Detailed explanation-1: -You can calculate the simple interest you’ll earn in a savings account by multiplying the account balance by the interest rate by the time period the money is in the account. Note that the interest in a savings account is money you earn, not money you pay. Here’s the simple interest formula: Interest = P x R x T.
Detailed explanation-2: -How Compound Interest Works. Compound interest is calculated by multiplying the initial principal amount by one plus the annual interest rate raised to the number of compound periods minus one.
