Compounding Intervals

This calculator not only allows you to compute and compare the forecasted interest earnings on various investment scenarios, but it also allows you to choose the deposit and compounding intervals. No longer will you need to wonder if an investment offering a 6% return, compounded daily is better than an investment offering a 7% return, compounded annually.


Instructions:  To calculate the forecasted earnings of an investment, enter the beginning balance, the amount you plan to add to your investment (if any) at the specified intervals, the interest rate you expect to earn and the compounding interval, and the number of years you expect to allow your investment to grow. Since varying deposit and compounding intervals lead to very complex calculations and considering the actual earnings of an investment may be calculated using any one of several methods, the results calculated by this tool should be considered as estimates only.


Note: When entering numbers into the data fields only use numbers and applicable decimal points. Entering commas, dollar signs, or any other non-numeric characters will cause an error. Also please note that this calculator has been tested to work with Internet Explorer 3.01 and Netscape Navigator 3.01 web browsers. However, both must have the JavaScript option turned on (5594 bytes)
