What is Certificate of deposit (CD)?

A savings product that locks money at a fixed rate for a set term.

Last updated

A CD is a time deposit: you commit money for a set period (three months to five years or longer) in exchange for a fixed interest rate — usually a bit higher than a plain savings account.

Withdraw early and you'll typically pay a penalty of several months' interest. CDs work well for money you know you won't need until a specific date, like a down payment.

What is a CD ladder?

Splitting money across CDs of different terms (say 1, 2, 3, 4, 5 years). As each matures you reinvest into a new 5-year CD — smoothing out rate changes and keeping some cash accessible each year.
