@jimmykiff It depends entirely on your life circumstances.
What are your essential monthly bills? A lot? Bigger efund. You live for free somewhere and are Very unlikely to lose that situation? Smaller efund.
You have a kid or dependent parent? Much Bigger efund.
You have family that will cheerfully take you in long term if you lose your job or housing? Or gift you thousands of dollars? Smaller efund.
You live fifty miles from work or groceries? Efund big enough to replace your car if it blows up.
You can get pregnant and would not/could not get an abortion or surrender your rights/adopt out a baby? Bigger efund.
In general, I recommend three months of expenses in an efund, six if you have a kid, and twelve if you’re a single low income parent.
But starting with Any amount, say one month ofexpenses, is good.
