Same loan, different lengths

Borrowing $35,000 at 6.5%:

TermMonthly paymentTotal interest
36 months$1,072.72$3,618
48 months$830.02$4,841
60 months$684.82$6,089
72 months$588.35$7,361
84 months$519.73$8,657

Going from 60 to 84 months saves about $165 a month but adds about $2,568 of interest.

Longer loans usually cost a higher rate too

The table uses one rate for every term to keep the comparison fair. In practice, lenders usually charge more for longer terms. At 6.0% over 48 months the interest is $4,455; at 7.5% over 84 months it is $10,095, more than double.

The negative equity problem

Cars lose value fastest in the first years. On a long loan the balance falls slowly, so you can spend years owing more than the car is worth. That matters if the car is written off or you need to sell. Check your own situation with the negative equity calculator.
