PROP FIRM CALCULATORS

Firm-specific calculators for risk, drawdown recovery, break-even, margin, swap costs, and position sizing. Open any calculator with FTMO, TopStep, Apex, and other rule sets preloaded.

How to use this hub

Start with the calculator that matches the decision you are actually making: sizing a trade, checking break-even economics, or seeing whether recovery is still realistic.

Then open it with the firm you trade or plan to buy. The point is not generic math. It is to see the math inside a real rule set.

What the calculators do not replace

A calculator can frame the risk, but it cannot guarantee discipline, fills, or strategy quality. Use the outputs as boundaries, not as permission to take maximum size.

Always confirm the firm's latest written rules before acting, especially if you are trading a trailing drawdown model or a recently changed payout workflow.
