1. First, calculate the total amount of interest paid over the 30-month loan period:
Interest paid = Monthly payment x Number of months
Interest paid = $122 x 30 = $3,660
2. Next, calculate the total cost of the car if you finance it, including both the principal (the original price of the car) and the interest:
Total cost with financing = Principal + Interest paid
Total cost with financing = $2,695 + $3,660 = $6,355
3. Finally, calculate the savings by paying cash by subtracting the total cost with financing from the cash price of the car:
Savings = Cash price - Total cost with financing
Savings = $2,695 - $6,355 = -$3,660
Therefore, by paying cash for the used car, you would save $3,660 compared to financing it with monthly payments.
