Example: A car selling for $24,000 (or having a capitalized cost of $24,000) will have a residual value of $12,000 in three years. You'll need monthly payments of about $333 to cover the depreciation ($12,000 divided by 36 months). But if the starting price was $22,000 -- and the residual value remains $12,000 -- the monthly payments drop to about $278 ($10,000 divided by 36 months). Each month, you hang onto an extra $56.
Be especially wary that the starting price (capitalized cost) is not more than the MSRP.
While these are one-time fees, they still affect the overall cost of the lease. You'll want to negotiate everything and consider them in your computations when deciding which dealer to use.
A little research could save you BIG on interest.
