The first step is to enter the details of the proposed car lease in the fields to the left:
Once you enter your details click "Calculate" and your lease information will be generated.
There are two sections in the results:
This section gives you a brief summary of the proposed car lease which includes the expected monthly payment and the total cost of the lease. If you aren't worried about specifics then this should be all you need.
This section breaks the monthly payment down into its 3 components. Depreciation Charge, this covers the loss in value of your car over the term of the lease. Finance Charge, this is like interest on a loan and pays the leasing company for using their money. Tax, this is the sales tax paid to your (usually) state government.
While this calculator should be highly accurate and give you a solid idea about the costs of your proposed car lease, it should not be relied upon to make your final purchasing decision. Always talk to your lease provider directly and fully understand what you are getting into before signing a contract.
