Frequently Asked Questions

How is CD interest calculated?

Most CDs compound interest daily or monthly and credit it to your balance; this calculator uses quarterly compounding as a close approximation for most standard CDs.

What happens if I withdraw early from a CD?

Early withdrawal typically triggers a penalty, often equal to several months of interest — check your specific CD's terms.
