Best Car Lease Calculator

I, of course, believe that my lease calculator (www.LeaseGuide.com/calc.htm) is the best that can be found.

Actually I know of one that is better, but it's for dealers and is not available to consumers. The reason it is better is that it shows exactly what a lease costs, using the dealer's own figures for interest rate (money factor), residual value, and add-on fees. These are figures that we don't have as consumers, unless we ask and get them directly from the dealer. We can guess at the figures for planning and estimation purposes, but we can't know for sure.

Therefore, for any consumer lease calculator to produce exactly the same results as a dealer's, you must input the same exact figures used by the dealer. If a dealer won't give you these numbers, you should see another dealer.
