What Is Compound Interest?<\/h2>\n

Compound interest is interest earned on both your original principal and the interest already accumulated. Unlike simple interest (which only applies to the original amount), compounding causes your investment to grow exponentially over time. Albert Einstein reportedly called it “the eighth wonder of the world” — and for good reason.<\/p>\n

How to Use the Investment Returns Calculator<\/h2>\n
    \n
  1. Enter your starting amount<\/strong> — the lump sum you are investing today.<\/li>\n
  2. Set your monthly contribution<\/strong> — the amount you plan to add every month. Even small regular contributions have a dramatic effect over time.<\/li>\n
  3. Enter your expected annual return rate<\/strong> — the S&P 500 has averaged roughly 10% annually over the long term (about 7% after inflation).<\/li>\n
  4. Choose your investment horizon<\/strong> — set the number of years you plan to invest.<\/li>\n
  5. View your year-by-year projection<\/strong> — see exactly how your balance grows, how much is your own contributions, and how much is compound growth.<\/li>\n<\/ol>\n

    The Power of Starting Early<\/h2>\n

    Time is the most powerful factor in compound growth. An investor who puts $5,000\/year into an index fund at 7% return starting at age 25 will have around $1.1 million by age 65. An investor who starts at 35 with the same contributions will have about $567,000. Starting 10 years earlier more than doubles the outcome, even though the total contributions only differ by $50,000.<\/p>\n

    How Compounding Frequency Affects Growth<\/h2>\n

    Investments can compound annually, quarterly, monthly, or daily. More frequent compounding means slightly higher returns for the same stated annual rate. For example:<\/p>\n

      \n
    • $10,000 at 8% annual rate compounded annually = $21,589 after 10 years<\/li>\n
    • $10,000 at 8% annual rate compounded monthly = $22,196 after 10 years<\/li>\n
    • $10,000 at 8% annual rate compounded daily = $22,253 after 10 years<\/li>\n<\/ul>\n

      The difference between annual and daily compounding is modest, but over 30 or 40 years it becomes meaningful.<\/p>\n

      Realistic Return Rate Benchmarks<\/h2>\n
        \n
      • High-yield savings account<\/strong>: 4.5 to 5.5% (current rates, variable)<\/li>\n
      • US bonds \/ Treasury notes<\/strong>: 3 to 5%<\/li>\n
      • Diversified index fund (S&P 500)<\/strong>: 7 to 10% long-term average<\/li>\n
      • Real estate<\/strong>: 8 to 12% (highly variable by market)<\/li>\n<\/ul>\n

        For retirement planning, most financial advisors suggest using 6 to 7% as a conservative estimate for stock market returns after inflation.<\/p>\n

        Frequently Asked Questions<\/h2>\n

        Does the calculator account for inflation?<\/h3>\n

        The calculator uses a nominal return rate. To see real (inflation-adjusted) growth, subtract the expected inflation rate (historically around 3%) from your return rate. For example, use 7% instead of 10% to estimate real purchasing power.<\/p>\n

        What is the difference between CAGR and average annual return?<\/h3>\n

        CAGR (Compound Annual Growth Rate) is the smoothed annualized rate that would take your investment from its starting value to its ending value. Average annual return is the arithmetic mean of yearly returns. CAGR is more accurate for measuring actual investment performance over time.<\/p>\n

        Should I include dividends in my return rate?<\/h3>\n

        Yes — if you reinvest dividends, include the dividend yield in your total return rate. For a broad US index fund, dividends add roughly 1.3 to 1.5% to the total return.<\/p>\n","protected":false},"excerpt":{"rendered":"
