What Is the Formula for Calculating Margin Ratio?

The margin ratio is typically calculated as (Equity / Maintenance Margin Requirement) x 100%. Equity is the account balance plus unrealized P&L. If the ratio falls below 100%, the account is below the maintenance margin, triggering a margin call or liquidation.

Some exchanges use (Margin Balance / Position Value) for calculation.
