Historical Stock Calculator — What If You Had Invested Then?

See what a past investment in famous stocks would be worth today

Quick Answer

$10,000 invested in Apple in January 2003 would be worth approximately $3.2 million today. The same amount in Amazon in 2001 would be worth $2.8 million. $10,000 in the S&P 500 index fund in 2000 would be worth approximately $64,000 today — a 540% return. Individual stock selection produces dramatically different outcomes versus index fund investing.

A historical stock calculator shows what an investment in a specific company would be worth today if made at a past date. It helps illustrate the power of long-term investing and the dramatic difference between stock selection outcomes. All results are historical and past performance does not guarantee future returns.
