CD Calculator | Certificate of Deposit Interest & Maturity

Yes, standard CDs have fixed interest rates for the entire term, guaranteeing your return regardless of market changes. This makes them low-risk, FDIC-insured savings vehicles ideal for money you won't need until maturity.

Most banks charge an early withdrawal penalty, typically 3-6 months of interest for short terms and 6-12 months for longer terms. Use the Early Withdrawal Penalty mode in this calculator to see the net interest after penalties and whether breaking the CD makes financial sense.

A CD ladder spreads money across multiple CDs with staggered maturity dates (e.g., 1-year, 2-year, 3-year). When each CD matures, you reinvest at current rates. This gives you regular access to funds while capturing higher long-term rates. Use the CD Ladder mode to model a multi-rung strategy.

Use Compare mode to enter up to three CDs with different APY rates and terms side by side. The calculator shows maturity value, total interest earned, and effective yield for each so you can identify the best offer for your timeframe.
