What breaking early costs you
Breaking early leaves you with less than holding to maturity.
That penalty is larger than the whole balance, so it has been capped — a bank cannot take more than the account holds. Your net proceeds are $0.
For reference, holding this CD to its full 5-year term would mature at $0.

How the early-withdrawal penalty is figured
First the calculator grows your deposit to the withdrawal date with the standard compound-interest formula, giving the balance at withdrawal:
balance = P (1 + r/m)m·t
where P is your deposit, r the annual rate, m the compounding periods per year and t the years held before cashing out. The penalty is then subtracted from that balance to give your net proceeds. Banks express the penalty four ways, so you pick the one your disclosure uses:
months of interest = P · r · (months / 12), flat amount = the fee itself, % of deposit = P · pct, or % of interest = (balance − P) · pct.
The first three are all charged on your principal, so they can exceed the interest you have earned and eat into your original deposit — exactly what some banks do, and no floor is applied. The fourth is charged on interest alone, so it can never touch your deposit. In every mode the penalty is capped at the balance itself, because a bank cannot collect more than the account holds. Thelost value figure compares your net proceeds against simply holding to maturity.
One penalty, three exit points
$10,000 at 4.5%, compounded monthly, on a 5-year CD with a 6-month early-withdrawal penalty. The penalty is a flat $225 every time — what grows is the value you throw away by leaving sooner.
One year: the penalty bites hardest
net proceeds$10,234.40
- One year in, the CD holds $10,459.40. The 6-month penalty takes a flat $225, leaving $10,234.40.
- You forfeit $2,283.56 against the $12,517.96 this CD reaches at maturity — the most of the three exits.
- That $225 penalty is roughly half the $459.40 of interest earned so far.
Breaking at year one nets $10,234.40 — the same $225 penalty, but the biggest pile of forgone growth.

net proceeds$10,714.90
- By year two the balance is $10,939.90; the penalty is still $225, so you net $10,714.90.
- Lost value falls to $1,803.06 — waiting the extra year kept $480.50 more on the table.
- The penalty has not moved from year one, yet the sacrifice is smaller.
Two years in nets $10,714.90; the $225 penalty is unchanged, but the cost of leaving has shrunk.

net proceeds$11,743.14
- With one year left, the CD is worth $11,968.14; after the same $225 penalty you net $11,743.14.
- Only $774.81 of maturity value is left behind — about a third of what breaking at year one costs.
- The penalty is identical to every other exit; by now nearly all the interest is already earned.
At year four you net $11,743.14 — the penalty unchanged, the forfeited value at its smallest.

Breaking a CD early, in plain English
- ▸The penalty is set when you open the CD. It does not change with market rates — check your account disclosure for the exact months or fee and enter that figure above.
- ▸A months-of-interest penalty can cost more than you have earned. On a short hold you may get back less than your deposit; the calculator shows that honestly rather than flooring at your principal.
- ▸Compare the cost against the alternative. If a new CD or high-yield account would out-earn your current one for the remaining term even after the penalty, breaking early can pay off.
- ▸No-penalty CDs exist. They allow a full withdrawal after a short initial window in exchange for a slightly lower rate — set the penalty to zero to model one.

Frequently asked questions
How is a CD early withdrawal penalty calculated?
The most common form is a set number of months of interest on your principal: penalty = P · r · (months / 12), where P is your deposit and r the annual rate. A $10,000 CD at 4% with a 6-month penalty gives 10,000 × 0.04 × 0.5 = $200. Banks also express the penalty three other ways — a flat dollar fee, a percentage of your deposit, or a percentage of the interest earned — and all four are supported here.
Can a CD early withdrawal penalty take my original deposit?
Yes. In the U.S. banks are allowed to charge a penalty larger than the interest you have earned, so on a short hold the penalty can dip into your principal and you get back less than you put in. This calculator does not hide that — it applies no floor at your deposit. The one limit is that a bank cannot collect more than the account actually holds, so the penalty is capped at the withdrawal balance and your net proceeds never go below zero.
What is a typical early withdrawal penalty on a CD?
It scales with the term. Short CDs (under a year) commonly charge about 3 months of interest; 1–3 year CDs often charge 6 months; 4–5 year CDs frequently charge 9–12 months, and some longer CDs more. Always read your bank’s disclosure — the penalty is set at account opening and varies widely, so enter your own figure above rather than trusting a rule of thumb.
Is it ever worth breaking a CD early?
Sometimes. If rates have risen enough that a new CD would out-earn your current one even after the penalty, or you genuinely need the cash, breaking early can make sense. Use the net-proceeds and lost-value figures above to see the real cost, then compare it against what the money could earn elsewhere for the remaining term. If the penalty is charged as a percentage of interest, breaking very early costs little because little interest has accrued.
Do all CDs charge an early withdrawal penalty?
Most do, but not all. "No-penalty" CDs let you withdraw the full balance after an initial waiting period (often 6–7 days) with no charge, usually in exchange for a slightly lower rate. If you hold a no-penalty CD, set the penalty here to zero to see your balance at withdrawal as your net proceeds.
