Interest Rate (I)

The Interest Rate is calculated with the interest on the quote and base index as well as the funding interval.

Interest Rate Equation

$$ \textsf{Interest Rate (I)} = {\textsf{(Interest Quote Index - Interest Base Index)}\over\textsf{Funding Interval}} $$

For BTC/USDT Contracts:

\begin{align}&\scriptsize\textsf{*Interest Quote Index = USDT Interest Index}\\&\scriptsize\textsf{*Interest Base Index = BTC Interest Index}\\&\scriptsize\textsf{*Funding Interval = 3 (Every 8 hours, 3 times per 24 hours))}\end{align}
