Number one fear of elderly is outliving their savings.
KNOWING where it goes monthly only goes so far.
Just like business figure you want to focus on where 80% of your expenses go because that is the likely source of material savings.
Healthcare can be a major draw. I use the BEST Medicare Advantage plan available, avail myself of ALL beneficial cost effective features, and appreciate the LOW monthly premium ($0) and $5k maximum out of pocket annual $$ limit.
It almost pays to examine your casualty insurances for coverage, need, benefits, ie umbrella, home, vehicles, etc.
It is critical to be debt free.
Consider where your $$ are saved. Between FOMO and TINA many are at risk for an equity correction and could lose 30%+. Can you tolerate that risk? Are you dependent on draws to supplement your income?
While CD and T bill yields are low, consider FR annuities for a much better return.
While I do NOT budget monthly I do track assets, especially liquid and track each YE to ensure I am growing same and hence reassured I am asset/income secure.
