A good PVI is at least greater than 1. This indicates the present value of cash inflows (numerator) is enough to cover the initial investment (denominator). Thus, a profitable investment. For every dollar of the initial cost, the asset is expected to return more than a dollar. The higher the PVI, the better. However, the specific threshold for what's a good PVI varies according to the company, its other investment opportunities, its industry, and the project size.
