Portfolio Performance is an open-source desktop application for tracking and evaluating investment portfolios across multiple accounts and brokerages. It computes performance metrics like True-Time Weighted Rate of Return and Internal Rate of Return, imports transactions from PDF/CSV, and fetches historical quotes from many online sources.

Use cases

  • track my investment portfolio performance across multiple brokers
  • calculate true time-weighted rate of return and IRR for my holdings
  • import broker transactions from PDF or CSV statements
  • download historical stock and crypto prices automatically
  • rebalance my portfolio against a target asset allocation
  • track stocks, ETFs, and cryptocurrencies in one tool
  • export my portfolio data as XML or CSV

When to choose

  • you want a free, open-source desktop app for detailed portfolio tracking
  • you need rigorous performance metrics like TWR and IRR across accounts
  • you want automatic quote downloads from many sources including Yahoo, Alpha Vantage, and CoinGecko
  • you value an open XML file format and CSV export
  • you need multi-currency support with ECB exchange rates

When to avoid

  • you need a mobile-first or web-based portfolio tracker
  • you want fully automated bank syncing without manual transaction entry
  • you prefer a simple app without a learning curve for booking transactions
  • you need tax reporting tailored to a specific country out of the box
