How Loan Term Affects Your Payment
The loan term is the number of months you have to repay the auto loan. Common terms for new and used cars are 36, 48, 60, and 72 months. The term directly affects two numbers: your monthly payment and the total interest you pay over the life of the loan.
A longer term spreads the same principal over more months, so each monthly payment is lower. However, interest accrues over a longer period, so the total interest paid is higher. A shorter term has higher monthly payments but a lower total interest cost.
When comparing terms, it is helpful to look at a specific example. The table below uses the same loan amount and annual interest rate for each term to show how the payment and total cost change.
- Shorter terms (36, 48 months) mean higher monthly payments and lower total interest.
- Longer terms (60, 72 months) mean lower monthly payments and higher total interest.
- The interest rate you qualify for may vary with the term you choose, which can change the comparison.
Example: A $30,000 Loan at 6% APR
To make the comparison clear, take a $30,000 auto loan with an annual percentage rate (APR) of 6%. The monthly payment is calculated using the standard amortization formula:
Monthly Payment = Principal × [r(1+r)^n] / [(1+r)^n – 1], where r is the monthly interest rate (APR divided by 12) and n is the number of months.
The table below shows the monthly payment and total interest for each term. The totals include only the interest cost; they do not include taxes, fees, or other charges.
| Term (months) | Monthly payment | Total interest paid | Total cost |
|---|---|---|---|
| 36 | $912.65 | $2,855.40 | $32,855.40 |
| 48 | $704.55 | $3,818.40 | $33,818.40 |
| 60 | $580.00 | $4,800.00 | $34,800.00 |
| 72 | $497.19 | $5,796.96 | $35,796.96 |
Pros and Cons of Shorter vs Longer Terms
Shorter terms (36 or 48 months) generally mean you build equity in the car faster and pay less interest. The main downside is the higher monthly payment, which might strain your budget.
Longer terms (60 or 72 months) make the monthly payment more affordable, but you pay more interest over time. There is also a greater risk that the car’s value depreciates faster than you pay down the principal, leaving you “upside down” on the loan—owing more than the car is worth. That can be a problem if you need to sell the car or are in an accident and the insurance payout is less than the loan balance.
Some lenders may charge a higher interest rate for longer terms, which further increases the total cost. Be sure to compare the APR, not just the monthly payment, when you shop.
The right term depends on your budget and how long you plan to keep the car. A good rule of thumb is to aim for a term that lets you afford the payment but does not extend past the time you expect to own the vehicle.
- Shorter term pros: lower total interest, faster equity, sooner payoff.
- Shorter term cons: higher monthly payment, less cash for other needs.
- Longer term pros: lower monthly payment, easier to fit into a budget.
- Longer term cons: higher total interest, higher risk of being upside-down, may have a higher APR.
How to Choose the Right Loan Term
Start by deciding how much you can afford to pay each month. Use that number as a ceiling, but do not simply pick the longest term that fits. Instead, compare the monthly payment and total cost of each term side by side.
Consider how long you plan to keep the car. If you tend to keep a car for five years or more, a 60-month term may align well with your ownership period. If you like to trade in every few years, a shorter term helps you build equity and avoid being upside-down.
Also factor in the car’s expected depreciation. Cars lose value quickly in the first few years. A longer term means you are paying off a larger portion of that depreciation slowly, which increases the chance that you owe more than the vehicle is worth during the early years of the loan.
Finally, compare APRs from different lenders for the same term. A lower APR can offset some of the cost of a longer term, but the total interest will still be higher than a shorter term at the same APR.
- Set a monthly payment budget, then compare terms that fit.
- Match the term to how long you expect to keep the car.
- Beware the risk of being upside-down on a longer term.
- Get APR quotes for each term from multiple lenders.
Side-by-Side Comparison: Term Categories and Decision Criteria
When comparing loan terms, it helps to think about them in categories. Here is a side-by-side look at the main categories of loan terms and the criteria you can use to decide which one fits you best.
The table below summarizes the trade-offs for short, medium, and long terms. Use it as a decision aid when you talk to a lender.
| Category | Typical length | Monthly payment | Total interest | Risk of negative equity | Best for |
|---|---|---|---|---|---|
| Short term | 36-48 months | Higher | Lower | Lower | Borrowers who want to pay off the car quickly and have a larger monthly budget |
| Medium term | 60 months | Moderate | Moderate | Moderate | Borrowers seeking a balance between payment and total cost |
| Long term | 72 months or more | Lower | Higher | Higher | Borrowers who need a lower monthly payment and accept higher total cost |
Frequently asked questions
Is 72-month loan ever good?
A 72-month loan can be a good choice if the lower monthly payment is necessary to fit the car into your budget, and if you plan to keep the car well beyond the loan term. However, you will pay more in total interest compared to a shorter term with the same APR. You also face a higher risk of owing more than the car is worth during the loan. That risk may be acceptable if you have a stable income and a plan to keep the car for many years. It is generally better to choose the shortest term you can comfortably afford.
