Construction cost calculator.

Estimate the cost to build your house or building. Enter the area, number of floors and finish quality — get a per-square-foot estimate with a material and labour breakdown.

Project details

Tip: pick a finish level to auto-fill a typical rate, or type your own local rate. Rates vary by city, material prices and site conditions.

This is a ballpark estimate for early budgeting. A precise cost needs a Bill of Quantities (BOQ) from real drawings — which is exactly what a BIM model gives you. ClickBit Digital produces quantity-accurate estimates from 3D and BIM models.

How construction cost is estimated

The fastest way to budget a building is the per-square-foot method: multiply the total built-up area by a rate that reflects your finish quality and local prices. It is not exact, but it gets you a realistic starting number before any drawings exist.

Built-up area is the floor area multiplied by the number of floors. The rate per square foot bundles together structure, brickwork, plaster, flooring, electrical, plumbing, doors, windows and finishing. Economy finishes sit at the low end, standard finishes in the middle, and premium finishes — imported tiles, designer fittings, false ceilings — at the top.

Why a BIM model gives a better number

A rule-of-thumb rate is fine for a first budget, but it can be off by a wide margin. The accurate way is to model the building in 3D, then let the software count every element — cubic metres of concrete, kilograms of steel, square metres of tiles — and price them. That is a Bill of Quantities driven by a BIM model, and it removes the guesswork. It also catches clashes and design problems before they cost money on site.

What drives cost up or down

Is this calculator accurate for Bangladesh?

It uses the per-square-foot method common across Bangladesh, with editable rates so you can match current local prices. For a firm number, get a BOQ from actual drawings.

Does the estimate include land and design fees?

No. This covers construction only — structure, finishing and basic services. Land, government fees, design and consultancy are separate.

Can ClickBit Digital give an exact quote?

Yes. From your drawings or a BIM model we produce a quantity-accurate BOQ and cost estimate. Call +880 1886-684876.
