# Interest Rate Model
## APY Function
**Borrow APY**
\= \[1 + Base + Multiplier \* min(UtilizationRate, Kink) + max(JumpMultiplier \* UtilizationRate - Kink, 0)] ^ 10512000 - 1
**Supply APY**
\= Distribute (Interest Paid by Borrowers Per Block - Reserve) to all suppliers, and convert it into APY
\= Distribute \[(1 + Borrow APY) ^ (1 / BlocksPerYear) - 1] \* Total Borrow \* (1 - Reserve Factor) to all suppliers, and convert it into APY
\= {\[(1 + Borrow APY) ^ (1 / BlocksPerYear) - 1] \* Total Borrow \* (1 - Reserve Factor) / Total Supply}, and convert it into APY
\= {1 + \[(1 + Borrow APY) ^ (1/BlocksPerYear) - 1] \* Total Borrow \* (1 - Reserve Factor) / Total Supply} ^ BlocksPerYear - 1
\= **{1+\[(1+Borrow APY)^(1/BlocksPerYear)-1]\*(1-Reserve Factor)\*Utilization Rate}^BlocksPerYear-1**
