OK, I’m stumped. I need some help trying to figure out why the Leasehackr calculator doesn’t match the dealer calculation.

Please help with my calculator input. After reading this board, I know putting my trade-in towards the lease may be a bad idea, but I haven’t gotten an updated quote from the dealer yet excluding it.

Here’s the deal:

MSRP (incl. destination charge): $49,280

Dealer Discount: $3,980 (8.1%)

Mfg Rebates/Incentives: $9,400

Cash Down (via Trade-in): $10,000

Lease Term: 24 months

Residual Value: 54%

Money Factor: .00185

Sales Tax: 6.25%

My calculation:

Sale Price (MSRP - Discount): $45,300

Residual Value (MSRP X RV$): $26,611

Adjusted Capital Cost (Sales Price - Mfg Rebates - Cash Down): $25,900

Depreciation over Lease Term (MSRP - RV): $22,669

Net Depreciation (Depreciation - Mfg Rebates - Cash Down): $3,269

Depreciation per Month (Net Depreciation / Lease Term): $136.20

Lease Rental Charge ((ACC + RV) * MF): $97.15

Total Payment, pre-tax: $233.40

Total Payment, post tax (Pre-tax * 1+Tax Rate): $247.98

Now, the dealer quoted $215, so I’m a little confused there also, but first let’s deal with the Leasehackr calculator.

MSRP: $49,280

Selling Price: $45,300

Months: 24

Residual: 54%

Money Factor: .00185

Down Payment (trade-in): $10,000

Untaxed Incentives: $9,400 (not likely untaxed, but see note below)

Sales tax: 6.25%

Leasehackr calculation: $72

$72!!?

What am I missing here?

Now, the calculator assumes that the tax on the incentives is paid upfront, versus rolled into the lease (I don’t see an option to do that), but that alone doesn’t cover the difference.

So … dealer: $215, me: $250, Leasehackr: $72

I’m stumped.

Thanks for your help.
