Effective APY

APR vs APY on a CD

Banks usually advertise CDs by their APY — what you'd earn over a full year including compounding. The "rate" you enter here is the nominal annual rate; the calculator computes the effective APY based on the compounding frequency you pick.

Early withdrawal penalty

If you cash out a CD before maturity, banks typically charge a penalty equal to 3–6 months of interest. Build that into your decision before locking up money you might need.
