3.5 Compound Interest Formula

What is Compound Interest? Compound interest is interest that is compounded at certain intervals or earned continuously (all the time). Annually: A = P(1.

What is Interest? Interest is the amount earned on an investment or an account. Annually: A = P(1 + r) t P = principal amount (the initial amount you borrow.
