What Spread Is and Why Every Trade Starts in the Red
The spread is the difference between the bid price (the price at which you can sell a currency pair) and the ask price (the price at which you can buy it). When you place a trade in forex, you always buy at the ask and sell at the bid. The moment your order is filled, your position shows an unrealized loss equal to the spread — because you would need the market to move in your favor by at least the spread amount before breaking even.
A practical example: EUR/USD is quoted at 1.10500/1.10508. The spread = 0.8 pips (ask 1.10508 minus bid 1.10500). You open a long trade at the ask: 1.10508. Your position immediately shows a bid price of 1.10500 — the only price at which you can currently close. You are instantly in an −0.8 pip unrealized loss. For EUR/USD to reach your break-even point, the bid price must rise to 1.10508, meaning the overall pair must move 0.8 pips in your favor.
Spread is the most universal trading cost in forex — all traders pay it regardless of broker type, account size, or trading frequency. Unlike commission (which some brokers charge and others do not) or overnight swap (only for positions held past rollover), spread is embedded in every single trade from the moment of entry. Understanding it lets you accurately calculate true profitability after costs using the profit and loss calculator.
Spread Cost in Dollars: Calculations for Every Lot Size
Spread cost in dollars = Spread pips × Pip value × Lots. For EUR/USD with a 1.0 pip spread: Standard lot = 1.0 × $10 × 1 = $10 spread cost per trade (round-trip: you pay on entry, not on exit). Mini lot = $1. Micro lot = $0.10. A trader placing 20 micro-lot trades per month with a 1-pip spread pays 20 × $0.10 = $2 in spread per month — negligible. The same strategy at 20 standard-lot trades = $200/month in spread costs before any other fees.
For pairs with higher pip values, spread costs are proportionally larger. GBP/USD with a 1.5-pip spread on a standard lot: 1.5 × $10 × 1 = $15 per trade. USD/JPY with a 1.5-pip spread at $6.67/pip: 1.5 × $6.67 = $10 per trade. Exotic pairs present the starkest spread impact: USD/ZAR with a 30-pip spread and very low pip value ($0.30/pip standard lot) = $9 per standard lot — not obviously large, but the spread represents 30 pips of required favorable movement before any profit is generated.
The total trading cost calculation that every trader should run for their strategy: (Spread cost + Commission) × Trades per Month = Monthly overhead. If your strategy averages 40 pips profit per trade with 1% win rate and $10 spread + $7 commission per standard lot, your break-even pip target per trade including costs is 40 + (17/10) = 41.7 pips. Verify this is still above your minimum R:R threshold after incorporating costs — see the risk/reward guide for the full profitability equation.

There are two main broker pricing models. Market makers (also called dealing-desk brokers) offer fixed or slightly variable spreads with no separate commission. EUR/USD typical spread: 1.0–1.5 pips, all-in cost. ECN/STP brokers offer raw interbank spreads (often 0.0–0.3 pips on EUR/USD) plus a fixed commission per lot — typically $5–7 per standard lot round trip. The right choice depends on your trade size and frequency.
Cost comparison for EUR/USD standard lot at different trade targets: 20-pip scalp trade, market maker (1.5-pip spread = $15 cost): net gain on 20-pip target = $200 − $15 = $185. ECN (0.2-pip spread + $6 commission = $8 total cost): net gain = $200 − $8 = $192. ECN saves $7. Same comparison on a 5-pip scalp: market maker = $50 − $15 = $35 (30% cost). ECN = $50 − $8 = $42 (16% cost). ECN advantages grow with tighter targets.
For traders with targets above 50 pips, the difference between a 1-pip market maker and an ECN with a 0.3-pip spread plus $6 commission is almost irrelevant — both represent well under 5% of gross profit on the trade. Where the choice matters most is for scalpers and traders with small targets. High-frequency traders (20+ trades/day) at standard lot size should always model their monthly spread + commission costs across both broker types before selecting.
How to What Is Spread? — Step by Step
- 1
Identify the bid and ask price
The bid is the price at which you sell (lower). The ask is the price at which you buy (higher). The spread = Ask − Bid. If EUR/USD bid = 1.10500 and ask = 1.10508, the spread is 0.8 pips.
- 2
Convert spread to a dollar cost
Spread cost = Spread in pips × Pip value × Lots. A 1-pip spread on 1 standard lot EUR/USD = $10. On a mini lot: $1. On a micro lot: $0.10.
- 3
Add spread to your break-even calculation
Your trade must overcome the spread before showing any profit. A 30-pip target with a 1-pip spread means your effective target is 29 pips of clean gain after covering the spread cost.
- 4
Compare spreads when choosing a broker
ECN brokers typically offer raw spreads of 0.0–0.3 pips on EUR/USD but charge a fixed commission ($5–7 per standard lot). Market maker brokers offer 1.0–2.0 pip spreads with no commission. Calculate the total cost for your typical trade to determine which model is cheaper for your trading style.
Frequently Asked Questions
Q.What is the bid-ask spread in forex?
The bid-ask spread is the difference between the highest price a buyer will pay (bid) and the lowest price a seller will accept (ask). In forex, your broker quotes both prices simultaneously. When you open a buy (long) trade, you pay the ask. When you open a sell (short) trade, you receive the bid. The spread between them is the broker's immediate compensation — every new trade starts with an unrealized loss equal to the spread cost.
Q.How much does a 1-pip spread cost me?
On a standard lot (100,000 units) of EUR/USD: a 1-pip spread costs $10. Mini lot: $1. Micro lot: $0.10. The cost depends entirely on lot size and pip value for the specific pair. A 1-pip spread on GBP/USD (also $10/pip standard) costs the same as EUR/USD. A 1-pip spread on USD/JPY (≈$6.67/pip standard) costs less in dollar terms.
Q.What is a typical forex spread?
EUR/USD, the most traded pair, typically has spreads of 0.1–1.5 pips depending on broker type and market conditions. ECN brokers: 0.0–0.3 pips raw spread + commission. Standard market maker brokers: 1.0–2.0 pips all-in. GBP/USD typically runs 0.5–2.0 pips. Exotic pairs (USD/TRY, USD/ZAR) can have 10–50+ pip spreads. Spreads widen during major news events and when liquidity thins before the weekend close.
Q.Is spread charged when I open or close a trade?
The spread is paid on entry — the moment you open a position, you are immediately in a loss equal to the spread cost. There is no additional spread charged on closing a position (though you pay the current spread again if you use a market order to close). This is why a trade "starts negative" in your broker's P&L display. The position must first move in your direction enough to cover the spread before showing any realized profit.
Q.What is the difference between fixed and variable spreads?
Fixed spreads stay constant regardless of market conditions — you always pay the same spread. Variable (floating) spreads change with market liquidity and volatility. During major economic news releases, variable spreads can temporarily widen to 10× or more of their normal level. Fixed spreads are more predictable for cost calculation but are generally higher on average. Variable spreads are usually tighter in normal conditions but can create significant unexpected costs during volatility.
Q.How do I calculate whether a trade is worth taking after spread costs?
Net P&L at target = (Target pips − Spread pips) × Pip value × Lots. If your target is 20 pips with a 1.5-pip spread, your effective gain is 18.5 pips. At 0.5 lots EUR/USD ($5/pip): net gain = 18.5 × $5 = $92.50. Net loss at stop (no spread credit, spread still paid): Stop pips × Pip value × Lots. A 15-pip stop at 0.5 lots = $75 loss, plus $7.50 spread cost = $82.50 total loss. Use the [profit and loss calculator](/calculators/profit-loss-calculator) to include all costs accurately.
Q.Does spread matter for swing traders vs scalpers?
Spread impact is inversely proportional to trade duration and target size. A scalper targeting 5 pips who pays a 1-pip spread loses 20% of their gross profit to spread before commission. A swing trader targeting 150 pips who pays the same 1-pip spread loses less than 1%. Spreads are critical for scalpers and day traders with small targets but nearly irrelevant for swing or position traders with wide targets. Choose your broker's spread model based on your actual trading style and target sizes.
