# Rate of Reward & APY
**Rate of Reward**
The reward rate to stakers is the percentage increase in sMARQ in the next epoch. The reward rate can be calculated below:
Where is the reward rate in the current epoch,is the total amount of MARQ allocated to stakers is the total amount of sMARQ from the last epoch.
**Annual Percentage Yield**
The annual reward rate for MARQ stakers compounded 3 times a day. Hence, the total number of epochs used to compound the return is 365\*3=1095, and the APY can be calculated below:
The power of compounding will increase the value of stakers’ assets exponentially.
**MARQ Supply per Epoch**
The protocol distributes part of newly minted MARQ to stakers, denote by, which is calculated according to the following equation:
where is the residual of total MARQ supply, is the reward ratio which is determined by the protocol and DAO governance.
