Usage Guidance
-
This metric is intended to capture the interest calculation(s) used by the organization. Amounts of interest payment depend on both the stated interest rate and the method used to calculate it.
-
With the declining balance method, also known as the reducing balance method, interest is charged only on the product amount that the borrower still holds.
-
With the flat rate method, interest is charged on the full, original product amount throughout the entire product term. This metric is not intended to capture amortization schedules on debt products (e.g., straight line, declining balance, bullet, balloon, increasing balance, or others).
