Free CD Calculator

Calculate the maturity value of a certificate of deposit.

APY already reflects compounding, so it's the number to compare across banks — a 5% APY CD compounded monthly will out-earn a 5% APY CD compounded annually is not correct, since APY normalizes for that. Compounding frequency mainly matters when you're comparing a stated interest rate rather than APY.
