Retaining Wall Cost Calculator
A retaining wall cost calculator estimates the price of a retaining wall by multiplying the wall face area (length times height) by your price per square foot of wall face. Block, stone, concrete and timber walls each cost differently. Enter your wall length, height and price per square foot below for an estimate.

How Much Does a Retaining Wall Cost?
A retaining wall costs its face area (length times height) times your price per square foot of wall face. Material drives the range: interlocking concrete block is mid-range, natural stone costs more, and engineered walls for height add reinforcement and cost. The base, drainage gravel and backfill are essential and add to the total. The calculator estimates the wall face from your price; budget separately for base and drainage.
Why Is Retaining Wall Cost per Face Foot?
Retaining wall cost is measured per square foot of wall face because the visible wall area (length times height) captures both how long and how tall the wall is, which together drive material and labor. A taller wall of the same length costs more, and face-area pricing reflects that. The calculator uses face area times your price, and remember that walls over about 3 to 4 feet often need engineering, which adds cost.
