Frequently Asked Questions
How is CD interest calculated?
CD interest is calculated using compound interest based on the APY, the compounding frequency (daily, monthly, quarterly, or annually), and the term length. Most banks compound daily or monthly.
What happens if I withdraw early?
Most CDs charge an early withdrawal penalty, often equal to a few months of interest. This calculator assumes you hold the CD until maturity without early withdrawal.
Is APY the same as the interest rate?
No. APY reflects the effective annual return including compounding, while the stated interest rate does not account for compounding within the year.
