The deposit is deducted from the price of the vehicle at the start of the agreement.
The customer is then required to pay fixed monthly payments over the term of the agreement and then pay the final GMFV before taking title to the vehicle. The fixed monthly payments include interest on the full amount including the GMFV (and any option to purchase fee) but excluding the deposit paid. Typically a PCP agreement will be either 2 or 4 years long.
