ABOUT HOMEMATH

Home finance, made clear.

We built HomeMath because the biggest financial decision most people make shouldn't require a finance degree to understand.

Last updated: March 2026

The problem

Most mortgage calculators give you a wall of numbers and leave you to figure out what they mean. Should you refinance? Is buying smarter than renting? How much house can you actually afford? The answers are buried in spreadsheets and jargon.

HomeMath is different. Every calculator gives you a plain-language verdict — yes, no, and exactly why — so you can make decisions with confidence, not confusion.

What makes us different

🎯
Verdicts, not just numbers
Every calculator tells you what the numbers mean. A clear recommendation at the top — not a spreadsheet you have to interpret.
🆓
Always free, no signup
No account required. No email gate. No paywall. Enter your numbers, get your answer. That's it.
⚖️
Independent & unbiased
We're not a lender. We don't sell loans. Our calculators give you the same answer whether you refinance or not — because we have no stake in your decision.
🔒
Your data stays yours
Every calculation runs entirely in your browser. We never see, store, or transmit your financial data. Period.

Our independence pledge

HomeMath displays links to mortgage lenders. When you click these links, we may earn a referral fee. This is how we keep the site free.

But here's what matters: affiliate partnerships never affect our calculator results. The math is the math. If refinancing doesn't make sense for you, we'll tell you — even if a lender would pay us when you click.
