CalcMoney vs. Zillow

Zillow is the dominant real estate marketplace. We are the calculator-first alternative for mortgage math. Here is how the two stack up when you need to run the numbers.

CalcMoney

Built around deep mortgage math. Full PITI breakdown, full amortization schedule with chart, free scenario saving, and a free AI insight and PDF export before Pro unlocks unlimited use. Plus 90 calculators across retirement, tax, debt, and investing: not just home buying.

Zillow

The largest home listing platform in the US, and the #1 result for "mortgage calculator" (2.2M monthly searches). Mortgage calculator is a small part of their product, embedded in listings. Strong for browsing homes, checking Zestimates, and getting a quick payment estimate on a specific property. Not built for financial planning depth.
