Compound Interest FAQs

What is compound interest?

Compound interest is interest calculated on both the initial principal and accumulated interest from previous periods. It's "interest on interest" that grows your money faster.

Does compounding frequency really matter?

Yes! On $10,000 at 5% for 10 years: annual compounding gives $16,289, daily gives $16,487. That's an extra $198 just from more frequent compounding.

What is the compound interest formula?

A = P(1 + r/n)^(nt) where A = final amount, P = principal, r = annual rate, n = compounding frequency, t = time in years.

Is daily compounding better than monthly?

Yes, daily compounding earns slightly more than monthly. However, the difference diminishes as frequency increases. Daily vs monthly might only differ by 0.01-0.02% APY.

What is APY and how does it relate to compounding?

APY (Annual Percentage Yield) shows the actual annual return including compounding effects. It's always higher than the nominal rate when compounding occurs more than annually.
