## National default result

- **Typical:** $12,648
- **Planning range:** $8,221 to $20,237
- **Default quantity:** 160 sq ft of wall
- **Per unit:** $79 per sq ft of wall
- **Components:** materials $4,784, labor $6,874, permits $350, disposal $640

The national default is a planning estimate, not a contractor quote. A ZIP changes the labor component using a metro or state OEWS wage multiplier; it does not change materials.

## Inputs

- **Wall face area:** default 160 sq ft of wall
- **Material / quality:** default standard
- **Scope depth:** default standard

## Calculation

    material = baseline material rate × quantity × material index change × quality
    labor = baseline labor rate × quantity × labor index change × ZIP wage multiplier
    subtotal = material + labor + permit + disposal
    range = subtotal × documented low/high multipliers

Material index: WPUIP2300001, latest period 2026-07-01, change 6.78%.  
Labor index: CES2000000003, latest period 2026-07-01, change 2.29%.

## Main price drivers

- Wall height and face area
- Material and structural system
- Excavation and equipment access
- Drainage and backfill design
- Engineering, permits, and disposal

## Questions and direct answers

### What does this retaining wall cost include?

The estimate separates materials, labor, permit, and disposal using the quantities shown. It excludes financing, hidden damage, and optional work not selected.

### How does the ZIP adjustment work?

ZIP is matched to a metro when available; otherwise a state wage factor is used. Only labor changes. Materials remain tied to national price indices.

### Is this a contractor quote?

No. It is a planning estimate. Confirm scope, code requirements, and price with licensed local contractors before committing funds.

### Why is the range wider than the typical cost?

The low and high multipliers capture ordinary variation in finish level, access, site conditions, and contractor availability.

### How current is the estimate?

The baseline is dated 2026-01-01. Index observations and their latest periods are displayed with every result.

### Can I use the result for a budget?

Use it as an early planning range and include contingency. A site-specific quote remains necessary for a committed budget.
