The spread cost calculator shows the exact dollar cost of your broker's spread on any forex trade. The spread is the difference between the bid and ask price — you pay it every time you open a trade, and it is your broker's primary revenue. Most traders underestimate how much spread costs them over many trades. This calculator shows spread cost per trade, per day, per month, and per year based on your trading frequency, helping you understand the true impact of spread on your profitability and why choosing a tight-spread broker matters.
This free spread cost calculator works directly in your browser — no download, no registration, and no delay. All calculations are performed client-side, so your trading data is never transmitted to a server.
The formula used is: Spread Cost = Spread (pips) × Pip Value × Lot Size. This is the same formula used by professional traders and institutional risk managers worldwide.
Supported asset classes include: Forex, Crypto, Stocks. Each asset class applies the correct unit conventions so results are always accurate regardless of the market you are trading.
