What is a Certificate of Deposit?
A Certificate of Deposit (CD) is a type of savings account with a fixed interest rate and a fixed date of withdrawal, known as the maturity date. CDs typically offer higher interest rates than regular savings accounts because your money is locked in for the term.
Guaranteed Returns
Unlike stocks or mutual funds, a CD provides a mathematically guaranteed return. You know exactly what your balance will be on the maturity date.
CD Growth Formula
A = P(1 + r/n)^(nt)Where A is the final balance, P is the initial deposit, r is the annual percentage yield (APY) as a decimal, n is the number of compounding periods per year, and t is the time in years.
Investment Scenarios
Standard CD
A $10,000 deposit in a 12-month CD with a 5% APY compounding daily will earn $512.67 in interest by maturity.
Long-Term Security
Locking $25,000 in a 5-year CD at 4.5% APY guarantees exactly $6,307 of interest earned over the term, regardless of market drops.
