How it Works & Explanation
Calculates the future value of an investment using compound interest and periodic monthly contributions.
Healthy Tips & Guidelines
- Start investing as early as possible to maximize the power of compound interest.
- Reinvest your dividends rather than withdrawing them to accelerate growth.
- Use a realistic annual return rate based on historical market data (e.g., 7-10% for stock indexes).
Common Mistakes to Avoid
- Confusing simple interest with compound interest; compound interest grows much faster over long periods.
- Forgetting to account for inflation, which reduces the real purchasing power of your future money.
- Setting an unrealistically high interest rate, leading to false expectations.
