Methodology
Every number in our calculators comes from the tables on this page. Each value lists its sources and the date we checked them. Where sources disagree, we use the range most of them share and note the outliers.
Installed costs are U.S. national averages for professional installation on a prepared, level site. Your local quote can differ with access, slope, drainage, permits and season. Regional multipliers shift the whole estimate; they are approximations, not ZIP-level pricing. Quantities include waste for cuts and breakage, and the base includes a compaction allowance.
Installed cost per square foot (patio / walkway, U.S. average)
Material-only cost per square foot (DIY)
Adjustments
Base, sand and joints
Laying pattern waste
| Pattern | Waste allowance |
|---|---|
| Running / stack bond | 5% (+5% for curved edges) |
| Basketweave | 7% (+5% for curved edges) |
| Random / ashlar | 10% (+5% for curved edges) |
| Herringbone (45°) | 15% (+5% for curved edges) |
