I think one of the biggest variables that is overlooked in financial planning is what numbers are you using for your longevity numbers. Financial planners tend to want to use 95 for both or sometimes 90 for the male 95 for the female. But everybody's different. Anyway it's a big variable and so I wanted to make sure I wasn't being too conservative by having our longevity numbers too high. So I use Claude. I asked it to create me a questionnaire of all the things they would need to know to calculate our longevity ages. Things like our current lifestyle and information about our parents and sisters and brothers and aunts and uncles in terms of when they died and from what. List of medications were taking list of supplements were taking, etc. after filling that out and uploading it to Claude in addition to our quest lab reports for each of us it came back with a very nice report that showed a conservative age of most likely age and an optimistic age. Included all of the items that are working in our favor and also all the items that are working against us. So what I did is for my baseline I used the most likely numbers. Then to stress test that I created a scenario with the optimistic numbers. And then compare the scenarios, some very interesting results. Living longer lowered the chance of success which one might expect, but living longer also left us more at the end of the plan. When inquiring about this, we have more money at the end of the plan because we have more years of collecting Social security, and since I'm not going to collect Social security, either of us, until age 70, we're well beyond the break-even point in the long longevity scenario. But the reason the chance of success goes down even though value and plan goes up, as Claude explained it, is that it's five more years that the Monte Carlo simulations are using which means five more years of potential downturns in the market.
Just thought I would share this in case anyone else was interested in giving it a try. I feel I have a better, more realistic plan, of course no one knows when our time will come, so the best we can do is take our best guess based on data.
