Why another mortgage calculator site?

Because most mortgage calculators online are lead-generation forms wearing a calculator costume: they show you principal and interest only (making homes look a quarter cheaper than they are), then sell your phone number to lenders. Zorvex works differently. Every tool here includes the costs others hide — property taxes, homeowners insurance, PMI, FHA mortgage insurance, the VA funding fee — explains its formula in plain English, and runs entirely in your browser. We never see, store or sell a single number you type.

Frequently asked questions

Is this mortgage calculator really free?
Yes — every calculator and guide on Zorvex.codes is free, with no account, no email capture and no usage limits. The site is supported by advertising.
How accurate are the results?
The math uses the standard amortization formulas lenders use, so principal and interest figures are exact for the inputs you give. Taxes, insurance and PMI are estimates — your lender's Loan Estimate remains the authoritative document for a real purchase.
Is my data private?
Completely. All calculations run in your browser with JavaScript. Nothing you type is transmitted to or stored on any server — you can verify this by loading a calculator and switching your device to airplane mode: it still works.
Which calculator should I start with?
If you are shopping: the affordability calculator first, then the payment calculator on real listings. If you already own: the payoff calculator and refinance calculator show the biggest savings opportunities.
