What is a Certificate of Deposit (CD)?

A Certificate of Deposit (CD) is a savings product that earns interest on a lump sum for a fixed period of time. CDs differ from savings accounts because the money must remain untouched for the entire term (or you risk paying a penalty or losing interest). In exchange for this lack of liquidity, CDs usually pay higher interest rates.

How This Calculator Works

This tool calculates the future value of your CD using the compound interest formula.

  • Principal: The amount you deposit.
  • Term: How long you agree to leave the money in the bank.
  • APY vs. APR: Banks advertise APY (Annual Percentage Yield), which includes the effect of compounding. This calculator allows you to adjust the compounding frequency to match your bank's terms (Daily is best!).

CD Ladders: A Smart Strategy

Don't want to lock all your money up for 5 years? Consider a "CD Ladder."
Instead of putting $10,000 in one 5-year CD, you split it:

  • $2,000 in a 1-year CD
  • $2,000 in a 2-year CD
  • $2,000 in a 3-year CD
  • $2,000 in a 4-year CD
  • $2,000 in a 5-year CD

As each CD matures, you renew it into a new 5-year CD. This way, you have access to some of your cash every year while still taking advantage of longer-term rates.

Disclaimer & Legal Notice

Estimations Only: This calculator provides estimates assuming the interest rate remains fixed for the entire term.

Taxes: Interest earned on CDs is generally considered taxable income in the year it is earned, even if you don't withdraw it. The "Est. Tax" field helps you plan for this liability but is not a substitute for professional tax advice.

Early Withdrawal Penalties: This tool assumes you hold the CD until maturity. If you withdraw funds early, banks typically charge a penalty (e.g., 3 months of interest), which is not calculated here.
