Calculator guide
Understanding CD Early Withdrawal Calculator
An early CD withdrawal should reconcile accrued interest, the bank's penalty, tax on any positive net interest, and estimated cash proceeds.
Calculation method
How the calculation works
Estimate accrued simple interest through the withdrawal month, subtract a penalty expressed in months of interest, and show proceeds before and after an entered tax estimate. Calculate monthly simple interest, multiply by months held, subtract the penalty months, apply tax only to positive net interest, and add the result to principal.

The penalty is only one part of the decision.
Worked situations
Practical examples
- A three-month penalty removes three months of modeled interest.
- If penalty exceeds accrued interest, proceeds can fall below principal.
- Tax is applied only to positive net interest here.
Better inputs
Useful tips
- Ask the bank for an exact withdrawal quote.
- Check partial-withdrawal rules.
- Compare borrowing or other liquidity sources carefully.
Before relying on the result
Limitations and common mistakes
- Actual products may use daily accrual, minimum penalties, principal invasion, partial-withdrawal rules, and term-specific schedules.
- Tax treatment varies.
- The result is not a bank quote.
