About

Purple Peak is a collection of finance calculators.

Currently have a rent-vs-buy calculator, mortgage calculator, home affordability calculator, and an investment calculator.

The rent-vs-buy calculator is really cool - better than any other one I could find online and full of insightful visualizations. Check it out here.

Motivation

Partly, I was restless after finishing my previous project and wanted an excuse to try out Shadcn/UI. I was pretty late to the party, and this was back when AI was still barely good enough to do UI. Now Shadcn/UI is table stakes for me, but this was a cool starting project. Finance calculators are a great way to play with UI components without building a backend.

But the real reason: I’ve been heavily weighing the whole rent vs. buy debate for myself. I live in a very high cost of living area, and every calculator I tried had flaws in its finance logic or straight-up bugs, so they were giving me inaccurate numbers.

So I put a lot of time and energy into making sure this one is actually accurate.

The verdict? It’s heavily convinced me that buying in my current market would be a horrible idea.
