ProjectFigure's calculators give good-faith estimates to help you plan and shop. They are not professional, engineering, building or financial advice.
Real projects vary — site conditions, local building codes, product specifications and supplier batch sizes all matter. Always confirm quantities and requirements with your supplier and, for anything structural or safety-related, a licensed professional, before you buy materials or begin work. We take care to get the formulas right but make no warranty of accuracy and accept no liability for losses arising from use of the calculators.

Some outbound links to products are affiliate links: if you click one and make a qualifying purchase, we may earn a commission at no additional cost to you. This never changes the price you pay, and we only suggest products relevant to your calculated result.
