About the CD Calculator

This cd calculator is a simple cd interest calculator that shows how much your certificate of deposit could be worth at maturity. By entering your deposit, CD term and CD rate, the cd calculator estimates your CD interest, CD returns and final CD account value so you can compare different CD rates and terms before locking in your money.

1

Deposit amount and CD term

The cd calculator starts with your initial deposit and CD term. Whether you are opening a short-term 6 month CD or a longer 5 year CD account, the cd calculator uses the same compound interest formula to project your CD value.

2

CD rate and compounding

As a cd rate calculator, this tool lets you test different CD rates and compounding options like annual, monthly or daily. The cd calculator applies the chosen compounding frequency to your CD interest so you can see how CD rates and compounding change your CD returns.

3

Reinvest or pay out interest

Many banks offer CDs where interest is paid out monthly or reinvested. The cd account calculator lets you choose whether to compound interest or take it as cash, so you can compare simple interest with compounded CD returns in one cd calculator.

What affects your CD returns?

  • CD rate: higher CD rates mean your cd interest calculator results will show larger interest earnings over the same CD term.
  • Term length: longer CD terms give the cd calculator more time to grow your deposit, but may lock your money in for years.
  • Compounding: more frequent compounding (monthly or daily) can slightly boost cd return calculator results compared with annual compounding at the same stated CD rate.
  • Early withdrawal penalties: this cd calculator assumes you hold the CD to maturity. Cashing out early usually reduces your actual CD returns versus what the cd interest calculator shows.
