Overview

This is a Streamlit-based portfolio simulation tool that helps visualize long-term investment growth using a rational investing approach, as outlined in Investing Demystified by Lars Kroijer. The tool allows users to model their retirement savings (e.g., SIPP) using a mix of global equity index funds and government bonds, accounting for inflation, returns, and volatility.

Features

• Customizable Inputs:
  • Starting portfolio amount
  • Annual inflation rate
  • Variable monthly contributions and allocation
• Monte Carlo simulations assuming each asset has a fixed average return and constant volality.
• Backtesting using historic returns from Yahoo! finance
• Interactive visualization of portfolio growth over time using Plotly.
