Is an 84-Month Auto Loan a Good Idea?

Thinking of an 84-month auto loan? It may or may not be a good idea. With all types of loans, whether for a house, car, or college education, you have to consider the tradeoff between three key things:

  • how long you will be paying off the loan
  • how much each payment will be
  • the total amount you will pay for the pleasure of buying stuff with someone else’s money 

You will never get perfection in any category, but it’s important to know exactly what tinkering with getting a good deal in one category will mean for the other categories.

For this experiment sake, let’s say you want to take out a $10,000 auto loan, and you are deciding whether the loan should be 1,2,3,4,5,6, or 7 years long (12, 24, 36, 48, 60, 72, or 84 months, respectively). Let’s assume that the interest rate you are offered on all of the loans is 5 percent annually.

First, let’s consider the biggest “wallet shock” of any loan: the monthly payment. While far from the most important consideration of any loan, it is definitely critical that you will be able to afford this payment each month without straining your budget or dipping into savings.

How Much Will You Pay Each Month for Each Length of Auto Loan:

  • 12 month: $856.07
  • 24 month: $438.71
  • 36 month: $299.71
  • 48 month: $230.29
  • 60 month: $188.71
  • 72 month: $161.05
  • 84 month: $141.34

Clearly, if you are looking to minimize your monthly payment, the 84-month plan is a winner. But you probably also notice that there is not a huge difference between the payment you will be making once the number of years increases: what is the big difference, you will wonder, between a 60, 72, and 84-month loan?

The answer, my friends, is interesting.

The reason banks, car dealerships, and other financial institutions are willing to lend you money is because they make money off of you doing so. The longer you stretch out the length of your loan, the longer you will be paying someone else to be able to do so.

How Much Interest Would You Be Paying in Total on Different Loan Terms:

  • 12 month: $272.90
  • 24 month: $529.13
  • 36 month: $789.52
  • 48 month: $1,054.06
  • 60 month: $1,322.74
  • 72 month: $1,595.05
  • 84 month: $1,872.48

Is it worth it to you to pay an extra $550 to stretch the duration of your loan from 5 years to 7? Maybe. But maybe you will reconsider when you see what percentage of the money you would be spending would be going towards lining your lender’s pocket instead of paying for your car.

What Percentage of the Loan Is Interest for Each Length of Auto Loan:

  • 12 month: 2.66 percent
  • 24 month: 5.03 percent
  • 36 month: 7.32 percent
  • 48 month: 9.54 percent
  • 60 month: 11.68 percent
  • 72 month: 13.76 percent
  • 84 month: 15.77 percent

That means that if you choose the 7-year loan, a full 15 percent of the amount you pay will be going towards not your car, but straight to the bank.

So, when does it make sense to get an 84-month auto loan, and when does it not?

When It Makes Sense to Go With an 84-Month Loan:

  • If you are cash-strapped. Although I would advise you to consider taking the bus or other public transit if it is going to take you 8 years to pay off a depreciating asset that’s unlikely to last for a very long time, if you really need a vehicle and really can only afford the lowest possible monthly payment, take the loan.
  • Sorry, the above answer is the only good reason to go with an extended loan.

When It Does Not Makes Sense to Go With an 84-Month Loan:

  • If you can afford a higher monthly payment. Really—why would you prolong the agony of owing someone else money? If you are able to comfortably afford a higher monthly payment, it does not make financial sense to drag it out.
  • If you have alternative financing available. Can you borrow cash from a relative to buy a vehicle? If so, you should highly consider doing so to save yourself unnecessary interest payments.
  • If you do not really need a vehicle. If you live in a major metropolitan area with reliable public transportation, or if you can easily carpool with a neighbor, you need to ask yourself whether or not paying thousands of dollars in interest is really worth it—not to mention the high cost of maintaining, fueling, and insuring a vehicle.
