CD Early Withdrawal Penalty Calculator
Estimate the net proceeds from breaking a fixed deposit after a penalty measured in days of simple interest.
Estimate the net proceeds from breaking a fixed deposit after a penalty measured in days of simple interest. Example result: net withdrawal proceeds = $10,308.79. Compare your own inputs below. Estimates depend on the stated assumptions and are not a quote or forecast. Defaults are illustrative, not recommendations.
Your result
- Net withdrawal proceeds
- $10,308.79
- Estimated withdrawal penalty
- $98.63
- Gross interest accrued
- $407.42
- Net interest after penalty
- $308.79
With the example inputs, net withdrawal proceeds is $10,308.79. An early-withdrawal penalty may consume all accrued interest and can reduce principal under some contracts. Compare net proceeds, not only the originally quoted rate.
How to use this cd early withdrawal penalty calculator
- Original deposit: enter the amount in your selected currency. The worked example uses $10,000.00.
- Nominal annual rate: enter a percentage using 5 to mean 5%. The worked example uses 4%.
- Months held before withdrawal: enter the quantity in months. The worked example uses 12 months.
- Compounds per year: enter the quantity in count. The worked example uses 12.
- Penalty days of interest: enter the quantity in days. The worked example uses 90 days.
- Penalty day-count year basis: enter the quantity in days. The worked example uses 365 days.
Start with figures from the same statement date or planning period. Calculate once, save scenario A, then change one assumption to understand its effect. The comparison shows B minus A; a positive difference means the result increased, which is not automatically better.
Formula and calculation method
Gross balance = principal × (1 + nominal rate / frequency)^(frequency × months / 12); penalty = principal × annual rate × penalty days / year basis.
The calculator evaluates this relationship directly in your browser. The displayed precision is for readability and does not imply a guaranteed outcome. Time periods and rate conventions matter: use the exact units in each input label and avoid mixing monthly and annual values.
What the result means
An early-withdrawal penalty may consume all accrued interest and can reduce principal under some contracts. Compare net proceeds, not only the originally quoted rate.
Two worked examples
1. Illustrative planning scenario
Original deposit = $10,000.00; Nominal annual rate = 4%; Months held before withdrawal = 12 months; Compounds per year = 12; Penalty days of interest = 90 days; Penalty day-count year basis = 365 days.
Apply the stated formula with these inputs. Monetary examples use USD; percentages are divided by 100 inside the calculation. Intermediate calculations retain full precision and displayed amounts are rounded.
| Output | Calculated result |
|---|---|
| Net withdrawal proceeds | $10,308.79 |
| Estimated withdrawal penalty | $98.63 |
| Gross interest accrued | $407.42 |
| Net interest after penalty | $308.79 |
2. Simplified calculation check
Original deposit = $1,000.00; Nominal annual rate = 12%; Months held before withdrawal = 12 months; Compounds per year = 1; Penalty days of interest = 90 days; Penalty day-count year basis = 360 days.
Apply the stated formula with these inputs. Monetary examples use USD; percentages are divided by 100 inside the calculation. Intermediate calculations retain full precision and displayed amounts are rounded.
| Output | Calculated result |
|---|---|
| Net withdrawal proceeds | $1,090.00 |
| Estimated withdrawal penalty | $30.00 |
| Gross interest accrued | $120.00 |
| Net interest after penalty | $90.00 |
The second example uses simpler inputs to make the arithmetic easier to check. It is also included in the automated regression suite. These examples illustrate the model and are not market averages, live offers or personalized advice.
Assumptions and limitations
Penalty is based on original principal and simple nominal interest. Actual contracts can use different bases, minimum charges or waive penalties. Does not determine whether the institution may deduct principal; check your agreement.
Use this output to frame a question or compare consistent scenarios. Reconcile any decision involving an actual product, employment agreement or financial statement with its underlying documents. If a contract uses different rounding or timing, its result may differ from this estimate.
Frequently asked questions
Can the penalty exceed the interest earned?
Yes in this mathematical model. Whether principal can be reduced depends on the actual deposit agreement.
How do I interpret the net withdrawal proceeds result?
An early-withdrawal penalty may consume all accrued interest and can reduce principal under some contracts. Compare net proceeds, not only the originally quoted rate.
What assumptions can change this estimate?
Penalty is based on original principal and simple nominal interest. Actual contracts can use different bases, minimum charges or waive penalties. Does not determine whether the institution may deduct principal; check your agreement.
Can I compare two scenarios without creating an account?
Yes. Save scenario A, change one or more inputs to create scenario B, and compare each result with its difference. Neither scenario requires an account.
Can I use this calculator in another currency?
Yes. Select a display currency and enter every monetary input in that currency. This changes formatting only; it does not convert exchange rates or apply local laws. The static worked examples are in USD.
