See your CD's value at maturity and the effective annual yield.
A certificate of deposit (CD) calculator shows what your CD will be worth at maturity and its effective annual yield (APY). Enter your deposit, rate, term, and compounding frequency to see exactly how much interest you'll earn.
A certificate of deposit locks in a fixed rate for a set term in exchange for leaving your money untouched until maturity. Because the rate is guaranteed and (at U.S. banks) deposits are FDIC-insured up to limits, CDs are among the safest places to earn interest, the trade-off is access, since withdrawing early usually costs a penalty of several months' interest.
To keep some money accessible while still earning CD rates, many savers build a ladder, splitting the deposit across CDs that mature at staggered intervals so a portion comes due regularly. It's also worth shopping around: online banks and credit unions often pay noticeably more than large national banks. Compare offers by APY, which already reflects compounding.
It depends on the deposit, rate, term, and compounding. Enter them above to see the maturity value and interest earned.
APR is the stated rate; APY reflects the effect of compounding and is the true yearly yield. Banks quote CDs in APY.
Usually yes until maturity, withdrawing early typically triggers a penalty. This estimate assumes you hold to maturity.
