CD Calculator

How the CD Calculator Works

This calculator projects the future value of your money by combining a lump-sum initial amount with regular monthly contributions, both growing at your expected annual rate of return compounded monthly.

Where FV is the future value, P is the initial amount, PMT is the monthly contribution, r is the monthly rate of return, and n is the total number of months.

How to Use This Calculator

1. Enter your initial amount, monthly contribution, expected annual return, and time period.
2. Click Calculate to see the projected future value, total amount invested, and total growth.
3. Try different rates and time periods to see how compounding affects your results over the long run.

Tips for Getting Accurate Results

• Use a realistic, conservative rate of return rather than an optimistic best-case number.
• Remember that actual investment returns vary year to year; this calculator assumes a constant average rate.
• Increasing your monthly contribution, even slightly, tends to have a large impact over long time periods due to compounding.
