Frequently Asked Questions
A bank certificate of deposit (CD) is a time deposit offered by banks with a fixed term and interest rate.
The future value is calculated using the compound interest formula: A = P (1 + r/n)^(nt), where P is principal, r is annual interest rate (decimal), n is compounding periods per year, and t is term in years.
Compounding frequency refers to how often interest is added to the principal. Common frequencies include annually, semiannually, quarterly, monthly, and daily.
