To calculate the monthly lease payment, we need to use the formula:
Monthly Payment = Depreciation + Finance Charge
The depreciation represents the portion of the car's value that is lost during the lease period, while the finance charge is the interest charged on the lease.
First, let's calculate the depreciation:
MSRP = $51,500
Residual Value = 49% of MSRP = 0.49 x $51,500 = $25,235
Depreciation = (Negotiated Price - Residual Value - Down Payment) / Lease Term
Depreciation = ($49,000 - $25,235 - $4,000) / 36 = $541.53
Next, let's calculate the finance charge:
Lease Balance = (Negotiated Price - Down Payment) - Residual Value
Lease Balance = ($49,000 - $4,000) - $25,235 = $19,765
Money Factor = Annual Interest Rate / 2400
Money Factor = 7.8% / 2400 = 0.00325
Finance Charge = Lease Balance x Money Factor
Finance Charge = $19,765 x 0.00325 = $64.26
Finally, we can calculate the monthly payment:
Monthly Payment = Depreciation + Finance Charge
Monthly Payment = $541.53 + $64.26 = $605.79
Therefore, the monthly lease payment is $605.79.
