What is the consistency rule, exactly?
Many prop firms won't pay out an account if one single trading day produced an outsized share of the total profit — even if the profit target was hit and every risk rule was respected. This is the "consistency rule," and it exists so a firm doesn't fund a trader whose result came from one lucky trade rather than a repeatable process.
The exact threshold, and whether a firm enforces it at all, varies by firm and changes over time — figures you'll see quoted anywhere from 20% to 50%. Always confirm the current number in your own firm's rulebook before relying on it; the presets above are illustrative starting points, not live data from any specific firm.
This calculator sums your profitable days, finds your single best day, and checks whether that day's share of the total sits at or below your threshold. If it doesn't, it tells you how much additional profit you'd need spread across other days to bring the ratio back into range.
