Amount currently invested

Total value of all of your current investments. Although you could include your home and personal property in this amount - it is a bit more accurate to include only your savings, retirement accounts and investments.

Savings per month

The amount you will contribute each month to your investments. This calculator assumes that all savings are added to your account at the beginning of the month.

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 31^st 2023, had an annual compounded rate of return of 15.2%, including reinvestment of dividends. From January 1, 1970 to December 31^st 2023, the average annual compounded rate of return for the S&P 500®, including reinvestment of dividends, was approximately 10.9% (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 2023 the CPI has a long-term average of 3.0% annually. Over the last 40 years the highest CPI recorded was 13.5% in 1980. For 2023, the last full year available, the CPI was 3.1% annually as reported by the U.S. Bureau of Labor Statistics.
