Formula and method

What this calculator is useful for

Calculate cost per square foot or total project cost from area and total price. The result is intended for quick estimates, checking arithmetic and comparing scenarios. When a result affects a contract, tax filing, medical decision, building-code requirement or other high-stakes situation, verify the result with the appropriate professional or authoritative source.

Use matching area definitions for comparisons

A $45,000 job across 1,500 measured square feet costs $30 per square foot. This is useful for normalizing two bids of different total sizes.

What to check: Usable area versus gross area, ceiling height, demolition, permit costs, and scope exclusions may differ between bids. A lower rate per square foot does not guarantee a lower final project bill.

Compare with the Square Footage calculator when that better matches the question you are trying to answer.
