Cost Of Retaining Wall. The cost of a retaining wall depends on the material chosen, the overall height of the wall and the length of the wall. Wood retaining walls start at $15 per square foot, while concrete retaining walls start at $20 per square foot.
This can add a few thousand dollars to the job, depending on the length of the wall. Though experts generally recommend that retaining walls sit no higher than four feet without any additional support, it's possible to have a retaining wall of up to 10 feet high. These taller walls can cost nearly $20,000 while a six-foot-wall can cost around $13,000.
