Frequently Asked Questions
How is compound interest different from simple interest?
Compound interest is calculated on the principal plus previously accumulated interest, while simple interest is calculated only on the original principal.
Does compounding frequency matter?
Yes — more frequent compounding (monthly vs annually) results in a higher final amount for the same nominal interest rate.
