CD Calculator (Certificate of Deposit)
Calculate the maturity value and interest earned on a Certificate of Deposit.
How Certificates of Deposit Work
A Certificate of Deposit (CD) is a savings product that pays a fixed interest rate for a fixed term. The formula is: A = P × (1 + r/n)^(n×t), where P is the deposit amount, r is the annual interest rate, n is the compounding frequency per year, and t is the term in years. The APY (Annual Percentage Yield) reflects the effective annual rate including compounding. Early withdrawal typically incurs a penalty (commonly 90-180 days of interest).
