CD Calculator

This calculator compounds a certificate of deposit forward to its maturity date. Enter the deposit, the APY your bank quotes and the term in months to get the value at maturity and the interest earned. A second tab starts from a nominal interest rate and a compounding frequency instead, and converts it to an effective annual yield first. Rates are the ones you type in, not live bank rates, and the result ignores tax and any penalty for withdrawing early, so read it as an estimate.
