The club ended the season four points clear of second-placed Leicester Tigers, finishing the campaign with a 23-14 win over Bath yesterday.
The team's director of rugby told Sky Sports News: "It is a big achievement as Saracens have always struggled for consistency. However, it's now our fourth consecutive semi-final and the first time that we have finished top at the end of a regular season.
"We have to give credit to Bath for they made it difficult for us but I am thrilled how well we have come back from last Sunday's defeat by Toulon."
Saracens will face Northampton Saints in the playoff semi-finals.
