Car Loan Term Comparison Calculator Guide
Choosing a shorter loan term means higher monthly payments but significantly less interest paid overall. A longer term lowers your monthly obligation but increases the total cost of the vehicle. This calculator side-by-side compares monthly payment, total paid, and total interest for any two loan terms you enter.
Short vs. Long Term: The Numbers
At 6.5% interest on a $30,000 loan: a 36-month term runs about $920/month and $3,130 total interest. A 72-month term drops to about $503/month but costs $6,200 total interest — nearly twice as much. The "savings" in monthly payment cost you an extra $3,070 over the loan life.
Risks of Long-Term Auto Loans
Longer terms slow equity buildup. In the first 24 months of a 72-month loan, most payments go to interest, leaving you "underwater" — owing more than the car's resale value. This creates problems if you need to sell or the car is totaled.
