Honest Math is a financial planning resource that makes professional-grade Monte Carlo simulation accessible to everyone. With flexible portfolio settings, customizable investment parameters, and enhanced statistical modeling, Honest Math offers users a free, high-powered alternative to traditional “retirement calculators.”

The internet is giving people more power than ever to take control of their personal finances. We love seeing the growth of the financial independence movement, but it bothers us tremendously that some of the most popular "retirement calculators" and "FIRE" tools on the web are terribly flawed. Our mission is to provide investors with better information and software.
