Cost Scenario FAQ

What is a cost scenario?

A cost scenario is a prebuilt estimate for a common project size, such as a 20x20 concrete patio, a 12x12 deck, or replacing 10 windows. It gives you a fast baseline before you enter your own measurements.

Should I use a scenario page or a calculator page?

Use a scenario page when your project matches a common size or search query. Use the full calculator when you need to adjust dimensions, material grade, labor assumptions, or project complexity.

Are scenario estimates exact quotes?

No. Scenario estimates are planning ranges based on typical U.S. costs. Final quotes depend on local labor rates, material availability, access, permits, and hidden site conditions.
