I Build Practical Tools That Are Easy to Use
Everything is designed to make scenarios easy to understand, compare, and sanity-check.
The S&P 500 Calculator started as a tool I built for myself. When I tried to model my own investing, most calculators were either hard to use or missing the outputs I actually needed.
So I built the version I wanted to use:
- 4 calculation modes to solve different questions, not just one final number
- Clear visual comparisons, so you can see how contributions, gains, and inflation affect results over time
- Charts and icons that guide your eye, instead of dense tables you have to decode
- Year-by-year breakdown, showing exactly how your balance evolves
- Transparent assumptions, with every input visible and adjustable
I hope it helps you plan and compare scenarios more clearly.
