# Lending & Interest Rate Model

Single Finance adopts a triple-slope interest rate model to determine borrowing interest rates. Different assets shall employ different parameters of the same model.

#### *Borrowing Interest = Multiplier \* Utilization + Base Rate*

***Lending Interest = Borrowing Interest \* Utilization \* (1 - Lending Reserve Fee)***
