With a full amortization contract, the sum of the lease payments during the term covers all acquisition and production costs and other expenses of the lessor, including financing costs and profit. In a partial amortization agreement, the lease payments to be made during the term do not cover the aforementioned costs and profit. At the start of the lease, a specific residual value is determined, which must still be provided at the end of the lease agreement and ultimately leads to full amortization.
