The Spread Cost Calculator reveals the hidden cost of trading by calculating exactly how much you pay your broker in bid-ask spread for every trade you open. The spread is the difference between the buying price (ask) and selling price (bid) of a currency pair, and this difference represents the broker's profit or fee.
Understanding spread costs is critical for evaluating broker competitiveness and strategy profitability. For high-frequency traders and scalpers, spread costs can be the difference between profit and loss. A seemingly small 2-pip spread becomes a significant expense when trading multiple times per day.
Spread Cost = Spread (in pips) × Pip Value × Lot Size
Where:
For a standard lot (100,000 units) of EUR/USD, one pip equals $10. If the spread is 1.5 pips, your immediate cost is $15 per trade.
Example 1: Standard EUR/USD Trade
Calculation:
Spread Cost = 1.5 pips × $10 = $15 USD
You start every trade -$15. To break even, the price must move 1.5 pips in your favor.
Example 2: Scalper Trading 10 Times Daily
Calculation:
Cost per Trade = 2.0 × $5 (0.5 lot pip value) = $10
Daily Cost = $10 × 10 trades = $100 USD
Monthly Cost (20 trading days) = $100 × 20 = $2,000 USD
A scalper with a $10,000 account pays 20% of their capital annually just in spreads. This highlights why scalpers need ultra-tight spreads.
Example 3: Broker Comparison

Broker B (ECN):
Winner: Broker B is 60% cheaper despite having a "commission." This demonstrates why you must calculate total costs, not just compare spreads.
