FAQ

Frequently asked questions

How accurate are these construction calculators?

Our calculators provide planning-level estimates based on national US averages for materials and labor. Actual costs vary by state, city, site conditions, and contractor. Use results for budgeting and material shopping — always get quotes from licensed local pros for final numbers. Start with the house build calculator for whole-home budgets or browse all calculators by category.

Are the calculators free to use?

Yes, every calculator on EstiCube is completely free. No account required, no hidden fees, and no email sign-up. Popular tools include concrete, roofing, and parking lot striping.

What units do the calculators use?

All calculators use US customary units: feet and inches for dimensions, square feet for area, gallons for water volume, PSI for water pressure, and US dollars for cost estimates.

Can contractors use these calculators?

Absolutely. Contractors, landscapers, and pavement crews use EstiCube for quick on-site material takeoffs and client estimates. Results include material quantities and separate labor line items — pair tools like asphalt with sealcoating or pothole repair for full pavement bids. Every commercial calculator also has a contractor bid mode for markup and proposals.

Can I turn an estimate into a proposal or bid?

Yes. On the parking lot and pavement calculators, switch the results to Contractor bid. Add overhead, profit, contingency, sales tax and extra line items, enter your company details and logo, and print the one-page proposal or save it as a PDF. The proposal link carries your pricing and the client name, so the customer opens the same document in their browser. Property managers can budget a whole year with the parking lot maintenance planner, and contractors looking for work can request leads.
