What Happens When You Withdraw From a CD Early?

Certificates of Deposit offer great rates because you agree to leave your money untouched for a fixed term. But if you need that cash early, the bank charges a penalty. It’s their way of saying, “We counted on this money being here.”

Here’s what the penalty typically looks like:

  • 3 months of interest — for CDs with terms of 12 months or less
  • 6 months of interest — for CDs longer than 12 months
  • Up to 12 months of interest — for some long-term CDs

The formula is simple: Penalty = (Deposit Amount × Interest Rate) ÷ 12 × Penalty Months

But the real question is: Is it worth it? Our calculator helps you answer that.


Real-World Example: See It in Action

Scenario: You deposited $10,000 in a 12-month CD at 4.50% interest. Six months in, an unexpected expense comes up. Your bank charges a 3-month penalty.

Variable Value
Deposit Amount $10,000
CD Term 12 months
Interest Rate 4.50%
When You Withdraw Month 6
Penalty Period 3 months
Interest Earned So Far $225.00
Penalty Amount $112.50
What You Walk Away With $10,112.50

You earned $225 in interest, forfeited $112.50 as a penalty, and still walked away with more than you started. Not bad—but it’s good to know the numbers before you make the call.

Common Questions About CD Early Withdrawal Penalties

What is a CD early withdrawal penalty?

It’s a fee the bank charges when you take money out of a CD before its maturity date. It’s usually calculated as a number of months’ worth of interest.

How is the penalty calculated?

It’s typically: (Deposit Amount × Interest Rate) ÷ 12 × Penalty Months. For example, a 3-month penalty on a $10,000 CD at 4.50% would be $112.50.

When does the penalty apply?

Any time you withdraw funds before your CD’s maturity date. Most banks offer a 7-to-10-day grace period after maturity where you can withdraw without a penalty.

What is the penalty period on a CD?

It’s the number of months of interest you forfeit: - CDs under 12 months — usually 3 months - CDs 12 months or longer — usually 6 months - Some longer-term CDs — up to 12 months

Can I avoid the penalty?

Yes, if you wait until the CD matures or withdraw during the grace period. Some banks also offer “no-penalty” CDs, though they typically have lower rates.

This calculator gives you a clear estimate, but your bank’s terms are the final word. Use it as your starting point to make a confident, informed decision.
