Example: Dealer financing vs car loan
Who saved more money?
Julian and Clay have both purchased new cars for $20,000 each. Julian opts for a car loan while Clay takes on a financing option from the dealership. Who chose the better financing option?
Car loan
Julian earns $60,000 per year and has minimal consumer debt. His credit score is fairly good, and as a result, the bank is only too happy to give him a loan to buy a car. Julian's car loan comes with a 5.5% interest rate for a 5-year period and he pays $432 in monthly repayments. At the end of the loan, he will have paid a total of $3,302 in interest fees, bringing his total amount to $23,302 when all is said and done.
Dealer financing
Clay only earns $35,000 per year and has been carrying a balance of several thousand dollars on his credit card for a few years now. He gets turned down for an auto loan from the bank, so he begins hunting around for a dealership that will finance his car. He finds 2 rival sellers who are both willing to procure a loan for him.
Using the first one's offer, he successfully negotiates a better deal with the second seller. Happy to keep Clay from giving his business to a rival dealership, the seller offers him a 72-month loan with no down payment and a 4.5% interest rate. Clay accepts and drives away with his new car. In the end, he only pays $359 per month in repayments and a grand total of $3,231 of interest over the whole term of the loan, bringing his overall amount to $23, 231.
In the end, Clay will pay $71 less than Julian without having to make any bulk payment upfront and with a cheaper monthly repayment. Not bad for a guy with a much smaller salary and a higher debt load. It's true that Clay is stuck paying his loan off for a longer time than Julian, but it's also true that Julian would be unlikely to convince the bank to give him the interest rate that Clay is getting.
Of course, this scenario could have gone very differently. Had there been no rival dealership to contend with, the dealer who gave Clay a loan might not have sweetened the deal as much as he did. Given Clay's below-average financial situation, he could've easily been charged a significantly higher interest rate and ended up paying more than Julian.
