CD Early Withdrawal Penalty Calculator
Cash in a CD before maturity and the bank keeps some of your interest — sometimes all of it, sometimes part of your principal too. Enter your figures to see exactly what an early withdrawal would cost.
§ 1 · The Fee
What an Early Withdrawal Costs
A certificate of deposit locks your money at a guaranteed rate — and the price of that guarantee is a penalty if you leave early. Most banks state that penalty as a number of days of interest: typically 90 days for terms under one year, 180 days for one-to-five-year terms, and 365 days for terms over five years. The penalty is taken from the interest you have earned; if there is not enough interest, the rest comes out of your deposit.
The calculator below reads your deposit, your rate, when you would withdraw, and which penalty schedule applies — then shows the interest you would have earned, the penalty, and what you actually keep. Try all three schedules at once to see the spread.

§ 3 · The Math
How the Penalty Is Calculated
The standard method treats the penalty as a number of days of simple interest on your principal:
So a 365-day penalty equals roughly one full year of simple interest on the deposit. On a $10,000 CD at 4.35% APY, that is 10,000 × 0.0435 = $435 — regardless of how long you actually held the CD. The interest you have earned by the withdrawal date, by contrast, grows with time: after one month it is only about $36, which is why an early withdrawal under a 365-day schedule can dig into your principal.
Typical Schedule by Term
| CD term | Typical penalty |
|---|---|
| Under 1 year | 90 days of interest |
| 1 – 5 years | 180 days of interest |
| Over 5 years | 365 days of interest |
These are common tiers, not a rule. Some banks charge a flat fee or a percentage of principal instead, and a few offer no-penalty CDs. Always read the account agreement before you open one.
§ 4 · Worked Examples
Two Worked Examples
Example 1 — Six Months In, 180-Day Penalty
A $10,000, 4.35% APY, 5-year CD, withdrawn after 6 months under a 180-day schedule.
Penalty = $10,000 × (0.0435 / 365) × 180 = $214.52
You keep = $215.16 − $214.52 = $0.64 of interest (your principal is intact)
Six months of interest is almost exactly cancelled by a 180-day penalty. You get your $10,000 back, but the CD earned you essentially nothing for the trouble.
Example 2 — One Month In, 365-Day Penalty
The same CD, but withdrawn after only 1 month under a 365-day schedule.
Penalty = $10,000 × (0.0435 / 365) × 365 = $435.00
You keep = $35.54 − $435.00 = −$399.46 → the penalty dips into principal
With so little interest banked, the full-year penalty cannot be covered by earnings — the bank takes the shortfall from your deposit. You walk away with about $9,600 instead of $10,000. This is the scenario the penalty is designed to make painful.
§ 5 · The Fine Print
Grace Periods & No-Penalty CDs
When a CD matures, most banks grant a grace period of 7 to 10 days during which you can withdraw or change terms with no penalty at all. After that window the CD typically auto-renews into a new term at the bank's current rate — and the early withdrawal penalty starts ticking again. Set a reminder for the maturity date so you are not silently rolled into a rate you did not choose.
If you want higher yield than a savings account but cannot promise to leave the money untouched, a no-penalty CD lets you withdraw anytime without a fee. The trade-off is a lower rate than a standard CD of the same term. For money you are certain you will not touch, the standard CD's higher rate usually wins.
§ 6 · Questions on Record
Frequently Asked Questions
What is the early withdrawal penalty on a CD?
It is a fee a bank charges if you close a CD before its maturity date, usually stated as a number of days of interest — commonly 90 days for terms under one year, 180 days for one-to-five-year terms, and 365 days for terms over five years. The penalty is taken from your earned interest and, if that is not enough, from your principal.
How is the CD early withdrawal penalty calculated?
Most banks use penalty = deposit × (APY / 365) × penalty-days. A 365-day penalty on a $10,000 CD at 4.35% APY is about $435. Use the calculator above with your own deposit, rate and withdrawal date.
How much is the penalty if I withdraw early?
It depends on your deposit, rate and schedule. Withdrawing a $10,000, 4.35% APY CD after one month under a 365-day schedule costs about $435 — far more than the ~$36 of interest earned, so you lose principal. After six months under a 180-day schedule it costs about $215, roughly all the interest you earned.
Do all CDs have an early withdrawal penalty?
Most do, but no-penalty CDs exist. They let you withdraw anytime without a fee in exchange for a lower rate than a standard CD of the same term — useful when you want more yield than a savings account but cannot be sure you will leave the money untouched.
What is the grace period on a CD?
A window — typically 7 to 10 days after maturity — during which you can withdraw or change terms without penalty. After it closes the CD usually auto-renews at the bank's current rate and the early withdrawal penalty applies again.
Can I avoid a CD early withdrawal penalty?
By holding to maturity, by choosing a no-penalty CD, or by withdrawing during the maturity grace period. Some banks also waive the penalty in limited cases such as the death of the owner. Otherwise the penalty is part of the contract you signed at opening.
