2. Understanding the Rejection/Delay

Definition: The “Rule of 78” is a legacy interest allocation method used by many Singapore financiers to calculate early car loan settlement penalties. According to authoritative guides, this rule disproportionately front-loads interest, so borrowers who settle early pay more than expected by conventional logic. This occurs when flat-rate loans are repaid ahead of schedule, especially on COE renewal or PQP financing contracts The Truth About Rule of 78: Why Your Car Loan Settlement Penalty Is Higher Than You Think.
