How It Works
Margin Call Price = Loan Amount / (Shares x (1 - Maintenance Margin %))
Current Margin % = (Position Value - Loan) / Position Value x 100
Margin Excess = Current Equity - (Maintenance % x Position Value)
A margin call occurs when your equity falls below the maintenance margin requirement. Your broker will require you to deposit additional funds or sell securities to bring the account back above the maintenance threshold.
