# 이자율 모델

### 가동률(Utilization ratio)

$$
Utilization Ratio=(TotalBorrowed/PoolLiquidity)\*100
$$

​

### 예치  이율(Deposit  APR)

$$
DepositAPR=BorrowAPR∗(1−reserveFactor)
$$

* 플러스 예치, 롱/숏 포지션 예치자가 지불하는 누적 이자 수익의 80%는 단일 풀 예치자에게 분배되며, 20%는 Reserve fund로 분류되어 KSP 바이백과 소각에 사용합니다. 
* reserve Factor = 0.2

###

### 활용비용(Borrow APR)

$$
BorrowAPR=BorrowingRateModel\*Utilization
$$

\*MBX , AZIT 토큰의 경우,  다른 토큰의 이자율 모델과 상이하므로 참고해주시기 바랍니다.
