CDs vs The Stock Market: Risk and Reward

When utilizing a CD calculator, you are running the math on the safest investment vehicle available to consumers. A Certificate of Deposit offers a guaranteed rate of return, unlike the stock market which can crash right when you need the money.

When to use a CD

  • You are saving a down payment for a house you plan to buy in 1 or 2 years.
  • You are retired and need guaranteed income streams to pay for living expenses (this is called building a "CD Ladder").
  • You have zero tolerance for market volatility.

When NOT to use a CD

  • This is money for your retirement 30 years from now (the stock market will easily beat CD rates over a 30-year span).
  • This is your primary Emergency Fund (if you need the money tomorrow for a hospital bill, the bank will charge you an early withdrawal penalty to break the CD).

What is a CD Ladder?

One problem with a 5-year CD is that your money is trapped for 5 years. If interest rates suddenly soar to 8%, you are still stuck earning the 4% you locked in years ago. Investors solve this using a CD Ladder.

Instead of putting $50,000 into one 5-year CD, you split it into 5 chunks of $10,000. You put chunk 1 into a 1-year CD, chunk 2 into a 2-year CD, chunk 3 into a 3-year CD, etc.

Now, every single year, one of your CDs matures. You collect the guaranteed interest, and if you don't need the cash, you reinvest that $10,000 into a brand new 5-year CD. This gives you high interest rates while ensuring you have access to a chunk of cash every 12 months.

Bank CD Questions

A CD is a type of savings account offered by banks and credit unions that holds a fixed amount of money for a fixed period of time (the 'term'), such as six months, one year, or five years. In exchange, the bank pays a higher, guaranteed interest rate than a standard savings account.
Yes, but you will usually pay an 'early withdrawal penalty.' This penalty is often equal to several months of interest earned. Because of this, you should only put money into a CD that you are absolutely certain you won't need until the term ends.
Yes. CDs (in the United States) are insured by the FDIC up to $250,000 per depositor. Even if the stock market crashes 50% or the bank goes bankrupt, your principal and the guaranteed interest you locked in are protected by the federal government.
An HYSA allows you to deposit and withdraw money freely, but the interest rate is variable (it can drop tomorrow). A CD locks your money up, but the interest rate is fixed (it cannot drop) for the entire duration of the term.
Most CDs compound interest daily and credit it to your account monthly. However, some compound monthly, quarterly, or even annually. Daily compounding yields a slightly higher final payout on the exact same nominal rate.
