Understanding the Rule of 78

This video tutorial covers Math 1332 Chapter 7 on consumer mathematics, focusing on installment buying and early payoff using the Rule of 78. It explains how to calculate unearned interest without needing the APR table, using a formula involving finance charge and payment numbers. An example with Jason's truck loan illustrates the calculation process. The video also compares the Rule of 78 with the actuarial method, discussing differences in unearned interest results. It concludes with advice on understanding loan agreements and the importance of reading fine print.
