What is the CD Calculator?
Calculate an estimated CD maturity value using the annual percentage yield and term you enter. The result uses APY as the effective annual yield.
Because APY already reflects compounding over one year, the calculator applies the effective yield over the selected fractional-year term.
Formula and calculation method
Maturity value = Deposit × (1 + APY)^(term months ÷ 12).
The result uses only the values entered on this page. It does not fetch account balances, market prices, tax returns or provider quotes.
Important limitations
Financial projections simplify real life. Returns can vary, laws and limits can change, inflation is uncertain, and taxes or fees may apply. Review the result as a scenario—not a promise.
Financial scope: Educational estimates only; not financial, investment, tax, legal or insurance advice.
