Spread Cost Calculator

Money cost of the spread for a trade.

Calculator

The spread cost calculator shows what the spread costs you in money on a trade. The spread is the gap between the bid and ask price, and you pay it on every trade you place. Enter the spread in pips and your trade size to see the cost in your account currency, both in total and per standard lot.

How to Use the Spread Cost Calculator

  1. Choose the Instrument and your Account currency.
  2. Enter the Spread (pips) shown on your trading platform.
  3. Enter the Trade size (lots).
  4. Leave Quote→acct rate blank to convert at the live rate, or type your own.
  5. Press Calculate.

Spread Cost Formula

Spread cost = spread in pips × pip size × contract size × quote-to-account rate × lots

  • Pip size is 0.0001 for most pairs, 0.01 for yen pairs and silver, 0.10 for gold and 1 for bitcoin.
  • Contract size is 100,000 units per lot for currency pairs, 100 ounces for gold, 5,000 ounces for silver and 1 coin for bitcoin.
  • Quote-to-account rate converts the pair's quote currency into your account currency. It is 1 when they match.
  • Lots is your trade size. Together, the first three terms give the pip value per lot.

Worked Example

You trade 2 lots of EUR/USD on a USD account, and the spread is 1.2 pips.

  • Pip value per lot: 0.0001 × 100,000 × 1 = 10 USD
  • Cost per standard lot: 1.2 × 10 = 12.00 USD
  • Spread cost: 12.00 × 2 = 24.00 USD

Over 50 trades of the same size, that adds up to 1,200.00 USD. On gold, a 0.30 spread is 3 pips, so 1 lot costs 3 × 0.10 × 100 = 30.00 USD.

How Traders Use the Result

Compare the spread cost with your usual profit target. If you aim for 10 pips and pay 1.2, the spread takes 12% of each winner, which is why scalpers look for the tightest pricing. Spreads vary by broker, account type and time of day, so treat the figure as indicative.

FAQ

Why does the spread matter?

You start every trade down by the spread, so price has to move that far in your favour before you break even. Tight spreads matter most for scalpers and frequent traders, because the cost repeats on every trade.

Do I pay the spread when I open and again when I close?

You pay it once per trade. You buy at the higher ask and sell at the lower bid, so across the round trip you cross the gap one time. The calculator shows that one-off cost for the size you enter.

Does the spread cost include commission?

No. It covers the spread only. Raw-spread accounts usually charge a commission per lot as well, so add that on top when you compare total trading costs. Overnight swap is a separate charge too.

How do I enter a gold spread in pips?

This calculator counts one gold pip as 0.10. A spread of 0.30 on gold is 3 pips, and a spread of 0.25 is 2.5 pips. If your platform shows gold spreads in points of 0.01, divide the points by 10.

Why does the spread change during the day?

Spreads follow liquidity. They are usually tightest when the major sessions overlap and widest around the daily rollover, the weekly open and big news releases. The live figure on your own platform is the one to use.
