Frequently Asked Questions
APY stands for Annual Percentage Yield. It reflects the total amount of interest earned on a deposit account over one year, taking into account the effect of compounding.
More frequent compounding results in a higher APY because interest is earned on interest more often. For example, daily compounding yields a slightly higher APY than monthly compounding at the same nominal rate.
No. APY includes the effect of compounding, while APR (Annual Percentage Rate) does not. APY is typically higher than APR for the same nominal rate.
