How to calculate your wall

  1. Enter your dimensions and select a block product or custom size.
  2. Expand 'Materials & budget options' to enter per-block and per-cap prices.
  3. Review the combined materials total and use CurveSet for more complete sitework takeoffs.

Worked example

For the 20-foot straight-wall example: 103 blocks at $4.50 and 15 caps at $7.50 yields a $576 estimated block-and-cap total, before other materials or job costs.

These are preliminary quantities, not a substitute for site measurements or product specifications.

Planning tip: This calculator includes only wall blocks and caps when both prices are entered. It does not invent labor, excavation, drainage, base, reinforcement, delivery, tax or permit costs.

Frequently asked question

Does this calculate the complete installed retaining wall price? No. It calculates a component of the materials budget and leaves site-dependent costs to your own estimates.
