We would love to hear from you.

If you have a question, a calculator idea, or noticed something wrong, email is the fastest way to reach us.

We reply within a few business days.

What to write about

Suggest a calculator. Tell us what you wish existed. If enough people ask, we'll build it.
Report an error. If you found a bug, a typo, or a formula that looks off, send us the page link, the inputs you used, and what you expected to see.
Partnerships and press. If you want to collaborate, cite a calculator, or feature CalcFinity, drop us a note.
Privacy requests. GDPR, CCPA, or general privacy questions go to the same address. Our Privacy Policy lists the full set of rights.

What we can't do

We cannot provide financial, legal, tax, real estate, medical, or any other kind of professional advice. For decisions that affect your money, property, or health, please talk to a qualified professional. Our Disclaimer explains why.

Not an emergency line

CalcFinity is an online tool. It is not a service provider and we do not monitor email around the clock. If you are facing a financial, legal, or safety emergency, please contact a qualified professional or the appropriate emergency service in your area.
