Prop firm consistency calculator
Model the common best-day consistency shape: today's profit cannot dominate total profit past a set percentage. Firm formulas differ — check current firm rules.
Max today if today is your best day
$1,000
Extra profit needed to dilute an oversized best day
$0
Formula when today becomes the best day: max today = (limit% ÷ (100 − limit%)) × profit so far. Example at 40%: max today = (0.40 ÷ 0.60) × prior. Firm definitions differ — check current firm rules.
