Frequently Asked Questions (FAQ)
What is the difference between APY and interest rate? APY takes into account the effects of compound interest, while the interest rate is the nominal rate without considering compounding.
Can I use this calculator for different investment types? This calculator is specific to CDs but can also be applied to other interest-bearing accounts.
How does compounding frequency affect APY? The more frequently interest is compounded, the higher the APY, as the interest earned is reinvested more often.
