Frequently Asked Questions
Are your calculators free to use?
Yes, all calculators on BuildFormulas are completely free. We support the site through advertising and affiliate partnerships, which means no cost to you.
How accurate are the calculations?
Our calculators use standard industry formulas and provide reliable estimates for planning purposes. However, every construction project and financial situation is unique. Always verify with a licensed professional and add appropriate safety margins before making purchasing or financial decisions. Our tools are designed for planning and educational purposes only.
Do you store my calculator inputs?
No. All calculations happen entirely in your browser using client-side JavaScript. We do not collect, store, or transmit any of the values you enter into our calculators. Your privacy and data security are important to us. We do not use any tracking that collects personal calculator data.
Can I suggest a new calculator?
Absolutely! We are actively expanding our tool collection and love hearing ideas from our users. Use the form above and select "Calculator Suggestion" as the subject, or email us directly at suggest@buildformulas.com. We review every suggestion and prioritize the most-requested tools.
