Retaining Wall Costs Calculator

Retaining walls serve as essential structural elements in landscaping and construction projects, providing support to soil and preventing erosion. The cost of building a retaining wall can vary significantly based on factors like length, height, and the materials used. To help you determine the estimated cost, we’ve created the Retaining Wall Costs Calculator.


To calculate the retaining wall cost, we use the following formula:

Total Cost = Length (in feet) × Height (in feet) × (Material Cost per Square Foot + Labor Cost per Square Foot)

How to Use

  1. Enter the length of the wall in feet.
  2. Input the height of the wall in feet.
  3. Specify the material cost per square foot in dollars.
  4. Enter the labor cost per square foot in dollars.
  5. Click the “Calculate” button to get an estimate.


Suppose you have a retaining wall that is 20 feet long, 5 feet high, with a material cost of $10 per square foot and a labor cost of $5 per square foot. Using the calculator:

  • Length: 20 feet
  • Height: 5 feet
  • Material Cost: $10 per square foot
  • Labor Cost: $5 per square foot

After clicking “Calculate,” you will receive the estimated retaining wall cost.
