About This Scenario
A one-time $10,000 investment at 8% annual returns grows to about $100,600 over 30 years — more than 10x your initial investment, with zero additional contributions. At 10% (S&P 500 average), it grows to about $174,500. This demonstrates the raw power of compound growth: even a single investment, left untouched, can multiply many times over.
