Standard US Banking Protection Insured up to $250,000
CDs issued by FDIC-insured member banks or NCUA-insured credit unions guarantee your principal and accrued interest up to $250,000 per depositor. Calculations assume fixed APY rates held to maturity.
How Certificate of Deposit Calculations Work
American banks quote yields in APY (Annual Percentage Yield), which accounts for compounding frequency over 365 days.
You place an initial principal (e.g. $5,000, $10,000, or $50,000) with an FDIC-insured institution for a set term.
Most top US banks compound interest daily and credit it to your account monthly, accelerating exponential growth.
When the term ends, you receive full principal plus earned interest, with a 7 to 10 day grace period for renewal or payout.
