how long is a rope ?
it is no different than saying how much do i need to earn while working ?
there is no answer . we all have different wants and needs , different area's . for many life is not just about paying bills . we can easily spend 2x our budget just traveling . my answer would be " as much money as you can get "
we have exceeded in retirement the last 2 years what we spent while working . we have time , and time can cost money ,
we live in queens in nyc . just rent , healthcare costs and our long term care premiums clock in at 40k a year . that is with nothing else and before taxes so comparing to others is silly .
Would you mind sharing what you pay for each of these?
