I found a calculation error — what do you need?

Tell us the calculator name and the inputs you used. We'll reproduce it, fix it if confirmed, and add a regression test so it can't recur.

Do you offer phone or live-chat support?

No. Email is the only support channel. It keeps inquiries documented and searchable for both sides.

Can I get personalized financial, tax, or legal advice?

No. We answer questions about how our calculators work and how the math behind them is structured. Specific personalized advice belongs with a licensed professional.

Will my email be used for marketing?

No. Your email is used only to reply to your message. We don't run a newsletter, marketing automation, or remarketing.

Questions, feedback, bug reports, or partnership ideas? Get in touch — we read every message.

Email hello@carfinancetools.com — we read every message and reply by email. There is no contact form, no third-party CRM, and no auto-responder.

How to reach us

The fastest way to reach us is email: hello@carfinancetools.com. We aim to reply within a few business days. Messages go directly to a human.

What we'll respond to

Calculation issues. If a result looks wrong, send the calculator name and the inputs you used so we can reproduce it. We treat correction reports as a priority. See our editorial policy for how we maintain calculation accuracy.
Feedback and feature ideas. Tell us what's missing, confusing, or valuable to you.
Partnership and collaboration ideas. Credit unions, educators, and writers covering personal finance — we're listening.
General questions about how the calculators work. Each calculator's “How this is calculated” section is the deepest answer; if it doesn't cover your case, ask us.

Why there's no contact form

Contact forms route messages through a third-party service that stores your name, email, and message. We didn't want that. Direct email keeps your inquiry between you and us, gives you a record of the thread in your own inbox, and avoids one more place where your data has to live. It's the same reason calculator inputs never leave your browser.
