How this is calculated
The spread is the built-in cost of entering a forex trade: you buy at the ask and immediately hold a position worth the bid, and that gap is a cost you pay before the trade has moved at all.
Spread cost in USD equals the pip value of your position multiplied by the spread in pips. Pip value uses the same convention as our pip value calculator: pip size times units directly when USD is the quote currency, or pip size times units divided by the exchange rate when USD is the base currency.
Pip size is 0.0001 for most pairs and 0.01 for JPY-quoted pairs like USD/JPY, matching standard forex convention.
This spread cost is a one-way cost paid on entry. Some brokers charge it once as the quoted spread, others also add a separate commission per side, check your own broker's fee schedule for the full round-trip cost.
If you enter trades per day, the daily/weekly/monthly figures simply multiply the single-trade spread cost by trade count, assuming every trade is the same size and pair.
Risk & liability disclaimer: This calculator produces a mathematical estimate based on the numbers you enter, not live market data or your actual broker's quoted spread. Spreads move continuously and can widen significantly around news events or low-liquidity periods; this tool does not pull or refresh spread data automatically. Actual costs vary by broker, account type, and market conditions, always confirm your broker's specific spread and commission structure.
