Methodology

How we price.

Our estimates are illustrative 2026 ranges — not quotes. Here's exactly how they're built, so you know what you're looking at.

1

National baselines

Each project starts from a mid-range national cost band built from current contractor and materials data.

2

State cost index

We adjust every number by a state cost-of-construction index — labor and materials vary widely by region.

3

Tier & size multipliers

Budget, mid-range and high-end finishes, plus project size, scale the baseline up or down.

4

Human review

Before anything publishes, a cost analyst checks the ranges against real recent quotes.

5

Continuous refresh

As prices move through 2026, guides and tools are re-priced so what you see stays current.

Because they're model-based, real quotes will vary with site conditions, material choices and local demand. Always confirm with a licensed pro before budgeting.
