Free, Private, and Fast
Financial Calculators for Everyone.
We built PenGenie because we believe that essential salary, tax, and career calculators should be private, run in-browser, and be supported by minimal, non-intrusive advertising instead of expensive financial subscriptions.
The Story
As a computer science student, I found myself constantly frustrated by the landscape of online financial utilities. Many tools were difficult to compare, filled with opaque assumptions, or built primarily around lead capture.
For students, professionals, and households, comparing financial scenarios should not be stressful. I realized there was a gap for a clear, privacy-first financial planning suite built around free browser-based calculators.
That's how PenGenie was born. We started as an open-source experiment around practical planning tools. Today, we offer specialized calculators for mortgages, debt, savings, retirement, taxes, paychecks, and career decisions.
PenGenie is an independent utility platform, not a government service or official tax authority. Our calculators provide planning estimates based on the assumptions shown on each page; users should confirm important figures with current official documentation.
