Frequently Asked
Are the calculators really free?
Yes. All 41 construction calculators are completely free to use with no sign-ups, no usage limits, and no hidden fees. You can generate PDF and Excel documents at no cost.
Can I use this for commercial projects?
Absolutely. Contractors and builders use BuildingCalc daily for client quotations and material take-offs. The PDF and Excel exports are designed for professional use.
Is my data stored on your servers?
No. All calculations run entirely in your browser. Your project data never leaves your device. PDF/Excel generation is processed in temporary memory and discarded immediately after the file is sent to you.
How accurate are the calculations?
Our calculators use industry-standard formulas. However, all results are estimates. We recommend verifying calculations with local building codes and consulting with licensed professionals for critical projects.
