Ages 47 & 48, and I use 80% of current projections, all subject to income tax. I thik that's being pretty conservative.
The last round SS fixes left those 55 & older nearly unscathed, and the AARP has only become stronger since then. We'll all be a few years older before the next SS fix, and again, I expect very little to fall on the shoulders of the retired or those near retirement.
