I'm Hank Zouho, a writer and a lifelong geek. ZFinPro Tools is my free collection of financial calculators, built to make everyday money questions simple, fast and accessible to everyone, across several languages and currencies.
The writer side
When I'm not building tools, I write. My book Exploring Origins: Science, Faith, and the Pursuit of Truth explores the big questions at the crossroads of science and meaning.
The geek side
I love clean code, fast websites and genuinely useful tools. Every calculator here runs instantly in your browser, with no signup and no tracking of what you type.
Have feedback or an idea for a new tool? I'd love to hear from you on the contact page.
