This CD calculator estimates certificate-of-deposit growth from a one-time deposit, annual rate, term length, and compounding frequency. It also includes an early-withdrawal penalty estimate so users can compare maturity value with a penalty-adjusted outcome when evaluating short-term savings choices.
Formula and method
The calculator compounds a one-time CD deposit across the selected term, then estimates an early-withdrawal penalty as a number of months of interest based on the entered annual rate.
Example
If a CD starts with 10,000, earns 4.75% annually, compounds monthly for 18 months, and has a 3-month interest penalty for early withdrawal, the calculator estimates both maturity value and the penalty-adjusted outcome.
