Frequently asked questions
- What is the difference between APR and APY?
- APR (Annual Percentage Rate) is the simple annual rate. APY (Annual Percentage Yield) accounts for compounding within the year, so it's always greater than or equal to APR. The more frequently interest compounds, the larger the gap.
- Why does compounding frequency matter?
- More frequent compounding means interest earns interest sooner. Daily compounding produces a higher APY than monthly compounding for the same APR.
