What Is the Difference between the Premium Index and the Funding Rate?

The Premium Index is a component used to calculate the Funding Rate. It measures the difference between the perpetual contract's Mark Price and the Index Price.

The Funding Rate is the final calculated percentage that is applied to a trader's position, and it incorporates the Premium Index along with an Interest Rate Component. Essentially, the Premium Index is the raw price deviation, while the Funding Rate is the actionable fee/payment percentage.
