Frequently asked questions

Rate vs APY?

The rate is the nominal interest; APY includes compounding and is the real return. Compare CDs by APY.

What if I withdraw early?

CDs usually charge an early-withdrawal penalty, often several months of interest. This tool assumes you hold to maturity.

Are CDs safe?

In the US, bank CDs are FDIC-insured up to limits, making them very low risk.
