Introduction to Funding Rates
Funding rate is a critical mechanism in perpetual swap markets that balances long and short positions while maintaining price stability. This guide explains the calculation methodology with practical examples and analyzes key factors influencing funding rates—from market dynamics to exchange policies.
Understanding Funding Rates
Definition and Purpose
Funding rate is a periodic payment exchanged between long and short position holders to align perpetual contract prices with spot market values. In markets without expiration dates, this mechanism prevents prolonged price deviations.
Key characteristics:
- Positive rate: Long positions pay shorts
- Negative rate: Short positions pay longs

Calculating Funding Rates
The standard formula incorporates two components:
Funding Rate = (Premium Index + Interest Rate Adjustment) × Scaling FactorComponents explained:
- Premium Index: Measures price divergence between perpetual and spot markets
- Interest Rate: Typically 0.01%-0.03% (varies by exchange)
- Scaling Factor: Exchange-determined parameter for market stability
