What is the excess margin ratio?

The excess margin ratio is a financial metric that measures the amount of capital a company has beyond its minimum required margin levels, often used in the context of margin trading and risk management. It is calculated by taking the difference between total equity and the required margin, divided by total equity. This ratio helps investors assess the safety and risk associated with their investments, indicating how much cushion exists before reaching a margin call. A higher excess margin ratio suggests a stronger financial position and lower risk.
