In the business world, Net Present Value (NPV) has long been an essential calculation when making investment and program decisions. The NPV formula helps managers focus on four essential truths about their financial decisions. Like Net Present Value, Net Present Joy would assess all immediate and future joy created by the decision in question, discounting future joy a bit since we’d certainly prefer to be joyful now rather than later. And, of course, the calculation would deduct all current and future grief associated with the initiative (emotional, organizational, logistical, etc.), adjusted to present value.
