Watch out for the Rule of 78s
Some lenders, particularly from buy-here-pay-here lenders, offer loans with a precomputed interest rate using what is known as the Rule of 78s formula. These loans front-load interest so that borrowers pay around two-thirds of their loan’s interest in the first few months.
In some states, it’s illegal to use the Rule of 78s to calculate interest on car loans with a term of five years or less, including:
