Understanding the Rule of the Sum of the Digits [Finance] and Its Applications
Definition & Meaning
The Rule of the Sum of the Digits, often referred to in finance, is a method used to allocate interest charges on loans over their payment periods. This approach assigns a greater portion of interest to earlier payments compared to later ones. It was commonly applied in consumer loans, particularly for automobiles. However, due to its potential to disadvantage borrowers who pay off their loans early, the U.S. government has prohibited its use for loans exceeding five years.
