Four calculators for the arithmetic that comes up around a trade. They run in your browser and nothing is sent anywhere.

Margin calculator	What a position ties up, from a size, a price and a leverage
Commission calculator	What a trade costs on a Pro or a Standard account
Margin call and stop out calculator	Your margin level, and the equity at which the 80% call and 50% stop out are hit
IB rebate calculator	What a month of referred client volume pays an Introducing Broker

None of them read your account. You type the figures in, which means you can model a position you have not opened, or one on an account you do not hold. It also means the results are only as good as what you enter.

For the real numbers on a real position, the platform is the authority. It shows the margin on the order ticket before you confirm, and your trade history shows what a closed deal actually cost.

Where the underlying figures live

• Symbol Specifications has contract sizes, lot limits and the leverage bands per instrument group.
• Fees & Commissions has the commission schedule these calculations are built from.
• IB Program has the rebate rate card, the tier thresholds, and the dashboard that holds your real earnings.
