A = P \left(1 + \frac{r}{n}\right)^{n \times t}, \quad \text{Penalty} = P \times \left( \frac{r}{12} \right) \times m_{\text{penalty}}Calculates total future value by converting advertised APY to the nominal rate and applying frequency compounding periods, with early withdrawal forfeiture based on contractual penalty months.

APR (Annual Percentage Rate) is the simple contractual interest rate without compounding. APY (Annual Percentage Yield) reflects the true annual return you earn when interest compounds daily or monthly. Because interest compounds on previously earned interest, the APY is always slightly higher than the nominal APR.
Banks assess an Early Withdrawal Penalty if you break a CD before maturity. Typically, for terms of 12 months or less, the penalty is 3 months of simple interest. For terms over 12 months, penalties often equal 6 months of interest. Federal law requires at least 7 days of interest penalty.
A CD Ladder divides your savings across certificates with staggered maturity dates (e.g., 1-year, 2-year, 3-year, 4-year, and 5-year CDs). Each year, one CD matures, providing cash liquidity or the opportunity to reinvest at prevailing market rates without locking all your funds into a single term.
