I always find this visual representation helpful

I have also created a lifelong spreadsheet model that factors this stuff in, but I haven’t really played a lot with it.
The visual representation above directionally guides what we are doing, but there are quite a bit of variables in our future such that modeling with any precision is difficult. Also, the representation is as of today (I assume). The social security taxation brackets are not inflation adjusted so that map will change through time. If tax rates revert in 2026 they will change again.
We are about 50/50 Roth / Traditional. We may do some more modest conversions, and would like to be mostly Roth by the time we die, such that we leave Roths in trusts for our kids, but at the same time want to keep enough traditional while we are alive such that if we ever dip into a lower bracket and/or have significant medical deductions we can take advantage of it.
