- Original investment
- The amount of your investment before suffering your losses. This is the total you are looking to recover, or eventually have in your account.
- Current value
- Your current remaining balance after your losses.
- Additional contributions
- The amount you will contribute each period to your account. This calculator also assumes that you make your contribution at the beginning of each period.
- Expected rate of return
- This is the annually compounded rate of return you expect from your investments. For the purposes of this calculator, taxation is not factored into the results. If you pay taxes on the interest, dividends or capital gains from these investments you may wish to enter your after-tax rate of return.
The actual rate of return is largely dependent on the types of investments you select. The Standard & Poor's 500® (S&P 500®) for the 10 years ending December 31st 2021, had an annual compounded rate of return of 13.6%, including reinvestment of dividends. From January 1, 1970 to December 31st 2021, the average annual compounded rate of return for the S&P 500®, including reinvestment of dividends, was approximately 11.3% (source: www.spglobal.com). Since 1970, the highest 12-month return was 61% (June 1982 through June 1983). The lowest 12-month return was -43% (March 2008 to March 2009). Savings accounts at a financial institution may pay as little as 0.25% or less but carry significantly lower risk of loss of principal balances.
It is important to remember that these scenarios are hypothetical and that future rates of return can't be predicted with certainty and that investments that pay higher rates of return are generally subject to higher risk and volatility. The actual rate of return on investments can vary widely over time, especially for long-term investments. This includes the potential loss of principal on your investment. It is not possible to invest directly in an index and the compounded rate of return noted above does not reflect sales charges and other fees that investment funds and/or investment companies may charge.
- Expected inflation rate
- This is what you expect for the average long-term inflation rate. A common measure of inflation in the U.S. is the Consumer Price Index (CPI). From 1925 through 2021 the CPI has a long-term average of 2.9% annually. Over the last 40 years the highest CPI recorded was 13.5% in 1980. For 2021, the last full year available, the CPI was 6.8% annually as reported by the U.S. Bureau of Labor Statistics.
- Adjust for inflation
- Check this box to show all results adjusted for inflation. The rate of return is effectively lowered to compensate for any investment return you received that simply allows you to maintain the purchasing power of your investment.
