A $1,000 in a Emergency fund is NOT enough! That is not even enough in a 'oh shit fund'
is a $1,000 better than nothing YES! But it is not enough.
Shit can happen. Emergency dental work even with kick ass insurance cost me $3,000 last year.
This year I broke my foot. I have all ready spent $500 trying to get it worked on and I do not even have the Dr bill yet. I know I will have my insurance deductible at $300 and that is a total of $800 all ready out the door and that is not the cost of a new pair of shoes.
Then there is the cost of owning a house...every time something goes wrong it is big bucks. The kitchen rains, the roof needs to be replaced after a wind storm.
You can plan for some things but not for most. And if you have kids the 'oh shit fund' needs to be even higher.
Where you keep it is up to you all you need to remember is you do not want it to cost you money to take it out of that account.
