Final answer:
The monthly payment and effective annual rate for a $79,500 car loan at 5.8% APR over 60 months can be calculated using specific Excel formulas that account for the terms of the loan and compounding interest.
Step-by-step explanation:
To calculate the monthly payment for a $79,500 car loan with a 5.8% annual percentage rate (APR) over a 60-month period, you can use the Excel formula PMT(D7/12, D8*12, -D6). The negative sign before the loan amount (D6) is used to indicate a cash outflow. The effective annual rate (EAR) can be calculated with the formula (1 + D7/D9)^(D9) - 1, which accounts for the compounding periods per year.
Example:
The monthly payment: =PMT(5.8%/12, 5*12, -79500)
The effective annual rate: =(1 + 5.8%/12)^(12) - 1
