Why trading costs matter more than most beginners think
Every trade starts at a loss. You buy at the ask and sell at the bid, so the spread is paid the moment you enter. Many accounts also charge a commission per lot, and holding overnight adds a swap. This calculator adds them together and shows how many dollars gold must move just to get back to zero, and what share of your planned risk the costs eat.
Worked example
You trade 0.10 lot with a $0.30 spread and $7 commission per lot round turn. Spread cost = 0.30 × 0.10 × 100 = $3.00. Commission = 7 × 0.10 = $0.70. Total $3.70 per trade, so gold must move $0.37 in your favour before you make a cent. With a $5 stop you risk $50, and the costs are 7.4% of that 1R. Scalp with a $1.50 stop and the same costs become almost 25% of your risk. That is why the same strategy can win on a wide stop and lose on a tight one.
The formulas
- Spread cost = spread in $ × lots × 100. Commission = commission per lot × lots. Swap = swap per lot per night × lots × nights.
- Break-even move = total cost ÷ (lots × 100).
- Break-even win rate before costs = 1 ÷ (1 + reward ÷ risk). After costs, the win becomes reward − cost and the loss becomes risk + cost.

Frequently asked questions
How do I calculate the spread cost on gold?
Multiply the spread in dollars by the lot size and by 100 (ounces per lot). A $0.30 spread on 0.10 lot costs 0.30 × 0.10 × 100 = $3.
What is a break-even move?
The number of dollars gold must move in your favour just to cover the spread, commission and swap of a trade. Divide the total cost by (lots × 100).
Why do costs hurt scalpers most?
The cost per trade stays the same, but a scalper’s stop and target are small, so the same cost is a much bigger share of each trade’s risk and reward. Many trades a day multiply it again.
Does a wider stop reduce costs?
Not in dollars per trade at the same lot, but if you size by risk, a wider stop means a smaller lot, so the cost becomes a smaller share of your risk. Use the slider above to compare.
Where do I find my real spread and commission?
In the platform: the spread is the gap between bid and ask, commission is in your account terms or trade history, and swap is in the symbol’s Specification.
