[Verse 1] When projects pile up on your desk like cards And capital's scarce, you need something smart Calculate the magic number that decides Which ventures flourish, which get cast aside Take present value, divide by what you spend This ratio reveals which roads transcend [Chorus] P-I, Profitability Index Present value over initial cost P-I, shows you what to pick When your budget can't afford to get lost Greater than one means green light go Less than one means let it go P-I, P-I, ranks them high to low [Verse 2] Project Alpha needs a million upfront Beta wants five hundred, Gamma's blunt Same cash flows streaming through the years ahead But different appetites for capital fed Alpha's P-I might be one-point-two Beta soars to two-point-eight, breakthrough [Chorus] P-I, Profitability Index Present value over initial cost P-I, shows you what to pick When your budget can't afford to get lost Greater than one means green light go Less than one means let it go P-I, P-I, ranks them high to low [Bridge] NPV tells you absolute gain But P-I reveals efficiency's domain Bang for buck in every dollar placed Capital rationing problems get erased Rank them neat from best return per bite Squeeze the most from resources tight [Chorus] P-I, Profitability Index Present value over initial cost P-I, shows you what to pick When your budget can't afford to get lost Greater than one means green light go Less than one means let it go P-I, P-I, ranks them high to low [Outro] Benefit-cost ratio in your hand Makes capital allocation understand P-I guides you through the choosing maze Maximizing value in constrained days
