Forex cost calculator: the all-in cost of a trade
Spread plus commission, per trade and per month, across the brokers we review. Figures start from each broker's published headline pricing, and you can overwrite them with the spreads you actually see.
| Broker and account | Spread (pips) | Commission per side, per lot ($) | Cost per trade | Cost per month |
|---|
Cost per trade = lots × spread × pip value + commission on both sides. Interactive Brokers charges at least $2 per order, which the calculator applies. Excludes swaps, conversion and non-trading fees. Headline "from" spreads are minimums; your average spread will be higher, especially around news and outside the London and New York sessions. Replace them with figures from a demo account for a fair comparison.
Forex cost calculator by Forex Awards. Figures from our broker reviews.
How to use the result
- Compare like with like: a raw account (low spread plus commission) against a standard account (wider spread, no commission).
- Use average spreads from a demo account at the hours you trade, not the headline minimum.
- Add swap costs if you hold trades overnight; see swap rates explained.
- See how costs change with trade size in our trading costs study.
- Then check the company that would hold your account on our comparison page.
Figures come from our reviews and each broker's own pricing pages and can change. Forex and CFDs are leveraged and most retail accounts lose money. General information, not financial advice.
