Interlocking concrete block is the affordable, popular choice; poured concrete is stronger for taller walls; natural stone is the premium look. Height matters a lot \u2014 taller walls need engineering, drainage and a deeper base.
How it’s calculated & sources
Cost = wall face area (length × height) × per-sq-ft rate for the material. Estimates are then scaled by a regional construction-cost factor for your area (U.S. average = 1.00).
Cost ranges from 2025–26 national home-improvement data (HomeAdvisor, Angi, Fixr and industry guides); regional factors approximate RS Means-style city cost indices. National average retaining wall \u2248 $33/sq ft of face \u2014 block $20\u201340, concrete $25\u201345, natural stone $30\u201350.
Results update as you type and are estimates, not a quote — site conditions, permits, and finishes move the final number. Verify with local pros.
Worked example
A 30-ft long, 4-ft tall block wall (120 sq ft of face) runs about $3,600 nationally (~$30/sq ft).
