CD early withdrawal penalty calculator
Breaking a certificate of deposit (CD) before it reaches maturity often requires an early withdrawal penalty, but figuring out what that penalty costs isn’t always straightforward. Your bank or credit union may describe the penalty in terms of days or months of interest, for example, while you want to know the actual dollar amount.
Our CD early withdrawal penalty calculator uses the terms for your CD to estimate the potential penalty and what you could receive after paying it. Enter the information from your account disclosure to see how the penalty could affect your money.
Keep in mind that this is an estimate. Early withdrawal penalties can vary by financial institution and account, so your CD agreement and account disclosure control the actual charge.
CD Early Withdrawal Penalty Calculator
Estimate what it costs to cash out your CD before maturity.
(Penalty + Future Interest Missed)
Calculation Methodology: This calculator estimates the cost of cashing out a CD before maturity using your Deposit Amount, APY, CD Term, Time Remaining, and Penalty Type. It converts APY to an interest rate with daily compounding, projects your balance if you withdraw now versus at maturity, and applies the penalty as months of interest, days of interest, a percent of deposit, or a fixed fee. Interest-based penalties use simple interest; balances use daily compounding. Results show the Estimated Early Withdrawal Penalty, balances, Future Interest Missed, and Total Cost of Early Withdrawal. Actual bank charges may differ based on your CD agreement and compounding rules.

How to use the CD early withdrawal penalty calculator
Use this calculator to estimate what it may cost to cash out a CD before maturity. Enter your CD details on the left, and your results update automatically as you adjust each field—no calculate button needed.
Step 1: Enter your deposit amount
Add the amount currently in your CD. Use the balance shown on your statement or account details so the penalty and projected balances are based on your actual deposit.
Step 2: Enter your annual percentage yield (APY)
Enter the APY listed in your CD agreement or account summary. The calculator converts this APY into an interest rate assuming daily compounding to estimate interest earned and interest-based penalties.
Step 3: Set your CD term
Enter the full length of your CD and choose Months or Years. For example, enter 12 with Months selected for a 1-year CD, or 5 with Years selected for a 5-year CD.
Step 4: Enter time remaining for CD maturity
Enter how much time is left until your CD matures. This helps the calculator estimate interest already earned, interest you would miss by withdrawing early, and your balance if you keep the CD to maturity.
Step 5: Choose your penalty type
Select the penalty format listed in your CD agreement: Months of Interest, Days of Interest, % of Deposit, or Fixed Fee. Banks word these differently, so match the option to what your disclosure says. Tip: 3 months of interest is not the same as 90 days of interest—use the format your bank lists.
Step 6: Enter the penalty amount
After you choose a Penalty Type, enter the matching value—for example, 3 months, 90 days, 1% of deposit, or a $50 fixed fee. Use the info icon next to the field if you need a quick explanation of what to enter.
Step 7: Review your results
Once your inputs are entered, the calculator instantly shows:
- Estimated Early Withdrawal Penalty — the projected fee for cashing out early
- Balance if you withdraw now — what you may receive after the penalty
- Balance if kept to maturity — what your CD may be worth if you wait
- Future Interest Missed — interest you give up by withdrawing early
- Total Cost of Early Withdrawal — penalty plus missed future interest
Adjust any field to compare scenarios—such as waiting longer or using a different penalty type—and see how the cost of early withdrawal changes.
How CD early withdrawal penalties are calculated
Early withdrawal penalties on CDs are often calculated by forfeiting a specific number of days or months of interest based on the CD’s terms. The exact calculation depends on the terms of your CD, so it’s important to check your account disclosure before entering your information into the calculator.
For an interest-based penalty, a simplified calculation looks like this:
Penalty = amount subject to penalty × annual interest rate × penalty period
The interest rate used to calculate an early withdrawal penalty isn’t necessarily the same as the CD’s annual percentage yield (APY). APY reflects the effects of compounding, while the stated interest rate may be used to calculate an interest-based penalty. Check your CD disclosure for the rate and calculation method that apply to your account.
For example, if your CD applies a penalty based on 90 days of interest, the calculator can estimate the penalty using the annual interest rate and a fraction of a year. For a daily calculation, that may look like:
Penalty = amount × annual interest rate ÷ 365 × penalty days
This provides an estimate based on the information you enter. Your financial institution may use a different calculation method or day-count convention, however, so the amount charged could differ.
Penalty stated in days of interest
Some CD disclosures state the early withdrawal penalty as a specific number of days of interest. If your disclosure says the penalty is 90 days of interest, for example, the calculator can use 90 days as the penalty period.
The calculator may use a daily simple interest estimate based on 365 days a year. Your bank or credit union may use a different method if its account terms specify one, so check your disclosure before relying on the estimate.
Penalty stated in months of interest
A CD penalty may also be expressed as a certain number of months of interest. If your disclosure says you would pay six months of interest for an early withdrawal, for example, you can enter that penalty period into the calculator.
Don’t assume a month always equals exactly 30 days. Financial institutions may use different methods when applying a penalty stated in months, depending on the terms of the account.
When the bank uses a different penalty method
Not every early withdrawal penalty is based on a simple interest calculation. Your CD could have a flat-dollar penalty, a different rate or calculation method, or terms that require you to give up a portion of your earnings. Some accounts may also have other conditions that affect the amount you receive when you withdraw early.
If your CD uses a method that isn’t supported by the calculator, use the penalty terms in your account disclosure or contact your financial institution to determine the actual charge. The calculator is intended to provide an estimate to help you compare the penalty with projected CD earnings. However, it does not replace the terms of your CD.
Example: Estimating the cost of breaking a CD early
Imagine you have $10,000 in CD principal subject to the penalty, a 4.00% stated annual interest rate, and an early withdrawal penalty of 180 days of interest. Using a simplified daily-interest calculation, the estimated penalty would be:
$10,000 × 0.04 ÷ 365 × 180 = $197.26
In this illustrative example, the estimated early withdrawal penalty would be $197.26. This amount is an estimate based on the assumptions above and does not represent a current or typical CD penalty.
The actual amount you pay could be different if your bank or credit union uses a different calculation method or day-count convention. To estimate your own cost, enter the penalty language and other terms from your CD agreement into the calculator.

How to interpret the result before you withdraw
Once you know your estimated early withdrawal penalty, there’s more to consider than the actual penalty amount. Comparing a few numbers can help you understand the potential cost of accessing your money before the CD matures.
Start by comparing the estimated penalty with the interest you’ve already earned and the interest you could earn by leaving the money in the CD until maturity. This can give you a clearer picture of the trade-off involved in withdrawing early.
If you’re considering moving your money to a CD or savings account with a higher rate, compare the potential earnings over the remaining time on your current CD after accounting for the estimated penalty. Looking at APYs alone doesn’t show the full financial impact of breaking the CD early.
If you need the money for another reason, the estimated penalty can help you understand the potential cost of accessing your money now. You can then weigh that cost against the reason you need the funds and the alternatives available to you.
When you’re unsure how your penalty applies, contact your bank or credit union before making a withdrawal. This is especially important if you’re considering a partial withdrawal, recently opened the CD, received a promotional rate, or have a callable CD. You should also check with the institution if the penalty involves something other than giving up interest.
Why your bank’s actual penalty may differ from the estimate
Your bank or credit union may calculate an early withdrawal penalty differently from the simplified method our calculator uses. Ultimately, your CD agreement and account disclosure control how your penalty is calculated and when it applies.
For example, a penalty stated as a certain number of months of interest doesn’t necessarily mean each month will be treated as exactly 30 days. The financial institution may use actual calendar days or another calculation method described in its account terms.
Other factors can also affect the amount you’re charged. These may include rules for partial withdrawals, flat-dollar fees, promotional bonuses, rate changes, or other terms specific to your CD.
For these reasons, treat the calculator result as an estimate only. Before authorizing an early withdrawal, check your account disclosure and contact your bank or credit union if you’re unsure how the penalty applies or want to confirm the final amount.
If you want more flexibility with your savings in the future, you could also consider a no-penalty CD. These CDs aren’t offered by every bank and may have fewer term options, but they typically let you withdraw your money before maturity without an early withdrawal penalty, subject to the account terms.
Frequently asked questions
Check your CD agreement, account disclosure, or other documents provided by your bank or credit union when you opened the account. You can also contact the financial institution directly if you can’t find the penalty terms or need help understanding them.
No. Financial institutions may express early withdrawal penalties in days or months of interest or use another calculation method outlined in the account terms.
Enter the amount subject to the penalty, the applicable annual interest rate, and the number of penalty days into the calculator. The calculator uses those inputs to estimate the interest-based penalty, but your institution may use a different calculation method.
You may be able to use the calculator if your CD’s terms specify how a partial withdrawal penalty is calculated and the calculator supports the necessary inputs. Check with your bank or credit union first, since partial withdrawal rules vary by account.
