Applications
Essential for comparing savings accounts, CDs, and investment products. It reflects the real rate of return better than the nominal APR.
Compounding Formula
APY = (1 + r/n)^n - 1, where 'r' is the nominal annual interest rate and 'n' is the number of compounding periods per year.
Fun Fact: Compounding is often called the '8th wonder of the world.' Even small differences in APY can lead to huge wealth differences over decades!
