About the CD Calculator
A certificate of deposit (CD) locks your money in for a fixed term at a guaranteed rate. Enter your deposit, the interest rate, the term in years, and the compounding frequency to see the value at maturity and the interest earned. Use it to compare CD offers or decide whether a longer term's higher rate is worth locking your cash away.

Frequently asked questions
How is CD interest calculated?
The deposit compounds at the CD's rate for the term. This tool uses your rate and compounding frequency to show the maturity value.
APY vs interest rate?
APY already includes compounding, so it's the true annual yield. If you have the APY, set compounds per year to 1 and enter the APY as the rate.
Is there a penalty for early withdrawal?
Usually yes — cashing out a CD before maturity forfeits some interest. Only deposit money you won't need during the term.
