Monte Carlo Real Estate Investment Calculator

This calculator is designed to estimate returns on real estate rental investments — with a twist: it's built to handle uncertainty properly.


Instead of entering a single number for each input, you provide Best, Worst, and Most Likely values. Thousands of simulations are run, each selecting random inputs from your specified ranges and computing a different result. Looking at thousands of results reveals the probability distribution of investment returns — a technique called Monte Carlo Simulation.

Google Chrome Extension for AI Analysis of News Stories

A Google Chrome Extension that analyses news stories and provides per-capita analysis of financial data using Anthropic's Claude Sonnet API. Submitted as an entry for Anthropic's 'Build with Claude' contest.

The extension extracts location and financial data from any news story and displays a table of per-capita values — helping put large numbers in context. For example, a $10B infrastructure announcement looks very different on a per-capita basis in a city of 500,000 vs. a country of 40 million.
