APR calculation

The APR (Annual Percentage Rate) is the potential annual yield generated by staking sdTOKENs into their gauge.

Current APR

When rewards are harvested, they are distributed over 7 days to users who have staked their sdTOKENs in the gauge.

The gauge updates the rate and the period_finish properties returned by the reward_data view, and it means that the reward token will be distributed at this rate per second until the period_finish.

Based on this rate and the price of the reward token, Stake DAO can then compute the APR of a user using his working_balance (a boosted balance based on the users' veSDT position).

The current APR is then the following :

After computing this APR, Stake DAO deducts fees and displays the APR net of fees.
