Frequently Asked Questions
How do I calculate investment returns?
Use the formula: Return = Final Value - Initial Investment. For percentage return: ROI = (Final Value - Initial Investment) / Initial Investment × 100.
What is a good ROI for investments?
The S&P 500 historically averages about 10% annual return. A good ROI depends on your risk tolerance — stocks average 7-10%, bonds 2-4%, real estate 8-12%.
How does compound interest grow investments?
Compound interest earns returns on both your principal and previously earned interest. Over time this creates exponential growth — $10,000 at 8% annual return becomes $46,610 in 20 years.
