*(and a few other parameters), would analytically and deterministicly solve for the SWR that gave a zero ending balance. Unfortunately, I cannot remember exactly when or where I saw this. I've tried searching Bogleheads, ERN, Dirk Cotton's Retirement Cafe and other internet searches but apparently haven't found the right search terms. (I did find a lot of research on the Standing Wave Ratio though! ) It was fairly compact and relatively simple, I was surprised.*

**given the sequence of returns**Does anyone know where it can be found. Perhaps someone like Siamond or one of the other hard-core number crunchers on here remembers where that might have been or what is the equation.
