Understanding Compound Interest

Compound interest is the interest calculated on the initial principal and also on the accumulated interest of previous periods. It's often called "interest on interest" and can significantly boost investment growth over time.

A = P(1 + r/n)nt
A = Final amount P = Principal amount r = Annual interest rate n = Times interest compounds per year t = Time in years

Investment Strategies

  • Dollar-Cost Averaging: Invest fixed amounts regularly regardless of market conditions
  • Value Investing: Buy undervalued assets with strong fundamentals
  • Growth Investing: Focus on companies with above-average growth potential
  • Dividend Investing: Invest in companies that pay regular dividends
  • Index Investing: Buy funds that track market indexes

Risk Factors to Consider

High Risk Individual Stocks, Crypto
Medium Risk Stock Mutual Funds, REITs
Low Risk Bonds, CDs, Treasury Notes

Higher potential returns typically come with higher risk. Diversification can help manage risk while maintaining growth potential.

Investment Calculator FAQ

How accurate are these projections?

Projections are based on the mathematical principles of compound interest and assume consistent returns. Actual investment returns will vary due to market fluctuations, economic conditions, and other factors. These projections should be used for planning purposes only.

Should I adjust for inflation?

Yes, adjusting for inflation is recommended for long-term planning. Inflation reduces purchasing power over time, so $1 million in 20 years won't have the same value as $1 million today. Our calculator shows both nominal and inflation-adjusted values.

What's a realistic annual return rate?

Historical averages: Stocks ~10%, Bonds ~4-6%, Real Estate ~7-9%. Conservative estimates typically use 4-6%, balanced portfolios 7-8%, and aggressive strategies 9-12%. Past performance doesn't guarantee future results.

How do fees affect long-term growth?

Fees have a significant impact over time due to compounding. A 1% annual fee on a $100,000 investment earning 7% for 30 years reduces the final balance by approximately $100,000. Always consider fees when choosing investments.
