CD Early Withdrawal Penalty, and How to Work Out What It Costs

A CD penalty is set by the bank's own terms, not by one federal number, so the cost of breaking a CD is whatever the account agreement says: usually a stated number of days or months of interest. The CFPB puts it plainly: withdrawing money early means paying a penalty fee to the bank, and when you compare CDs you should look at the term, the rate, and the size of that penalty. The math below turns a typical penalty into dollars.

1. What federal rules require the bank to tell you

Regulation DD, the Truth in Savings rule, requires a bank to disclose, for a time account, "a statement that a penalty will or may be imposed for early withdrawal, how it is calculated, and the conditions for its assessment." So the penalty formula has to be written down before you open the account.

The CFPB's official commentary lists what counts as a penalty:

• A flat dollar amount, such as $10.
• An amount of interest, such as "seven days' interest plus accrued but uncredited interest."
• A worse deal on money left in the account, such as a lower interest rate, a lower APY, or less frequent compounding.
• Taking back a sign-up bonus.

The commentary also allows a penalty to be stated in months. "One month's interest" is permitted whether the bank actually charges 28, 30, or 31 days, so two banks advertising the same words can differ by a few days of interest.

Regulation D sets only a floor. A deposit counts as a time deposit if withdrawals in the first six days after the deposit carry a penalty of at least seven days' simple interest. A bank can set a much larger penalty, and the example below uses one.

2. The worked example

Assumptions, kept simple on purpose: a $10,000 CD paying 4.00% a year, interest approximated as simple interest over a 365-day year, and a penalty of 180 days of interest on the amount withdrawn. Compounding and taxes are ignored.

• Interest per day: $10,000 x 0.04 / 365 = $1.0959
• Penalty: 180 x $1.0959 = $197.26 (1.97% of the deposit)

What leaving early does, depending on when you leave:

Two things stand out. First, the penalty is a fixed bite, so the earlier you leave, the worse it looks. After 6 months you have earned almost exactly what the penalty takes back. Second, even after a full year the net gain is $202.74, which is an annualized 2.03% instead of the advertised 4.00%.

The first row raises a question the table cannot answer: if the penalty is larger than the interest earned, where does the rest come from? The sources above do not say, and banks differ. The disclosure rule tells you how to find out: the account agreement must explain how the penalty is calculated and when it applies, so read that sentence before you deposit.

3. When breaking a CD for a better rate pays

Suppose you are tempted to move the money to an account paying more. The penalty is a one-time cost of 1.97% of the balance. The gain is the extra rate earned every year afterward. Ignoring compounding and taxes:

Break-even time in years = penalty as a percent of the balance / (new rate - old rate)

If your CD has only 8 months left, no realistic rate gap makes the move worth it. If it has four years left and a rate 1.5 points higher is available, it might. The remaining term matters as much as the rate.

One more cost to account for: the replacement account must actually hold the higher rate for the whole break-even period. A variable savings rate that drops after a few months can erase the gain.

4. What else changes when you take money out early

Regulation DD also requires a disclosure when interest can be withdrawn before maturity. If interest compounds during the term and you take it out, the bank must state that the APY assumes interest stays on deposit and that a withdrawal will reduce earnings. Pulling interest out each month therefore lowers what you end up with compared with the advertised APY.

Interest is taxable income in the year it becomes available to you. The IRS notes that interest on CDs is taxable and that you should receive a Form 1099-INT if payments total $10 or more. Early withdrawal does not make that earned interest disappear from your return.

5. Questions to answer before you open a CD

1. How is the penalty calculated: days, months, or a percentage of interest?
2. Does it apply to the amount withdrawn or to the whole balance?
3. Can it reach principal if interest earned is smaller than the penalty?
4. Is there a grace period after maturity, and does the CD renew automatically?
5. Does the penalty change if you take out only part of the balance?

6. Key takeaways

• Penalties are set by each bank, but Regulation DD requires the bank to disclose how the penalty is calculated and when it applies.
• A fixed penalty of 180 days of interest on a 4.00% CD costs about $197 per $10,000.
• Leaving a CD at 3 months can mean a net loss, at 6 months about break-even, and at 12 months a 2.03% annualized return in this example.
• Break-even time for switching equals the penalty percentage divided by the rate gap, so a 1-point gap pays back a 1.97% penalty in about 2 years.
• Read the account agreement for whether a penalty can exceed earned interest. This page does not know your bank's terms.
