Investment Simulator Methodology | Data Sources & ROI Calculation

Our Investment Methodology

Discover how we calculate past performance for your simulations using reliable, real-world market data and simple investment logic.

📊 Data Sources

Our simulator pulls historical price data from:

  • ✔️ Google Sheets as the central data hub
  • ✔️ Yahoo Finance for stock and ETF price history
  • ✔️ CoinGecko for crypto price data

📈 How We Calculate Investment Returns

Our simulator calculates final investment value based on the strategy you choose:

  • Lump Sum: The full amount is invested on the start date, and value is tracked over time.
  • DCA (Dollar-Cost Averaging): Investment is spread over time with the selected frequency (daily, weekly, monthly, etc.). Each portion is invested at the corresponding price.

⚠️ Assumptions and Limitations

While our simulator uses real market data, some assumptions are made:

  • No transaction fees or taxes are considered
  • Prices are closing prices (daily granularity)
  • Data accuracy depends on source availability
