Frequently Asked Questions
Are all calculators on Home & Car Calc completely free?
Yes. All 54 calculation tools on this website are 100% free to access without subscription paywalls, registration forms, or email requirements.
Is my personal financial data saved on your web servers?
No. All calculation models execute exclusively on your local client device using browser-based JavaScript. No personal property valuations, loan balances, or income figures are ever sent to our servers.
How do I report a calculation issue or recommend a new tool?
Please send an email to support@homeandcarcalc.com with the calculator name, specific input parameters, expected output, and any relevant formula documentation. We review every suggestion carefully.
Do calculators function without an active internet connection?
Yes. Because the entire calculation engine executes via client-side JavaScript, once the page is initially loaded into your web browser, all computations operate locally without requiring ongoing internet connectivity.
How frequently are interest rates and tax benchmarks updated?
The calculators provide deterministic mathematical models where you input current market interest rates and localized tax millage rates. While we do not scrape live commercial rates, our default illustrative inputs are reviewed periodically against prevailing economic averages.
Feedback Submission Guidelines
When reporting an issue with a formula, providing the exact numerical inputs used along with the expected result from official loan documentation or banking statements helps us review and adjust the underlying mathematical logic quickly. We appreciate screenshots and worked step-by-step examples.
Educational Collaboration & Independent Review
We actively collaborate with personal finance educators, housing counseling non-profits, and independent financial bloggers who value open-source educational calculators. If you wish to suggest joint educational resources or verify calculation algorithms for classroom use, we welcome your outreach.
Website Accessibility and Technical Support
We are dedicated to ensuring digital accessibility for all visitors. If you encounter any screen reader issues, color contrast difficulties, or navigation barriers while using our calculators, please contact our support team so we can promptly address and resolve any accessibility concerns.
