How we estimate construction cost

SimpleHome gives a fast, transparent planning estimate — not a tender or quotation. Here's exactly how the numbers are built, what they include, and where they stop.

The rate model

Every estimate starts from a standard per-sq-ft rate for your state, then adjusts it for the things that actually move cost:

Your total is that effective rate × your built-up area, plus a lift where one is needed.

Data & updates

Rates are anchored to a base table dated November 2025 and auto-adjusted forward for inflation, so the figure you see reflects current-year pricing. They're thumb-rule benchmarks tuned by state and city type — useful for planning and comparison, not a substitute for a measured estimate.

Accuracy & disclaimer

Treat every figure as a ballpark for early planning. The likely-range band widens for larger and taller builds, which are inherently less certain. For a real budget — and anything used for a loan, tender or contract — you need drawings, a soil test and an item-wise estimate (BOQ) from your architect, engineer or contractor.
