See what a certificate of deposit will be worth at maturity — your ending balance and the total interest earned at a given APY.
APY already reflects compounding, so this uses annual compounding at the quoted yield. Early-withdrawal penalties and taxes on interest are not included. General information, not financial advice.
A certificate of deposit pays a fixed APY in exchange for locking your money up for a set term. Because the yield is guaranteed, the math is simple and certain — unlike investing, there's no market risk, but also no upside beyond the quoted rate.
Maturity = deposit × (1 + APY)ʸᵉᵃʳˢ
APY includes the effect of compounding, so it's the true annual return. CDs are quoted in APY, which is what this calculator uses.
Most CDs charge an early-withdrawal penalty — often several months of interest. Only lock up money you won't need before the term ends.
