Understand the cost of an early exit
CD early withdrawal penalty calculator
Use your CD agreement or bank quote to estimate a full withdrawal. See the penalty, remaining payout and whether the charge would reduce your original principal.
How the early-withdrawal estimate works
Bank contracts differ. Use actual interest earned and the contractual penalty; a quoted dollar penalty is preferable when the agreement uses a different formula.
Penalty units and nominal annual rate
Days: penalty = P × r × days / basis; months: penalty = P × r × months / 12
Here r is the nominal annual interest rate divided by 100, not APY. Choose a 365- or 360-day basis only if it matches your contract. A quoted-dollar penalty is used directly. We do not select a bank policy automatically, cap penalties at earned interest or assume partial withdrawals are allowed.
Ally: CD terms and early-withdrawal penaltiesPayout and principal reduction
Payout is principal plus actual earned interest minus penalty. When penalty exceeds earned interest, the difference reduces principal. A penalty exceeding the entire balance is rejected so you can confirm the contract. Real bank settlement can differ because of rounding, credited interest, waived penalties or other contract terms.
A deliberately simple hold comparison
The hold estimate adds simple interest on original principal over the remaining days using the selected day basis. It excludes future compounding, reinvestment, tax effects, fees and changes in contract rates. Cost of exit here is the penalty plus that simple foregone interest, not a recommendation to withdraw or hold.
Common questions
Can an early-withdrawal penalty reduce principal?
Yes, depending on the contract. If the penalty is greater than the actual interest earned, this estimate shows the shortfall as principal reduction. Confirm the payout with your bank.
Does this price a brokered CD sale?
No. Brokered CDs sold before maturity can have market-price gains or losses and commissions. This calculator models a contractual full withdrawal, not a secondary-market sale.
