This formula ignores values that arise after the payback period has been reached. In its simplest form, the calculation process consists of dividing the cost of the initial investment by the annual cash flows.

The analyst assumes the same monthly amount of cash flow in Year 5, which means that he can estimate final payback as being just short of 4.5 years. The term is also widely used in other types of investment areas, often with respect to energy efficiency technologies, maintenance, upgrades, or other changes.
