Calculator results on CalcRuvo are estimates based solely on the numbers you enter and the formulas described on each page.

• They are not professional accounting, tax, legal, or engineering advice.
• They do not account for local codes, taxes, market conditions, or site-specific factors unless you include them.
• Material quantities and costs should be confirmed with suppliers before ordering or quoting.
• Sales tax is only included where you enter it; tax treatment of construction and repair work varies by location.
• Concrete and other quantity results are not structural or engineering designs.
• Printed estimates and change orders are proposals. Whether they are binding depends on your contract and applicable law.
• Results are cost-based recommendations. They do not guarantee profit or that the market will accept the price.

Always review results with your own judgment, and consult a qualified professional when the stakes warrant it.
