Understanding Investment Returns

Investing is about putting your money to work so it can grow over time. Understanding your returns is crucial for evaluating strategy performance. **Key Metrics Calculated:** 1. **Total Return:** The absolute percentage growth of your portfolio, accounting for capital gains and dividends. 2. **CAGR (Compound Annual Growth Rate):** The mean annual growth rate of an investment over a specified time period longer than one year. It smooths out the volatility of periodic returns. 3. **Dividend Reinvestment:** Strategies where earnings or dividends are used to buy more shares, accelerating compound growth.

Investment Return Questions

Q:What is a good CAGR?

A "good" CAGR depends on your risk tolerance and asset class. The S&P 500 has historically returned about 10% annually (before inflation). Safe bonds might return 3-5%, while high-growth stocks could exceed 15-20% but with higher risk.

Q:What is the difference between Simple Return and CAGR?

Simple return just looks at total profit / total investment. CAGR accounts for the time value of money, telling you what constant annual rate would get you from your starting value to your ending value over that specific time period.

Q:Does this calculator account for inflation?

This standard calculator uses nominal returns. To estimate "real" returns, you should subtract the expected inflation rate from your annual return input.
