Own or Rent is a free web-based calculator suite that uses data visualization to help users compare renting versus buying a home and plan mortgages. It offers transparent, industry-standard calculations and intuitive charts to support data-driven housing decisions.
What is Own or Rent?
Own or Rent is a pair of interactive financial calculators—a Rent vs Buy Calculator and a Mortgage PITI Calculator—that run entirely in the browser. Users input financial details (income, savings, property price, rent, loan terms) and receive side-by-side visual comparisons of long-term costs. The tool is free to use with no sign-up required, created by an independent team focused on transparent financial modeling.
