Stubbs, 44, has become the Millers' new manager after signing a three-year deal after deciding to leave Hibernian just 10 days after winning the Scottish Cup.
The former Everton and Celtic defender said that as a career move Rotherham was too good to turn down and is setting his sights high for the 2016-17 campaign.
Stubbs, who replaced Neil Warnock in the Millers hotseat, said: "The club have had two seasons now where they have stabilised in the Championship and we are looking now to take the club forward. That's the aim, full stop.
"We want to be moving up the table and, ultimately, one that is around the play-offs come the end of the season.
