CD (Certificate of Deposit) Calculator
Work out what a CD or fixed-term deposit will earn at a given rate and term.
How a CD works
You lock money for a fixed term and earn a fixed rate. Because the rate is guaranteed, it suits money you know you will not need soon. Early withdrawal usually triggers a penalty.
Laddering
A CD ladder splits money across different terms so some matures regularly, giving access and a chance to reinvest at new rates.
