TL;DR — Quick Verdict
- On a $40,000 loan at a 6.96% APR, stretching from a 60-month term to a 72-month term adds roughly $1,540 in total interest; going to an 84-month term adds about $3,000 versus the 60-month baseline (modeled).
- The average new-car loan term reached 68.94 months in Q4 2025, and 35.55% of new loans now run longer than 72 months, according to Experian.
- Longer terms carry higher APRs and stack years of negative equity — you can owe more than the car is worth well into year four.
- Direct comparison: a 60-month term beats a 72-month term for total cost; a 72-month term only wins if the lower payment is the difference between buying and not buying.
- Recommendation: cap your term at 60 months when the payment fits your budget, and never let the dealer sell you a term instead of a price.
Nearly seven in ten new-car buyers now sign up for loans longer than five years. Experian’s State of the Automotive Finance Market Report puts the average new-car term at 68.94 months in Q4 2025, with 35.55% of new loans stretching beyond 72 months by Q1 2026. The math behind that shift is simple and expensive: a longer term shrinks the monthly payment while quietly inflating what you hand the lender overall. On a $40,000 balance at the 6.96% APR Bankrate reported for a 60-month new-car loan in July 2026, moving to an 84-month term can cost roughly $3,000 in extra interest. This report breaks down 60- versus 72- versus 84-month financing with modeled cost tables, a head-to-head verdict, and the mistakes that trap buyers at lenders like Capital One and captive finance arms. You will see exactly where the money goes — and how to decide which term is actually worth it for your situation. Every rate here traces to a named primary source, not a dealer’s payment sheet.
What Each Term Length Actually Costs in 2026
Start with the number the dealer won’t lead with: total interest. The monthly payment is a distraction engineered to fit your budget, not your wallet’s long-term interest. Below is a modeled comparison holding the loan amount at $40,000 and applying representative 2026 APRs — rates rise with term length because the lender carries risk longer.
The pattern holds regardless of your exact balance. Drop the monthly payment by $180 and you pay nearly $3,900 more across the life of the loan. That trade — $180 a month now for thousands later — is the entire business model behind the 84-month term. Buyers comparing auto loan APR data by credit score should note that the APR gap between terms widens further for subprime borrowers, amplifying the penalty.
How Term Length Drives Your APR — and Your Negative Equity
Two forces make long terms costly, and they compound. First, lenders price risk into the rate: the longer they wait to be repaid, the higher the APR they demand. Capital One, for example, advertised new-car financing starting at 5.64% for a 60-month term versus 5.89% for a 72-month term in mid-2026, per LendingTree. That quarter-point looks trivial until it runs across an extra year of a $40,000 balance.
Second, and more dangerous, is depreciation outrunning your principal. Picture a buyer financing a $40,000 SUV on an 84-month term. A new vehicle can lose 20% of its value the moment it leaves the lot and roughly half its value by year four. On a seven-year loan, the borrower is still paying down principal slowly while the car sheds value fast — leaving them “upside down,” owing more than the vehicle is worth, deep into year four. If that buyer needs to sell or totals the car, they cover the gap out of pocket. This is how a manageable payment becomes a financial trap, and it’s the core mechanism behind rising negative equity costs and exit strategies. The shorter your term, the faster your equity turns positive.
Delinquency data confirms the strain. Experian reported 30-day delinquencies rising to 2.00% in Q1 2026, from 1.95% a year earlier — modest, but moving the wrong direction as longer terms keep borrowers in payments longer. Buyers weighing where to originate the loan should compare credit union vs bank auto loan rates, since a lower starting APR blunts the term penalty at every length.
60-Month vs 72-Month: Which Is Better for the Average Buyer?
This is the decision most buyers actually face, because 84-month terms are often reserved for larger balances or specific new models. The average new-car loan amount hit $43,582 in Q4 2025 (Experian), so model it near there. At a $43,000 balance and the rates above, the 60-month term costs about $8,000 in interest; the 72-month term costs roughly $10,170 — a gap of about $2,170.
The 72-month term’s only advantage is cash flow: about $110 less per month in this scenario. For a buyer whose budget is genuinely tight, that breathing room has real value — missing payments is far more expensive than paying extra interest. But for a buyer who can absorb the higher payment, the 60-month term is the clear financial winner, building equity faster and freeing up the budget a full year sooner. Separating the payment conversation from the price is essential here; readers should study separating price negotiation from financing before setting foot in a finance office.
Verdict
For the average buyer who can afford the payment, the 60-month term wins decisively — roughly $2,170 less interest on a $43,000 loan and a year less debt. Choose the 72-month term only when the lower monthly payment is the difference between buying a reliable car and overextending. Never choose it simply because the dealer quoted the payment that way.
What Most People Get Wrong About Loan Terms
Three mistakes cost buyers thousands, and all three are avoidable.
Mistake 1: Shopping the monthly payment instead of the total cost. The consequence is a stretched term you never intended to take. Dealers can hit almost any target payment by extending the term. The correct action: fix your term first (60 months or less), then negotiate price and rate to fit — never the reverse.
Mistake 2: Accepting the dealer’s financing without a pre-approval in hand. The consequence is a marked-up APR that can run one to two points above what you’d qualify for elsewhere. The fix is to arrive pre-approved; compare the numbers in our breakdown of pre-approved loan vs dealer financing costs and force the dealer to beat it.
Mistake 3: Rolling negative equity from an old loan into a new long term. The consequence compounds — you finance a car you no longer own on top of one depreciating fast, guaranteeing years underwater. The correct action is to pay down or wait out the old loan, and to understand dealer financing markup and how to avoid it before signing.
A fourth, quieter error: assuming a longer term is harmless because rates are “low.” Even a 7% APR across 84 months extracts far more than the same rate across 60. Time, not just rate, is the multiplier.
Is a Longer Term Ever Worth It? Who Should Choose Each Length
Conditional logic beats blanket rules here. Choose a 60-month term (or shorter) if you can afford the payment without straining your budget, plan to keep the car past the payoff date, or want to build equity quickly for a future trade-in. This is the default recommendation for financially stable buyers.
Consider a 72-month term only if the lower payment keeps you from buying a more reliable vehicle you’d otherwise skip, you’re confident you’ll hold the car for the full term, and you’ve secured a competitive APR rather than a dealer markup. Refinancing later is a legitimate escape hatch — timing it well can recover much of the term penalty, as covered in auto loan refinancing timing and savings.
Approach an 84-month term with real caution. It can make sense only for a buyer purchasing a vehicle known for longevity, with a substantial down payment to offset depreciation, and no plan to sell before payoff. For most buyers, an 84-month need signals the car is simply too expensive — the honest fix is a cheaper vehicle, a point reinforced by the true cost of car ownership by vehicle type. One 2026 wrinkle worth weighing: the “No Tax on Car Loan Interest” deduction under the One Big Beautiful Bill Act lets qualifying buyers deduct up to $10,000 of interest annually on new, U.S.-assembled vehicles for tax years 2025 through 2028, phasing out above $100,000 modified adjusted gross income ($200,000 for joint filers), per IRS guidance (IR-2025-129). That softens — but never erases — the cost of a longer term, and it doesn’t apply to used vehicles or leases. Buyers weighing alternatives entirely should also review lease vs buy vs finance total cost comparison and, for financed vehicles, EV loan rates and applicable incentives.
Frequently Asked Questions
How much more does a 72-month loan cost than a 60-month loan?
On a $40,000 loan modeled at a 6.96% APR (Bankrate, July 2026) for 60 months versus 7.25% for 72 months, the longer term adds roughly $1,540 in total interest and keeps you in debt a full year longer. The exact gap scales with your balance and the APR spread between terms, but the longer term always costs more overall despite the lower monthly payment.
Why do longer auto loans have higher interest rates?
Lenders price risk by time: the longer they wait for full repayment, the more exposure they carry, so they charge a higher APR. Capital One, for instance, advertised 5.64% for a 60-month new-car term versus 5.89% for 72 months in mid-2026 (LendingTree). Longer terms also increase the odds a borrower goes underwater, adding risk the rate reflects.
What is the average auto loan term in 2026?
Experian’s State of the Automotive Finance Market Report put the average new-car loan term at 68.94 months and the used-car term at 67.68 months in Q4 2025 — both just under six years. By Q1 2026, 35.55% of new-car loans ran longer than 72 months, reflecting the ongoing shift toward longer financing to manage monthly payments.
Should I take a longer term and just refinance later?
It can work, but treat it as a backup, not a plan. Refinancing depends on your credit improving or rates falling, neither guaranteed. If you must take a 72-month term for cash-flow reasons, refinancing to a shorter term once your budget allows can recover much of the interest penalty — but a shorter original term avoids the risk entirely.
How We Researched This Article
This analysis combines primary market data with original amortization modeling. Loan-term prevalence, average loan amounts, average APRs, delinquency rates, and term distribution figures come from Experian’s State of the Automotive Finance Market Report, covering Q4 2025 and Q1 2026. Current benchmark APRs, including the 6.96% average for a 60-month new-car loan, were drawn from Bankrate’s weekly rate survey as of July 2026, which compiles rates from the ten largest U.S. banks and thrifts. Lender-specific starting APRs by term were sourced from LendingTree’s auto loan marketplace. Tax-deduction details reflect official Treasury and IRS guidance (IR-2025-129) on the One Big Beautiful Bill Act car loan interest provision.
The total-interest and monthly-payment figures in our comparison tables are modeled, not measured: we applied standard fixed-rate amortization to a representative $40,000 balance, holding the loan amount constant while varying term and APR to isolate the cost of term length alone. Longer-term APRs were estimated by adding modest premiums to the verified 60-month baseline, consistent with observed lender term pricing; your actual rate will depend on credit profile, vehicle age, lender, and down payment. These are illustrative scenarios, not quotes. Limitations: rates move weekly, state availability varies, and individual offers can diverge from national averages. Research last conducted July 2026. All figures were verified against named primary sources before publication.
