Exploring the Rule of 78 [Finance]: A Guide to Loan Interest Calculation

Definition & Meaning

The Rule of 78 is a method used to calculate interest on loans, particularly in the context of consumer finance. This approach assigns greater weight to earlier payments, meaning that borrowers pay more interest at the beginning of the loan term. When a borrower pays off a loan early, they may save on interest, but this method can result in them paying more overall compared to other interest calculation methods. The Rule of 78 is also known as the sum of the digits method, reflecting its mathematical basis.

Real-world examples

Here are a couple of examples of abatement:

For example, if a borrower takes out a one-year loan of $1,200 with an interest rate of 12 percent, the total interest calculated using the Rule of 78 may result in the borrower paying a larger portion of the interest in the first few months. If they decide to pay off the loan after six months, they may find that they have paid more interest than they would have under a different calculation method. (hypothetical example)
