The withdrawal fee or compensation is an amount some banks charge customers when a loan is cancelled or repaid before the agreed maturity date, either partially or in full. This represents lost earnings for the bank, with the compensation corresponding to the interest it will stop receiving.
This is really compensation rather than a fee, as the entity is no longer being paid for a service it has provided; instead it is being compensated for the damage resulting from the loan ending sooner than agreed. This is why some banks charge this compensation.
