Calculate compound returns and future value of your investments
Project the future value of your investments with our free compound interest calculator. Whether you're investing in stocks, bonds, mutual funds, or retirement accounts, understanding the power of compound growth is essential for building long-term wealth. This calculator helps you visualize how your money can grow over time.
Enter your initial investment amount, expected monthly contributions, anticipated annual return rate, and investment timeframe. The calculator then applies compound interest formulas to show your future portfolio value. You can also factor in inflation to see the real purchasing power of your future wealth and estimate taxes on your investment gains.
The investment return calculator uses the compound interest formula to project your investment growth. First, enter your initial investment or starting principal. Then, specify any regular monthly contributions you plan to make. The calculator applies your expected annual return rate, compounded monthly, to both your initial investment and ongoing contributions throughout your investment period.
For the most accurate projection, consider using realistic return expectations based on your investment allocation. Conservative investors might expect 4-6% returns, while aggressive investors might target 8-10% or higher. Remember that past performance doesn't guarantee future results, and investment returns can vary significantly from year to year.
The calculator also accounts for inflation by adjusting your future value to today's purchasing power and estimates taxes on your investment gains based on your tax rate. This gives you a realistic view of your after-tax, inflation-adjusted returns, helping you plan more effectively for long-term financial goals like retirement.
Compound interest is interest calculated on both your initial principal and accumulated interest from previous periods. This creates exponential growth over time, especially with regular contributions. The longer your investment timeline, the more powerful compound growth becomes, making it a key factor in building long-term wealth.
Historical stock market returns average around 7-10% annually before inflation. Bonds typically return 2-5%. Your expected return depends on your asset allocation. Conservative portfolios might expect 4-6%, while aggressive portfolios might target 8-10%. Use realistic expectations based on your investments and risk tolerance.
Inflation reduces the purchasing power of money over time. A 10% return with 3% inflation means your real return is only 7%. The calculator shows both your nominal future value and your inflation-adjusted real value, helping you understand what your future wealth will actually buy in today's dollars.
Yes, taxes significantly impact your actual investment returns. Different investment types are taxed differently – qualified dividends and long-term capital gains are typically taxed at lower rates than short-term gains or ordinary income. The calculator lets you specify your tax rate to estimate your after-tax investment value.
Start with what you can comfortably afford and increase contributions over time as your income grows. Financial experts often recommend saving 10-20% of your income for retirement, including any employer match. Use this calculator to see how different contribution amounts affect your long-term investment growth.
