CD early-withdrawal penalties: how the cost is calculated
A CD early-withdrawal penalty is the bank's charge for taking principal out before maturity. On a $10,000 CD at 4.50% APY, a 3-month interest penalty is larger than the modeled interest earned after only 2 months.
How is a CD early-withdrawal penalty calculated?
There is no single penalty used by every bank. The agreement may charge 90 days of interest, 3 months of interest, a fixed $75, or another disclosed amount. The bank may apply that rule to the full deposit or only the amount withdrawn.
CFPB Regulation DD requires a time-account disclosure to state the early-withdrawal penalty and the conditions for charging it. It also permits month-based wording even when the bank converts the period to a set number of days. That is why a calculator can estimate the cost but cannot replace the bank's payoff quote.
How can a bank state the penalty?
| Disclosure wording | What it means for a $10,000 CD |
|---|---|
| 90 days of interest | The bank calculates interest for a 90-day period under its stated method. |
| 3 months of interest | The bank may use 3 calendar months or a disclosed day convention. |
| $75 | The fixed $75 comes straight out of the modeled account balance. |
| Interest earned to date | The penalty may be capped before it reaches the $10,000 principal. |
Bank terms differ sharply. In the American Express terms checked July 17, 2026, a CD shorter than 12 months carries a 90-day interest penalty, while a term from 12 months to under 48 months carries a 270-day penalty. Those terms can change, so check the current agreement.
What does an early withdrawal cost on $10,000?
Start with a $10,000 deposit, 4.50% APY, and a 12-month term. The example withdrawal happens after month 2, and the stated penalty is 3 months of interest.
| Modeled interest after 2 months | $73.63 |
|---|---|
| Estimated 3-month penalty | $110.65 |
| Estimated withdrawal proceeds | $9,962.98 |
| Modeled principal loss | $37.02 |
Waiting until month 6 changes the result. Modeled interest reaches $222.52, while the estimated penalty stays $110.65. The modeled proceeds rise to $10,111.87.
Can a CD penalty reduce principal?
Yes. In the month-2 example, the estimated penalty exceeds earned interest by $37.02. The modeled payout falls below the original $10,000 deposit.
The bank agreement controls this result. Ally's deposit agreement checked July 17, 2026 says an unpaid part of its penalty can be deducted from principal. Chase caps the listed personal CD penalties at interest earned during the current term, according to its agreement effective June 14, 2026. Do not assume one bank's cap applies to another bank.
Should you break a CD for a higher APY?
A higher rate is not enough by itself. Moving $10,000 from 4.00% APY to 4.50% APY for 6 months adds only about $24.48 under SaverGrid's model. That does not recover a$110.65 penalty.
Compare the payoff amount from the bank with the dollars you expect to earn elsewhere during the remaining term. And include any days when the money will sit between accounts. A 0.50 percentage-point rate gap can look bigger than it is.
Where do you find the bank's penalty rule?
- Open the Truth in Savings disclosure or deposit agreement for the CD.
- Find “early withdrawal,” “time account,” or “certificate penalty.”
- Check whether the rule uses 60 days, 3 months, a fixed dollar amount, or another formula.
- Ask the bank for a written payoff quote before closing the account.
A payoff quote is the better number. Use theSaverGrid penalty calculator to check the disclosure and see whether principal may be at risk.
