About HouseMath

HouseMath builds simple calculators for buying, owning and paying off a home. Each one answers a single question quickly, shows the numbers behind the answer, and explains how the math works.

How the calculators work

All calculations run in your browser. Nothing you type is sent to or stored on our servers. The formulas are the standard ones lenders use, and each calculator page explains its assumptions.

Estimates, not advice

Results are estimates for planning. They are not financial, tax or legal advice. HouseMath is not a lender, broker or financial advisor. Confirm figures with your lender, tax professional or advisor before making a decision. See our terms of use and disclaimer.
