Sounds like us. Though, we allocate the real gain to keeping up with LTC inflation.SS and and pensions cover most of our retirement expenses so we invest mainly for capital preservation. Any real return is party time.
If your portfolio just keeps up with inflation, the 30 year safe withdrawal rate is 3.33% (100 / 30 years = 3.33%). TIPS are currently at 1.11% - 1.36% real yield, so that ups the safe withdrawal rate even more. TIPS and I bonds are pegged to inflation.
I always used 40% to be conservative. Today I put in 10% after reading some responses and it still gave 100%. I also put in the “investigate” tab and see how much I can safely spend a year. Thankfully, unless we have a catastrophic issue we aren’t near that.
