Understanding Leverage in Perpetual Contracts
Perpetual contracts offer various leverage options ranging from 1x to 100x. Key concepts include:
Nominal Leverage: The multiplier selected in your trading interface
- Determines maximum position size and required margin
- Actual Leverage: Real risk exposure based on position value versus margin
Leverage Calculation Methods
Isolated Margin Mode
- Actual leverage = Nominal leverage
Cross Margin Mode
- Full position: Actual leverage = Nominal leverage
- Partial position: Actual leverage differs from nominal leverage

Coin-Margined Contracts:
(Contract Quantity ร Face Value) / (Last Price ร Account Equity)
or
Position Coin Amount / Account Equity (USDT)
USDT-Margined Contracts:
(Contract Quantity ร Face Value ร Last Price) / Account Equity
or
(Position Coin Amount ร Last Price) / Account Equity
Example:
10x nominal leverage with 30% position size = 3x actual leverage
Funding Rate Mechanics
The funding rate comprises two components:
- 8-hour financing cost (borrowing interest)
- Premium (market sentiment indicator)
Key features:
- Collected every 8 hours
- Helps maintain price convergence with spot markets
- Uses moving averages for premium calculations
Exchange Implementation Differences
While core principles remain consistent, exchanges optimize:
- Premium calculation methods
- Rate adjustment frequencies
- Moving average periods
