PropFirmMath started with a simple frustration: prop firm rules are written as percentages and marketing, but accounts are lost in dollars and decimals. This site converts every important rule, payout structure and risk decision into a formula you can check in seconds.
Every calculator here is maintained by a working developer who builds trading automation (MT4/MT5 Expert Advisors) for clients daily. The same math that keeps client accounts inside their drawdown limits powers these tools.
We are independent: no prop firm pays for placement here. When we recommend a service or offer our own development services, it is marked as such. See our affiliate disclosure.
Editorial standards
Every number on this site is either a documented industry standard or an exact formula you can re-derive from the calculator itself. We do not publish earnings claims, and nothing here is financial advice.
We build and repair trading robots (MT4/MT5, MQL5) for a fixed price on Fiverr: view our MQL5 development services.
