I have a question regarding withdrawal rates. I "retired" at 56 and while I do some consulting and teaching, I am not anywhere near my earned income level pre-retirement. So I rely on my asset earnings to help me through. The normal rule is to not take more than 4%. When I use advanced firecalc, it allows a 95-100% success rate when I am taking anywhere from 5.3-5.8%. So I am a bit confused. I'm trying to stick to the 4% level, but there are times when I need a bit more for various things. Any advice?
