Sticker price vs amount financed on a car loan
Tax, fees, and add-ons live inside the note only if they are financed. $28,000 vs $32,000 at 6.9% for 60 months.
The window sticker is not the loan. The loan is the amount financed: agreed price, minus cash down and rebate, plus anything rolled in. Rolled-in items are sales tax in states that let you finance it, title, documentation, an extended warranty, gap, and sometimes the leftover balance from the car you traded. If you type only the sticker into a payment calculator, you are pricing a car the contract does not describe.
Two amounts, one rate, one term
APR 6.9%, 60 months. Amount financed $28,000, the sticker you might have typed: monthly $553.11, total paid $33,186.60, interest $5,186.60. Amount financed $32,000, the same car after $4,000 of tax and products: monthly $632.13, total paid $37,927.80, interest $5,927.80. The payment is $79.02 higher. Interest is $741.20 higher. The products did not cost $4,000. They cost $4,000 plus $741.20 if you keep the loan for all 60 months, because you borrowed the $4,000.
Paying those extras in cash keeps them out of P. You still pay the extras. You do not pay interest on them. That is the only difference this calculator can see. It cannot tell you whether gap or a warranty is worth buying. It can tell you the monthly cost of financing them.
How to type it on this site
The auto page asks for price and down payment. Amount financed is price minus down payment. There is no separate tax box. If you will finance tax and fees, add them to price. If you will write a check at the DMV, leave them out and keep the cash aside. A $3,000 down payment against a $32,000 out-the-door figure is not the same as $3,000 down against a $28,000 sticker.
Negative equity is the quiet version of the same mistake. You owe $6,000 on the old car and the dealer gives you $4,000 on trade. The $2,000 gap is added to the new amount financed. The new car’s sticker never shows it. The payment does. If the payment looks high for the car you see, ask for the amount financed on the contract and type that number, with down payment zero, so you are not subtracting the down payment twice.
What still is not in the payment
Ask the finance office to read the amount financed out loud before you sign. If it is not $28,000 and not $32,000, type the number they read, with down payment set to zero so you do not subtract cash twice. A one-minute retype is cheaper than discovering the $79.02 after the first draft hits.
Full-coverage insurance on a financed car can be a second monthly bill as large as the gap between $553.11 and $632.13. Maintenance on a used car can erase a low payment. A 60-month note on a car with a 36-month warranty means two years of repair risk while you still owe. None of that is interest. All of it is part of whether the car fits the paycheck.
Use the auto loan calculator twice: 28000 and 32000, down payment 0, 6.9%, 60 months. Match $553.11 and $632.13. Then set the price to the figure in the dealer’s amount-financed line, not the newspaper price. The contract wins.
