The Lions are in the bottom quarter of the table on 55 points - four clear of trouble - but have four games left compared to the two that most of their rivals have.
Three of them are at The Den, including Tuesday night's meeting with Blackburn, and their manager is hoping that the lack of travelling can help his side.
Millwall's fixture pile-up comes on the back of their run to the FA Cup semi-finals and Jackett said: "From our point of view we still have four games left and the equation does lie with getting a team that has the energy to get the points we need at home."
The former Swansea and Watford boss, whose side lost 3-0 at Huddersfield at the weekend, added: "We have to lick our wounds, make sure we get it right and have a freshness and move on again.
"I'm obviously concerned, but we have to look forward and focus on our three home games in a row. We must get over it quickly."
Victory would leave Millwall safe on 58 points as third-bottom Wolves have 51 with two games left. However, the same can all but be said for Blackburn.
