In this article, you can find how the Annual Percentage Rate (APR) for staking PSP is estimated, whether you stake in the Basic Pool (sePSP1) or the Boosted Pool (sePSP2).

Because of the way the PSP2.0 system is designed, several factors may affect your individual APR and make it diverge from the APR estimations shown. To learn more about it, you can visit the Why does my APR not match the APR shown section.

All APR calculations are based on the data found in the ParaSwap Analytics Dashboard.

The general APR reflects the overall performance of PSP staking by considering all ParaSwap Revenue and the whole Total Value locked, without differentiating between pools. The formula used to calculate the General APR is:

Where:

Please note that your individual APR may vary depending on your ParaBoost Score and ParaBoost Share. You can learn more here.

The Boosted Pool APR is the estimated general APR sePSP2 stakers can obtain before applying ParaBoosts. It indicates the staking return evolution of the Boosted Pool for each epoch.

The projected APR is calculated to give an idea of the current epoch’s potential APR for Boosted Pool. It’s an estimation based on the revenue accrued so far during the current epoch and the median of the three previous epoch’s revenue, so it changes as the epoch progresses.

The Boosted pool current epoch projected APR is estimated by linearly projecting the total ParaSwap Revenue by the end of the ongoing epoch with the following formula:

Where:

Please note that your individual APR may vary depending on your ParaBoost Score and ParaBoost Share. Learn more here.

The Boosted pool previous epoch estimated APR shows the general APR boosted pool stakers got for the last epoch, and it’s calculated with the following formula:

The Basic Pool APR is the estimated general APR sePSP1 stakers can obtain before applying ParaBoosts.

The projected APR is calculated to give an idea of the current epoch’s potential APR for the Basic Pool. It’s an estimation based on the revenue accrued so far during the current epoch and the median of the three previous epoch’s revenue, so it changes as the epoch progresses.

The Basic pool current epoch projected APR is estimated by linearly projecting the total ParaSwap Revenue by the end of the ongoing epoch with the following formula:

The Basic pool previous epoch estimated APR shows the general APR basic pool stakers got for the last epoch, and it's calculated with the following formula:

The estimated General APR, Boosted Pool APR, and Basic Pool APR may differ from the final individual APR you got or will get for the following reasons:

PSP 2.0 is designed to incentivize PSP stakers who add value and perform services to ParaSwap through individual ParaBoosts.

General, Boosted Pool, and Basic Pool APRs estimations do not consider the effect of ParaBoosts as these are done per address and apply at an individual level.

Your final individual APR is influenced by your own ParaBoosts and other staker’s ParaBoosts.

ParaSwap epoch’s revenue is calculated by taking the USD value at the moment of accrual of the different tokens collected by ParaSwap as fees.

However, since the implementation of the ParaSwap Fee Collector by Mimic, ParaSwap fees are converted automatically and asynchronously to wETH for their distribution.

Fee token and wETH price variation between the accrual moment and the moment they are swapped to wETH may impact the amount of wETH distributed by the end of the epoch, impacting the final individual APR.
