what is a good payback period 
the best payback period is the shortest one possible getting repaid or recovering the initial cost of a project or investment should be achieved as quickly as it allows however not all projects and investments have the same time horizon so the shortest possible payback period needs to be nested within the larger context of that time horizon for example the payback period on a home improvement project can be decades while the payback period on a construction project may be five years or less
