How the car payment calculator works
Payment thinking is how overbuying happens
"What monthly payment can I do?" is the finance office's favorite question because any car fits any budget at the right term. 72–84 month loans make $50k trucks "affordable" while doubling interest and guaranteeing negative equity for years. Price, term, and total interest come first; the payment is arithmetic afterward.
Where the extras stack
Sales tax applies in most states to the price (sometimes minus trade-in), doc fees run $100–800 by state, and registration/title add more. Rolled into the loan, they all accrue interest — $600 of fees at 6.9% over 60 months costs about $713. Pay fees in cash when you can; finance the car, not the paperwork.
The term trade-off, quantified
Same car, 60 vs 72 months: the payment drops ~10% but total interest rises ~20–25%. A useful rule: finance for the fewest months that keep the payment sane, and never beyond the car's realistic life with you. The 84-month loan is a guaranteed equity trap — depreciation outruns principal for most of its life.
