The early-withdrawal penalty is the clause that decides what a certificate of deposit actually earns you, and it is the clause almost nobody prices before signing. Rates differ between banks by tenths of a point. Penalties differ by hundreds of dollars on the same balance, and at some institutions they can take principal.
This page prices the penalty properly: where it comes from, the three shapes it takes, what each costs month by month on round numbers, and the two things that soften it — one from the tax code and one from the way bank failures are handled. It prints no bank's rate and names no bank, for the reasons on the hub page for this cluster.
Where the penalty comes from
The penalty is a term of your contract with the bank, not a rule of law — with one exception at the bottom.
The legal floor. Regulation D, which defines what counts as a time deposit, requires that money withdrawn within the first six days of deposit carry a penalty of at least seven days' simple interest. That is the entire legal minimum, and it is tiny. Everything above it is the institution's choice. The regulation also lists circumstances in which a bank may waive the penalty without the account ceasing to be a certificate — including the depositor's death or legal incompetence, and withdrawals within ten days after the maturity date of an automatically renewing certificate — and banks may choose to waive it in others, such as a court order or a required minimum distribution from a retirement certificate. Read the waiver list in your own terms; it is short and worth knowing.
The disclosure rule. Truth in Savings — Regulation DD — requires the bank to tell you, before you open the account, "that a penalty will or may be imposed for early withdrawal, how it is calculated, and the conditions for its assessment." The clause is always findable. If it is not, that tells you something about the institution before it tells you anything about the penalty.
The three shapes the penalty takes
Published schedules at three large online banks in September 2026 used three different structures for the same event. None of the three is unusual; between them they cover most of what you will see.
Shape 1: days of interest, in bands that widen with the term. Thirty days' interest on the shortest certificates, rising through 60, 90 and 120 days to 150 days on terms of four years and longer. The penalty is taken first from accrued interest, and then — the clause to underline — "if necessary, the principal". Partial withdrawals are not allowed: leaving means closing the certificate.
Shape 2: months of interest, in two bands. Three months' interest on certificates of a year or less; six months' on anything longer. Simple to read, and steep on short terms: three months is a quarter of a one-year certificate's total interest and half of a six-month certificate's.
Shape 3: days of simple interest on the amount withdrawn. Ninety days for terms up to two years, 180 days beyond. Two features of the wording matter. Simple interest, not compounded, so the penalty is calculated on the principal alone. And on the amount withdrawn, which implies partial withdrawals are possible with the penalty scaled to the part you take. This institution also lets you have interest paid out monthly, which means interest already paid to you is not at risk — only a withdrawal of principal is a penalty event.
The point of listing them is not that one is better. It is that the same phrase — "an early withdrawal penalty applies" — can mean a month's interest or half a year's, on the part you withdraw or the whole balance, from interest only or from your principal. The rate table does not show any of that.
What each penalty costs, month by month
$10,000 in a certificate at an illustrative 4.00%, which earns $400 over a year. The penalty, and the month at which the certificate has earned enough interest to cover it:
| Penalty | Cost on $10,000 at 4.00% | Interest covers it after |
|---|---|---|
| 30 days | $32.88 | about 1 month |
| 60 days | $65.75 | about 2 months |
| 90 days / 3 months | $98.63 | about 3 months |
| 120 days | $131.51 | about 4 months |
| 150 days | $164.38 | about 5 months |
| 180 days / 6 months | $197.26 | about 6 months |
| 270 days | $295.89 | about 9 months |
| 365 days | $400.00 | 12 months |
The right-hand column is the one to remember. Leave before that month and the penalty exceeds everything the certificate has earned. At an institution that deducts from interest first and then principal, that is the moment your principal is touched: a 90-day penalty on a certificate opened six weeks ago has $46 of interest to absorb it and takes about $53 from your deposit. At an institution that caps the penalty at interest earned, you get back your principal and nothing else. The schedule tells you which kind you have; read that line before the rate.
The exit, priced on a one-year certificate
The same $10,000 at 4.00% in a twelve-month certificate with a 90-day penalty, leaving early:
| Leave at | Interest earned | Net after penalty | Annualised return on the months held |
|---|---|---|---|
| Month 3 | $100.00 | $1.37 | 0.05% |
| Month 5 | $166.67 | $68.04 | 1.63% |
| Month 8 | $266.67 | $168.04 | 2.52% |
| Month 11 | $366.67 | $268.04 | 2.92% |
Even at month eleven, the exit costs a quarter of the year's interest and the money earned less than a savings account would have paid. At month three it earned nothing at all. This is why the one-year page says to buy the date, not the rate, and why the six-month page treats a short certificate as the wrong home for uncertain money: on a six-month term, a 90-day penalty is half the total interest.
Two things that soften the penalty
The tax deduction
A forfeited early-withdrawal penalty is deductible from gross income, and you do not need to itemise to take it. The bank reports it in Box 2 of your Form 1099-INT — the instructions tell the bank to enter "interest or principal forfeited because of an early withdrawal of time deposits, such as an early withdrawal from a certificate of deposit" — and you enter it on Schedule 1 of Form 1040 under adjustments to income, on the line labelled Penalty on early withdrawal of savings. The interest in Box 1 is reported in full, without subtracting the penalty; the penalty is then deducted separately, and it can be deducted even if it is larger than the interest you earned.
On the $98.63 penalty above, a saver at an illustrative 22% marginal rate saves $21.70 in tax, so the penalty's true cost is $76.93. That does not make an early exit cheap. It does mean the comparison between exiting and staying should be made after tax, and that the penalty is less punishing than the sticker suggests — which is more than can be said for most fees. How withholding and refunds interact with adjustments like this one is on the withholding page; the specifics of your return are your tax preparer's.
The bank failing
If your bank fails and another bank takes over its deposits, the FDIC's guidance in past failures has been that you may withdraw from any transferred account without an early-withdrawal penalty until you enter into a new deposit agreement with the acquiring bank — which may, for its part, change the rate on what it acquired. A certificate whose rate is cut by a new owner is one you can leave for free. The insurance page covers the rest of what happens on that day.
Reading a penalty clause in five questions
- What is the unit? Days of interest, months of interest, or a percentage of the amount withdrawn.
- What is it calculated on? Simple interest on the amount withdrawn, or interest on the whole balance. The difference is real on a large certificate.
- Which band is your term in? Schedules step up at 12 or 24 months at the institutions checked. A 13-month certificate may sit in a harsher band than a 12-month one for one extra month.
- Can it touch principal? Look for the words "and then the principal" or a cap at interest earned. This is the most important line in the schedule.
- Are partial withdrawals allowed? If not, taking $2,000 out of $10,000 means closing all of it and re-depositing the rest at the rate of the day.
And two follow-ups: which circumstances the bank waives the penalty in — death, incompetence, the post-maturity window, and sometimes more — and whether interest can be paid out during the term without triggering it.
Alternatives, priced against the penalty
The penalty is what makes the alternatives worth their cost.
A no-penalty certificate charges for the exit in its rate instead of at the door; on round numbers the discount over a full term is about the size of one 60-day penalty, so it wins if there is a real chance you leave early and loses if there is not. The no-penalty page prices it.
A Treasury bill has no penalty because it has no withdrawal — you sell it at the market price, which for a short bill is close to what you paid — and its interest escapes state and local tax. HYSA vs CD vs T-bills runs the comparison.
A ladder limits the damage structurally: with money split across staggered maturities, an unexpected need costs at most one small penalty on one rung, and often none. The ladder guide shows the setup.
A savings account has no penalty and no lock, which is why emergency money lives there regardless of what certificates pay.
What to actually do
Read the penalty schedule before the rate, every time. Between two certificates a tenth of a point apart, the milder schedule is worth more than the spread — a tenth of a point on $10,000 is $10 a year; the difference between a 60-day and a 180-day penalty is $131.
Find the line about principal. If the penalty can exceed interest earned and take principal, know the month after which it cannot, and do not open the certificate if there is any chance you need the money before then.
Buy the date, not the rate. The penalty only matters if the date moves. If it might, use a no-penalty certificate, a bill, a ladder or a savings account, each of which costs less than the exit priced above.
If you must exit, do the arithmetic after tax. The penalty comes off your income on Schedule 1 without itemising; the true cost is the sticker less your marginal rate. Check Box 2 of the 1099-INT the following January.
Split large certificates. Several smaller certificates turn an all-or-nothing exit into a partial one and cap any single penalty.
Keep the waiver list. Death, incompetence and the post-maturity window are in the regulation; your bank's terms may add more. An executor or a family member should know a certificate can usually be closed without penalty on the owner's death, because that is exactly the moment nobody reads the fine print.
