Your business uses the vehicle while paying a rental fee rather than a repayment. The monthly rental is determined by the initial cost of the vehicle (excluding VAT), the period of the finance lease and the residual value, which is the estimated future value of the vehicle at the end of the finance lease period once depreciation is taken into account, plus interest.
Although you never take ownership, at the end of the finance lease contract a payment equivalent to the residual value is payable. Usually, this means that the vehicle is sold and a proportion of the proceeds of the sale are returned to the lessee.
Most finance lease companies will offer a number of payment options to suit your cash flow. You can lower the monthly rental with a balloon payment at the end of the contract, or you can pay the entire cost in monthly rentals (normally referred to as a fully amortised Finance Lease), in which case you may be able to extend the finance lease with a secondary rental (sometimes called a peppercorn rental).
