How to Calculate Spread Cost in Forex

The spread is the difference between the bid and the ask price on a forex pair, and it represents the first cost you pay on every trade. Converting that spread from pips into account-currency terms is a basic but useful skill, both for understanding the cost of a single trade and for comparing trading costs across instruments, account types, and brokers.

This guide covers what the spread is in forex, how to calculate the spread cost on a trade using a clear formula and worked examples, how spread costs compare across the four TIOmarkets account types, and the practical considerations involved.

What Is the Spread in Forex?

The spread is the difference between the bid price (the price at which the market will buy from you) and the ask price (the price at which the market will sell to you). The ask is always higher than the bid; the gap between them is the spread, expressed in pips.

The spread represents the transaction cost of opening and immediately closing a position at market. If you buy at the ask and the price does not move, the bid (your sell price) is still below the ask by the spread amount. You start any new trade slightly behind, and the trade needs to overcome the spread before it becomes profitable.

Spreads are variable and are typically higher than minimum figures shown. They widen during low-liquidity periods such as overnight in the off-session and around high-impact news events. A pair that shows a 1.0 pip spread in the London session might show 2.5 pips or wider in the Asian off-hours.

How to Calculate Spread Cost

The spread cost on a single trade is calculated using the following formula:

Spread cost = Spread in pips × Pip value per lot in account currency × Number of lots

The pip value per lot depends on the pair and your account currency. For USD-quoted pairs on a USD account, the pip value on a standard lot is USD 10. For JPY-quoted pairs, the pip value is JPY 1,000 per standard lot, which needs to be converted to your account currency at the current USD/JPY rate (or the relevant conversion rate). For accounts in other currencies, similar conversions apply.

For accounts in currencies other than USD, the TIOmarkets Pip Value Calculator returns the pip value for any pair in your account currency at current rates, removing the need to do the conversion manually.

Worked Example (Standard Lot EURUSD, USD Account)

Assume the following:

• Pair: EURUSD
• Account currency: USD
• Position: 1.0 standard lot
• Bid: 1.09000
• Ask: 1.09015

Step 1: Calculate the spread. Ask minus bid is 1.09015 minus 1.09000, which equals 0.00015. On a 5-digit pair, this is 1.5 pips (or 15 points).

Step 2: Calculate the spread cost. Pip value on EURUSD for a USD account is USD 10 per pip per standard lot.

Spread cost = 1.5 pips × USD 10 × 1.0 lots = USD 15.

So a 1.0 lot EURUSD trade at this spread costs USD 15 to open and close at market.

Worked Example (JPY Pair)

Assume the following:

• Pair: USDJPY
• Account currency: USD
• Position: 1.0 standard lot
• Bid: 150.050
• Ask: 150.080
• Current USDJPY rate for pip value conversion: 150.000

Step 1: Calculate the spread. Ask minus bid is 150.080 minus 150.050, which equals 0.030. On a 3-digit JPY pair, this is 3.0 pips (or 30 points).

Step 2: Calculate the pip value. For JPY-quoted pairs, the pip value per standard lot is JPY 1,000. Convert to USD by dividing by the USDJPY rate: JPY 1,000 / 150.000 = USD 6.67 per pip per standard lot.

Step 3: Calculate the spread cost.

Spread cost = 3.0 pips × USD 6.67 × 1.0 lots = USD 20.00.

So a 1.0 lot USDJPY trade at this spread costs approximately USD 20 to open and close at market.

For smaller lot sizes, scale linearly. A 0.1 lot trade costs one tenth the spread amount, and a 0.01 lot trade costs one hundredth.

Spread Cost Across TIOmarkets Account Types

TIOmarkets offers four account types with different combinations of spread minimum and commission. Combining the two gives the total trading cost per round turn.

On the Standard account, minimum spreads start from 1.1 pips and there is no commission on forex. For a 1.0 lot EURUSD trade at the minimum spread, the cost is 1.1 pips × USD 10 per pip × 1.0 lots = USD 11. Spreads can be higher in live conditions.

On the Raw account, minimum spreads start from 0.0 pips, with a commission of USD 6 per round turn lot. For a 1.0 lot EURUSD trade at the minimum spread, the spread cost is 0.0 × USD 10 = USD 0, plus USD 6 commission, total USD 6.

On the VIP Black account, minimum spreads start from 0.3 pips with no commission. For a 1.0 lot EURUSD trade at the minimum, the cost is 0.3 pips × USD 10 × 1.0 = USD 3.

The Nano account is MT5 only and supports lot sizes from 0.001. Minimum spreads start from 0.6 pips, with a commission of USD 6 per round turn lot. For a 1.0 lot EURUSD trade at the minimum spread, the spread cost is 0.6 × USD 10 = USD 6, plus USD 6 commission, total USD 12.

The minimum figures above are starting points only. Spreads are variable and are typically higher than minimum figures shown.

Practical Considerations

Spread cost scales linearly with lot size. A 0.5 lot trade costs half what a 1.0 lot trade costs at the same spread; a 2.0 lot trade costs double. This makes spread cost simple to estimate once you know the pip value and the spread.

Spread cost also scales with the number of trades. A scalping strategy that opens and closes many trades per day accumulates spread cost quickly. A swing trading strategy holding fewer trades for longer pays the spread cost less often but pays it the same way per trade.

For frequently traded pairs and for traders running high volumes, the lower spreads on Raw and VIP Black accounts can reduce trading cost meaningfully compared with the Standard account, even after accounting for Raw's USD 6 commission. The break-even point depends on the typical spread you experience and your trading volume.

Commission on the Raw account, and on the Nano account, is charged in full when the position is opened and covers both the open and close of the trade.

Spreads widen during the off-session and around high-impact news events. If your strategy depends on tight spreads, the timing of your trades matters as much as the choice of account type. The Asian off-hours and the few minutes around major releases such as central bank decisions or US employment data are when spreads typically widen most.
