is npv or roi more important 
both npv and roi return on investment are important but they serve different purposes npv provides a dollar amount that indicates the projected profitability of an investment considering the time value of money roi on the other hand expresses the efficiency of an investment as a percentage showing the return relative to the investment cost npv is often preferred for capital budgeting because it gives a direct measure of added value while roi is useful for comparing the efficiency of multiple investments
