Not only the loan principle, but the payment.
I don't think the interest is a figure they can just plug in. The payment, interest charged, etc are fields that are filled in based on the principle and rate.
So there is really no way to fill in the finance charges.
They can play with the rate, or not correctly back-calculate the actual price of the car based on state fees, taxes, etc.
Those are more likely sources of the discrepancy.
That's why I negotiate one number, the OTD price with all the taxes, fees, etc, including trade.
I don't play the games of springing the trade on them at the last moment, because I already have an idea of where I want the difference to be if there is a trade. I come in with a bank draft if I'm financing, so my bank, USAA, whom I trust will do the calculations.
But if I'm not happy with the numbers, I walk away. No games, etc.
