across brokers.

Frequently Asked Questions

What is spread in forex?

The spread is the difference between the bid price and the ask price for a currency pair. It's measured in pips and represents an immediate cost you must overcome before a trade becomes profitable.

How do fixed and variable spreads differ?

Fixed spreads stay the same in normal conditions and are commonly offered by market-makers. Variable (floating) spreads change with market liquidity and volatility and are typical of ECN/STP pricing; they can be tighter in liquid hours and wider at news times.

How do I calculate spread cost in dollars?

Multiply the spread (in pips) by the pip value for your lot size. Example: 1 pip × $10/pip (standard lot) = $10 cost. Add any round‑turn commission to get the full trade cost.

Do spreads matter for long-term traders?

Yes. Although spreads matter most for scalpers and frequent traders, wide spreads increase the move needed to break even and reduce net profit even on longer-term trades, so they should be considered in trade planning.

Can I avoid paying the spread?

You cannot avoid the spread entirely, but you can reduce its impact by using limit orders, trading liquid pairs during active sessions, and selecting a pricing model (commission + raw spread) that suits your strategy.

Should I open a demo account to test spreads?

Yes. Use a free demo account to see real-time spreads, test order types, and measure how spreads affect your system. We recommend practising on demo before risking real funds: open a free Exness demo account.

How do I choose a broker based on spreads?

Compare the combined cost: average spread + round-turn commission, execution quality, uptime and platform features. For a step-by-step selection guide, see: https://forexfluency.com/blog/how-to-choose-a-forex-broker-in-2026-step-by-step-guide.

What is a reasonable spread for EUR/USD in 2026?

In normal, liquid market conditions, tight ECN/STP pricing can show EUR/USD spreads around 0–1 pip. Many retail brokers advertise spreads between 0.1 and 1 pip during liquid hours, but spreads widen in volatility. Always check live quotes.
