About us

We build simple, honest tools that help people understand the biggest purchase of their lives.

What we make

Monthly Mortgage Calculator is a free tool for estimating the real cost of a home loan. Instead of a single number, it shows your full monthly payment — principal, interest, taxes, insurance, PMI, and HOA dues — broken down with interactive charts you can adjust in real time.

You can compare two loans side by side, see how your balance falls over the years, and share your exact calculation with a spouse, agent, or lender through a single link.

Why we built it

Most mortgage calculators bury the details, gate features behind sign-ups, or push you toward a lender. We wanted the opposite: an instant, visual tool that respects your time and your privacy. No accounts, no sales calls, no fine print designed to confuse you.

Our approach to your data

Every calculation runs entirely in your browser. Nothing you enter is sent to a server. When you share a link, your numbers are encoded directly in the URL — so you stay in control of who sees them. Read more in our Privacy Policy.

Not financial advice

Our estimates are for informational purposes only. They are not financial advice, a loan offer, or a guarantee of terms. Always confirm figures with a licensed mortgage professional before making a decision. See our Terms of Service for details.
