How the Calculator Works
This calculator uses the Rule of 78 to determine the unearned interest on a loan. Here’s a brief overview:
- First, the total interest over the loan term is calculated using the annual interest rate and loan amount.
- The sum of the digits of the loan term is then computed.
- The unearned interest is the portion of the total interest that has not yet been earned, calculated by summing the products of the remaining term months and the total interest divided by the sum of the digits.
Limitations
Please note the following limitations:
- The calculator assumes that interest is calculated using the Rule of 78, a method that front-loads interest payments.
- It is applicable to loans with fixed interest rates.
- Ensure all input values are positive numbers and within valid ranges. The “Months Passed” should not exceed the total loan term.
