MissedAlpha is a free historical ROI (Return on Investment) calculator that shows you exactly how much money you would have made if you had invested in stocks, cryptocurrencies, ETFs, and other assets at a specific date in the past. Think of it as a financial time machine.

We use a professional-grade simulation engine that goes far beyond simple percentage calculations. Our system accounts for stock splits, cash dividends, dividend reinvestment (DRIP), inflation adjustments, and real-time multi-currency conversions using historical daily exchange rates.

Use our Bitcoin ROI Calculator to find out! Bitcoin has been one of the best-performing assets in history. A $1,000 investment in Bitcoin in July 2010 (when it was ~$0.06) would be worth billions of dollars today. Try it yourself with our calculator for the exact number based on your chosen date.

Yes! We automatically adjust all historical calculations for stock splits and reverse splits. For example, if you look up Apple (AAPL) or Nvidia (NVDA), our engine correctly accounts for their multi-split histories to show you an accurate share count and return.

Absolutely. We track historical cash dividend payments for all dividend-paying stocks. Our calculator shows your "Total Return" including dividend income — not just price appreciation. This gives you the true picture of investment performance.

MissedAlpha covers over 100,000 assets globally including: US Stocks & ETFs (NASDAQ, NYSE, AMEX), Cryptocurrencies (BTC, ETH, SOL, and 10,000+ altcoins), International Markets (London, Tokyo, Toronto, Istanbul/BIST exchanges), and Commodities via ETFs (Gold, Silver, Oil).

Yes, MissedAlpha is completely free. We believe financial literacy should be accessible to everyone. You can calculate returns for any asset, any date, any amount — without paying a cent.

We aggregate data from multiple premium financial APIs and cross-reference historical events (splits, dividends, delistings) to ensure high precision. While no data source is perfect, we continuously validate and improve our data quality.

Yes! MissedAlpha supports multi-currency calculations. If you are investing from Turkey, Europe, or anywhere else, our engine uses daily historical exchange rates to show you the true return in your local currency, accounting for currency appreciation or devaluation.

"Alpha" in finance refers to excess returns above a benchmark. "Missed Alpha" represents the returns you could have earned but didn't — the opportunity cost of not investing. Our tool quantifies this exact number to help you understand the power of long-term investing.
