How CD Interest Rates Work

CD accounts are time-deposit accounts offered by banks and credit unions. They offer higher interest rates than regular savings accounts in exchange for a fixed term (usually 3 months to 5 years).

The interest rate on a CD is typically fixed for the duration of the term. When the term ends, you can either renew the CD or withdraw the funds, which may incur penalties if done early.

CDs are FDIC-insured up to $250,000 per depositor, per institution, for each account ownership category.

Understanding Compound Interest

Compound interest means that interest is calculated on the initial principal and also on the accumulated interest of previous periods. This can significantly increase your returns over time.

The formula for compound interest is:

A = P(1 + r/n)^(nt)

Where:

A = the future value of the investment/loan, including interest
P = the principal investment amount
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per year
t = the time the money is invested or borrowed for, in years

For example, if you deposit $1,000 at 2% annual interest compounded monthly for 1 year, your future value would be approximately $1,018.18.
