In planning for retiring clients, it's crucial to get an understanding of what the client's goals are in the first place - so that recommendations can be made about how to financially secure those goals. In the context of setting a spending goal, a popular delineation is to separate retirement spending into "essential" versus "discretionary" expenses - not unlike "needs" versus "wants" for accumulators - with the idea of using guarantees to secure the essential expenses, and less certain growth assets with some risk to fund the discretionary expenses (since they're 'only' discretionary and not essential, by definition).
Yet in reality, even discretionary spending still constitutes an important part of a retiree's overall lifestyle - the loss of which could be very psychologically damaging. As a result, merely securing the essential expenses of retirement and leaving the rest at risk still, in the eyes of most retirees, would constitute a failure of the overall retirement goal. Instead, clients often choose to ensure that all their spending can be sustained - by continuing to work as long as necessary (as health allows) to secure all of their goals. Does that mean the distinction between essential versus discretionary retirement expenses isn't necessarily helpful after all?
