How to use this calculator
- Enter Total cost in $.
- Enter Area in sq ft.
- Press Calculate. The highlighted row is your order quantity; the note beneath it translates the number into real-world terms.
Formula & constants
Cost per sq ft = total price ÷ area — the universal comparison metric across quotes, materials and finished construction. Compare like scopes only: site work and permits skew raw numbers. Every default in the fields above is editable — when your supplier’s spec sheet lists a different density, coverage rate or price, enter that number instead. The waste and compaction allowances follow common trade practice; see our methodology page for the derivation of each formula and the standards it references.
Where this fits in the project
Efficiency upgrades interact: better insulation and correct R-values shrink the heating and cooling load, which shrinks the solar array needed to offset it. Size loads first, generation second.

Frequently asked questions
What does new construction cost per sq ft?
US 2026 averages $150–$250/sq ft for standard single-family builds — metro coasts run well past $300.
Why do two quotes differ per sq ft?
Scope — one may include demolition, site work or upgraded finishes. Normalize the scope before comparing the number.

Estimates are for planning. Material densities, coverage rates and prices vary by region and supplier — confirm final quantities before ordering, and check local code where structural or electrical work is involved.
