What is this?
The Construction Cost Estimator projects the budget for a building project from three inputs: built-up area, the local rate per square foot, and the number of floors, with an optional percentage for additional costs. Owners use it before buying land, builders use it to frame quotes, and investors use it to sanity-check contractor bids.
The core math is area x rate, so the rate you enter carries all the meaning. Rates vary enormously by market and finish level - basic construction, standard finishes, and premium builds in the same city can differ by 2-3x per square foot - so use a rate from recent local quotes, not national averages. Multi-floor input scales the base cost linearly (two floors of the same footprint doubles the built-up area), and the additional-costs percentage models the items quotes often omit: permits, architect and structural fees, boundary walls, landscaping, and utility connections. An extra 10 percent on a 100,000 budget adds 10,000.
Read the output as a feasibility band, not a fixed price: material price swings, soil conditions, and design complexity move real projects 10-20 percent around the estimate, which is why the detail line shows base, additional, and per-floor figures for comparison.

Formula
Base Cost = Area (sq ft) x Rate per sq ft x Floors
Total = Base x (1 + Additional % / 100)
Total = Base x (1 + Additional % / 100)
