Tips

  • Daily compounding yields slightly more than monthly or annual — the difference grows with higher rates and longer terms.
  • Early withdrawal penalties can significantly reduce your return. Always check your CD's penalty policy before locking in funds.
  • FDIC insures CD deposits up to $250,000 per depositor, per bank — spread large deposits across multiple institutions if needed.
About

A CD calculator helps you find the exact maturity value of a certificate of deposit before you commit your money. Enter your principal, APY, and term length — from 3 months to several years — and instantly see your total interest earned, effective annual yield, and a period-by-period growth schedule broken down by compounding frequency.

FAQ
What is a certificate of deposit (CD)?+

A CD is a savings product offered by banks and credit unions that holds a fixed sum of money for a set term — typically 3 months to 5 years — in exchange for a guaranteed interest rate. You agree not to withdraw the funds early (or pay a penalty if you do), and in return receive a higher rate than a standard savings account.

What is the difference between APR and APY for a CD?+

APR (Annual Percentage Rate) is the simple interest rate before compounding. APY (Annual Percentage Yield) reflects the actual return including the effect of compounding within the year. Banks advertise CDs using APY because it represents your true annual earnings. This calculator uses APY directly so the result matches what your bank quotes.

Does compounding frequency affect my CD earnings?+

Yes, though the difference is modest at typical CD rates. Daily compounding produces slightly more interest than monthly or annual compounding for the same APY, because interest is reinvested more often. On a $10,000 CD at 5% APY over 1 year, daily compounding earns a few cents more than annual compounding.

What happens if I withdraw my CD early?+

Most CDs charge an early withdrawal penalty — commonly 90 days of interest for terms under 1 year and 180 days or more for longer terms. This calculator shows the full-term maturity value only. If you may need the funds before maturity, consider a no-penalty CD or a high-yield savings account instead.
