I am looking at 2017 QX60 AWD Premium package 10k miles 39 month.

I know from research I will get 63% residual and 0.0015 MF. But I will use 9 MSD so it will be 0.0006.

Here’s the Calc.

MSRP is $47,910

and I was offered invoice of $41,633

Residual is $47,910 x 63% = $30,183.30

Monthly depreciation is ($41,633 - $30,183.30) / 39 month = $293.58 / month

Monthly interest is offer price plus residual times the MF so ($41,633 + $30,183.30) x 0.0006 = $43.09 / month

So my monthly should be $293.58 + $43.09 = $336.94 and with tax $336.94 x 107% (NJ) = $360.53

With $1,500 or so fees + first month and the $4,050 for the MSD.

But the number dealer gave me was $396.80 per month. Did I calculate wrong somewhere? why is there so much difference?

Thanks.
