CD Early Withdrawal Penalty Calculator
Estimate what you could receive after closing a fixed-rate CD before maturity. Enter the penalty as your bank states it: months, weeks, or days of interest, or a fixed dollar amount.
Bank account terms control the actual penalty. This calculator models a full withdrawal and does not cover partial withdrawals, bonus reclamation, rate changes, fees, taxes, IRA penalties, or exceptions and waivers.
Estimate for a full withdrawal after month 6. Bank calculations may use the nominal rate, actual days, or other disclosed rules.
| Original deposit | $10,000.00 |
|---|---|
| Modeled interest through withdrawal | $222.52 |
| Modeled balance before penalty | $10,222.52 |
| Applied early-withdrawal penalty | −$110.65 |
| Estimated withdrawal proceeds | $10,111.87 |
| Estimated value if held to maturity | $10,450.00 |
| Difference versus holding to maturity | $338.13 |
Modeled interest first covers the full stated penalty at month 3.
Should you break this CD?
Breaking a CD only pays off if the money can earn enough somewhere else to make up the penalty. Enter the APY you could actually get today, and both options are compared on the same date: your original maturity, 6 months from the withdrawal.
Holding wins by $88.42. At 5.00% the replacement account does not recover the $110.65 penalty.
Break-even APY: 6.80%. A replacement account has to beat that rate before breaking this CD is worth it.
| Option | Starting amount | Value at original maturity |
|---|---|---|
| Hold to maturity | $10,000.00 already on deposit | $10,450.00 |
| Withdraw and reinvest at 5.00% | $10,111.87 after penalty | $10,361.58 |
This compares rates only. It ignores taxes, the fact that a penalty may be deductible, fees on the new account, and any need for the cash itself. Moving money for liquidity can be the right call even when the arithmetic says hold.

This is SaverGrid's equivalent-APY estimate. Use the amount supplied by your bank when its disclosure uses a different formula.
How the estimate works
SaverGrid first estimates the CD balance at the withdrawal month. For a penalty stated in months, weeks, or days of interest, it applies the APY-equivalent growth for that penalty period to the original deposit. A fixed-dollar penalty is subtracted directly.
Your bank may use its nominal interest rate, actual calendar days, or another method in the account agreement. Regulation DD requires time-account disclosures to state whether an early-withdrawal penalty may apply, how it is calculated, and the conditions for assessing it. Copy the terms from that disclosure and confirm the payoff amount with the bank before withdrawing.
Reading the results
- Withdrawal proceeds are the modeled balance minus the applied penalty.
- Principal loss appears when the penalty exceeds modeled interest earned.
- Difference versus maturity includes both the penalty and modeled future interest not earned after withdrawal, before the money is moved anywhere else.
- Break-even APY is the rate a replacement account has to beat for withdrawing to leave you ahead.
Deciding whether to break the CD
The penalty on its own does not answer the question people actually have, which is whether to move the money. That depends on what the money would earn next. Withdrawing costs you the penalty plus the interest the CD would have paid over its remaining term, and a new account has to cover both before you come out ahead.
The calculator handles that comparison directly. Enter the APY you could realistically get today and it values both choices on the same date, your original maturity, so you are not comparing a three-year outcome against a one-year one. The break-even APY is the useful number to take shopping: any account below it loses to simply leaving the CD alone.
Two things the arithmetic cannot decide for you. A penalty may be deductible on your federal return, which softens the cost, and the IRS treats it separately from the interest itself. And needing the cash is a perfectly good reason to withdraw even when holding would earn more. See the methodology for the complete formulas, limitations, and regulatory source.
Frequently asked questions
Can a CD early-withdrawal penalty reduce principal?
It can if the account agreement allows a penalty larger than the interest earned before withdrawal. Select the earned-interest cap only when the bank’s disclosure says that limit applies.
Why can the bank’s penalty differ from this estimate?
Banks may calculate a stated number of days or months of interest using the nominal interest rate, actual days, a fixed convention, or another disclosed method. SaverGrid uses an equivalent-APY estimate.
What does the break-even month mean?
It is the first modeled month when accumulated CD interest is enough to cover the full stated penalty. It does not mean withdrawing is better than holding the CD to maturity.
Does this include taxes or IRA penalties?
No. Results are pre-tax and do not include separate tax consequences or penalties that may apply to retirement accounts.
Is it worth breaking a CD to chase a higher rate?
Only when the new account pays enough to recover the penalty over the time left on the original term. Enter the rate you could actually get and the calculator compares both options on the original maturity date.
What is the break-even APY?
It is the lowest APY a replacement account must pay for breaking the CD to leave you no worse off. Beat that rate and withdrawing wins; fall short of it and holding wins. It rises with the size of the penalty and falls as the remaining term gets longer.
