Not sure I can quantify in this fashion. When working, my emphasis was to get to FI. There were still luxuries, though to some extent that is in the eye of the beholder. Before FI, the "budget" was aimed at FI. Now, it is aimed at maximizing the enjoyment of ER (in the time left). While we don't know how long we will live, we know it's a lot less than before we were FI. SO, I feel no guilt in rewarding myself occasionally for having saved diligently. Also, I have at least SOME feel for how much I CAN spend, now that I know what my "stash" is. If nothing else, I have Firecalc to let me know about what I can reasonably expect to spend. If a few luxuries fit within that, I don't ask as many questions as I used to. I am surprised that we still resist some luxuries that we could probably afford (first or bus-class vs coach for example). Nicer cars, finer dining, etc. But we are happy and do not feel in any way deprived.
Being free from the w*rkplace is such a luxury that other things seem to pale in comparison. I think that's why we rarely think too much about the subject. We are already in the "lap of luxury". It is called FIRE. YMMV
