What an FD premature withdrawal estimate tells you
An FD premature withdrawal calculator estimates a possible settlement when a fixed deposit is closed before its booked maturity. It uses your principal, the original term, the time actually held, the rate applicable to that shorter period, and the penalty reduction stated by the provider. The result helps you compare scenarios; it is not a bank quote or a promise that a request can be accepted.
The important distinction is between the rate shown when the deposit was opened and the rate that the provider applies to the period completed. A deposit booked for two years but closed after twelve months may be recalculated using the rate for a one-year term. If a penalty also reduces that rate, the estimate should apply both assumptions to the time held rather than charge a made-up flat fee against principal.
This page keeps those inputs visible. Enter the product's actual-period rate and the penalty from its current terms, then compare an estimated early payout with a separate full-term scenario. For example, the amount projected at twelve months is not directly comparable to the amount projected at the original two-year maturity unless you account for the extra year and its interest.
