What is maintenance rate?
Maintenance rate shows how much collateral remains versus your debt after a price swing.
Formula: adjusted collateral ÷ loan amount × 100%.
Falling below the broker minimum may trigger margin calls or forced selling.
Use a conservative drop percentage to leave yourself a comfortable safety buffer.
