Construction Cost Calculator Formula

  1. Total Built-up AreaBuilt-up Area × Floors (converted to sqft)
  2. SubtotalTotal Built-up Area × Cost per Sqft
  3. ContingencySubtotal × (Contingency % ÷ 100)
  4. Estimated Total CostSubtotal + Contingency

Assumptions

  • Cost per sqft values are indicative averages and vary by region and market conditions.
  • Breakdown percentages represent typical residential construction splits.
  • Contingency should cover design changes, price fluctuations, and unforeseen site conditions.

Frequently Asked Questions

How accurate is the construction cost estimate?

The estimate provides a planning range based on quality tier and built-up area. Final costs depend on local labour rates, material prices, and project specifications.

What does built-up area include?

Built-up area typically includes all floor levels measured to external walls. Enter the per-floor area and multiply by the number of floors.

Why add a contingency percentage?

Contingency reserves budget for unexpected expenses such as scope changes, delays, or price increases during construction.
