This just goes to show how everyone has different expenses...
Monthly expenses ..
Real Estate tax $200
Insurance on home $80
Health insurance until 65 $0
Car insurance $95
Utilities $200
Income of $3900 per month would leave us with about $3300 in spending money per month with a payed off home. Of course the biggest factor is insurance cost and real estate taxes.
My wife and I resemble these expenses. We split our costs down the middle which is about $1,250 each, then our w*rk and assets pick up the difference.
After taxes, full IRA Max contribution, flex plan and benefits - I net $2,500. This less the $1,250 in fixed costs leaves me an extra $1,250 a month. An amount I never come close to spending.
600k would do it for me, BUT I would have to do something (whereby I make a few dollars) to comfortably transition and supplement "a rainy day fund.). By the way, the aforementioned includes having a paid off house.
