Compare totals before payments
Lenders often lead with the monthly payment, which a longer term can make look small. The total cost shows what the loan really charges.
How the calculation works
Total cost = payment × months + fees − amount borrowed
For $20,000, Offer A at 9.5% for 36 months costs $640.66 a month and $3,064 in total. Offer B at 7.9% for 60 months with a $600 fee costs $404.58 a month but $4,874 in total, because the lower rate runs for two more years.
Then check affordability
The cheaper loan is not always the right one if its payment strains the budget. A lower payment with the option to prepay can work, if the loan has no prepayment penalty and you actually make the extra payments.
