More than a material takeoff

Better estimates start with better cost inputs.

ContractorCalc covers both sides of the bid: the physical quantities required to perform the work and the business math required to earn a return. Material calculators are intentionally conservative and expose waste assumptions. Pricing calculators separate markup, margin, owner pay, burdened labor, and overhead.

Use these tools as a fast planning layer, then check the result against site conditions, plans, supplier quotes, manufacturer instructions, insurance rates, and your own production history.
