Retaining Wall Costs. 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.
For simple interlocking blocks, the retaining wall cost would be approximately $15 to $30 per square foot. Therefore, for a 25-by-4-foot wall, the entire retaining wallâs cost would be anywhere from $1,500 to $3,000.
