With regard to the concept of
"Months’ Contingency Capital = Liquid Accounts / Monthly Expenses"

Perhaps too high a number is not optimal as funds could have been deployed for other investment considerations to yield better returns. I don't have a number but 24 to 36 months seems fairly decent, buffering with inflation like 5% annual increment.

Of couse if one has already achieved a substantial amount (millions or more) then it doesn't matter. But one has to consider for unexpected events and estimated the potential cash outlay.

Thanks for sharing.
