Roth conversion questions

Here is what I managed to do with the freeware Flexible Retirement Planner. By the end of my 74th year, my tax-deferred portfolio is exhausted. From then on, it’s all Roth and HSA, except a little pulse of taxable money comes back at age 89 when I sell my house (honestly, I’ll probably vacate it sooner). Given the huge uncertainties anyway (tax policy, portfolio returns, my spouse’s lifespan, my lifespan) it gives a good enough answer. I will run it annually just to keep the boat vectored in the right direction. Hey, it sure beats $6,000 for one plan!!!

I know it looks like I’m not spending enough, but the worst 10% of investment cases have me drawing the portfolio down to $200,000 by the end of my 94th year, should God grace me with that time on earth. That’s close enough for me. I’ll have a QLAC annuity and will take Social Security at age 70 to maximize the benefit, so even if I do run it to zero, I will be OK. My kids are well-off, I’m sure they will help.
